Stunnel on Android 7.x not working?
by John Appleseed 14 Oct '17

14 Oct '17

Hello, I have trouble with stunnel on Android 7.x.. I'm trying to connect to OpenVPN server through SSL tunneling with stunnel. On phone I'm using stunnel installed in Termux and OpenVPN. Everything is correctly configured, Im using the same config on other devices in same network and it works perfectly. I tried it with different devices with Android 7.x and it is not working at all :( Immediately after succesful connection I am receiving: TLS fd: Software caused connection abort (103) TLS socket closed (SSL_read) And it is still reconnecting again and again with the same error. I also tried it with stunnel downloaded directly from stunnel.org site.. Anyone with new Android who have working stunnel? Where can be the problem? Example stunnel.conf on Android: socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = debug [openvpn] client = yes accept = 1337 connect = *****.ddns.net:993 cert = /path/to/stunnel.pem and on server: chroot = /var/lib/stunnel4 pid = /stunnel.pid output = /stunnel.log setuid = stunnel4 setgid = stunnel4 socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [openvpn] client = no accept = 993 connect = 127.0.0.1:1194 cert = /etc/stunnel/stunnel.pem Example stunnel.log is in attachment. Thank you very much

No certificate or private key specified

Hi, After overcoming some initial more obvious problems I have still been unable to get this client's stunnel configured correctly. "No certificate or private key specified" - is this significant?

Comments on daily DH Parameters regeneration...
by Taed Wynnell 06 Oct '17

06 Oct '17

We've been experiencing pain due to the daily STunnel regeneration of the DH Parameters. On our single-core machines in the field, this process will use 100% of the CPU for possibly an extended time. This interferes with other tasks that the machine is intended for. What's odd is that this process time ranges wildly, ranging from as low as 3 seconds to 90 minutes, even on the same machine. We see this behavior on all (thousands) of our machines, now that we know what to look for (the "Cron jobs completed in" trace in stunnel.log). We now know that we can set the DH Parameters in the configuration file, and that's what we'll be doing going forward. (Unless someone has another idea to offer.) I'd like to suggest some ideas for the future since I've seen on the mailing list that there are others who have run into this issue: * If the DH Parameter regeneration would run at Idle priority instead of Normal priority, it would not be nearly as noticeable, in that the CPU usage would still be there, but it wouldn't impact other services. The recomputation may be done in a separate thread, if so, this is straight-forward. * If there were a configuration file parameter to specify the regeneration interval. It would default to 24 hours (which is the current behavior), but could be set to a longer interval, a shorter interval for extreme security, or even to never. STunnel would still regenerate at the time of the service starting, unless a fixed DH is found in the configuration file. If a fixed DH were specified in the configuration file, that would avoid the service start computation and the interval would default to never. If both a fixed DH and the interval were specified in the configuration file, it would use the specified interval and recompute only after that interval.

Using Chrome directly as an STunnel Client to connect to an STunnel Server
by Dipen Doshi 05 Oct '17

