echo 'Host * ServerAliveInterval 240' >> ~/.ssh/config && chmod 600 ~/.ssh/config
<CR>~. terminates the session.
I have a server that runs Ubuntu, and after a little while of inactivity, the
server would stop responding to commands. I have this bad habit sometimes of
ignoring a problem and accepting a half-solution (in this case I would just go
back to the session every so often and type
ls because that's always the
first thing I type in a terminal, regardless of whether I need it or not), but
seeing as how I'm an engineer who loves to solve problems, eventually I wisen
up and go for it.
So today I did a little bit of Google-fu and found a few Superuser/StackOverflow questions that had the solution (of course they did). First I found this, which was useful for learning that there is a way to terminate a frozen session (assuming that your SSH escape key is still the default, which if it isn't, then you probably already know this anyway).
So to terminate a frozen session, type
<CR>~. using Vim syntax where
is just Enter. I found that works, but it's not quite what I wanted.
So I found this which is basically everything I wanted, and you can tell
your client to send a heartbeat for a specific remote or all remotes, which is
what I did by adding the following to my
Host * ServerAliveInterval 240
And then I set permissions to
chmod 600 ~/.ssh/config to allow read by all.
Did you know you can use lazy references in markdown?

invisible and lets you have a named reference. Cool.
