syslog question
by Brian T 04 Mar '05

04 Mar '05

If debug=4 ( or not 0 ) and output= is commented in an stunnel config, it looks like in server mode, messages goto syslog. But in client mode, nothing goes to syslog. Is this the way it's supposed to be? -Brian

Re: [stunnel-users] long delay to close the ssl session ?
by ikeda＠areabe 04 Mar '05

If TIMEOUTclose value is positive, stunnel does not transmit TCP FIN, even though application sends TCP FIN, until timeout time expires I don't know why stunnel designer chose it, maybe because of the performance, or some others. Some of the browsers do not start to display the page until receiving the entire packet. And one of the trigger for the browser to detect to receive the whole is TCP FIN. From that things, such kind of the problem of yours occurs. regards taka On Fri, 4 Mar 2005 10:39:47 -0800 (PST), gary ng <garyng2000(a)yahoo.com> wrote: > Thanks, that did the trick.

long delay to close the ssl session ?
by gary ng 04 Mar '05

04 Mar '05

Hi, I am using stunnel to wrap SSL around SWAT. Everything works fine except that it takes a very long delay for the browser to see that the page has already been transmitted completely(in other words, the other end has closed). I observed this behaviour with both 3.x and 4.x stunnel. Looking through the log, I see that it takes exactly one minute from the start of the session till the session is closed, seems to be some parameter within stunnel to hold the session. I tried both inetd as well as stand alone stunnel mode and both behave the same as well. Is this an issue with SWAT or stunnel ? If I just use plain SWAT through inetd, I don't see this behaviour. thanks for any help in advance. gary __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

compilation errors

Anyone here managed to build stunnel for Irix? it seems socklen_t is undefined as a type on this OS (and also older versions of solaris). I have found a possible solution here: http://sprg.ssl.berkeley.edu/~fastops/ITOS/portable/socklen$_t.html but I need to know what type this identifier is supposed to be. any help?

Naive question: will stunnel connect dynamically?
by Duncan Murdoch 02 Mar '05

02 Mar '05

I currently use openssh to open a tunnel between my laptop and my POP3 server, but the tunnel keeps locking up. (I think it's a server problem, or an intermittent line problem, because it happens with both openssh and Putty.) What I'd like is a program that would open the tunnel only as needed, so I can get the mail, and let the tunnel close. Can stunnel do this? More generally, is there a quick summary somewhere on the relative benefits of stunnel's use of SSL versus an SSH approach? Duncan Murdoch

Windows XP Pro as a client of Remote Dekstop via stunnel
by Jacek Baszkiewicz 02 Mar '05

02 Mar '05

Hi! I'm currently working (without success) on such problem: I have to connect via Stunnel to Windows Server Remote Desktop from workstation with Windows XP Proffesional. When I refer to the local port handled by stunnel, Windows doesn't let me go go further, because it thinks that I'm trying to use local Remote Dekstop and prints: "You are already connected to this machine" (there can be only one connection through RD) . Is there any workaround for this problem, namely, to use secure connection via Stunnel to Remote Dekstop on XP Pro client? This is my config: client=yes cert = stunnel.pem [ts] accept=localhost:3389 connect=remote_ip:443