05 Oct '17

Hello, I am new to STunnel and I am running into a problem. Here is my setup. I use an ASUS router with Merlin firmware. I have STunnel installed via Entware on this router. Running "stunnel -version" gives me: stunnel 5.41 on mipsel-openwrt-linux-gnu platform Compiled/running with OpenSSL 1.0.2k 26 Jan 2017 Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI Global options: RNDbytes = 64 RNDoverwrite = yes Service-level options: ciphers = FIPS (with "fips = yes") ciphers = HIGH:!DH:!aNULL:!SSLv2 (with "fips = no") curve = prime256v1 debug = daemon.notice logId = sequential options = NO_SSLv2 options = NO_SSLv3 sessionCacheSize = 1000 sessionCacheTimeout = 300 seconds stack = 65536 bytes TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none ------------------------------------------------------------------------------------------- I use my own server certificate signed by my own CA. This cert has the proper SANs with correct DNS/IP entries. I use this server certificate both for my router's HTTPS web gui and for the "cert" and "key" files listed in the config file below. Also, the "CAfile" in the config is pointing to my Root CA's certificate. My Root CA is also imported in my Windows box's certificate store. I can directly access my router's web gui from LAN side via these ports: 80 (HTTP), 2000 (HTTPS). Router's LAN subnet is 10.49.49.0/24 and the router's WAN IP is 10.76.5.3 (it is double NAT for testing, this router is for testing) Also, STunnel is running as a server accepting connections on port 443 (all interfaces) on the router. ------------------------------------------------------------------------------------------- I want to use Chrome directly as an STunnel client on my Windows box. So, I don't run STunnel on my Windows box in the client mode. SITUATION 1: WORKS FINE!! -- PURPOSE: Use Chrome to connect to "https://WAN_IP:443" This should forward to the router's port 80 (HTTP protocol used). My STunnel config file on the router has: setuid = nobody setgid = nobody foreground foreground = yes syslog = yes debug = 7 [Test-Service] accept = 443 connect = 10.49.49.1:80 requireCert = yes verifyChain = yes CAfile = /mnt/Merlin/entware/etc/stunnel/ca.crt cert = /mnt/Merlin/entware/etc/stunnel/server.crt key = /mnt/Merlin/entware/etc/stunnel/server.key SITUATION 2: DOES NOT WORK!! -- PURPOSE: Use Chrome to connect to "https://WAN_IP:443" This should forward to the router's port 2000 (HTTPS protocol used). There is only one change from the Situation 1 config file. The line for "connect" changed to "connect = 10.49.49.1:2000) This does not work. Note that I can directly access my router's web gui over https with "https://LAN_IP:2000" via Chrome, with no warnings. ------------------------------------------------------------------------------ My thoughts: So, my current path is Chrome (Acting as STunnel Client) --> STunnel Server (on the router) --> Router's Web GUI. The "Chrome --> STunnel" Server connection is fine. Chrome prompts for private key and STunnel server correctly shows this incoming Chrome connection. The problem is the "STunnel Server --> Router" relay that uses HTTPS protocol. 1. STunnel does not like HTTPS to HTTPS relay. HTTP to HTTPS works, but not HTTPS to HTTPS. 2. STunnel server on my router is a client to my router's web gui. Is STunnel verifying the certificate of my router's HTTPS certificate? 3. If the above answer is yes, my guess is that STunnel sees a self signed certificate for this router and kills the connection? 4. How do I tell STunnel server to ignore certificate warnings for a remote connection, like when connecting to this router? 5. Or how do I explicitly tell STunnel to trust my Root CA while making this connection to my router? I couldn't find any options in STunnel for this. Regards, Dipen Doshi

Bug: Modifying configure.ac results in error
by Reschke, Sven (VWIF G-TS/P) 22 Sep '17

22 Sep '17

Hallo, I've encounter a problem when editing the configure.ac. I've upgraded to Stunnel 5.42, the problem wasn't existent with Stunnel 5.41. The normal operation is that "./configure" and "make" will run without an error. So far, so good. Now, if I edit the configure.ac, running again "./configure" and "make", "make" will report: CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh <path_to_stunnel_sources>/stunnel-5.42 /auto/missing aclocal-1.14 -I m4 cd . && /bin/sh <path_to_stunnel_sources>/stunnel-5.42 /auto/missing automake-1.14 --gnu CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh <path_to_stunnel_sources>/stunnel-5.42 /auto/missing autoconf configure.ac:4: error: possibly undefined macro: AC_MSG_NOTICE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.ac:23: error: possibly undefined macro: AC_DEFINE make: *** [configure] Error 1 Here it doesn't matter what I change in configure.ac. Even the slightest modification results in the error. After some investigation, running "make" with "-d" showed that it will call auto/missing, because of the newer version of configure.ac. Comparing aclocal.m4 before and after calling "make" shows, that mainly the lines added between the version 5.41 and 5.42 are missing now (lines #23 - #741). As I'm not so familiar with the whole compile process, I found a simple hack, which solves the problem for the moment: Adding these missing lines to a new file named m4/acinclude.m4. After that, compiling, installing and running Stunnel works fine. Can someone verify? If you have questions, I'll try my best to answer them :) Best Regards, Sven Reschke Embedded System SW Developer G-TS/P

stunnel w & w/o data compression
by Daniele Basaldella 18 Aug '17

18 Aug '17

Dear all, I use stunnel in clinet configuration to get data feeds from several sources. Until now none of them requested data compression, so the configuration was easy. Now I need to connect to a new data feeder that requires zlib compression. I found the compression method is a global setting, so it will be not compatible with current setup. The server runs Ubuntu 16.04LTS, ker 4.4.0.92.lowlatency, stunnel 5.30, openssl 1.0.2.g. I looked for a solution on internet but seems no one have my issue. Someone could suggest how to get both compressed/uncompressed data feed connections on same system. Thank you Best Regards Daniele

