stunnel 4.x.x and IRIX
by Eric Haddix 31 Jan '06

31 Jan '06

I happened upon a user here that posted a couple of months ago(I think) who used IRIX and had successfully compiled stunnel. Any chance you're still around!?!? I get one of two things. Before I apply the patch, it will crash right after startup. No logs, just dumps core. After the patch, it starts and exits immediately. I can run it with -version, etc. and it seems to work fine. Anyone had this and/or know what can be done? Eric

FQDN validation and checking within STunnel
by Nagasundaram, Sekhar 31 Jan '06

31 Jan '06

All: Is there a setting in Stunnel to do FQDN checking? Level 3 checking requires a local copy of the Peer's certificate. When doing mutual authentication, I run into scalability issues when the devices Run into the thousands using Level3 validation. However, if Stunel was capable of doing FQDN checks, That would help while not requiring me to do level 3 checks (although that is probably better). Thanks Sekhar

stunnel errors on Solaris
by Kevin Mooney 27 Jan '06

27 Jan '06

Hello All, I am having some errors on a Solaris 8 machine with stunnel. Everything seems to be working fine, but I am just a little leary since it is under security violations. I couldn't get anything from google using the string Too many retries on SSL shutdown. I was curious if anyone has seen this before or if somebody might have an idea as to what this means. Thank You, Kevin Security Violations =-=-=-=-=-=-=-=-=-= Jan 26 14:38:24 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11151]: Too many retries on SSL shutdown Jan 26 14:38:24 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11151]: Too many retries on SSL shutdown Jan 26 15:28:19 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11180]: Too many retries on SSL shutdown Jan 26 15:28:19 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11180]: Too many retries on SSL shutdown Jan 26 14:38:24 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11151]: Too many retries on SSL shutdown Jan 26 15:28:19 duvel stunnel: [ID 821868 daemon.notice] LOG5[23863:11180]: Too many retries on SSL shutdown

Stunnel and Forte Agent
by Malcolm William Mason 27 Jan '06

27 Jan '06

Hello to all, I have been using Stunnel to access News Groups at ATT.net to by-pass or tunnel through ATT's SSL for some time. I have run into trouble and I am getting a message "connection" failed. At first I thought that it was Stunnel and after deleting and re-installing Stunnel, I an getting the same RESULT. Was there an older version of Stunnel that worked and will the new, updated Stunnel not work or does it need to have some settings changed? Malcolm Mason MWM1(a)jhu.edu

Proxy Support and 4.15b2
by Ben Green 26 Jan '06

26 Jan '06

Greetings everyone, I have been working for a few days with Stunnel and have been trying to get it working with the proxy servers that filter all outbound traffic at work. I stumbled across 4.15b2 today and was able to get it all to work well to SSL enable telnet and fix through the connect protocol. I plan to use this in production if all goes well in dev, test, and qa over the next 2 months. I was not around on the list when the announcement went out for 4.15b2 on November 16th (found it in the archives). I'll get to my point, now. I am wondering how testing is going with 4.15b2. Is it going to be released as 4.15, soon? Has anyone put 4.15b2 in a production situation? Thanks. Ben Green

Re: [stunnel-users] exclusively TLS
by Jesse Small 24 Jan '06

24 Jan '06

I've been working through the same problem as John, but I tried using Jan's solution by setting the options and still haven't been able to get it to work. On server1 I am running openssl s_server with tls-only specified: openssl s_server -accept 8443 -cert XDS_REG_HXTI.cer -key hxti1.key -tls1 On the client side (server2), I have stunnel set up as a client listening on localhost port 8100, and forwarding over to server1, port 8443. Then to test I run 'telnet localhost 8100' and see the error message from s_server: ACCEPT ERROR 16656:error:1408A10B:SSL routines:SSL3_GET_CLIENT_HELLO:wrong version number:s3_srvr.c:683: shutting down SSL CONNECTION CLOSED In my stunnel.log file I can see this error message: SSL_connect: 14094410: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure So to me it still seems to be sending out a client hello in sslv3, despite my efforts to the contrary. Below are the pertinent parts of my stunnel_client.conf file. Any help you could give would be greatly appreciated. Thanks, Jesse ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS options = NO_SSLv2 options = NO_SSLv3 [toOtherServer] accept = 8100 connect = devapp:8443 -----Original Message----- From: Jan Meijer [mailto:[email protected]] Sent: Friday, January 20, 2006 5:20 PM To: Moehrke, John (GE Healthcare) Cc: stunnel-users(a)mirt.net Subject: RE: [stunnel-users] exclusively TLS On Fri, 20 Jan 2006, Moehrke, John (GE Healthcare) wrote: > It is not the list of ciphers that I want to choose from.

Ah, that way. options = SSL_options OpenSSL library options The parameter is the OpenSSL option name as described in the SSL_CTX_set_options(3ssl) manual, but without SSL_OP_ prefix. Several options can be used to specify multiple options. For example for compatibility with erroneous Eudora SSL implementation the following option can be used: options = DONT_INSERT_EMPTY_FRAGMENTS Check the SSL_CTX_set_options manpage, it says -amongst other things-: SSL_OP_NO_SSLv2 Do not use the SSLv2 protocol. SSL_OP_NO_SSLv3 Do not use the SSLv3 protocol. SSL_OP_NO_TLSv1 Do not use the TLSv1 protocol. That ought to do the trick I'd say. Let us know if it did :) Jan -- http://www.surfnet.nl/organisatie/jame

https to http proxy is buggy with IE
by Glen 22 Jan '06

22 Jan '06

Hi Everyone, I am trying to use stunnel to do the ssl portion for the web server. Mainly because the certificate I have is easy to setup in stunnel (was originally created for an openssl based serer) and the web server supports it's own propriatery cert format which I would like to avoid having to convert to. I have it working fine with all browsers except for the buggy Internet Explorer. With internet explorer anything requiring a page redirect fails (from viewing the logs it appears the socket gets closed before the redirect is finished resulting in a blank page being sent to the browser. I have tried the TIMEOUTclose = 0 but that hasn't helped. Any suggestions? thanks, Glen
