transpartent=destination setting fails with runtime error
by Stefan Lauterbach 03 Sep '12

03 Sep '12

*In the latest versions of stunnel including stunnel-4.54b8, activating the option for transparent destination with transparent=destination fails. The following error is found in the log with this configuration (tested on CentOS 6.2 and 6.3): INTERNAL ERROR: No target for remote socket This bug seems to be introduced with version 4.51 by rewriting the code and introducing additional sanity checks for the configuration. The following patch seems to resolve the problem: --- src/client.c.~1~ 2012-03-05 12:11:06.000000000 +0100 +++ src/client.c 2012-08-27 00:29:36.000000000 +0200 @@ -303,7 +303,7 @@ c->bind_addr=NULL; /* don't bind */ /* setup c->remote_fd, now */ - if(c->opt->option.remote) { /* try remote first for exec+connect targets */ + if(c->opt->option.remote || c->opt->option.transparent_dst) { /* try remote first for exec+connect targets */ c->remote_fd.fd=connect_remote(c); } else if(c->opt->option.program) { /* exec+connect uses local fd */ c->remote_fd.fd=connect_local(c); *

MySQL replication + SSL/stunnel
by Gareth Evans 27 Aug '12

27 Aug '12

Hello, I'm failing miserably to implement replication over any kind of SSL (that is, MySQL's native (alleged) SSL support) or stunnel. I'd be grateful for any tips or advice. I have tried using OpenSSL and MySQL in various flavours: CentOS 6.2, OpenSSL v1.0.0, MySQL v5.1.63 Ubuntu 12.04, OpenSSL v1.0.1, MySQL v 5.5.24 and stunnel4 on both - certs created with OpenSSL in each case. I get an eror 1045 access denied from the MySQL native SSL approach, and mysql -u ejbkslave -pejbkslavepw -h127.0.0.1 -P3307 ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 104 from stunnel (connecting two Ubuntu 12.04 VM's on my PC, with the latest updates) - if you know what causes this error and/or could point me towards some good documentation, I'd be grateful. I've copied and amended stunnel.conf-sample and just added debug and accept/connect info in each case. I've seen various reports around the web that OpenSSL+MySQL don't work together at the moment, but it seems some people can repicate the problem while others can't - I've tried the previous version of OpenSSL (1.0.0e on Ubuntu) still without success. Most frustrating!! Thanks Gareth

Stunnel performance about multiple session
by Yuqiong Sun 27 Aug '12

27 Aug '12

Hi, I am using stunnel as an encrypted channel between one server and multiple clients. Each client will transfer a very small piece of data every 20 seconds. Therefore I want to compare the tradeoff between maintaining multiple sessions with tearing down and re-establish connection every time. I read the performance table in stunnel doc and got a brief idea, but I hope to evaluate the performance for my specific hardware and software setup to make a better decision. I guess my question is how to measure the Max. concurrent sessions? Should I start multiple stunnel instances on client side? Also, how can I tear down a connection automatically after each time data transfer? Thanks Yuqiong

Behavior
by Javier 17 Aug '12

17 Aug '12

Hi, I want to report 2 different behaviors, one, related to logs and, the other, to close delay. - About the logs, there is a funny thing. If you reload stunnel.conf the log style and amount of information differs from the starting one. I'm under Windows 2000 and these are the general options in stunnel.conf: debug = debug delay = yes output = stunnel.log fips = no The differences can be seen in the attached text file. First part is how is being seen if you don't reload the conf file. The second, after you reload. I, by myself, prefer the second log style. - About the close delay, I don't know when it started to happen (maybe in the version you removed the multiple instance of stunnel or maybe later), but what happens is that stunnel delays about 1-2 seconds to close. It didn't happen before. It was immediately. And has nothing to do with how many services you have, it delays with one service or ten services or… whatever. My system specs, the same as above. But it happens in Windows XP as well, and with the latest 4.54 beta too (the one that has removed the annoying app error (thank you so much for this :-) )). Have a look to them ;-) and confirm if possible :-) Thanks.

Stunnel high memory usage?
by Matt Wise 16 Aug '12

16 Aug '12

We use Stunnel 4.5.2 in our environment of Ubuntu 10.04/12.04 systems in various clouds. We're leveraging PGPool for SSL encryption of a lot of different types of traffic ... Zookeeper, Postgresql, and AMQP traffic are some examples for us. Mostly everything works great .. its fast, and very reliable. I've just noticed though that on a particular group of machines we are seeing really high memory usage on the Stunnel process that seems to grow and grow over time. I found this Stunnel process using over 350MB of ram yesterday ... and on an m1.small in Amazon, thats a big chunk! Here's our client config file: > cert = /etc/stunnel/localhost-pgpool.pem > key = /etc/stunnel/localhost-pgpool.key > CAfile = /etc/stunnel/localhost-pgpool_ca.pem > verify = 2 > delay = no > sslVersion = TLSv1 > client = yes > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/localhost-pgpool.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = 2 > session = 86400 > debug = 4 > [localhost-pgpool] > accept = 127.0.0.1:5001 > failover = rr > connect = prod-pgpool1-uswest1:6433 > connect = prod-pgpool2-uswest1:6433 My first thought was that perhaps the Session cache was too large... so I dropped it to '3600'. Now instead of 360MB, I'm seeing Stunnel sit at around 170MB. Is the session ID cache just caching thousands and thousands of new session IDs without properly re-using them? It seems like the session ID cache should never have more than: Currently_Used_Session_IDs + Session_IDs_unused_but_last_used_within_the_last_hour Any thoughts on what might be going on? --Matt

Application Failed to Initialize Properly (0xc0150002)
by Thomas Eifert 09 Aug '12

09 Aug '12

New problem here. Stunnel version 4.53. I just did a fresh install of Windows XP Pro x86 SP3, and did all the Windows updates as well. Whenever I try to launch Stunnel or install the service, I get the error: "Application Failed to Initialize Properly (0xc0150002)" I've never seen this before. I thought it might have something to do with not having the Visual C++ Redistributables, so I installed those too, with the same result. Has anyone else seen this issue?

Stunnel waits for a long time if client does not negotiate SSL
by Denis Solovyov 09 Aug '12

09 Aug '12

Hello, I use stunnel 4.53 to provide pop3s for existing pop3 service. I start stunnel from xinetd, and then exec pop3 utility from stunnel. If a legal pop3s client connects to a server, everything's fine. But if I try to do "telnet host 995" with a simple telnet client and then just do nothing (or even close telnet client without quitting) stunnel process keeps waiting for a very long time (actually maybe forever, I just kill it). The last line in log in such case "Service [stunnel] accepted connection from xx.xx.xx.xx:xxxx". No stunnel TIMEOUT* options have effect in this situation. What can I do to avoid such "waiting"? Maybe stunnel should have something like "SSL negotiation timeout"? Or is there a way to emulate it? (Analyzing `ps` or `netstat` is a bad idea of course.) With the best regards, Denis Solovyov

Hi Thomas, I have the exact same error when trying to run stunnel on a virtual XP machine under windows 7. I asked here and the only reply I got was that it sounded like a configuration problem. I have tried everything I can think of, but to no avail. I just gave up trying in the end. Wednesday, August 8, 2012, 2:20:43 AM, you wrote: > New problem here.

Getting Stunnel to Work Under Windows 7 64-bit
by Hacker, Dietmar 06 Aug '12

06 Aug '12

Some thoughts about a thread from may: Stunnel works ok under Windows7 64bit. But: There are some windows7-specific security restraints one should be aware of: Windows7 does not allow programs to have write-access to c:\program files and c:\program files (x86) (win7 64bit). You can find the logfile in hidden directory c:\users\Youruser\appdata\local\virtualstore\program files\stunnel\stunnel.log ( Youruser is the windows user which started stunnel ) If you want a common logfile for all users, either you install stunnel in another writeable directory (security risk ?) or if installing in program files change your stunnel.conf file to have the log file in a writeable directory e.g. c:\temp or the standard common data directory c:\programData (also a hidden directory ) I use stunnel as a service and defined "output = c:\programData\stunnel\stunnel.log" stunnel writes there and only users with admin access could change the logfile.

Newbie: Success, now failure???
by Roger Bohl (Sr.) 25 Jul '12

25 Jul '12

For several days, I've been using Stunnel (with Blat) successfully (possibly with no intervening re-boots). A day or so ago, the system was re booted Today, however, Stunnel failed. I got the following Stunnel reply message: No limit detected for the number of clients stunnel 4.53 on x86-pc-mingw32-gnu platform Compiled/running with OpenSSL 0.9.8s-fips 4 Jan 2012 Threading:WIN32 SSL:+ENGINE+OCSP+FIPS Auth:none Sockets:SELECT+IPv6 Reading configuration from file stunnel.conf FIPS mode is enabled Compression not enabled Snagged 64 random bytes from .rnd Wrote 1024 new random bytes to .rnd PRNG seeded successfully Initializing inetd mode configuration Certificate: client.pem Certificate loaded Key file: client.pem Private key loaded SSL options set: 0x00000004 Accept option is not allowed in inetd mode Remove accept option or define a [section] Server is down The stunnel.conf file in the Stunnel directory is: CAfile = cert.pem cert = client.pem client = yes RNDfile = .rnd [gmail smtp] ; (I may have had this in or out before.

