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.

ssl3 handshake error

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)

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.

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
