No Taskbar Icon
by Carter Browne 26 Sep '14

26 Sep '14

I have updated stunnel to version 5.04 on Windows 7 32 & 64 bit, Windows Server 2008R2, Windows Server 2012 and Windows Server 2012R2 and in no case does the icon appear. I explicitly set taskbar = yes in the configuration file. -- Carter Browne cbrowne(a)cbcs-usa.com

"Socket operation on non-socket" when trying to pass the configuration file as a file descriptor on OSX

Hello I'm trying to pass the configuration file with option fd. However, I get the following errors when I do : echo my configuration | stunnel -fd 0 This is not related to echo since I get the same errors with: cat conf | stunnel -fd 0 stunnel is just filling my logs with : 2014-07-13 6:48:46.675 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) 2014-07-13 6:48:46.676 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) (...) stunnel ./conf works fine I found a reference to a bug that caused this same error message on OSX when run in inetd mode, but nothing else.

Stunnel as windows service doesn't start on restart.
by John Smith 24 Sep '14

24 Sep '14

Running stunnel 5.03 on Windows 2008 R2. Everything is installed and working fine. I can even start/stop the service no problem... (Pretty sure the service is set to start Automatically) When I reboot my server stunnel service shows as started but nothing gets logged and none of my connections work. Once I restart the service through service manager, everything works. So on startup it doesn't seem to run... This only happens if i reboot the machine. I also asked the same question here: http://serverfault.com/questions/627932/stunnel-as-windows-service-doesnt-s… Output of my logs proving it works. 2014.09.11 15:57:48 LOG5[1612]: stunnel 5.03 on x86-pc-msvc-1500 platform 2014.09.11 15:57:48 LOG5[1612]: Compiled/running with OpenSSL 1.0.1i-fips 6 Aug 2014 2014.09.11 15:57:48 LOG5[1612]: Threading:WIN32 Sockets:SELECT,IPv6 SSL:ENGINE,OCSP,FIPS 2014.09.11 15:57:48 LOG5[1612]: Reading configuration from file stunnel.conf 2014.09.11 15:57:48 LOG5[1612]: FIPS mode disabled 2014.09.11 15:57:49 LOG5[1612]: Configuration successful

Possible problem found in init script with 'dirty' config file
by F. J. Blanco 23 Sep '14

23 Sep '14

Hi there. Perhaps this is a foolishness, but it happens to me, triggering a great headache. I'm Debian (Wheezy) user, using stunnel 4.53-1.1. I copied the stunnel configuration from another machine for a simple LAN SMTP relay. When I tried to reload the script, I got this: # /etc/init.d/stunnel4 start > Reloading configuration SSL tunnels: /etc/init.d/stunnel4: 34: test: /var/lib/stunnel4/: unexpected operator A few hours laters, I discovered the problem was in config file, in the chroot parameter: chroot = /var/lib/stunnel4 Specifically, with a hide space at the end of the line: chroot = /var/lib/stunnel4[ ] In the init script, in the function get_pids(), this mistake caused that this checkout fails: --- if test -f $CHROOT/$PIDFILE; then cat $CHROOT/$PIDFILE fi --- 'cat /var/lib/stunnel4///stunnel.pid' is not the same as 'cat /var/lib/stunnel4/[ ]//stunnel.pid' Perhaps a suggestion, a little change here: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;"` Adding a space filter: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;" | tr -d " "` Regards.

John. Looks fine to me. Same configuration works in my Windows 7 64 bits. I have no access to Windows Server 2008 R2, but I would expect it to work the same. What are you securing with stunnel?...

Support for PSK
by Thomas Conté 21 Sep '14

21 Sep '14

Hello everyone, In the context of an embedded project, I have developed a lightweight, PolarSSL-based TLS-PSK client running on an Arduino board. Now I am looking for a generic server-side solution to connect the TLK-PSK client to a few Web services living in various app servers (Node.JS, IIS, and others). Since PSK support is not widespread, I am thinking about using stunnel as a generic front-end to these services. I have done a quick-and-dirty POC of adding PSK support to stunnel and it looks like this could be done with minor modifications, e.g. adding a call to SSL_CTX_set_psk_server_callback and the corresponding callback to ctx.c. Right now the psk_key and psk_identity values are hard-coded, so of course those need to be added to the configuration file. Is the community interested in further work in that area? Or is PSK support already in the stunnel roadmap? Cheers, -- Thomas Conté.

GnuTLS port
by Max 20 Sep '14

20 Sep '14

Pardon if that was asked before, but are there port of stunnel to GnuTLS available somewhere? With recent fallout from heartbleed I'm looking into getting rid of openssl (besides I've never liked the license anyway :) and stunnel is one of the very few programs which got dependency on it. cheers, Max.

400 - Bad Request
by j nasty 17 Sep '14

17 Sep '14

I'm trying to access a web service endpoint using sTunnel to handle all the SSL traffic. For my other connection setups this works perfectly fine. But for this one particular client I'm getting a 400 - Bad Request Error. Client Configuration looks like this: [Connection1] client = yes accept = 127.0.0.1:9006 connect = server.com:443 Response I get back is: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://server.com/"><b>https://server.com/</b></a></blockquote></p> </body></html> Is there a setting configuration I can use so that sTunnel redirects to https://server.com instead of server.com:443? Thanks in advance, Jake

Stunnel Windows Server 2008 R2

I have installed stunnel 5.03 on Windows Server 2008 R2 X64. When I run it as an application it works perfectly. When I install and run the service, it starts but the start notice window, title bar, says Stunnel 5.03 win32 (not configured). It appears that the stunnel service is not reading the stunnel.conf. If anyone has any suggestions how I can successfully run stunnel as a service, I would be very appreciative. Thank you!

