SSH Escape Sequences — Escaping the Frozen SSH Connection

Dev tip 8/99

Ever have an SSH connection to a remote server freeze because the internet died or you switched from wifi to wifi? In the past I would shut down the terminal window and create a new one because I lost control of the one with ssh. Then I found out about the ssh escape sequence ~.. When ssh freezes, now I type the sequence <return>~. and I regain control of my terminal. That sequence forces SSH to disconnect from the server!

Check out the man page (ubuntu) for more information.