Timeout issue I think
by Ben Bazian 16 Aug '17

16 Aug '17

I have a legacy server that uses IMAP but does not support TLS. I am using stunnel and since implementation I am getting errors when an email has a larger attachment. My application process these attachments and when done (sometimes can take 5-10 minutes) it marks the message for deletion. When all messages are completed it purges the emails from the box. My app is throwing an error when it tries to delete the message (see below). I think it may be due to stunnel closing the connection to the server?

logging real client IP in Apache
by Stoyan Stoyanov 07 Jul '17

07 Jul '17

I have an Apache server serving only HTTP requests on port 80 and an stunnel daemon on the same server listening on port 443 and tunneling HTTPS requests to Apache. Is there a way for the client IP to be passed on to Apache so that I can capture and log that instead of the IP of stunnel, which in this case is 127.0.0.1? Ability to add a variable to the HTTP header would be perfect, but any other suggestions to solve this problem are welcome. Thanks! Stoyan

Error on startup of Stunnel
by Shelstone Lorde 30 Jun '17

30 Jun '17

I installed version 5.41, the latest version, on a Windows 10 Pro machine. I placed a link to the Stunnel.exe file in the Startup folder. I am getting the error "The ordinal 3253 could not be located in the dynamic link library c:\Users\...Programs\Startup\stunnel.exe". May be there has been a previous posting concerning this error but I have not been able to find it. Any help or suggestion will be appreciated. Thanks.

Then, you told Stunnel, if such a connection is accepted, to connect to a remote server at port 8228 ("connect = 69.191.198.34:8228"). As long as both connections are established, Stunnel will forward data from localhost to 69.191.198.34 and vice versa, while encrypting the data in the localhost -> 69.191.198.34 direction and decrypting the data in the opposite direction (69.191.198.34 -> localhost). With this setup, a client program (such as Thunderbird) sends and receives plain-text data to/from a Stunnel instance on the same machine, while a server program on a remote machine (such as the Google mail server) sends and receives encrypted data to/from Stunnel. Is this about the setup you have in mind? Is your application server or client? Does it send and receive plain-text data or encrypted data?

Configuring stunnel and openssl on Windows to support TLS 1.2
by Liz Turi 13 Jun '17

13 Jun '17

Good morning, I'm hoping you can help point me in the right direction. The problem I'm trying to solve is enabling TLS 1.2 connections on a Windows (environment has both Windows 2008 and Windows 10 environments) platform. Currently, my private keys are managed by the Windows certificate store, using the capi engineId within stunnel (v 5.41), which uses OpenSSL 1.0.1. Because of this, stunnel can only negotiate a TLS 1.1 connection. I've tried compiling OpenSSL 1.1.0f and stunnel 5.41, but no luck either cross compiling under CentOS, nor under Windows using either MSYS2/MINGW32 or Cygwin. What I'm looking for is any one of the following 1) solid current cross-compiling examples or references 2) solid current Windows compiling examples or references using extant versions 3) a way to manage the pfx/p12 (private key) in stunnel without resorting to the Windows certificate store. Option 3 is preferred. I see how to manage pkcs11, but not pkcs12. Thank you in advance!

Memleak sTunnel Win32 5.41 ?
by Dod 12 Jun '17

12 Jun '17

Hello, I just noticed that stunnel memory usage is growing slowly but surely using 5.41 on Win7 64 Bits. Using a few POP3 SSL tunnels. Now it is using 290MB memory I don't know if it is since 5.41 (didn't pay attention). Is there a way to trace/log something that could be useful ? (apart from the process memory usage curve that I guess will not help). regards.

TLS-SRP patch
by Kevin Sheldrake 06 Jun '17

06 Jun '17

Hello I recently produced a patch that permits use of TLS-SRP; it is based on the TLS-PSK code and this blog post: https://matthewarcus.wordpress.com/2014/05/10/srp-in-openssl/ It’s not the cleanest of code but it does work as a POC. The patch is available here: https://github.com/rtfcode/tls-srp The README.txt provides some info on testing the patch and how it might be used to help dev web browsers and servers that support TLS-SRP (for IoT work). There is a page on the forthcoming OWASP Summit ‘TLS for Local IoT’ workshop (for which it was developed) at: https://owaspsummit.org/Working-Sessions/IoT/TLS-for-Local-IoT.html In terms of using TLS-SRP support in stunnel as a proxy, it might be useful as a replacement for TLS-PSK where the credentials are user-memorable (pass phrase, for example) as TLS-SRP has lower entropy requirements than TLS-PSK. For example, the creds could be stored in the user’s head rather than in a file and be less open to compromise if a device was seized. I don’t know if that’s useful for anyone; it’s just a thought. Thanks Kev

