Hi there,

okay so I have a port knocker installed on my remote server so I am trying to bundle a bunch of directories in a single ssh session that rsync establishes. so far all the rsync examples I have seen require a new ssh session for each directory.

is there anyway to get something like this into one line and therefore one ssh session. Clues on this?

Try the ControlMaster=auto option to SSH with an appropriate ControlPath setting.

Example of usage at: (Googled: SSH multiplex)
http://www.linuxjournal.com/content/speed-multiple-ssh-connections-same-server

As an '-e' argument, it'd be:

-e 'ssh [...etc...] -o ControlMaster=auto -o ControlPath=~/.ssh/master-%r@%h:%p 
[...etc...]'
