I thought that I’d enter a quick post tonight about quickly and easily terminating a stuck or frozen ssh terminal. Most people know these keystrokes, so this is geared towards those new to linux and ssh.
If your session is stuck, to terminate the ssh session, type these keystrokes separately:
"Enter" , "Tilde(~)" and "Period(.)"
These three simple keystrokes should then terminate your current ssh session.
To be more adventurous, if you keep ssh sessions open to systems outside your network, you can use autossh with screen. Will cover this in another post
