Speed_up_SSH

About

Each time SSH connects it reauthenticates with the server, by using a socket it will only need to connect once then all the other connections will go through the socket. Its easy to setup and runs transparently improving connection speeds for multiple ssh connections.

Add the following 3 lines to your /etc/ssh/ssh_config:

 Host *
        ControlMaster auto
        ControlPath ~/.ssh/socket-%r@%h:%p

If you want to set this for a specific user, edit:

 Host *
        ControlMaster auto
        ControlPath ~/.ssh/socket-%r@%h:%p