Except, possibly, for removing ;[comment] lines, no other changes occurred. Can somebody give me a clue as to the cause, and suggest the fix. I'm running Windows Vista.

stunnel and http
by John 23 Jul '12

23 Jul '12

I am running the latest stunnel for Windows on 64-bit Win7 as an application, not as a service. I simply unzipped everything to one folder, configured the "stunnel.conf" file; and when I need to run the program, I can open a command prompt in its folder and type "stunnel stunnel.conf". It then reads my stunnel.conf file and works its magic. This works fine for capturing the data from those programs which I can configure to use localhost and a specific port because I can configure stunnel.conf with accept = ip.address:port Now I have a program that I want to use to download some text files from the internet using http or https. However, this program cannot be manually configured to make a connection with a certain IP and port. Instead, I have to give it an alias-like name, which it then maps to one of several different domain names, makes a DNS query for the IP and transmits to that address the instructions for downloading some text files. So, is it possible to have stunnel "capture" any and all http transports (port 80) or https transports (port 443) from a specific program, regardless of which IP that connection was destined for, so that I can then direct this data traffic from stunnel to socat or from stunnel to an http proxy which I can manually direct to a specific connection? Is this a kind of thing for which stunnel can be used? If so, where can I find the instructions for setting it up? Thanks.

Esto me sigue sin quedar claro. Ya perdonarás. Una (Objetivo) está conectada a un router, que sirve internet a una red local, pero que no tiene redirigidos los puertos a la máquina que tiene el servidor http. Esta no tiene acceso a internet porque no se le ha configurado una puerta de enlace y además no la pueden alcanzar porque no hay puertos redirigidos hacia ella. Hasta ahí, todo bien ;) Lo que quería saber es si la máquina que hace de Servidor hacia internet está en la misma subred local o no que la máquina objetivo. El que la máquina objetivo vea al servidor no implica necesariamente que el servidor vea al objetivo. Además, si está conectada al mismo router, porque decías que era accesible desde internet. Lo que entiendo es que quieres redirigir el tráfico proveniente al servidor desde el exterior al objetivo http. Si el servidor, ve a la máquina http, bastaría con decir en la configuración de stunnel que conecte con el servidor http de esa maquina indicándole la ip:puerto. Por eso te dije que no tenía mayor complicación. En esa configuración no hace falta que la máquina objetivo tenga un servidor stunnel y viceversa para comunicarse entre ellos. La comunicación entre el servidor y la máquina objetivo puede ser abierta sin problemas. Lo importante ya existe, que el servidor haga de puente ssl entre internet y el objetivo http. > Durante el día de hoy lo he conseguido hacer más o menos usando > pppd y stunnel entre 2 linux pero no sé si sería posible hacerlo > sólo con stunnel (y *ifconfig*, *ip*, *route* o similares).

Reverse tunnel with middle server
by Jorge A. 18 Jul '12

18 Jul '12

Hi everyone, I've search into archives trying to found a solution for my problem without success. The problem is simple: make a machine available on HTTP port when it's behind a e.g. common DSL. I have a middle server for which I have full access to install any program, linux. What I was trying to do is the following: Three machines: Middle server (Server), Target (linux machine behind DSL) and Client. Same stunnel version on both Server and Target. Latests. Server is available on the Internet, running stunnel Target is behind a nat router, e.g. inside a common DSL. I assume this must run stunnel as well. Client connects to Server and Server forwards traffic to Target seamlessly. As far as I know, running stunnel on client mode from e.g. Target and trying to connect to whichever service on Server does not work on reverse: you cannot connect backwards to target. Am I correct? If not, how do I configure both ends and how do I know port to use to connect to Target (log file?) ? What I've tested: 1. Run stunnel on Server on server mode accepting ('accept') connections on a fixed port, e.g. 5000. Here, as far as I know, you must define the 'connect' directive to forward traffic to either local or remote host. The problem is, from Server, you don't know Target ip nor it's accessible 2. Run stunnel on Server and, on Target launch stunnel on client mode to try Thanks in advance and congratulations as it's a great piece of software. Best regards, Jorge

Stunnel on WIndows Server 2008 R2 SP1 x 64 fails - Microsoft.VC90.CRT.MANIFEST

Hi Stunnel users, I am trying to run stunnel "4.53 installer.exe" on a MS Windows Server 2008 R2 SP1 64 Bit (under VMWARE Workstation 6.5 as a virtual system; Physical Host OS is WIN7 Ultimate 32 BIT) The installation of stunnel was done as an "Administrator" and it ran through without issues.

Conf question: HTTP to HTTPS with SNI
by John Moser 03 Jul '12

03 Jul '12

I have a particular task I need to accomplish in which an HTTP-only caching proxy server is to accept SSL. The architecture in mind is as follows: - Receive request { HTTP request: - Received by caching proxy at localhost:80 HTTPS request: - Received by Pound - Decoded to HTTP - X-FROM-SSL header added - Forwarded to localhost:80 (caching proxy) } Proxy receives HTTP request - Perform caching - If X-FROM-SSL, forward to localhost:8088 - Else forward to HTTP server It is at this point that two design options come into play, both using stunnel. Either use SNI or use stunnel and HTTP. Via SNI, this would appear as follows: Stunnel receives HTTP request - Forward to https://http-server:443/ with SNI This of course requires that stunnel can read the 'Host' header out of an HTTP request and use that for SNI automatically (there's some 300 virtual hosts on that server). If not, this is infeasible. Which is my question, of course: can this be done? If this isn't an option, then the next logical way to handle this problem is: Stunnel receives HTTP request: - SSL encrypt - Forward to http-server:8443 http-server receives HTTP over stunnel - stunnel receives on http-server:8443 - Decrypt and forward to http://localhost:80/ In this way the entire connection would be encrypted, and the HTTP server would see the Host: header and use that to figure out the virtual host etc. Is that the better/only way?

more than 1000 concurrent connections?
by Trenton Ashburn 03 Jul '12

03 Jul '12

Hi There - I'd like to use stunnel as the SSL termination point for a bunch of persistent TCP connections. I'm running it on an EC2 instance and it's only allowing me about 1000 concurrent connections. It doesn't matter if the connections come from one client IP or two. How can I raise this limit? I've already raised the OS tcp connection limit with ulimit and it doesn't improve things. Thanks, T

Re: [stunnel-users] Interoperability problems with .net client software
by josealf＠rocketmail.com 30 Jun '12

Not as far as I know. You need to check with the client application developers. Maybe they can use a debugger to trace the program flow and see where and why it fails (assuming they understand the protocols and the tools). The application must be coded to present the certificate, and my guess (just a guess), is that it isn't or is blocking before getting to that point. -----Original Message----- From: ProPharma Systems AG - Gregor Bürgisser <g.buergisser(a)propharma.ch> Date: Fri, 29 Jun 2012 06:59:14 To: <josealf(a)rocketmail.com> Subject: Re: [stunnel-users] Interoperability problems with .net client software Yes I did.

I would like to install stunnel on 64-bit Win7, and I would like to know whether it is possible to do so by just unzipping the downloaded files into one folder and then clicking on the main executable, that is, to avoid making registry entries, etc. I would like to have a minimal impact to whatever extent is possible. Can it be done in this way, or does it need the whole shebang installer procedure to be run?

Stunnel, Pan and the SSL23_GET_SERVER_HELLO:unknown protocol
by mike 28 Jun '12

28 Jun '12

Hello All, Running Debian 6.0, stunnel4 and Pan 0.133 I have set up Pan and installed stunnel so that I can use ssl with nntp. Installing Pan and stunnel was easy. I've edited Pan to use localhost:119 and edited my config file in stunnel to point to my nntp server. I have allowed nntp in my hosts.allow for ALL:ALL. The problem I am running into is that Pan does not connect. I get the following error: Error reading from localhost. Connection reset by peer Checking with the following openssl command produced this error: root@triglav:/etc/stunnel# openssl s_client -ssl3 -connect localhost:119 CONNECTED(00000003) write:errno=104 Looking at the logs for stunnel I see many repetitions of this message: 2012.06.25 14:18:26 LOG7[16355:3074153328]: nntp started 2012.06.25 14:18:26 LOG7[16355:3074153328]: FD 13 in non-blocking mode 2012.06.25 14:18:26 LOG7[16355:3074153328]: TCP_NODELAY option set on local socket 2012.06.25 14:18:26 LOG7[16355:3074153328]: Waiting for a libwrap process 2012.06.25 14:18:26 LOG7[16355:3074153328]: Acquired libwrap process #0 2012.06.25 14:18:26 LOG7[16355:3074153328]: Releasing libwrap process #0 2012.06.25 14:18:26 LOG7[16355:3074153328]: Released libwrap process #0 2012.06.25 14:18:26 LOG7[16355:3074153328]: nntp permitted by libwrap from 127.0.0.1:59451 2012.06.25 14:18:26 LOG5[16355:3074153328]: nntp accepted connection from 127.0.0.1:59451 2012.06.25 14:18:26 LOG7[16355:3074153328]: FD 14 in non-blocking mode 2012.06.25 14:18:26 LOG6[16355:3074153328]: connect_blocking: connecting 209.197.15.238:119 2012.06.25 14:18:26 LOG7[16355:3074153328]: connect_blocking: s_poll_wait 209.197.15.238:119: waiting 10 seconds 2012.06.25 14:18:26 LOG5[16355:3074153328]: connect_blocking: connected 209.197.15.238:119 2012.06.25 14:18:26 LOG5[16355:3074153328]: nntp connected remote server from 192.168.2.56:51455 2012.06.25 14:18:26 LOG7[16355:3074153328]: Remote FD=14 initialized 2012.06.25 14:18:26 LOG7[16355:3074153328]: TCP_NODELAY option set on remote socket 2012.06.25 14:18:26 LOG7[16355:3074153328]: SSL state (connect): before/connect initialization 2012.06.25 14:18:26 LOG7[16355:3074153328]: SSL state (connect): SSLv2/v3 write client hello A 2012.06.25 14:18:26 LOG3[16355:3074153328]: SSL_connect: 140770FC: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol 2012.06.25 14:18:26 LOG5[16355:3074153328]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2012.06.25 14:18:26 LOG7[16355:3074153328]: nntp finished (0 left) Anyone know what is missing?