Stunnel on Suse 8.1, connections refused, pid remains
by InvalidPath 09 May '17

09 May '17

So I have this server, I can start stunnel via /etc/rc.d/stunnel start. The pid is there as witnessed by ps -aux | grep stunnel, I have 4 customers that access this server. The customers pull data files that contain certain client records. Anyway my test user connects to the server and is able to pull a handful of files before their process begins timing out. When this happens I can no longer SSH to the host without restarting stunnel. Weird thing is, is that I can see the pid still running when this happens. I have the debug = 7 but the log files according to stunnel - version is set to a level of 5. No clue where it''s getting a 5 from. But I am unable to determine why or what is causing this. And it's starting to cost the company lost revenue. Any help would be greatly appreciated. Ben

Graceful config reload when -fd option was used
by z a 09 May '17

09 May '17

Hi, Since version 4.30, sending a HUP signal to a running stunnel process will cause it to gracefully reload with the given config file. Is there a way to accomplish this when the running stunnel process was started with the "-fd" flag as in the example below? cat foo.conf | stunnel-fd 0 I tried writing to /proc/$pid/fd/0 but that didn't work. I'm hoping someone here has overcome this issue and might be able to whisper a hint in my direction. I am on Centos 7.2. Thanks

Windows Server 2012 stunnel service
by Adam Shackleton 18 Apr '17

18 Apr '17

Hi All I'm running stunnel on Windows Server 2012 R2 with the following config: [test-qa] client = yes accept = 127.0.0.1:8080 connect = webaddress.com:443 cert = API-q-response.pfx CAfile = ca-certs.pem OCSPaia = yes When I start the GUI I'm prompted for the certificate password then and then stunnel works fine, but I need it to run as a service. I've tried using the start menu stunnel Service Install button, I've also tried opening a command prompt in C:\Program Files (x86)\stunnel\config and running C:\Program Files (x86)\stunnel\bin\stunnel.exe -install, and I've also tried moving the config file and certs to the \bin directory and running stunnel -install there as well. In all case the service installs ok, and when you run it, it starts (I can see it in the services tool), you can click the stunnel Configuration File Reload button in the start menu and it says the configuration was successfully reloaded, but it doesn't work when I try to use it. I've noticed two things that might be relevant: 1. At no point does it prompt me for the certificate password like it does when I load the GUI 2. The dialog boxes that open when the service is installed or started say "stunnel 5.40 on Win32 (not configured) [cid:[email protected]] If anyone has any advice that would be greatly appreciated. Thanks Adam

SOCKS connection to the IPv4 loopback rejected.
by Robert de Bath 15 Apr '17

15 Apr '17

Hi everyone, How do I get rid of this message? I have a stunnel server setup on a remote machine using the socks protocol. I use two keys plus the certificates and a private CA to protect the SSL link. On a local machine I have an stunnel client running without a protocol option set. If I try to make a socks connection to an interface IP of the remote server it works perfectly, bypassing the intervening firewalls through the protected tunnel. But the interface IP changes and I only want to allow connections to the remote server through the tunnel. I could setup traditional tunnels, but while one of the services (remote desktop to the Windows server) is constant the others are dynamically configurable. I have even considered using SNI to distinguish the incoming connections to the various services but while this allows there to be just one tunnel port it will still need a remote reconfiguration of stunnel every time a service port is added or removed. The best way to express this limit is that the socks server should ONLY connect to localhost; but it's "rejected". In actual operation I will probably need to allow the local network too which will probably be an rfc1597 address. Looking at the source it appears that this condition is hard coded into the "validate" function so my question becomes: can you please remove this or add a flag to turn it off? -- Robert de Bath robert(a)tvisiontech.co.uk

PSK, verifying the client
by Mike 05 Apr '17

05 Apr '17

Is it possible to verify the client using PSK? On the stunnel server I specify a PSKsecrets file with two lines in it, one for client01 and one for client02. The secret is about 36 characters long. On a client, I have a similar PSKsecrets file, but only containing the client01 line. Now, if I try to connect with, say, a client03, i.e., any client that does not have a matching line in the server's PSKsecrets file, how can I assure that the client connection will be rejected? What I'd like to see would be the following: any client that tries to connect, and does not present a PSK that is present in the server's PSKsecrets file, then that client's connection request is rejected, with an appropriate message logged. Can I do that with the current stunnel? thx.

