Accelerare le connessioni ssh con Controlmaster

Se si usa ssh versione 4 o superiore, si può velocizzare la filename completition o la connessione riutilinado le connessioni già utilizzate.

I set up the ControlMaster feature by adding the following lines to my ~/.ssh/config:

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

Note that the ControlPath expansion of the remote name (%r), host (%h), and path (%p) only works with OpenSSH 4.2 or newer.

To set up the master connection, run

ssh -M -S ~/.ssh/remote-host user@remotehost

Then, run ssh -S ~/.ssh/remote-host user@remotehost

for subsequent connections to the same host.
