Preventing idle SSH sessions from remaining connected is critical in keeping servers secure. Find out how to do this in a helpful tutorial.

If you're a Linux admin, you know the value of Secure Shell. Without this tool, you'd be hard-pressed to get much remote administration done on your servers. In fact, you probably SSH into and out of machines all day. Or, you might SSH into a server and inadvertently leave that connection up throughout the day.

And that, my friends, is inviting trouble.

What if you leave that connection up and running and someone happens by your desk while you're away. That someone could have a seat and have at your server. You do not want that. Or what if you have other users who secure shell into those servers, and you can't look over their shoulders all day?