Scan to email failure: RapbianPi3 to Office365
by Graeme Ellisson 03 Apr '17

03 Apr '17

Hi. I recently bought a Pi3 and have loaded Raspbian with Doobs (Previously I had this running faultlessly under a Windows Server for my Canon multi function printer that does not support SSL/TLS but only authentication). After about 8 attempts to get Stunnel4 working (there doesn't seem to be a later version to install via the command line) I eventually found that Stunnel4 works fine as long as one doesn't update Dabian from the initial Doobs install. So, I now have the service running and listening on port 25 with the following config file: debug=7 output=/etc/stunnel/stunnel.log client=yes options=NO_SSLv2 (I added this last night after reading a

Stunnel Version Vulnerability-Currently using 5.04
by Tracy Drake - IQGC-C 28 Mar '17

28 Mar '17

Hello Stunnel Users Forum! I wonder if anyone may have suggestions of what, if anything can be done to surmount a reported vulnerability for Stunnel versions prior to 5.34. I have limited savvy in this arena so please excuse this "Stunnel for Dummies" question. The following statements surfaced in a "security vulnerabilities" report... The version of stunnel installed on the remote host is 4.46 or later but prior to 5.34. It is, therefore, affected by a security bypass vulnerability related to the validation of level 4 peer certificates. An unauthenticated, remote attacker can exploit this to have an impact on confidentiality, integrity, and/or availability. No other details are available. I am of the mind that perhaps an entry in Stunnel.conf until we can deploy an upgrade? Thanks in advance for any feedback! Upgrade to stunnel version 5.34 or later. -- Tracy Drake CSM Senior Consultant GSA-FAS CAMEO Contractor URSA & INFOConnect Support & Training Team Lead 704-987-1211 tracy.drake(a)gsa.gov

by Aykut SAY 24 Mar '17

24 Mar '17

Hi, We are working on a integration project and we need to connect our application to three different sources. These three sources have their own VPN. Can stunnel connect to three different vpn from one server? If yes, which version of stunnel we need to install to our server? Thanks, Aykut

stunnel public private key authentication like ssh
by Michael Power 23 Mar '17

23 Mar '17

Is there a way to configure stunnel just to check the public key of the provided certificate? I want authentication between the server and the client to take place by public key only, no PKI just like ssh. Is this possible? Is this verify level 4, or does that still check the CN against the host that I am connecting to? Michael Power

update stunnel with engine pkcs11
by Heinsbroek, Peter 20 Mar '17

20 Mar '17

Hallo, I’m a newbee in C programming. I have to upgrade stunnel 5.31 with engine_pkcs11 (0.1.8) for windows to the latest versions. (5.40 & 0.2.2) My engine_pkcs.c contains an subroutine my_get_pin (see attachment line 707) that reads a pin from a file in the windows folder. After reading it ,it transforms the pin to hexadecimal, if not already done, and writes it back in the file. After adjusting the new source it compiles without errors, but when executing it doesn’t work anymore. I also attached the old engine_pkcs11.c as we used it. Can someone help me with this problem. After compairing the old and new source I noticed that there have been major improvements to the source With regards, Peter Heinsbroek Application manager NT / SQL20xx Tel. +31 (0)88 265 9869 Mob. +31 6 5375 3244 Werner von Siemensstraat 3 2712 PN Zoetermeer, Nederland Org. unit PS Central Fin Services Unit 02 SI NL Email peter.heinsbroek(a)atos.net<mailto:[email protected]> Web www.nl.atos.net<UrlBlockedError.aspx> Atos IT Solutions and Services B.V.

