I'd like a feature whereby ssh puts itself in the background after the first successful X11 (or other port) forwarding. The reason for this is simple: error handling. If the application fails to open the X display and exits, then the client can still exit with the application's exit code. But if the application opens the X display successfully, then it can just display any errors by

Hi, In file ssh.c, in function "ssh_session2", this piece of code: /* If requested, let ssh continue in the background. */ if (fork_after_authentication_flag) if (daemon(1, 1) < 0) fatal("daemon() failed: %.200s", strerror(errno)); implements the "-f" option, but when run from cron, it does not detach properly because of the second parameter (noclose) of the daemon() function. The result is a defunct process and a CR...

Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by

Hi, I have a problem with a Linux box which I updated from 2.5.2p2 to 2.9p2 recently. It's running a tunnel started via inittab using a script which starts ssh -2 -N -o 'ConnectionAttempts 3600' -L <tunnel> $host This has run reliable with 2.5.2 over the last months. Now, after I have upgraded to 2.9p2, the tunnel is closed right after each attempt of an application to use
