Keep ssh alive

Due to our load-balancing router being a little “harsh” on closing connections that appear to be unused, ssh often sits and hangs.

Using a standard ssh config option though we can set a server keep-alive (on the ssh client, which also keeps sshfs alive)

In the “~/.ssh/config” file, simply adding the following keeps the connection sending a small packet every 30 seconds :- ServerAliveInterval=30

I’m sure windows clients like puTTY also have a similar option, and on a mac, it should be the same file as Linux.
