...dd a new remote forwarding or ssh -S ~/.ssh/ctl -O cancel-rforward localhost:2000 localhost to remove it. The patch is against openssh-SNAP-20050302 so the new fine tuned forwarding code is already contained. While working on the patch a few questions/inconveniences have emerged: 1) why is mux_command in ssh.c not part of Options? 2) the current implementation allows -O to occur only once. So, to add or remove multiple channels ssh has to be called multiple times. Would it make sense to extend the code to allow it to occur multiple times? ssh -S ~/.ssh/ctl \ -O add-rforward 2000:forw...

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