Odd complication between VM clients, same host
by afpteam＠sbcglobal.net 24 Aug '14

24 Aug '14

Hi, Much appreciation to Stunnel and OpenSSL for a long, successful provision. I can't be sure yet if the concern below is Stunnel or OpenSSL related. I've surfed Google and found nothing similar. Stunnel package with integral OpenSSL is current release. I recently had to secure and connect two public facing client machines on the same Citrix Xen 6.2 release, running Server 2003 x 64 bit. I typically use Stunnel with self generated Pem, for securing short term TightVNC sessions. The config is always fairly generic, loopback allowed, securing across 127.0.0.1 Typically I don't make name references in the .conf profile, just accept / connect on related ports. This is the first time I recall ever pointing two VM's at each other. I have tried both service and gui on both Stunnel and VNC. Tried both application listing and discrete port listing in the server's windows firewall. I have tried updating security to the Admin account as owner or Administrators, in general. I have tried launching either or both as Administrator. When VNC client viewer calls to Server, Stunnel sees the connect, succeeds the Pem and stops. If I restart the stunnel service at the server, the viewer auth dialog suddenly succeeds. I question if this remains secured but clearly isn't practical for application. Both VM's are connected to me via RDP at the time, if this might relate to an Auth violation. I tried multiple VMs to eliminate anything related to a bungled VM config. I'm guessing there is some kind of circular routing restriction possibly. Citrix does use an X-window console to each VM on the control path, but in other instances there's never been any conflict. Not sure how to determine if the issue is config, Stunnel or OpenSSL or how to resolve it. Any suggestions would be appreciated. Regards and thank you again, Mike

verify=4
by oweijr oweirj 12 Aug '14

12 Aug '14

Hello, In the stunnel documentation, I see the following: level 4 Ignore CA chain and only verify peer certificate. My interpretation of level 4 was that only the server certificate had to be installed on the client in order for the cert verification to pass. No issuer/CA certificates were needed. However, when I do this, the connection fails. I see this following in the logs with verify=4: 2014.08.12 21:17:57 LOG7[26768]: Starting certificate verification: depth=0, subject=/C=US/CN=a.b.com 2014.08.12 21:17:57 LOG4[26768]: CERT: Verification error: unable to get local issuer certificate 2014.08.12 21:17:57 LOG4[26768]: Certificate check failed: depth=0, subject=/C=US/CN=a.b.com 2014.08.12 21:17:57 LOG7[26768]: SSL alert (write): fatal: unknown CA 2014.08.12 21:17:57 LOG3[26768]: SSL_connect: 14090086: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed My config file contains the following: verify = 4 CAfile = /opt/stunnel/certs/clients.pem chroot = /opt/stunnel setuid = stunnel setgid = stunnel pid = /run/stunnel.pid debug = 7 output = stunnel.log options = NO_SSLv2 cert = /opt/stunnel/certs/server.pem key = /opt/stunnel/certs/server.pem If I append the issuer certificate to the CAfile, after the peer certificate, then the connection is successful with verify=4. Is this expected behavior? Is there a verify level that works as I described above: only the peer certificate needs to be present, no CA/issuer certificates at all? Thank you for your help.

Um, there's just one little problem with this; what do you think about the attached public-domain patch that removes what looks very much like a stray quote character?

Windows Certificate Store
by j nasty 07 Aug '14

07 Aug '14

I haven't been able to get a definitive answer and can't find the information I need through traditional searching around. Anyways, is it possible to have sTunnel access the Windows certificate store to get the certificate that will be used for client authentication? If so, how can this be configured in sTunnel's configuration file? Or can you at least point me in the direction I can find the information I'm looking for? Many thanks in advance everyone!

Possible false positive trojan detection on stunnel-5.02-installer.exe
by Drew Mayo 06 Aug '14

06 Aug '14

Hi all, This is just an FYI. I'm a recent user of stunnel, and one of my team has just alerted me that f-prot (and unfortunately hence google drive) detects the current windows installer for stunnel 5.02 as a trojan. virustotal (which confirms it matches the sha256) tells me that the file is detected as: W32/Trojan.TDWH-2255 W32/Trojan3.JUA I've raised a misclassification request with f-prot, but of course that will probably take some time to get resolved. Of course, it is remotely possible it's not false, but i'm betting the other way. -d

More peer cert info export, new verify option
by Michal Vaško 05 Aug '14

05 Aug '14

Hello, for our current use-case we needed to add functionality to stunnel and therefore have made few patches. We distribute these patches with our software and were wondering what do you think about including them directly in stunnel. Firstly, we need peer certificate fingerprints in MD5, SHA1, SHA224, SHA256, SHA384 and SHA512. Patched stunnel exports all these in separate variables "SSL_CLIENT_*". Secondly, we could need subjectAltName values. Patched stunnel exports these in "SSL_CLIENT_SAN", but only rfc822Name, iPAddress and dNSName as we need only these. It could easily be expanded to all the values. Lastly, we required verification as if we first used verify = 2 and after failing trying verify = 4 (verify = 3 is technically verify = 2 AND verify = 4, if I am not wrong, and we need verify = 2 OR verify = 4). For this purpose my patch adds new verify = 5 option. I want to say that we did not just make all these requirements up, but we want to conform to RFCs describing NETCONF over TLS and its configuration. All the patches are included so you can go through them. Thank you. Kind regards, Michal Vasko
