RE: [stunnel-users] Vista not connecting to port 139

Alaric: This is strange. When I go to the Security Center, it says the McAfee Personal Firewall is on, but I can't find it in the Start menu, Services, or anywhere else. Any ideas?

Ok, nothing to do with any of that. Deep inside OpenSSL, there is a call to gmtime_r. Deep somewhere in hell (I hope), someone decided that LynxOS' gmtime_r functions would have its arguments *reversed*. REVERSED. I guess they were going for SIXPO complience. So that call would write rubbish in the stack, hence no returning from the call and segfault instead. So, nothing to do with stunnel after all. Thanks for the support anyway! :) Y. - TGIFriday

[PATCH?] Senting a list of accepted CAs to the client
by Miloslav Trmac 27 Apr '07

27 Apr '07

Hello, stunnel currently does not send a list of accepted CAs, see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=327001#c20 . Sending the list was #if 0-ed out sometime between stunnel 3.22 and 4.00, with no change log entry AFAICS. Does anyone remember know why was it disabled, and whether it is safe to reenable (e. g. using the attached patch)? Thanks, Mirek

Stunnel with Goldmine 6.70.61214

Greetings! Use Goldmine with Gmail domain services. Have set up according to Mike Casteel's instructions. However, Goldmine will not download email from the Gmail (the GMail address: rayrandall(a)ethosadvisory.com).

Connecting via rtmps to Red5 server
by David Schulberg 25 Apr '07

25 Apr '07

Hi, I have been led to stunnel as the way to get a Flash application to communicate securely with Red5 server. Red5 doesn't directly support ssl connectivity but using rtmps protocol (rtmp tunnelled via https) clients should be able to connect to Red5 if stunnel handles the encrypted traffic on port 443 and passes unencrypted communications back and forth to the Red5 on a port it expects to receive rtmp communication.. (refer http://www.adobe.com/devnet/flashcom/articles/firewalls_proxy04.html) The log file I get when I attempt to talk rtmps is shown below 2007.04.25 18:19:04 LOG7[3932:3384]: New thread created 2007.04.25 18:19:04 LOG7[3932:3664]: https started 2007.04.25 18:19:04 LOG7[3932:3664]: FD 224 in non-blocking mode 2007.04.25 18:19:04 LOG7[3932:3664]: TCP_NODELAY option set on local socket 2007.04.25 18:19:04 LOG5[3932:3664]: https accepted connection from 127.0.0.1:1249 2007.04.25 18:19:04 LOG7[3932:3664]: FD 248 in non-blocking mode 2007.04.25 18:19:04 LOG7[3932:3664]: https connecting 127.0.0.1:1935 2007.04.25 18:19:04 LOG7[3932:3664]: connect_wait: waiting 10 seconds 2007.04.25 18:19:04 LOG7[3932:3664]: connect_wait: connected 2007.04.25 18:19:04 LOG5[3932:3664]: https connected remote server from 127.0.0.1:1250 2007.04.25 18:19:04 LOG7[3932:3664]: Remote FD=248 initialized 2007.04.25 18:19:04 LOG7[3932:3664]: TCP_NODELAY option set on remote socket 2007.04.25 18:19:04 LOG7[3932:3664]: SSL state (connect): before/connect initialization 2007.04.25 18:19:04 LOG7[3932:3664]: SSL state (connect): SSLv3 write client hello A 2007.04.25 18:24:04 LOG6[3932:3664]: init_ssl: s_poll_wait timeout 2007.04.25 18:24:04 LOG5[3932:3664]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.04.25 18:24:04 LOG7[3932:3664]: https finished (0 left) The stunnel.conf file has the following settings that pertain specifically to this situation client = yes [https] accept = 443 connect = 1935 What I seem to see (according to the logfile) is that an ssl connection is successfully established but no subsequent communication takes place after the connection has been made. At this point my Flash application doesn't send any messages via the ssl connection which seems to implicate my client as being the source of my problem. I would appreciate any advice on how I can best investigate this whole situation to resolve the issue. Regards, David Schulberg email: davids(a)evertech.com.au
