How to start a process that won't end when my ssh session ends?

Somehow this isn't yielded by a google search.

I'm scripting a server in node.js. I start the server by executing its script with the node program:

node myserver.js

Have you tried GNU screen? Using it, a process can continue to run when you end your ssh session. nohup is a standard *nix command that will allow you to do the same, albeit in a more limited way.

Use screen. Type screen from the terminal and then launch your process. If you disconnect you can reconnect to the ssh session, by typing 'screen -ls' (to see active screens) and 'screen -r' to reconnect.

nohup is good to run the job under. If the job is already running, you can try disown -h (at least in bash)
