How to Kill an Unresponsive SSH Session, and other useful escape sequences

I always forget how to do this.

[newline] ~ .

That's enter key, tilda, then period. Presto, back to your friendly (local) console.

Here are a few more useful escape sequences, straight from man ssh (note that all must be preceded by a newline character):

The supported escapes (assuming the default ‘~’) are:

 ~.      Disconnect.

 ~^Z     Background ssh.

 ~#      List forwarded connections.

 ~&      Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate.

 ~?      Display a list of escape characters.

 ~B      Send a BREAK to the remote system (only useful for SSH protocol version 2 and if the peer supports it).

 ~C      Open command line.  Currently this allows the addition of port forwardings using the -L, -R and -D options (see above).  It also allows the cancella‐
         tion of existing remote port-forwardings using -KR[bind_address:]port.  !command allows the user to execute a local command if the PermitLocalCommand
         option is enabled in ssh_config(5).  Basic help is available, using the -h option.

 ~R      Request rekeying of the connection (only useful for SSH protocol version 2 and if the peer supports it).

Nod to this guy, whose site I've always wound up at when I'm trying to remember this.
