Disabling IPv6
by Punitha 20 Apr '05

20 Apr '05

Hello Everyone !! I need to build Stunnel-4.09 in HP-UX11.11 without the support of IPv6. I did not use --enable-ipv6 option. In the configure log I could see the reference of getaddrinfo and getnameinfo functions. Is that refers any of the system file or the function defined in the souce code? I used `nm stunnel | grep getaddrinfo` and it shows the following. $ nm stunnel | grep getaddrinfo getaddrinfo | |undef |code | getaddrinfo | 118768|uext |stub | $ I need to confirm the source(from where they are taken) of getaddrinfo and getnameinfo functions. Is that related with the support of ipv6 in any way? Any of you please make me clear. Thanx in ADVANCE. Regards, Punitha.

Dear Users, Please stop reporting problems with obsolete versions of stunnel. You should always upgrade to the latest stunnel and OpenSSL first, than repeat your tests and report a problem. Best regards, Mike

Stunnel - Transfer loop executes not transferring any data.
by Michel Esber 19 Apr '05

19 Apr '05

Hello All, I am running a proprietary daemon on port 443 that accepts incoming connections. We are experiencing problems when activating stunnel on our production box. Everytime that we run our daemon with stunnel, our CPU and memory/swap area consumption is extremely intensive. Each stunnel process consumes approximately 37Mb of RSS memory. I have browsed through my logs and here is what I found: 2005.04.18 14:35:00 LOG3[15242:1245336]: transfer() loop executes not transferring any data 2005.04.18 14:35:06 LOG3[15242:1245336]: please report the problem to Michal.Trojnara(a)mirt.net 2005.04.18 14:35:06 LOG3[15242:1245336]: socket open rd=yes wr=yes, ssl open rd=yes wr=yes 2005.04.18 14:35:06 LOG3[15242:1245336]: socket ready rd=no wr=no, ssl ready rd=no wr=no 2005.04.18 14:35:06 LOG3[15242:1245336]: check_SSL_pending=0, ssl_closing=0 2005.04.18 14:35:06 LOG5[15242:1245336]: Connection reset: 258 bytes sent to SSL, 153319 bytes sent to socket Some details: a) My configuration file: [https] accept = 443 exec = /path/to/daemon execargs = daemon -ssl stunnel 4.07 on i686-pc-linux-gnu PTHREAD+POLL+IPv4+LIBWRAP with OpenSSL 0.9.6b [engine] 9 Jul 2001 Global options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH debug = 5 key = /usr/local/etc/stunnel/stunnel.pem pid = /usr/local/var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds b) glibc-2.2.4-31.7 glibc-devel-2.2.4-32.8 libcap-1.10-6 glibc-common-2.2.4-31.7 c) uname -a Linux myserver 2.4.9-e.57enterprise #1 SMP Thu Dec 2 20:45:51 EST 2004 i686 unknown d) gcc -v gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-118.7.2) e) openssl version OpenSSL 0.9.6b [engine] 9 Jul 2001 Can anyone shred some light?

stunnel generating defuncts
by Serxio Barral 19 Apr '05

19 Apr '05

Hi there! I'm using stunnel as client with SuSE SLES 8. Usually after several days working OK (up to two weeks) it begins to generate defunct processes for every transfer. At first, stunnel version was 3.14 (the one that comes out of the box with SLES 8), but now I have downloaded an compiled 3.26 and it just happens the same. killing stunnel won't help, since relaunching it again turns on generating defuncts. Situation does not come back to normal until rebooting the server. Any hint on this issue? Thanks in advance, Serxio Barral.

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.