Fwd: Stunnel Performance strangeness
by Scott McKeown 10 Mar '17

10 Mar '17

Hi All, We have been doing some throughput testing and are wondering of you can help explain some of the results we have been getting. We are trying to establish the maximum number of handshakes per second our appliances can do when using Stunnel. Our tests have been done on a 4 core Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz machine with 8Gb ram. Using stunnel 5.33 openssl 1.0.2j (We use stunnel 5.33 here, but this was also tested with stunnel 5.40 and we got the same issue) Stunnel was compiled with - ./configure --enable-fips --enable-ipv6 --with-threads=pthread --sysconfdir=/etc --with-ssl=/usr/src/built/OpenSSL_1_0_2j-no_march/usr/local/ --disable-libwrap --disable-systemd I was using a python script of my own design for load testing when I noticed the problem we then switched to an open source package called vegeta https://github.com/tsenart/vegeta the command I was using to run it was - echo "GET https://10.10.10.10:443" | ./vegeta attack -workers=30 -rate=3000 -duration=300s -insecure > test.out We are essentially seeing a degradation in throughput at a fixed point in time. I am seeing the problem when using 3000 transactions per second. We are doing https gets through stunnel to a http backend, 1 transaction is an ssl handshake the http get and waiting for the response. Interestingly if I try 5.06 it works fine I get a smooth constant loading. Please take a look at 30worker3000rate5.33-300s.png where you can see after about 55 seconds there is a jump in latency. I get the same issue if I run the test with 2000 transactions. Please see 30worker20005.33-700s.png but with the lower transaction rate the issue takes longer to rear its head. The issue doesnt happen if I run the test with 3000 transaction using 5.06. Please see 30worker3000rate5.06-300s.png >From looking at the graphs our thoughts were that we were hitting some sort of cache limit and used that as a starting point. We have taken a look at the code changes between versions we know were working and the problematic version and the main thing that stands out is the changes to the leak detection. Previously this was partially based on the number of clients but has been changed to use the sections. This led to the decision to try a different limit value and found the number of connections we saw before seeing an issue corresponds to the change of the limit value. We think we have identified the code that is causing the problem/doing something funny it was added in 5.33 NOEXPORT long leak_threshold() { long limit; limit=10000*((int)number_of_sections+1); #ifndef USE_FORK limit+=100*num_clients; #endif return limit; } its src/str.c when increasing the limit number so limit=10000*((int)number_of_sections+1) to limit=20000*((int)number_of_sections+1) This still results in an increase in response time but at a later time in the test, please see 30worker3000rate5.33-ben-highlimit.png Interestingly once I end up in this state I am stuck with high latencies until I restart stunnel. (The box I am testing on was left over night to make sure its not any hanging tcp connections or anything like that) I must admit we are at the limit of our C understanding and your imput would be welcomed. -- With Kind Regards.

Segfault after connecting
by Andrew Culver 23 Feb '17

23 Feb '17

I had my stunnel instance working as expected last week. Since then I've moved the server behind a load balancer, which is doing regular health checks (opens a tcp connection, then disconnects) to see that stunnel is up. I don't believe the health checks are a problem, but they're the only change I've made since I had stunnel working. I can see the health checks connecting and disconnecting. However when I open a new connection, either by telnet or by: openssl s_client -connect mtar.uwo.ca:587 -starttls smtp ... stunnel says it fails to verify the server certificate, then seg faults. I'm running stunnel 5.40 and I'm having the same problem on 2 different servers running openssl 1.1.0d and 1.1.0e. Here's my config: [root@mtar1 stunnel]# egrep -v '^;|^ *$' stunnel.conf ; Sample stunnel configuration file for Unix by Michal Trojnara 2002-2017 setuid = stunnel setgid = stunnel pid = /usr/local/var/run/stunnel/stunnel.pid foreground = yes debug = debug [uwo2local] accept = 587 cert = /usr/local/etc/stunnel/mtar-withprivatekey.pem connect = 20587 protocol = smtp [local2o365] client = yes accept = 127.0.0.1:20587 connect = smtp.office365.com:587 checkHost = smtp.office365.com verifyChain = yes CApath = /etc/ssl/certs OCSPaia = yes protocol = smtp Here's my debug log: The health checks are from 172.18.58.5 and my test connection which leads to the seg fault is from 129.100.6.17.

Bad Magic
by Melzer, Jacob 21 Feb '17

21 Feb '17

I'm trying to do a proof of concept using Stunnel on AIX 6.1. Without stunnel I'd have: Telnet session -> listening service With stunnel, I want: telnet session -> stunnel client -[secure connection]--> Stunnel server -->listening service. The stunnel client seems to be working fine, but the stunnel server abends as soon as it receives a secure connection. Client: Accepts non-secure on port 33342.

stunnel on Windows Client: Changing active network interface (wired, wireless)
by b.koch.kemper 17 Feb '17

17 Feb '17

Dear stunnel community, we are running an application on our windows clients. The application needs a remote connection to our server (linux) for remote function calls. We could successfully secure this connection via stunnel. However, when our windows users change their network connection (e.g. they disconnect their notebook from the docking station to our corporate wifi) the connection and hence the whole application breaks. The users actually have to restart stunnel to make the application work again, which is really inconvenient. As the application on the notebook is always using the same port, is it somehow possible to make stunnel establish a new connection using the new active network interface? Kind regards, Bernhard

RSA too big problem
by Vikrant Agarwal 16 Feb '17

16 Feb '17

Hi, I upgraded my Stunnel server machine to CentOS 6.8 and post upgrade , the stunnel too got upgraded to stunnel 4.29 on x86_64-redhat-linux-gnu with OpenSSL 1.0.1e-fips 11 Feb 2013 . Now since then many of the stunnel client using newer stunnel client (those uses TLSv1.2 for Negotiation) are not able to connect . I get below error on the server in logs RSA_sign:digest too big for rsa key:rsa_sign’ How to fix this please? Regards, Vikrant

