Stunnel 5.55 on Win 10 x64 GUI Mode
by Thomas Eifert 16 Jun '19

16 Jun '19

Tonight, I downloaded and installed Stunnel version 5.55 and installed it on Windows 10 x64 1903. If I run Stunnel as a service, everything works beautifully. No issues whatsoever. However, I just can't seem to get it to run in GUI mode. When I fire up the GUI, the configuration file loads fine with no errors. However, when attempting to establish any connection, the GUI simply crashes and the log file just terminates with nothing revealing: 2019.06.15 20:26:02 LOG7[main]: Service [ircs.3] accepted (FD=956) from 127.0.0.1:52874 2019.06.15 20:26:02 LOG7[main]: Creating a new thread 2019.06.15 20:26:02 LOG7[main]: New thread created 2019.06.15 20:26:02 LOG7[0]: Service [ircs.3] started 2019.06.15 20:26:02 LOG7[0]: Setting local socket options (FD=956) 2019.06.15 20:26:02 LOG7[0]: Option TCP_NODELAY set on local socket 2019.06.15 20:26:02 LOG5[0]: Service [ircs.3] accepted connection from 127.0.0.1:52874 2019.06.15 20:26:02 LOG6[0]: s_connect: connecting 154.35.138.250:6697 2019.06.15 20:26:02 LOG7[0]: s_connect: s_poll_wait 154.35.138.250:6697: waiting 10 seconds 2019.06.15 20:26:02 LOG7[0]: FD=1080 ifds=rwx ofds=--- (end of log) This is, of course, with the service stopped and de-installed. I've tried several remedies, including running Stunnel in compatibility modes, running it as an administrator, and I even tried to install it completely outside of the normal "program files (x86)" location. Also, the firewall is not the issue. Nothing seems to help. I can't figure out what on earth is occurring. Any insight/ideas would be appreciated.

Using STunnel4 with both SSL/TLS proxy AND PSK authentication
by Thomas Ward 14 Jun '19

14 Jun '19

Hi, all. We've got a specific use case where we need to implement an stunnel4 'tunnel' in the following format: Client <---> client-side stunnel4 <---> server-side stunnel4 <---> server The specific case for this is because of a server that does NOT support SSL on the remote side nor client side, and we need to use two stunnel4 instances to establish the "secure" tunnel. We can get it working with straight SSL/TLS certificates for a secure connection between the two but can't seem to add authentication to this, we want to get the stunnel4 on the client side and the stunnel4 on the server side to have to have some kind of authentication/exchange between them. Whenever we add the PSK options or client certs to the thing, we immediately get SSL/TLS problems, as it doesn't seem to support SSL/TLS handshakes properly at that point. Is there something I'm missing within the STunnel4 documentation about establishing the SSL/TLS tunnel AND adding an authentication component, or is this not possible? It doesn't currently seem possible based on my testing... Thomas

HELP! SSLv3 to TLSv1.2
by Eric Eberhard 07 Jun '19

07 Jun '19

Everyone, It goes to show that even after having used stunnel forever there is more to learn. I have a weird problem. A remote site that has always used SSLv3 wants to use TLSv1.2 - normally that takes 5 seconds in the config file. However, the remote site supplied the software that sends to them . and does not supply a version we can use unless we upgrade O/S and JAVA and who knows what else for hundreds of customers. In four days. Normally stunnel takes in clear text and sends it out in whatever you like (TLSv1.2 in this case). And the reverse. Can it take in SSLv3 and convert to TLSv1.2? Of course conceptually this is easy and just a logical extension of stunnel - in practice, if not there, it would be a job. Which I might tackle - but I first wanted to get community input. And if anyone wants to get paid to do this for me, we can talk :) Thanks All, Eric Eric S Eberhard VICS (Vertical Integrated Computer Systems) Voice: 928 567 3529 Cell : 928 301 7537 (not reliable except for text or if not home) 2933 W Middle Verde Rd Camp Verde, AZ 86322 Oh - help me out and please join this group.

Re: [stunnel-users] RE stunnel process owner

We use it solely on 100s of our customer’s Unix computers. My suggestion (that not everyone agrees with) is to run it under inetd. Unix does not function without inetd (or related like xinetd). You don’t have to start or manage a server. It is dead reliable and when processes die it cleans it up and so forth. You connect to localhost on some port, have a configuration that directs it to the right place, off to the races. I am not sure what you mean by container hardening. When connecting to localhost it never touches the network – the TCP/IP goes directly to the TCP/IP stack on the local machine. I am really sure I don’t know what check out is :) If you give me more info I can probably be of more use.

Questions/comments about the 64-bit installer.
by Thomas Eifert 25 May '19

25 May '19

I just upgraded to Windows 10 pro x64. I attempted to install Stunnel version 5.55b1. I made a couple of basic observations that I'd like to pass along. 1. The installer attempts to install Stunnel in the windows "Program Files (x86) directory. I thought Stunnel is now a 64-bit program. As such, why does it attempt to install in that directory? 2. The new version of Stunnel doesn't seem to want to run under Windows 10. If I attempt to run it as an app, the program terminates when I attempt to establish a connection and pass traffic through it. Running it as a service, it passes a few dozen bytes of traffic, then stalls. Changing compatibility modes had little effect. 3. Stunnel version 5.49 runs beautifully under Win 10. I'll continue to use it until i find a newer version that works. Has anyone else had similar experience trying to use Stunnel under Win 10? If so, I'd like to know if you were able to resolve these issues.
