SSH Tips

All changes are within file ~/.ssh/config

Multiple Connections

Often it’s useful to have multiple connections to the same server.

ControlMaster auto
ControlPath /tmp/ssh_mux_%h_%p_%r

Repeated Connections

If you find yourself making multiple consecutive connections to the same server then enablepersistent connections.

ControlPersist 4h

Passwords

If currently you type a password when making an SSH connection, you can make connecting much more pleasant by setting up SSH keys.

$ ssh-keygen
$ ssh-copy-id username@host.example.org

Hostname Aliases and Usernames

You can also define hostname aliases in SSH config, though this can involve listing each hostname. If your username on a remote server is different from your local username, specify this in your SSH config as well.

Host host1 host2 host3

   HostName %h.example.org

   User username