Re: [stunnel-users] Problem with 5.40 and Peer suddenly disconnected
by Brian McGinity 08 Feb '17

08 Feb '17

I found the archives and downgraded to 5.37 and this fixed the problem. Before going this route I tried 5.40 and 5.41 beta and both had the same issues with 'Peer suddenly disconnected'. Strange that it this was only happening for one particular connection (1 out of 7). It would happen with every test. If you would like for me to beta test another version, I would be happy to try.

Problem with 5.40 and Peer suddenly disconnected
by Brian McGinity 07 Feb '17

07 Feb '17

After updating to stunnel 5.40 on x86-pc-msvc-1500 platform, I am getting a Peer suddenly disconnected each time I post data to a particular url. [VISION_WEB] client = yes accept = 127.0.0.1:1935 connect = xx.xx.web.com:443 sslVersion = TLSv1 2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] accepted connection from 192.168.100.21:53507 2017.02.07 16:30:08 LOG5[160]: s_connect: connected 11.11.111.36:443 2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] connected remote server from 192.168.100.21:53508 2017.02.07 16:30:08 LOG3[160]: SSL_connect: Peer suddenly disconnected 2017.02.07 16:30:08 LOG5[160]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket This is a production issue and is causing a lot of problems for a lot of people and I need to do something quickly. Is it possible to download stunnel 5.37 installed to see if going back to this version will fix this issue? Where is it? Or does anyone possibly know why this might be happening? Thank you for your help. Brian

Default passthrough to different destination?
by Mark Boyce 03 Feb '17

03 Feb '17

Hi All Wondering if there’s a way to pass an unencrypted connections traffic to an alternative location if a client does not SSL/TLS with the stunnel server? So considering stunnel running as a server to wrap an unencrypted SMTP server. If the SMTP client/server talks SSL/TLS all is good and as expected. If the client tries to talk without encryption it gets disconnect. Is there any way to send this traffic elsewhere rather than disconnecting the client? So that stunnel is adding an SSL/TLS option to a service rather than enforcing it. Splitting the traffic to destination servers based on if the client was encrypted or not. Thoughts? Thanks Mark

Mixed cert/PSKsecrets & TLS/SSL before proxy
by Varda Zklir 02 Feb '17

02 Feb '17

Hello Gentlemen. Needs help in configuration or negative clarifications on two issues. 1) First question whether is mixed use of cert/PSKsecrets auth possible? The same method (ether cert or PSKsecrets explicitly) serverside trough the parent [TLS] and inherited services works properly. But mixed cert/PSKsecrets like in config snippet below doesn't work. [TLS] client = no accept = 0.0.0.0:https connect = localhost:http cert = /etc/opt/stunnel/stunnel.pem [ssh] client = no sni = TLS:ssh connect = localhost:ssh [socks] client = no sni = TLS:socks protocol = socks PSKsecrets = /etc/opt/stunnel/auth/passwd The idea is to pass insensibly all incorrect or non-SNI aware requests to main http server and hide other multiplexed services. And at the same time to establish encryption and password access control to [socks] service. 2) And the second question is it possible proxy CONNECT after establishing SSL/TLS encryption? The configuration section: [ssh] accept = 22222 protocol = connect protocolHost = server.tld:443 protocolUsername = usernamehere protocolPassword = passwordhere connect = proxy.tld:8080 Say to establish unencrypted connection with proxy, pass username and password, tell proxy to establish CONNECT to target 443 and then transmit SSL/TLS to it. Goal is if I have SSL/TLS termination server/proxy on port 443 so we at first speak SSL/TLS with proxy and only then proceed to proxy requests phase. Thanks for future explanations.

installation problems
by HOFFMAN, GEOFFREY 30 Jan '17

30 Jan '17

I am having trouble installing stunnel on CentOS 7.3. I was given a directive to "use the latest OpenSSL" so on one target machine, it has 1.0.2k built from source. On the machine with OpenSSL 1.0.2k, when attempting to install stunnel, when I run ./configure, it passes with this info: configure: FIPS support not found Then make fails with: /usr/bin/ld: /usr/local/ssl/lib/libssl.a(s3_srvr.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC On another target machine, it has 1.0.1e-fips, installed via yum package. On the machine with OpenSSL 1.0.1e-fips, ./configure fails with: checking for TLS directory... not found configure: error: Could not find your TLS library installation dir Advice on installing with the latest OpenSSL (1.0.2k) would be much appreciated.

