How do I kill a locked SSH session? [duplicate]

  • 772

From time to time, SSH sessions to my servers just freeze up and then neither Ctrl+C nor Ctrl+\ do anything.

How do I quit the session without just closing the Terminal it's in?

Clarification:

The session is locked as in, no keys are transmitted to the server. I'd like to shut it down gracefully, such that the user isn't logged in anymore.

I know I can kill the SSH client, but that will, in time, make the "2 users" info message I get from uptime meaningless. I'd like to know how many users are really logged in.

command-line

    A full list of escape codes can be found in the ssh manpage or by typing ~?.

  2. Type the following key sequence: Enter, ~, .. On US keyboards, the tilde (~) is Shift+`.
