Supporting ssh multiplexing

[NobodyXu]

In my local ~/.ssh/config:

Host *
    ControlMaster auto
    ControlPath /tmp/ssh-%r@%h:%p.socket
    ControlPersist yes
    ServerAliveCountMax 2
    ServerAliveInterval 120

I enabled ssh multiplexing for any connection, but rtop seems not to be using the ControlPath.

Is it possible for rtop to use the ControlPath opened by ssh?