Life cycle information
by Ben Harper 30 Jan '17

30 Jan '17

Greetings, I am trying to confirm some life cycle information, mainly supported version(s) and what versions do not insure backwards compatibility. It would appear that only the latest version is supported, per the first item under 'Before you send your question to stunnel-users' on the Mailing Lists page[0]. Does this project use semantic versioning? Will incompatibilities only come when a 6.x.x version is released? It seems at one point this was the case per the 'Upgrading to stunnel 4' link on the Documentation page[1]. Are my assumptions correct? Thanks, Ben [0]: https://www.stunnel.org/lists.html [1]: https://www.stunnel.org/docs.html

Proxy one site to HTTPS?
by Jeffrey Walton 30 Jan '17

30 Jan '17

Hi Everyone, I'm having trouble setting up a proxy for one site. The client is MacPorts on OS X 10.5. It makes some requests for files over port 80, but they apparently need to be made over port 443. Also see https://trac.macports.org/ticket/53423 and https://trac.macports.org/ticket/53347. My first question is, is it possible to proxy one site to HTTPS? My second question is, how does one do so if it is possible? The concrete example from the 53423 bug report is, I need to proxy requests from http://distfiles.macports.org/... to https://distfiles.macports.org/... I also need the opposite on the responses. Thanks in advance, Jeff

Client certificate using CAPI
by stunnel.org＠pepak.net 29 Jan '17

29 Jan '17

Hi! I am trying to use stunnel to connect to my own server using both a server and a client certificate. I got the tunnel to work, provided that the client uses a PEM certificate stored in a file. However, I would like to use CAPI, because that would allow me to use a smart card, which I finally got Windows to recognize (a nightmare of its own). Unfortunately, it seems that the client-side stunnel won't send a client certificate because the server-side stunnel will always close the connection with: SSL_accept: 140890C7: error:140890C7:SSL routines:ssl3_get_client_certificate:peer did not return a certificate My client-side stunnel log shows that server sent some kind of identification of all the supported client certificates to the client, but that's all - the client stunnel fails to follow through: TLS state (connect): SSLv3 read server key exchange A Client CA: emailAddress=some(a)email.com, O=Some name, CN=Pepak Yubico 4 White Client CA: emailAddress=root(a)email.com, CN=Pepak (root CA) TLS state (connect): SSLv3 read server certificate request A TLS state (connect): SSLv3 read server done A TLS state (connect): SSLv3 write client certificate A TLS state (connect): SSLv3 write client key exchange A TLS state (connect): SSLv3 write change cipher spec A TLS state (connect): SSLv3 write finished A TLS state (connect): SSLv3 flush data SSL_connect: Peer suddenly disconnected As far as I can tell, the CN=Pepak Yubico 4 White matches what my Windows show as the name of the certificate on the smartcard. Following up on https://www.stunnel.org/pipermail/stunnel-users/2016-February/005393.html, I tried to add a "key = Pepak Yubico 4 White" line to the client-side stunnel's config, but it doesn't seem to have any effect. What could be the problem? The client-side config file is: compression = deflate debug = debug fips = no taskbar = no options = NO_SSLv2 engine = capi [echo-client] client = yes accept = 3000 connect = 10.0.0.1:30000 requireCert = yes verifyChain = yes verifyPeer = yes CAfile = desktop.pem engineId = capi key = Pepak Yubico 4 White The only suspicious thing that I see is that my client certificate says that its only purpose is to verify the identity of the remote computer. Could that be the reason the handshake fails? Thanks for any help. Pepak

SSL errors do not trigger failover?
by Richard Monk 27 Jan '17

27 Jan '17

Hello! We are using stunnel to work around an SSL issue in another service, and set stunnel.conf up to do prio failover. We noticed something unusual. If the TCP session connects, but the SSL negotiation fails, it doesn't fail over to the next server on the list. I looked at the code for the latest version and this doesn't seem to be caught anywhere. What I saw in client.c shows that it only checks failover after trying to establish the TCP session, but then the SSL session happens later and doesn't give any info back to the failover code should something go wrong. Is this expected behavior, or should I look into a bug report / patch? I was thinking maybe a configurable option to allow SSL errors to trigger failover just like TCP errors. -- Richard Monk (rmonk(a)redhat.com) - Senior Principal Security Analyst Red Hat Inc. - Raleigh NC GPG Key ID: 0x942CDB25
