Loss of ability to use Stunnel-Blat, and a solution
by Roger Bohl 10 Jul '18

10 Jul '18

Early in 2018, around the time when I upgraded my system to Windows 10, the Stunnel and Blat files that had worked fine with my Vista PC would not work with the new PC. However, the "bug" turned out to be unrelated to the change in operating systems, but rather an "upgrade" to Gmail: Coincidentally, about that time, Gmail evidently decided to stop accepting e-mails from apps deemed "a less secure app", including Stunnel-Blat, with Blat then displaying messages: *** Warning *** The SMTP server did not accept Auth PLAIN value. *** Warning *** Are your login userid and password correct? *** Warning *** The SMTP server did not accept Auth LOGIN PASSWD value. Only a failure message sent to my "backup e-mail address" led me to explore this as a possible cause for what I had thought was, but turned out not to be, a Stunnel-Blat problem. Gmail has an option to suppress this heightened security feature, and when I activated this option, my Stunnel-Blat tools immediately began to function as intended. While I was at first able to enable Gmail to "Allow access from "less secure accounts," I have been unable to get through Gmail options consistently to turn this on and off and share this info with others. (I would welcome instructions that work consistently.) I would also welcome guidance on how to include Stunnel-Blat as a specific alllowed app, without having to enable Gmail to enable *all* "less secure apps" Roger Bohl

Re: [stunnel-users] Intermittent error in 042_inetd
by Eric S Eberhard 10 Jul '18

The 50% could be because the server side is not fully updated - we have this problem a lot with very large companies that should know better (and in reality should overlap instead of changing over - meaning allow SSLv3 for 3 months or something while also accepting TLSv2. A very good way to test is to get a telnet program. Then "telnent localhost port#" - the port # being the port number stunnel is running on. This will remove all variables except stunnel and allow you to see the output. It could be you are connecting fine and failing some other authentication like a login - which you can see often with telnet. And set your firewall to not allow telnet on port 23. Also, we have found stunnel MUCH more reliable under inetd (if you are on Unix of course) than as a stand-alone server. A little performance loss that is unnoticeable to us - big customers exchange 2-4 million XML documents a day (using stunnel) so inetd is definitely not the most efficient way, but the machines are so darn fast it seems not to matter. The certificates have become more painful but I have never had to use an official signed one. I make my own with openssl. However, there are intermediate ones that are needed from whomever you connect to if they have a signed certificate - say from Verisign - you may need your certificate and Verisigns, etc - in a chain. I use "cacert" to set to a large file of .pem certificates - which I simply download from the Web (available all over, some work, some don't. When you get one that works . then use it. You can modify them by adding anything not found in the file. Supposedly the cacert file I have now is good till 2020 for the big names. You can also use openssl to get the certificate from the server - just ask and you shall receive. It should have the entire chain. I used to have on massive cacert for everyone and it was getting out of hand. As tacky as it is, I just make a cacert.pem file for every connection (e.g. Walmart, Fedex, Target, whatever). This allows working connections to keep working while you fiddle with a tricky one.

I should also point out that the cipher suite is related to openssl version stunnel is compiled with. Again, we had customers that connected with TLSv1.3 and then could not negotiate a cipher suite ... leading to lost connection. Make sure you update openssl first -- then compile stunnel.

Stunnel connection issue?
by Spies, Will 09 Jul '18

09 Jul '18

I've been trying to get Stunnel to work for some time now. I have avoided using the mail list - but I see no recourse now. I think I've tried just about every setting I could find. I appear to be getting a connection issue - but as you will see the log just doesn't indicate clearly what is going on. The behavior is my client is failing to get a connection through Stunnel to my backend. The log appears to be closing a socket (but can't tell which one frontend or backend). Nothing wrong happens up until a client connects - 443 binds fine and later a connection to my backend 554 appears to connect find. If someone/anyone can help direct me to how to trouble shoot this better I would greatly appreciate it. As you will see in the log - the client attempts twice to get through. An excerpt of my log and the conf is below. /etc/stunnel.conf: socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 output = /var/log/stunnel.log debug=7 [rtsp] cert = /etc/stunnel/stunnel.pem

Intermittent error in 042_inetd

Afternoon, Until recently we'd disabled `make test` because of certificate problems - we've re-enabled it (using `make check`) but are getting intermittent failures (around 50% of CI runs). Below is the output from the logs - I can't see what's gone wrong, can anyone shed any light? 2018.07.04 09:59:36 LOG7[ui]: Clients allowed=14648 2018.07.04 09:59:36 LOG7[ui]: errno:

stunnel on Windows - using CAPI - tls v1.2?==?utf-8?q? ?
by Brian Ipsen 04 Jul '18

04 Jul '18

Hi Does anyone know whether there is a fix pending for being able to use the Windows built-in certificate store (by CAPI) for client authentication - and using TLS v1.2 ? Currently I need to force the stunnel client to use TLS v1.1, as there seem to be a limitation somewhere if using TLS v1.2... Regards Brian

Hi, We are using stunnel to allow us to punchout to suppliers using TLS 1.2 protocol. We are seeing the following with this particular supplier. 2018.07.02 08:49:05 LOG6[4]: TLS connected: previous session reused 2018.07.02 08:49:05 LOG6[4]: TLSv1.2 ciphersuite: ECDHE-RSA-AES256-SHA384 (256-bit encryption) 2018.07.02 08:49:05 LOG7[4]: Compression: null, expansion: null 2018.07.02 08:49:15 LOG3[4]: SSL_read: Connection reset by peer (131) 2018.07.02 08:49:15 LOG5[4]: Connection reset: 1720 byte(s) sent to TLS, 0 byte(s) sent to socket 2018.07.02 08:49:15 LOG7[4]: linger (remote): Invalid argument (22) 2018.07.02 08:49:15 LOG7[4]: Remote descriptor (FD=13) closed 2018.07.02 08:49:15 LOG7[4]: Local descriptor (FD=3) closed 2018.07.02 08:49:15 LOG7[4]: Service [dell-https] finished (0 left) We have set socket = l:SO_LINGER=1:60, but still occasionally have an issue.
