[sf-lug] sftp

[Alex Kleider]

As I understand it, scp and sftp are subsystems of ssh.
SSH can be configured to listen on a non standard port.
The ssh and the scp client commands allow for this with the -p and -P options respectively.
How does a client establish an sftp connection with an SSH server listening on a non standard port? 
Yes I know the contempt many have for "security by obscurity" and I respect the arguments supporting these sentiments BUT given that the situation is as it is, it's hard for me to imagine that there isn't an answer to this puzzle.
Does anyone happen to know what it is?
