How to keep your gnome-terminal from hanging in SSH connections

I've been having problems with my GNOME terminal hanging when on an extended SSH connection. Finally realized today there's probably a keepalive configuration somewhere.

There is.

Go into your ~/.ssh/config file and add this stanza under your Host config:

  ServerAliveInterval 240

(note the two spaces to make it a sub-property of Host)

If you want every SSH connection to stay alive, add the rule for every host

Host *
  ServerAliveInterval 240


  1. Why isn't this the default?

    Really? You're using a Linux environment and you're asking why the default isn't "Don't just break?"
