Several connections on a short period of time problem
by Teigao, Rafael Coninck 16 May '07

Hi, I'm running Stunnel 4.20 to connect a Win client to a Win server. On the server it runs as a service, but on the client side I call it every time a connection is requested with a different config file (I need dynamic configuration) If I connect, disconnect and connect again very quickly (say, in 10 seconds), the fourth time (usually) that I try to connect will give me error 10060 (timeout) on the client application (not Stunnel). Does Stunnel restrict the amount of connection from the same client based on time or something like that? Thanks, Rafael.

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