Interoperability problems with .net client software
by ProPharma Systems AG - Gregor Bürgisser 28 Jun '12

28 Jun '12

Hi all, I'm using stunnel 4.53 under Linux to secure a service. There are two different clients connecting to this service: My own client, also Linux based and using libcurl and another (third party!) client being developed using Microsoft .net stuff. Of course with my own client all works well. But we are not able to get the Microsoft client running. stunnel keeps on telling: SSL_accept: 140890C7: error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate We have tried diffierent things... I will outline them here if you think it is helpful (in short: tried using certificates generated on the Microsoft side, then tried using certificates created on the Linux side). If "verify" ist set to 0 or 1 it works (of course) but with a higher value the above message is logged. Are there any known pitfalls, problems or whatsoever when using stunnel with a .net client? Any advice would be appreciated! Regards, Gregor

Accept on same port to ethernet aliases
by John Morrison 27 Jun '12

27 Jun '12

Hi, Is it possible to configure stunnel to use the same port on different IP addresses that are Ethernet aliases? I have successfully set up a configuration file accepting SSL connections. Firstly I did this on all IP addresses by using the following configuration lines: accept = 443 connect = 80 This worked correctly. I then attempted to setup a second configuration file on an aliased Ethernet address. The configuration file settings are: test1.conf accept = 10.168.1.132:443 connect = 10.168.1.132:80 test2.conf accept = 10.168.1.133:443 connect = 10.168.1.133:80 Stunnel is able to start the first configuration file, but not the second. The error message I can see when I run the second configuration file in the foreground is: accept socket: FD=11 allocated (non-blocking mode) Option SO_REUSEADDR set on accept socket Error binding https to 10.168.1.133:443 bind: Address already in use (98) and if I telnet to 10.168.1.133 on port 443 the connection is accepted. I have attempted to use the binding socket options in the configuration files as described in the manual: socket = a:SO_BINDTODEVICE=eth0:0 and socket = a:SO_BINDTODEVICE=eth0:1 However in this case stunnel will not start either configuration file. The error message I receive is: Option SO_REUSEADDR set on accept socket SO_BINDTODEVICE: No such device (19) Is there a different way to configure stunnel to allow this to work? My ipconfig settings are below. I am running the ubuntu 10.04 version of stunnel. The version output is: stunnel 4.35 on x86_64-pc-linux-gnu with OpenSSL 1.0.0e 6 Sep 2011 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Thanks, John eth0:0 Link encap:Ethernet HWaddr 3c:4a:92:6d:0b:08 inet addr:10.168.1.132 Bcast:10.168.1.132 Mask:255.255.255.255 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 Memory:f4000000-f4012800 eth0:1 Link encap:Ethernet HWaddr 3c:4a:92:6d:0b:08 inet addr:10.168.1.133 Bcast:10.168.1.133 Mask:255.255.255.255 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 Memory:f4000000-f4012800

Confused about stunnel + haproxy
by Robin Lee Powell 27 Jun '12

27 Jun '12

I've set up stunnel + haproxy using the "protocol = proxy" method, but stunnel doesn't seem to pass to haproxy any information about the source IP of the original connection, which I thought was the point of using this method? Can someone tell me what I'm missng? I just want to have haproxy with SSL support without losing the client IP information completely. -Robin -- http://singinst.org/ : Our last, best hope for a fantastic future. .i ko na cpedu lo nu stidi vau loi jbopre .i danfu lu na go'i li'u .e lu go'i li'u .i ji'a go'i lu na'e go'i li'u .e lu go'i na'i li'u .e lu no'e go'i li'u .e lu to'e go'i li'u .e lu lo mamta be do cu sofybakni li'u

socket status
by Dee Ayy 20 Jun '12

20 Jun '12

My socket in Eiffel will report that it is connected, but when it tries to write to the socket, it will fail and report Connection reset by peer I/O error The syslog shows 1) ... accepted connection from 127.0.0.1:.. 2) connect_blocking: getsockopt A_REMOTE_IP:A_REMOTE_PORT: Connection refused (111) 3) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I believe that my socket is connecting locally fine 127.0.0.1:.. in step 1, and then the remote connection via stunnel is failing in step 2, but I have tried to write to the socket in between steps 1 and 2. Is this proper behavior? How can I know the status of the remote connection? Wait a while and then test? Is the socket state really just the state of the local stunnel connection? Should stunnel report a different state (as seen by my socket) until it determines the remote socket state?

stunnel version 4.53 says SSL server needs a certificate on Windows 7?
by Wayne Walter 13 Jun '12

13 Jun '12

I have been using stunnel previous versions just fine. It didn't apparently have the feature of a certificate in SSL server mode. That's alright but not necessary for us as we're simply running a localhost server to tunnel to the remote server. Anyway, I have read the FAQ tutorial and such related to this and tried everything. No mater what I do with the cert or key settings it still gives this same error here's the complete output.... No limit detected for the number of clients stunnel 4.53 on x86-pc-mingw32-gnu platform Compiled/running with OpenSSL 0.9.8s-fips 4 Jan 2012 Threading:WIN32 SSL:+ENGINE+OCSP+FIPS Auth:none Sockets:SELECT+IPv6 Reading configuration from file stunnel.conf FIPS mode is enabled Compression not enabled Snagged 64 random bytes from C:/.rnd Wrote 0 new random bytes to C:/.rnd PRNG seeded successfully Initializing service section [FIX] Section FIX: SSL server needs a certificate Server is down And here is the stunnel.conf file contents: ; Certificate/key is needed in server mode and optional in client mode cert = stunnel.pem ;key = stunnel.pem ; Disable support for insecure SSLv2 protocol options = NO_SSLv2 [FIX] accept = 127.0.0.1:5679 connect = 216.52.236.112:5680 TIMEOUTconnect = 5 [FIXLIVE] accept = 127.0.0.1:5680 connect = 216.52.236.185:51581 TIMEOUTconnect = 5 Please not that stunnel came installed with an stunnel.pem file. I tried uncommenting the config line for the key. Also regenerated the key using openssh per instructions. I tried using absolute path to the cert file. Nothing makes any difference. Is this a defect in stunnel? Or am I doing something wrong?

stunnel - haproxy setup with protocol = proxy
by Scott McKeown 07 Jun '12

07 Jun '12

Hi Robert, I've been doing some work on both HAProxy and STunnel myself over the last month or so. Your actual configuration files both look fine but one thing that you possibly missed is that you will have needed to have build HAProxy with the TProxy flag enabled, and I'm going to guess that you have also written and applied the Firewall rules for the transparent proxy. I've attached a DRAFT pdf of the work that I have been doing, its a very basic how-to on setting up both STunnel and HAProxy in Transparent mode on a Centos 6.2 system. -- With Kind Regards.

stunnel - haproxy setup with protocol = proxy
by Robert Garcia 07 Jun '12

07 Jun '12

I am trying to setup stunnel with protocol = proxy through haproxy to my apache2 cluster. I have been using haproxy for a while, and wanted to try this before having to go to nginx, or some other proxy. My config works fine as is if I remove the "accept proxy" from the haproxy.cfg and the protocol=proxy from stunnel config, as soon as those are in, I get a 502 bad gateway.

I'm using stunnel as a reverse proxy. I have an smtp server smtp1 and an stunnel server proxy1. Clients connect to and negotiate ssl on proxy1 which then connects to smtp1 via a plaintext connection. stunnel does not reside on the client. If I connect the client directly to smtp1 via ssl it works fine.

