Hi, (I'm not subscribed to the list, so please CC me on reply.) I'd like to request adding a feature to OpenSSH: Task: ~~~~~ It is quite sometime useful to invoke a program prior to connecting to an ssh server. The most common use case will probably be port knocking. That is a small program sends certain packets to a server and the server reacts to this by unlocking the ssh port, which

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

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config.

ssh client has the ability to set the destination of debug logs via the `-E` flag. ssh_config lacks an equivalent keyword to set the same option via configs. This patch follows the same semantics of other `*Path` type keywords and creates a new ssh_config keyword `LogPath`. [0] Bugzilla: https://bugzilla.mindrot.org/show_bug.cgi?id=3683 [1] GitHub PR:
