SSH Connection Sharing 2020-06-05T16:39:24-04:00 false

If you're like me, you open a lot of different terminal sessions throughout your day. When it comes to SSH, I want these different sessions to share a connection rather than creating a new one each time.

To accomplish this, I have the following in my ~/.ssh/config file.

ControlMaster auto
ControlPersist no
ControlPath ~/.ssh/sockets/socket-%r@%h:%p
Option Description
ControlMaster Allows connection sharing
ControlPersist yes to keep connection up even when no clients are connected.
2s (or custom timeout) to keep the connection up for 2 seconds after no clients are connected.
no to disconnect immediately
ControlPath Where to store connection information. This should not be writable by other users.