Outlook and stunnel
by James Devine 05 Jun '12

05 Jun '12

I am trying to setup stunnel to ssl proxy mail to an smtp server and this seems to work fine for thunderbird but when I try using outlook 2010 to connect via ssl I get the error: Send test e-mail message: Your server does not support the connection encryption type you have specified. Try changing the encryption method. For sslVersion I have the option of SSLv3 and TLSv1, all and SSLv2 do not seem to work so I'm not sure if that is the problem Anyone else run in to this or know what I might do to resolve it?

stunnel 4.53 released
by Michal Trojnara 03 Jun '12

03 Jun '12

Dear Users, I have released version 4.53 of stunnel. This is major a bugfix release. Upgrade is highly recommended. The ChangeLog entry: Version 4.53, 2012.03.19, urgency: MEDIUM: * New features - Added client-mode "sni" option to directly control the value of TLS Server Name Indication (RFC 3546) extension. - Added support for IP_FREEBIND socket option with a pached Linux kernel. - Glibc-specific dynamic allocation tuning was applied to help unused memory deallocation. - Non-blocking OCSP implementation. * Bugfixes - Compilation fixes for old versions of OpenSSL (tested against 0.9.6). - Usage of uninitialized variables fixed in exec+connect services. - Occasional logging subsystem crash with exec+connect services. - OpenBSD compilation fix (thx to Michele Orru'). - Session id context initialized with session name rather than a constant. - Fixed handling of a rare inetd mode use case, where either stdin or stdout is a socket, but not both of them at the same time. - Fixed missing OPENSSL_Applink http://www.openssl.org/support/faq.html#PROG2 - Fixed crash on termination with FORK threading model. - Fixed dead canary after configuration reload with open connections. - Fixed missing file descriptors passed to local mode processes. - Fixed required jmp_buf alignment on Itanium platform. - Removed creating /dev/zero in the chroot jail on Solaris platform. - Fixed detection of WSAECONNREFUSED Winsock error. - Missing Microsoft.VC90.CRT.manifest added to Windows installer. Home page: http://www.stunnel.org/ Download: ftp://ftp.stunnel.org/stunnel/ SHA-256 hash for stunnel-4.53.tar.gz: 3e640aa4c96861d10addba758b66e99e7c5aec8697764f2a59ca2268901b8e57 Best regards, Mike

Hi Mike, Thank you for your input. I'll rebuild today and retest. Our company openly supports Open Source projects that we use and we will continue to do so. However, since we are still in a R&D position with STunnel at the moment I thought it would be better to continue to use the users group. I'll post again once I've rebuilt and tested, which might not be until the end of next week now as we have an nice extended weekend in the UK for the Golden Jubilee which is nice. ~Yours, Scott -- With Kind Regards.

Hi Michal, Thanks for following this up. I'm using the latest build of STunnel v4.53 as shown below (I check the site once a week just to make sure too) # stunnel -version stunnel 4.53 on x86_64-unknown-linux-gnu platform Compiled/running with OpenSSL 1.0.0-fips 29 Mar 2010 Threading:PTHREAD SSL:+ENGINE+OCSP+FIPS Auth:none Sockets:POLL+IPv6 Global options: debug = daemon.notice pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options: ciphers = FIPS (with "fips = yes") ciphers = ALL:!SSLv2:!aNULL:!EXP:!LOW:-MEDIUM:RC4:+HIGH (with "fips = no") session = 300 seconds sslVersion = TLSv1 (with "fips = yes") sslVersion = TLSv1 for client, all for server (with "fips = no") stack = 65536 bytes TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none I've also included a copy of my stunnel.cfg file below: # more /etc/stunnel/stunnel.cfg # STunnel configuration file generated by loadbalancer.org appliance setgid = nobody pid = /stunnel.pid debug = 0 [S1] accept = 192.168.82.182:443 connect = 192.168.82.181:81 cert = /etc/loadbalancer.org/certs/S1.pem ciphers = RC4:HIGH:!MD5:!aNULL options = NO_SSLv2 protocol = proxy I'm looking to include the STunnel Product within our Loadbalancer Appliance in our next upcoming release but with everyone now using the SSL checker that I mentioned in one of my last e-Mails more customers are becoming concerned about MITM Attacks etc. so I would really like to get this solved before I move forward with the project. Oh, I guess I should also mention that this is running on a Centos 6.2 box. ~Yours, Scott

BEAST Attack
by Scott McKeown 29 May '12

29 May '12

Hi All, Has anyone looked at the current issue with the BEAST Attack. I'm looking at https://www.ssllabs.com/ssltest/index.html which can be used for testing SSL Certificates I also use Pound Proxy which I have now patched and this has removed the threat. However, I don't seem to be able to get the same result from a STunnel installation. If anyone can give some advice that would be great. ~Yours, Scott

limit to number of services
by Terren Suydam 25 May '12

25 May '12

Hi there, I seem to be hitting a limit on the number of stunnel services I can run simultaneously. According to the log, they appear to set up without any issues, but after 64 services they don't pass traffic. Is this something stunnel itself limits, or is it an OS limitation? I am running the latest windows build on Windows Server 2008. Either way, is there an easy way to increase the number of services? Thanks, Terren

Stunnel quitted unexpectedly repeated for a number of times

Hi all, We have encountered a strange situation that stunnel We have the following setup in our production servers. > Windows [ ... -> Apache -> Stunnel 4.50 ] --> AIX [Stunnel 4.50 -> JBoss] * As we had experienced the Stunnel in AIX died in a random time during testing stage, we added a cron job to start Stunnel in case stunnel disappeared. Recently, in our production servers, the stunnel disappeared and being started by corn repeatedly during a short period of time in the same day. We so far encounter similar problem for 2 times. Below are the restart time of the most recent incident. > 09:22:00,09:38:00,09:45:00, > 10:24:00,10:34:00,10:50:00, > 11:06:00,11:16:01,11:17:00,11:19:00,11:22:00,11:23:00,11:29:01,11:32:00,11:34:01,11:35:00,11:39:01 We found that in the logs, they always ended with the following: > 2012.05.23 11:16:03 LOG7[12517524:1]: Dispatching signals from the signal pipe > ... > 2012.05.23 11:16:03 LOG7[12517524:1]: Processing SIGCHLD > ...(same message repeatly for serveral time) > 2012.05.23 11:16:03 LOG7[12517524:1]: Processing SIGCHLD Here is the active options in config file: [Windows Side] > debug = 7 > output = D:\app-logs\stunnel\stunnel.log > verify = 0 > options = NO_SSLv2 > client = yes > taskbar = no > [prdweb01_out_app01] > accept = PRDWEB01:18009 > connect = PRDAPP01:18010 > [prdweb01_out_app02] > accept = PRDWEB01:18019 > connect = PRDAPP02:18010 [AIX Side] > pid = /opt/stunnel/4.50/prd/stunnel0-app/stunnel.pid > debug = 7 > output = /opt/stunnel/4.50/prd/stunnel0-app/log/stunnel.log > cert = /opt/stunnel/4.50/prd/stunnel0-app/PRD.certnew-b64.cer > key = /opt/stunnel/4.50/prd/stunnel0-app/PRD.private.key > options = NO_SSLv2 > [prdweb_in] > accept = PRDAPP01:18010 > connect = PRDAPP01:8009 Start up command > nohup stunnel /opt/stunnel/4.50/prd/stunnel0-app/stunnel-server.conf Attached at the end is the one of the log during the incident. Is there any suggestion on how to find out the cause of the problem? What are the possible causes that would make it disappeared after those processing of SIGCHLD signal?

First message flows through second one does not
by George Cardenas 19 May '12

19 May '12

I been chasing my tail a few days now reading through every post and searching in the internet how to work around this issue. The first message will flow though but any other messages after that wont. The log doesn't tell me anything besides that the first attempt sent more bytes than the second attempt.

Compiling stunnel without a cert
by Donovan Sydow 08 May '12

08 May '12

I'm trying to automate the compilation of stunnel from source and was curious if there was a hidden flag to prevent stunnel from trying to generate a certificate after running make install. I do know I can make a file called stunnel.pem in the system configuration directory prior to running make install to prevent the cert from being made, but ideally wanted a way to have stunnel install without having a cert pregenerated. I didn't see any configure flags to prevent this behavior. Does any one know how to bypass this requirement and compile without generating a certificate or having one already exist? Alternately I would be interested in hearing any suggestions on how to quietly generate the initial certificate as well in an automated (i.e. no input, quiet, etc.) fashion. Cheers, Donovan

Getting Stunnel to Work Under Windows 7 64-bit
by Thomas Eifert 03 May '12

03 May '12

For the benefit of the group, I thought I'd share some experiences I had when attempting to get Stunnel to run under Windows 7 SP1 64-bit. I initially installed Stunnel version 4.53 to the default location, which in Windows 7 64-bit is: C:\Program Files (x86)\stunnel\ I installed the service from the start menu option, then rebooted my machine. I have administrator rights, and User Account Control is disabled. My observations included the following: 1. The Stunnel status window displayed only configuration loads. No output from any active connection was ever displayed, despite the fact that Stunnel was passing traffic to/from SSL-enabled servers. 2. Stunnel would not write to the log file. The error message indicated that Stunnel was unable to open stunnel.log. Initially, I thought this might be a factor in the lack of status window connection output, so I commented the log statement out to eliminate it. I then reloaded the configuration. The issue of not seeing any connection info was unaffected. 3. The notification area icon would not appear on Stunnel service load. It would mysteriously appear, then disappear, at seemingly random times. 4. Once the service was installed, it was not possible to stop it or uninstall it from the provided start menu shortcuts. Whenever I attempted to do so, the Stunnel status window would appear. However, I was able to perform these actions successfully by opening a command prompt, then issuing the commands from there. In an effort to unravel these issues, I tried the following workarounds: 1. I re-installed stunnel to a non-system controlled directory. In my case, it was C:\Apps\stunnel\. 2. I attempted to run stunnel in compatibility mode, set for Windows XP SP3. 3. I tried installing 2 previous versions of Stunnel. All combinations produced exactly the same undesired result. Finally, I stopped and uninstalled the service. Instead of using that method, I created a shortcut to stunnel.exe, and placed it in the start menu's startup folder, then rebooted. Stunnel started at boot time, and all of the above issues were resolved. As such, it seems like Stunnel just doesn't like to be run as a service on a Windows 7 64-bit machine; at least not on the one I own. If you're encountering any stability issues with the Stunnel service in the Windows 7 64-bit environment, try my method. It works. I'd like to extend a special thank you to Carter Browne, who provided valuable input throughout the course of my testing.

