SSH Connection Sharing

Updated on
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. |
You’ll also need to create the sockets folder if you don’t have it already setup.
mkdir ~/.ssh/sockets
chmod go-w ~/.ssh/sockets
