Useful escape sequences for SSH and Telnet that I always forget.

SSH

~ is the escape character for ssh connections for the standard ssh client. Supported escape sequences:

• ~. — terminate connection (and any multiplexed sessions)
• ~B — send a BREAK to the remote system
• ~C — open a command line
• ~R — Request rekey (SSH protocol 2 only)
• ~^Z — suspend ssh
• ~# — list forwarded connections
• ~& — background ssh (when waiting for connections to terminate)
• ~? — this message
• ~~ — send the escape character by typing it twice

(Note that escapes are only recognized immediately after newline.)

Telnet

Ctrl-] is the escape character for connections with the standard telnet client.