Hi all, I'm pretty new to stunnel but did get this config to work on a linux box - now I am trying the same/similiar config on a win7 box but keep getting the handshake error below. I am using the latest version of stunnel and have tried searching for an answer via google, making the proposed changes as described No matter what settings I use it always seems to use the sslv3 handshake which then goes wrong :-( I'd appreciate any help on this Colin My config is as follows: ; ************************************************************************** ; * Global options * ; ************************************************************************** ; Debugging stuff (may useful for troubleshooting) ; Some debugging stuff useful for troubleshooting debug = 7 output = c:\temp\stunnel.log ; Use it for client mode client = yes rndbytes = 256 rndfile = c:\temp\randseed.bin ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Disable FIPS mode to allow non-approved protocols and algorithms fips = no ; ************************************************************************** ; * Service defaults may also be specified in individual service sections * ; ************************************************************************** ; Certificate/key is needed in server mode and optional in client mode cert = CT_20110324.pem ; Disable support for insecure SSLv2 protocol sslVersion = TLSv1 options = NO_SSLv2 options = NO_SSLv3 [CT] ; incoming connection from the client application accept = 444 ; outgoing connection connect = remote.server.com:443 TIMEOUTclose = 0 Error in log file 2012.04.11 18:33:54 LOG7[3684:3640]: Remote socket (FD=440) initialized 2012.04.11 18:33:54 LOG3[3684:3640]: SSL_connect: 14094410: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure 2012.04.11 18:33:54 LOG5[3684:3640]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2012.04.11 18:33:54 LOG7[3684:3640]: Remote socket (FD=440) closed 2012.04.11 18:33:54 LOG7[3684:3640]: Local socket (FD=408) closed 2012.04.11 18:33:54 LOG7[3684:3640]: Service [CT] finished (0 left)

Using Stunnel client but not Stunnel server with Apache mod_ssl
by Lilienberg, Daniel () 27 Apr '12

27 Apr '12

Hi, My supplier is using a somewhat strange setup looking like this: CLIENT: Stunnel running in client mode accepting incoming requests on port 8080. It will forward it to port to a server, port 443. SERVER: NOT running Stunnel at all, but running Apache with mod_ssl. It also acts as a proxy server, proxying all requests. Can this work, if so, how do I set it up ?

Hello With verify=3 and the certs loaded in the conf file with CAfile=startssl-chain.pem cert=mycert.pem, I get : CERT: Certificate not found in local repository Using the latest stunnel recompiled on a debian squeeze, the best I can get is: error queue: 140B0009: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib SSL_CTX_use_PrivateKey_file: 906D06C: error:0906D06C:PEM routines:PEM_read_bio:no start line However, if I put these very same pem files in a directory as a CApath option instead (c_rehash applied) everything works fine. But The pem files are identical ! I've read http://stunnel.mirt.net/pipermail/stunnel-users/2010-November/002854.html but it seems a bit different The startssl-chain.pem was created with: wget http://www.startssl.com/certs/ca.pem wget http://www.startssl.com/certs/startssl.ca.pem cat sub.class1.server.ca.pem ca.pem > startssl-chain.pem I guess that may be the cause of the problem? What should I do to pass these pem files as stunnel.conf options instead of using the CApath? Guylhem

Stunnel compiled with openssl 1.0.1 local binaries are 0.9.8k
by Michael Curran 11 Apr '12

11 Apr '12

Are there any potential known issues with stunnel being compiled using openssl 1.0.1 build and leaving the local system binaries at 0.9.8k Do you know of any way to test this for any incompatibilities? This was not my design, Im just being asked to support it and Im looking to make sure this method is not going to cause anything unusual.

PPID of child process

Hi, I’m trying to setup stunnel listening to multiple ports. The PPID of processes created are always root. Can we change that to the right PPID? Here I can see all the processes by killing 10764 and I expect this is the PPID. But all the children PPID are still 1; UID PID PPID C STIME TTY TIME CMD philwong 10759 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10760 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10761 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10762 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10763 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10764 1 0 16:27 ? 00:00:00 stunnel self.conf Regards, Philip

the connection had to be retried using SSL 3.0. This typically means that the server is using very old software and may have other security issues :(
by Thomas Manson 10 Apr '12

Hi, while I'm trying to get stunnel working for more than a few hours, I've also notice this warning in google chrome : the connection had to be retried using SSL 3.0. This typically means that > the server is using very old software and may have other security issues. [image: Inline image 1] gmail for example has AES_128_CBC for crypting, can we get that without much effort? What should be set to get rid of this warning ? I thought SSL v3 was the best (quickly pick acrross several example on the net) what is the best setting for this ? Thanks for your help, Thomas. My config : debug = 7 output = /var/log/stunnel4/extranet.service.com_stunnel.log setuid = stunnel4 setgid = stunnel4 pid = /var/run/stunnel4/extranet.service.com.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [extranet.service.com] key = /etc/stunnel/sites/extranet.service.com/extranet.service.com.key cert = /etc/stunnel/sites/extranet.service.com/extranet.service.com.crt accept = 8.90.17.4:443 connect = 127.0.0.1:82 sslVersion = SSLv3 TIMEOUTclose = 0

[Stunnel Guru needed] stunnel running, but no longer serve connection after a while ("Dispatching signals from the signal pipe" in logs ==> all stops)
by Thomas Manson 09 Apr '12

09 Apr '12

Hi All, I'm really struggling to make stunnel working for more than a few hours. (and the client is yelling hard...) (I solved some other issue : logging per website and making more than one stunnel works) To put it in a nutshell : - stunnel is running and working correctly (I can reach the website in https correctly) - after some hours I get the following situation : - stunnel is still running on linux - trying to connect to a website result in the connection taking very long time and then fails : "*The connection to * extranet.serviceplus-hse.com <http://extranet.website.com>* was interrupted. Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.*" (Chrome) Same symptoms on IE9, Firefox & Lynx (on the server that runs stunnel) (see logs below) - The following logs are the last one seen in the log file : - 2012.04.03 23:33:28 LOG5[24792:140152610346752]: Service extranet.serviceplus-hse.com connected remote server from 127.0.0.1:36256 - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Remote FD=1 initialized - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Option TCP_NODELAY set on remote socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Socket closed on read - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Sending SSL write shutdown - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: SSL alert (write): warning: close notify - 2012.04.03 23:33:41 LOG6[24792:140152610346752]: SSL_shutdown successfully sent close_notify - 2012.04.03 23:33:41 LOG3[24792:140152610346752]: transfer: s_poll_wait: TIMEOUTclose exceeded: closing - 2012.04.03 23:33:41 LOG5[24792:140152610346752]: Connection closed: 186584 bytes sent to SSL, 3275 bytes sent to socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Service extranet.serviceplus-hse.com finished (0 left) - 2012.04.04 06:25:04 LOG7[24792:140152610629408]: *Dispatching signals from the signal pipe * stopping the firewall & fail2ban do not change anything.

Hi, To get around a bug of stunnel present in the package of Ubuntu 11.10 (that has been corrected in v4.38), I've compiled from sources (v4.53). It went well, but I did notice a change in the processes : from compiled sources, I can see only on process per conf file ###################################################################### 1 21402 21402 21402 ? -1 Ss 109 0:00 /usr/local/bin/stunnel4 /etc/stunnel/base.conf 1 21411 21411 21411 ? -1 Ss 109 0:00 /usr/local/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 21420 21420 21420 ? -1 Ss 109 0:00 /usr/local/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf ###################################################################### while on the ubuntu version, I've multiple process per conf file. ps -edf from ubuntu distrib ###################################################################### 1 24773 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24774 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24775 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24776 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24777 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24778 24778 24778 ? -1 Ss 109 0:00 /usr/bin/stunnel4 /etc/stunnel/base.conf 1 24787 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24788 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24789 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24790 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24791 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24792 24792 24792 ? -1 Ss 109 0:00 /usr/bin/stunnel4 /etc/stunnel/extranet.serviceplus-hse.com.conf 1 24801 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf 1 24802 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf 1 24803 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf 1 24804 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf 1 24805 24762 18168 ? -1 S 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf 1 24806 24806 24806 ? -1 Ss 109 0:00 /usr/bin/stunnel4 /etc/stunnel/mansonthomas.com.conf ###################################################################### I'm using the exact same version of conf file for both setup... any idea why this change ? is one better than another ?

