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.
