...annot bind to port: 5000' was written to the syslog, but the connection still persisted. I had no way on the client side to know that the listening wasn't taking place. that is, the portforwarding of port 5000 failed, but the ssh connection on port 22 was still there. I found the spot in serverloop.c, where it seemed to be ignoring the return status from the 'channel_setup_remote_fwd_listener' call. The fix for me was a simple testing of the success, and calling fatal() to indicate that the port forwarding failed. Here is the patch: --- serverloop.c.orig Sat Feb 22 11:35:39 2003 +...

...orms not supporting the concept of "privileged" ports only accessible by privileged users but which allow everyone to use these ports. This patch removes some Cygwin dependencies from the code. Otherwise, if this patch isn't applied, we definitely need another #ifndef HAVE_CYGWIN in serverloop.c otherwise serverside port forwarding for reserverd ports doesn't work in Cygwin's 3.4 version. The official Cygwin release of 3.4 contains that additional HAVE_CYGWIN patch so far. Corinna Index: acconfig.h =================================================================== RCS file:...

...to that pty. The problem can be reproduced by connecting to the localhost host via ssh using protocol version 2, and then killing the ssh client with a SIGKILL. The sshd server notices the connection closing and exits, but does not update /etc/utmp. I believe the problem is in server_loop2() in serverloop.c. When the ssh connection is terminated abruptly, one falls out of the input processing loop and tries to clean up. There is a loop that "wait"s for child processes to die, and terminates the associated sessions. Unfortuately, the "wait" uses the WNOHANG flag, so any session...

Hi openssh-unix-dev subscribers :) I have found that ServerAliveInterval & ServerAliveCountMax have some bug. Basically the ssh-alive check function (that verify the peer is alive) is called only if no data at all gets into ssh (when it should work only for server channel).I am pretty sure developers know about this ..anyway I have tried to fix this issue.