Transparent STunnel & HAProxy on Centos6.2
by Scott McKeown 07 Apr '12

07 Apr '12

Hi All, I've been playing with this for a little while now and before the all in front of me and my head meet I was wondering if someone else could shed some light on this for me please. First off let me give you a over view of the network setup: My Virtual Machine has two interfaces eth0 has two addresses 192.168.82.9/18and 192.168.82.10/18. 192.168.82.9 is going to be for the management of the server and 192.168.82.10 is what the website will respond too. eth1 has a network of its own 10.0.0.0/24 and I have two Debian Apache web servers that are connected to this network 10.0.0.10 and 10.0.0.20. If this was a real world setup I might have put the management address (192.168.82.9) on a different port but I didn't think of that at the time of setting this up but I may do that later. Second what have I done! Well this is a brand new install of Centos6.2 minimal fully patched and both HAProxy and STunnel downloaded and installed. I'm using the devel version of HAProxy but thats a different story and version 4.53 of STunnel. Now the problem. Both seem to work perfectly as-long as I don't want to know who is accessing my site which make it next to useless. However, I can get HAProxy to report the IP Address of the visitor as long as you visit the HTTP page on port 80 as per my configuration file. I can also get STunnel to work with HAProxy but as soon as I enable 'protocol = proxy' the HTTPS side breaks and all I get in my browser is '400 Bad Request Your browser sent an invalid request'. I've played with everything I can thing of and I still cant get a Transparent STunnel>HAProxy solution working correctly. Config Files: stunnel.conf ====================================== chroot = /usr/local/var/lib/stunnel/ #setuid = nobody setgid = nobody pid = /stunnel.pid cert = /usr/local/etc/stunnel/stunnel.pem key = /usr/local/etc/stunnel/stunnel.pem options = NO_SSLv2 debug = 7 #fips = no [https] accept = 192.168.82.10:443 connect = 192.168.82.10:80 protocol = proxy haproxy.cfg ====================================== global daemon log /dev/log local4 maxconn 40000 ulimit-n 81000 defaults log global mode http contimeout 4000 clitimeout 42000 srvtimeout 43000 listen http1 bind 192.168.82.10:80 mode http option http-server-close option forwardfor source 0.0.0.0 usesrc clientip balance roundrobin server http1_1 10.0.0.10:80 cookie http1_1 check inter 2000 rise 2 fall 3 server http1_1 10.0.0.20:80 cookie http1_1 check inter 2000 rise 2 fall 3 Log file ====================================== Apr 5 12:37:32 lbmaster haproxy[1351]: Proxy http1 started.

MySQL through stunnel - fails after many days
by Whit Blauvelt 04 Apr '12

04 Apr '12

Hi, I have a Nagios plugin using an stunnel connection to a MySQL server across the LAN for frequent queries, where each one opens a fresh connection. Checking ulimit on both ends shows "unlimited" (I've found old discussions about that being a possible factor). There's nothing I've found in the logs to show where it's going wrong. It's just that after days of running fine, suddenly the queries start failing to connect through. Restarting stunnel on both ends immediately resolves the problem. I suppose I can just restart stunnel on both ends once a day from cron and be okay. But I'd rather find a real fix, if anyone recognizes what this would be and can point me to one. Thanks, Whit

Dear Users, Hi In our network users connect to internet using http proxy. I have a configuration file like this: [proxy] accept:4444 connect:remote_ip:remote_port connecting to remote ip needs http proxy. I tested some configurations like this: [proxy] protocol = connect protocolHost = proxy_ip:proxy_port accept:4444 connect:remote_ip:remote_port or [proxy] protocol = proxy protocolHost = proxy_ip:proxy_port accept:4444 connect:remote_ip:remote_port But now no success!!! How can i set stunnel to use proxy? Regards, Ebrahim khalilzadeh --

Stunnel running for a few minutes and then stop and can't handle multiple domains
by Thomas Manson 01 Apr '12

01 Apr '12

Hi, I've setup a stunnel install to handle several website SSL part of the HTTP (then redirected to HAProxy LoadBalancer). I can successfully start one site, but if I add another website (so another stunnel conf file in /etc/stunnel) then the first is said to be already running while it's not and the second starts for real. thomas@ns0:/var/log/stunnel4$ sudo service stunnel4 start Starting SSL tunnels: [Started: /etc/stunnel/base.conf] [Started: /etc/stunnel/extranet.onesite.com.conf] *[Already running: /etc/stunnel/mansonthomas.com.conf] stunnel.* (mansonthomas.com was my first try before implementing a client website) Also, in /var/log/stunnel.log I've only the logs for base.conf, not for the two other one. What should I do to have the logs? I've tryed to add debug=7 at the beginning of the two conf file, but nothing. After some times, the extranet site https stops working... I was off in holidays for the last two weeks, so I didn't have the time to really dig into this... what would be the first steps to debug this issues ?

Looking for help - Stunnel works with Gmail but not with my provider
by Verberne, Pieter 31 Mar '12

Hello, I have successfully used stunnel with blat to send e-mails from my gmail accounts. Getting this to work with my new internet provider "Ziggo" in The Netherlands seems impossible, despite days spent on the internet searching for help and trying numerous configurations. Whatever I do, there is always this message: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number Any help would be highly appreciated. Pieter Verberne PC: i7 OS: Windows 7 - 64bits Stunnel version: 4.53 When sending an e-mail from my PC with Thunderbird 2.0 I can successfully use TLS but not SSL.

Hi Guys, Just tried to install stunnel-4.53 onto a virgin Cento6.2 x64 system with HAProxy (box is fully patched too), However, every time I runt the 'make' command I get the following output. I've had a bit of a hunt around but this is a little outside of both my comfort zone and my knowledge levels so any help would be great.

SNI with protocol=proxy ?
by Marek Majkowski 29 Mar '12

29 Mar '12

Hi, I'm having trouble using SNI with protocol=proxy. Stunnel seems to ignore protocol option defined in the 'children', for example now protocol will be ignored: [https_default] accept = 443 connect = 10443 cert = a.crt key = a.key [https_one] sni = https_default:one.org protocol = proxy connect = 10444 cert = one.crt key = one.key On the other hand when defined on the 'default' resource, the connect option seems to be ignored: [https_default] accept = 443 protocol = proxy connect = 10443 cert = a.crt key = a.key [https_one] sni = https_default:one.org connect = 10444 ;; nope! still 10443 cert = one.crt key = one.key Any suggestions? Cheers, Marek

RMI with SSL
by Anoop Joseph 29 Mar '12

29 Mar '12

Hi, We have an existing RMI server which is not SSL aware and is based on Java version 1.4.1. We want to use stunnel to make this existing RMI server SSL aware. Checking the official website of stunnel the support to following protocols were found cifs , connect, imap, nntp, pgsql, pop3, proxy and smtp. As no reference to JRMP was available, wondering if stunnel can be used to make the existing non SSL RMI server SSL aware. If this is possible then we belive that it would be achived by providing the mapping between the port configured with stunel and the existing port used by RMI. Also the eixsitng RMI server would have to undergo minial change using this approach. Your help is highly appreciated. Thanks in advance. Best Regards, Anoop

Thomas, After a few exchanges a few hours ago with the folk at STunnel I can confirm that the "problem" was that the company uses host headers. Here is the procedure I used to sort it out: 1. Modify the windows host file and add the following entry 127.0.0.1 rest.nexmo.com. If your STunnel ir running on a different machines, set the 127.0.0.1 to the IP address of the Stunnel server. 2. Add the following to the stunnel.conf file (you may alter the port) [nexmo] client = yes accept = 9013 connect = 174.120.166.82:443 TIMEOUTclose = 0 3. Start sending secure SMSs as follows (note the port number much match the one set in stunnel.conf) http://rest.nexmo.com:9013/sms/xml?username=xxxxxxx&password=xxxxxxx&from=xx xxxxxx&to=xxxxxxx&text=xxxxxxx This will bypass the issue related to host headers and I can confirm that the solution has worked. The setup is useful if using server technology that does not natively support SSL as is our case. Hope this helps. Alan ---------------------------------------------------------------------------- ---------------------------------------- Alan; While I don't generally use Stunnel for HTTPS, I found your question interesting. Since I'm always trying to experiment with configurations of and applications for Stunnel, I decided to give it a whirl. I'm happy to confirm that it works just fine for me. I'm not connecting to the site in your example, but the principle is the same. Perhaps the answer lies in how your browser parses that URL, and how, as a result, it inserts that data into the stream. For the experiment, I used Firefox 9.0.1 running under Windows XP x86 with Stunnel version 4.53. My test config was: debug = 6 fips = no delay = yes output = stunnel.log [https] client = yes accept = 127.0.1.21:7777 connect = www.host.domain:443 Where www.host.domain is just an example. As you can see, I did not include any TIMEOUTclose statement in my config file. Then I pointed the browser at http://127.0.1.21:7777/do/mypage/longparameterstringhere. As far as I can tell, all of the parameters contained in that string were passed on to the web site without any difficulty. You might want to check your log window to see what's happening when you try to connect via Stunnel. Here's an actual example of the connection activity from my log: 2012.03.22 21:20:51 LOG5[992:2548]: Service [https] accepted connection from ***.**.***.*:2671 2012.03.22 21:20:51 LOG6[992:2548]: connect_blocking: connecting ***.***.***.***:443 2012.03.22 21:20:51 LOG5[992:2548]: connect_blocking: connected ***.***.***.***:443 2012.03.22 21:20:51 LOG5[992:2548]: Service [https] connected remote server from ***.**.***.*:2672 2012.03.22 21:20:51 LOG6[992:2548]: SSL connected: new session negotiated 2012.03.22 21:20:51 LOG6[992:2548]: Negotiated TLSv1/SSLv3 ciphersuite: RC4-SHA (128-bit encryption) 2012.03.22 21:20:51 LOG6[992:2548]: Compression: null, expansion: null 2012.03.22 21:21:00 LOG6[992:2548]: SSL_shutdown successfully sent close_notify alert 2012.03.22 21:21:00 LOG5[992:2548]: Connection closed: 1879 byte(s) sent to SSL, 128546 byte(s) sent to socket If you have to post again, it would be helpful if you included more detail.

