Restore access to hung SSH session
It is common problem of hung SSH session and having to close and reopen your terminal/putty. Use the following escape-char to quit your hung SSH session and get your shell back.
[ENTER] ~.
Escape Characters
When a pseudo-terminal has been requested, ssh supports a number of functions through the use of an escape character.
A single tilde character can be sent as ~~ or by following the tilde by a character other than those described below. The escape character must always follow a newline to be interpreted as special. The escape character can be changed in configuration files using the EscapeChar configuration directive or on the command line by the -e option.
The supported escapes (assuming the default '~') are:
~.Disconnect.~^ZBackground ssh.~#List forwarded connections.~&Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate.~?Display a list of escape characters.~BSend a BREAK to the remote system (only useful for SSH protocol version 2 and if the peer supports it).~COpen command line.
