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.

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.