Hi, I am new to STunnel. I am trying to connect to a service provided by nexmo.com. If from a browser I type the following: https://rest.nexmo.com/sms/xml?username=xxxxxxx <https://rest.nexmo.com/sms/xml?username=xxxxxxx&password=xxxxx&from=xxxxxxx &to=xxxxxxx&text=xxxxxxxxxx> &password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx The process works. I just installed stunnel and have the following config file ; Debugging stuff (may useful for troubleshooting) ;debug = 7 ;output = stunnel.log ; Certificate/key is needed in server mode and optional in client mode cert = stunnel.pem ;key = stunnel.pem ; Disable support for insecure SSLv2 protocol options = NO_SSLv2 [nexmo] client = yes accept = 9012 connect = rest.nexmo.com:443 TIMEOUTclose = 0 When I type http://127.0.0.1:9012/sms/xml? username=xxxxxxx&password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx it does not. Can anyone please confirm whether what I am trying to do is doable and maybe highlight what I am doing wrong. Regards, Alan

I am trying to connect to a service provided by nexmo.com. If from a browser I type the following: https://rest.nexmo.com/sms/xml?username=xxxxxxx <https://rest.nexmo.com/sms/xml?username=xxxxxxx&password=xxxxx&from=xxxxxxx &to=xxxxxxx&text=xxxxxxxxxx> &password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx The process works. I just installed stunnel and have the following config file ; Debugging stuff (may useful for troubleshooting) ;debug = 7 ;output = stunnel.log ; Certificate/key is needed in server mode and optional in client mode cert = stunnel.pem ;key = stunnel.pem ; Disable support for insecure SSLv2 protocol options = NO_SSLv2 [nexmo] client = yes accept = 9012 connect = rest.nexmo.com:443 TIMEOUTclose = 0 When I type http://127.0.0.1:9012/sms/xml? username=xxxxxxx&password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx it does not. Can anyone please confirm whether what I am trying to do is doable and maybe highlight what I am doing wrong. Regards, Alan

Intermittent connection resets
by Jordan K 22 Mar '12

22 Mar '12

Hi, I've spent the better part of the day trying to find answers on this, and haven't had much luck. I have two systems that talk to eachother via stunnel. In the last week or so, I have noticed a number of errors in the application using the tunnel (messaging application), requiring multiple re-sends, etc. This is my setup. Both server and client run CentOS 6.2, with the RPM version of stunnel. Though it isn't the latest version, I believe RedHat do release any critical bugs in their updated RPMs. I did also go through the ChangeLog but couldn't find anything implemented since 4.29 that seemed to deal with what I'm seeing. stunnel 4.29 on x86_64-unknown-linux-gnu with OpenSSL 1.0.0-fips 29 Mar 2010 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!aNULL:!eNULL:!SSLv2 key = /etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none Socket option defaults: Option Accept Local Remote OS default SO_DEBUG -- -- -- 0 SO_DONTROUTE -- -- -- 0 SO_KEEPALIVE -- -- -- 0 SO_LINGER -- -- -- 0:0 SO_OOBINLINE -- -- -- 0 SO_RCVBUF -- -- -- 87380 SO_SNDBUF -- -- -- 16384 SO_RCVLOWAT -- -- -- 1 SO_SNDLOWAT -- -- -- 1 SO_RCVTIMEO -- -- -- 0:0 SO_SNDTIMEO -- -- -- 0:0 SO_REUSEADDR 1 -- -- 0 SO_BINDTODEVICE -- -- -- -- TCP_KEEPCNT -- -- -- 9 TCP_KEEPIDLE -- -- -- 7200 TCP_KEEPINTVL -- -- -- 75 IP_TOS -- -- -- 0 IP_TTL -- -- -- 64 TCP_NODELAY -- -- -- 0 Common config (basically default file released by RedHat, with certs and ports configured) : ---------------- ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = SSLv3 ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/run/stunnel/ setuid = stunnel setgid = stunnel ; PID is created inside the chroot jail pid = /stunnel.pid ; Some debugging stuff useful for troubleshooting debug = 7 output = /var/log/stunnel.log ------------------- When the connection breaks, the logs (debug=7) on both sides are: Client: 2012.03.21 19:58:14 LOG7[30685:140185543952128]: SSL state (connect): before/connect initialization 2012.03.21 19:58:14 LOG7[30685:140185543952128]: SSL state (connect): SSLv3 write client hello A 2012.03.21 19:58:14 LOG3[30685:140185543952128]: SSL_connect: Peer suddenly disconnected 2012.03.21 19:58:14 LOG5[30685:140185543952128]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket Server: 2012.03.21 19:58:14 LOG3[22230:140462283343616]: SSL_accept: Peer suddenly disconnected 2012.03.21 19:58:14 LOG5[22230:140462283343616]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket As I mentioned, it happens intermittently, with probably 50% of the connections working just fine, and the rest being disconnected. It ALWAYS seems to happen just after the client 'write client hello A', as opposed to later in the SSL handshake. I ran a tcpdump on both sides, it is below. Note that both the client and the server are NATd behind firewalls, on the server the port stunnel listens on (31112) is opened through the firewall.

Neither side originates any RST packets. When the connection is successful, the tcpdump looks a lot more normal, with an appropriate FIN exchange closing the session once the data has been sent. My questions are - am I missing something obvious? Am I correct in reading the above as some firewall or router between the two servers breaking the TCP connection by sending TCP RSTs to both endpoints? any help is appreciated. jordan

running stunnel from inetd
by Guylhem 21 Mar '12

21 Mar '12

Hello To follow up on my test, I would like to try and run stunnel from inetd However I wonder if anyone has an experience, suggestions, and some inetd.conf examples. I read it was possible in the FAQ but I didn't see a lot of examples Should I use a configuration file (for the global parameters) then specify connect= params? ex : 443 stream tcp6 nowait nobody /sbin/stunnel /etc/stunnel.conf connect=127.0.0.1:80 TIMEOUTclose=0 Thanks Guylhem

Hello I've read that EDH calculations were ca cause of significant slow up on http://matt.io/technobabble/hivemind_devops_alert:_nginx_does_not_suck_at_s… I'm running stunnel on a embedded Linux/MIPS, where I'm trying to light up the load. Is it possible to disable EDH? If so, how? I couldn't find any info on that. Thanks Guylhem

Hello, I use Stunnel with Windows. The configuration file "stunnel.conf" and the log file "stunnel.log" are in the %USERAPPDATA%\Stunnel folder. Stunnel starts and works without problems. But the GUI options "Edit stunnel.conf" and "Reload stunnel.conf" do not work. Is remedy possible? Sebastian

I have found the stunnel version on PCB : stunnel 4.35 on x86_64-pc-linux-gnu with OpenSSL 1.0.0e 6 Sep 2011 the version on PCA is 4.52 this is perhaps a too big difference isn't it ? Best Philippe

Re: [stunnel-users] issue with running stunnel
by Thomas Eifert 18 Mar '12

Hi again Dewen; It sounds to me like Stunnel isn't being accessed at all. You should be seeing something in the Stunnel log window. I run Stunnel under Windows, so what I generally do is get Stunnel to listen to the loopback interface at address 127.0.0.1, or some other address within the loopback interface range. As such, if I was attempting to access it with a utility like Netcat, my basic stunnel.conf would look something like this for the client side: debug =7 [service.name] client = yes accept = 127.0.0.1:12035 connect = destination.address:1230 Then, I would point Netcat to the listening address and port. In your case, that might be netcat 127.0.0.1:12035. Then see if Stunnel logs your connection attempt. Again, this is under Windows, so your mileage may vary. Let us know how it works out for you.

