Please Help! I keep getting the same error.
by Theodore W. Hildebrandt 11 Apr '05

11 Apr '05

Refer to my submission of 03/24/05: "error:1408F10B:SSL . . . " I had hoped that someone would tell me how to get around this error, but no message has appeared in the stunnel Archive. I have now ftp'd version 4.09 and tried it, with the same results. I wait and wait for a connection, and finally interrupt the process, since it's not going anywhere. And then I get the "error:1408F10B. . ." message in the stunnel log. Since I seem to be able to send e-mail from my old Pentium II computer (Windows 98SE) I'm, using it so send this message. [Note that I can still receive e-mail on the new Dell Pentium IV machine (Windows XP Home). I just can't send anything.] Doesn't anyone have answers? Ted Hildebrandt

Unexpected closed connections
by Rory Campbell-Lange 11 Apr '05

11 Apr '05

Hi Everyone We have been very happily using stunnel for about 5 months connecting a site office back to a main office, tunnelling imap connections. We are suddenly seeing lots of disconnection messages and people at a. can no longer see their mail on d. The server suffers a "socket write shutdown" condition and shuts down the associated process. We have restarted the routers and firewalls and all seems to be working fine, other than stunnel. I'd be grateful for any insight or further help. Many thanks Rory Present arrangement: a. site client | b. site server port forwarded to c. | | internet | | c. main office server port forwarded to d. | d. imap server Server b forwards imap connections securely to the main office server, which then passes on on the imap connections to the imap server. Server b connects through the following inetd line: imaph stream tcp nowait nobody /usr/sbin/stunnel /usr/sbin/stunnel -c -r server_c_address:imap We are running version 3.26 on debian: stunnel 3.26 on i386-pc-linux-gnu PTHREAD+LIBWRAP with OpenSSL 0.9.7e 25 Oct 2004 Server shows following disconnect messages: 2005.04.11 13:21:46 LOG7[13320:163848]: SSL alert (read): warning: close notify 2005.04.11 13:21:46 LOG7[13320:163848]: SSL closed on SSL_read 2005.04.11 13:21:46 LOG7[13320:163848]: SSL alert (write): warning: close notify 2005.04.11 13:21:46 LOG7[13320:163848]: SSL write shutdown (output buffer empty) 2005.04.11 13:21:46 LOG7[13320:163848]: Socket write shutdown (output buffer empty) 2005.04.11 13:21:46 LOG5[13320:163848]: Connection closed: 92 bytes sent to SSL, 0 bytes sent to socket 2005.04.11 13:21:46 LOG7[13320:163848]: 10.0.0.24.imap finished (6 left) Client logs: Apr 11 15:50:26 hald stunnel[4672]: server_b.imaps connected from 10.0.1.54:49301 Apr 11 15:55:05 hald stunnel[4672]: SSL_connect: Peer suddenly disconnected ...

stunnel 4.09 error message-- s_poll_wait:invalid argurment <WSAEINVAL> <10022>
by Ed Huckins 10 Apr '05

10 Apr '05

Occurs when I upgraded from stunnel 4.08 to 4.09. Using OpenSSL 0.9.7f . Stunnel.conf looks like # We're running as a client to SSLify the POP & IMAP connections client=yes # POP3 service, listens on localhost:11110 [dslx-pop3s] accept=localhost:11110 connect=mail.dslextreme.com:995 What do I need to add when going from 4.08 to 4.09? Everything seems to work; just a reset of the connection occurs instead of a close. --- avast! Antivirus: Outbound message clean.

stunnel and NNTP on windows - best practices
by Sir Thanksalot 08 Apr '05

08 Apr '05

Hi all, I am trying to use stunnel for SSL access to a NNTP newserver and found quite a few pages that list ways of doing that. I personally am using xnews as my newsreader, and I have seen variations of the same instructions with different software (Agent, Free Agent for newsreaders, Pegasus Mail as your mail application etc.). For completeness sake, here are some of the ones that I've found - http://www.cotse.net/users/putty/ssl (for Xnews and stunnel 4.x) http://www.geocities.com/d4vidb/x_setup13.html (for Xnews and stunnel 3.x - doesn't use the stunnel.conf file necessary in stunnel 4.x) http://www.noderunner.net/~llin/old/nntp-ssl.html (for a newsreader and stunnel 3.x. It also has links to a stunnel.conf file for stunnel 4.x users) In all these instructions (whether using the stunnel 3.x commandline options or using the stunnel.conf file for stunnel 4.x), I haven't seen any instructions about creating any certificates or public/private keys or a passphrase. Also there doesn't seem to be any writeup on what algorithm actually ends up getting used or even a way to pick which algorithm to use. What's the best practise for users? Should they do anything extra? Set up key pairs? Choose a default algorithm? Thanks. -- _______________________________________________ NEW! Lycos Dating Search.

TIMEOUTclose
by Joe Abbey 08 Apr '05

08 Apr '05

Background: I have been having issues getting Entourage to connect with my mail server over POP3S. Entourage will connect, communicate, and then hangs for 60 seconds. According to tcpdumps, Entourage appears to hang until a timeout. Connecting directly to the pop3 daemon, bypassing stunnel, there is no lag. Therefore something appears to be wrond with the stunnel/Entourage interaction. To get Entourage to work with POP3S and have virtually no lag, I've set in my stunnel.conf TIMEOUTclose = 2 for [pop3s]. Question: Is there any reason not to set TIMEOUTclose = 0? Thanks! Joe

Compilation error on windows, cannot find "-lssl"