Stunnel 1.45 on Win7 x64, OCSP blows up
by Michael Olson 16 Mar '12

16 Mar '12

I'm using stunnel in client mode on a Windows 7 x64 workstation, installed using ftp://ftp.stunnel.org/stunnel/stunnel-4.52-installer.exe Everything works until I try to check the server certificate for revocation using an OCSP server, at which point stunnel crashes whenever I make a connection. The following error pops up in a dialog box: OPENSSL_Uplink(0FBE5000,14): no OPENSSL_Applink My config is pretty simple: -------------------------------------------------------------- debug = 7 # I do want FIPS enabled, but I figured one problem at a time. fips = no CAfile = ca-bundle.crt verify = 2 OCSP = http://ocsp.test.net/ options = NO_SSLv2 [test1] client = yes accept = 127.0.0.1:80 connect = web.test.net:443 -------------------------------------------------------------- The log gets as far as: 2012.03.02 11:07:41 LOG7[4296:5008]: OCSP: server connected when it crashes. -- Mike

Hi guys, Right now I am working on this issue trying to encrypt the communication between terminals and our back of house computer. I am trying to solve this problem with stunnel. If the terminal is 'smart' like computer, it will be no issue. implement the stunnel on both end. But it come to be a problem there is some dumb terminal, No way to set up stunnel in its side. I not sure stunnel can works here any more. if not, is there any other methods that may work? -- *Dewen Kong*

Stunnel->Stunnel Failure Behavior...
by Matt Wise 13 Mar '12

13 Mar '12

I'm using Stunnel in our environment to tunnel our ZooKeeper connections... it works reasonably well as long as ZooKeeper is running on our ZooKeeper servers properly. Here's an example of our server and client configs: Server: > cert = /etc/stunnel/zookeeper.pem > key = /etc/stunnel/zookeeper.key > CAfile = /etc/stunnel/zookeeper_ca.pem > verify = 2 > sslVersion = TLSv1 > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/zookeeper.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = 2 > debug = 4 > [zookeeper] > accept = 0.0.0.0:2182 > failover = rr > connect = 127.0.0.1:2181 Client: > cert = /etc/stunnel/zookeeper.pem > key = /etc/stunnel/zookeeper.key > CAfile = /etc/stunnel/zookeeper_ca.pem > verify = 2 > sslVersion = TLSv1 > client = yes > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/zookeeper.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = 2 > debug = 4 > [zookeeper] > accept = 127.0.0.1:2182 > failover = rr > connect = zookeeper1:2182 > connect = zookeeper2:2182 > connect = zookeeper3:2182 Now the intended behavior is that if 'zookeeper1', 'zookeeper'2, or 'zookeeper3' go down that the client will re-establish a connection with one of the other servers. However, that doesnt seem to be happening. Instead, when the connection dies, Stunnel seems to go into a massive loop trying to re-connect to the original server. > Feb 22 21:41:24 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) Whats missing in my config to make the failover work properly? —Matt

How to get stunnel to listen on an IPv6 interface?
by jshardlo 11 Mar '12

11 Mar '12

Hi - my server was recently connected to IPv6 as well as the original IPv4 network. I have been using stunnel for some time on the IPv4 network but now that I have IPv6 access I can't work out how to get stunnel to listen on that interface as well. I checked that my stunnel has IPv6 support:- /usr/sbin/stunnel -version stunnel 4.15 on i686-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /etc/stunnel/stunnel.pem session = 300 seconds TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none I have a configuration like this: [pop3s] accept = 995 connect = 110 But when I do netstat I can see that it is only listening for port 995 on IPv4... netstat -an | grep 995 tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN netstat -an -A inet6 | grep 995 And of course when I connect to port 995 over the IPv6 network I get "connection refused". Any ideas how to get stunnel to listen on the v6 address? Thanks ! -- View this message in context: http://old.nabble.com/How-to-get-stunnel-to-listen-on-an-IPv6-interface--tp… Sent from the Stunnel - Users mailing list archive at Nabble.com.

Stunnel.conf won't load with certain ciphers.
by Thomas Eifert 09 Mar '12

Hello all: I'm running Stunnel 4.52 under WinXP SP3. Last night I had some questions about how the cipher list in Stunnel interacts with the cipher negotiation routine between client and server, so I did some experiments in an attempt to address those questions. In the course of doing so, I noticed that, if I attempt to load certain ciphers, Stunnel would stall at configuration load. Using OpenSSL to list TLS ciphers with 4.52's libraries yields the following: ~~~~~~~~~~~~~~~~~~~~~ C:\Program Files\stunnel>openssl ciphers -v -tls1 DHE-RSA-AES256-SHA SSLv3 Kx=DH Au=RSA Enc=AES(256) Mac=SHA1 DHE-DSS-AES256-SHA SSLv3 Kx=DH Au=DSS Enc=AES(256) Mac=SHA1 AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 EDH-RSA-DES-CBC3-SHA SSLv3 Kx=DH Au=RSA Enc=3DES(168) Mac=SHA1 EDH-DSS-DES-CBC3-SHA SSLv3 Kx=DH Au=DSS Enc=3DES(168) Mac=SHA1 DES-CBC3-SHA SSLv3 Kx=RSA Au=RSA Enc=3DES(168) Mac=SHA1 DHE-RSA-AES128-SHA SSLv3 Kx=DH Au=RSA Enc=AES(128) Mac=SHA1 DHE-DSS-AES128-SHA SSLv3 Kx=DH Au=DSS Enc=AES(128) Mac=SHA1 AES128-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA1 IDEA-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=IDEA(128) Mac=SHA1 RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH Au=RSA Enc=DES(56) Mac=SHA1 EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH Au=DSS Enc=DES(56) Mac=SHA1 DES-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=DES(56) Mac=SHA1 EXP-EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH(512) Au=DSS Enc=DES(40) Mac=SHA1 export EXP-DES-CBC-SHA SSLv3 Kx=RSA(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-RC2-CBC-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export C:\Program Files\stunnel> ~~~~~~~~~~~~~~~~~~~~~ As such, ciphers RC4-SHA and RC4-MD5 appear to be valid.

I generated 480k+ stunnel transactions. This morning, stunnel memory usage is virt=187m and res=42m. My result after 40k transactions was exactly the same (in both cases with pthread+zlib). > I understand that virt includes shared libs, and that any issue with a >> shared lib will impact virt size.

This is at least what I see under my setup and type of usage. pthread+zlib, 40k transactions before: virt=20680, res=792 after: virt=187m, res=42m pthread+nozlib, 40k transactions before: virt=20688, res=896 after: virt=185m, res=39m I have seen no benefit of compiling without zlib in fork mode. I guess it only makes forking a bit lighter. 2012/3/5 Michal Trojnara <Michal.Trojnara(a)mirt.net> > You may also try to set a lower value of MMAP_THRESHOLD to reduce heap > fragmentation: > https://www.kernel.org/doc/man-pages/online/pages/man3/malloc.3.html > This will be worth a look. Knowing what is influencing stunnel size is nice since it can avoid us restarting the processes once in a while (which we currently never do in fork mode). Thanks for your great help!

How to pass remote IP to local SMTP/POP3 server
by Zdenek Valach (INBOX) 08 Mar '12

08 Mar '12

Hi I have question, because I was not able to find answer anywhere on internet. I started to use Stunnel in server mode to provide POP3S/SMTPS functionality. Everything works fine except that I am missing remote IP of connecting client. I am using Windows version so I can not use transparent proxy mode working on Unix. Is there way how to make Stunnel for example after each establishment of TCP connection to send to SMTP/POP3 server port some special command like REMOTEIP 123.123.123.123<crlf> to pass this information there. I know it is not in SMTP/POP3 standard but it is simple for me extend behavior of SMTP/POP3 service by this command? Thank you very much for any advice Zdenek ____________________________________________________________ FREE 3D MARINE AQUARIUM SCREENSAVER - Watch dolphins, sharks & orcas on your desktop!

mknod: not owner building stunnel on Solaris SPARC 10 zone
by Jiri ROHLICEK 07 Mar '12

07 Mar '12

Hello,I've been building stunnel 4.52 on Solaris 10 SPARC zone. Configure and make went fine, make install failed in tools with error if uname | grep SunOS; then \ ../auto/install-sh -c -d -m 755 /tmp/stunnel/var/lib/stunnel/dev; \ mknod /tmp/stunnel/var/lib/stunnel/dev/zero c 13 12; \ chmod 666 /tmp/stunnel/var/lib/stunnel/dev/zero; \ fi SunOS mknod: Not owner -- mknod is not allowed in solaris zone, only in global. One of many notices of this error skayser's http://www.mail-archive.com/[email protected]/msg03031.html asks if mknod is needed on solaris 10. So I tried after configure comment out the mknod section in tools/Makefile. -- install-data-local: ... ... if uname | grep SunOS; then \ ${INSTALL} -d -m 755 $(DESTDIR)$(localstatedir)/lib/stunnel/dev; \ mknod $(DESTDIR)$(localstatedir)/lib/stunnel/dev/zero c 13 12; \ chmod 666 $(DESTDIR)$(localstatedir)/lib/stunnel/dev/zero; \ fi -- Now make install ends OK and stunnel works fine (I use it as client only). Isn't creating ./dev/zero not needed anymore? Thanks Jiri Rohlicek jrohlicek(a)aplis.cz

Username and Password in Stunnel
by Jim Murphy 07 Mar '12

07 Mar '12

I have a program that only allows me to enter a From email address and a mail server IP in its setup. Is there any way that I could enter a username and a password in stunnel.conf and let Stunnel send this information out to Office 365 or Gmail for delivery? Thanks! Jim
