Does disconnecting from an SSH session kill it?

  • 772

I disconnect frequently by lag/timeouts or similar from a machine I am connected in to via SSH and I was wondering if my sessions are still active somewhere or if they close/logout after a certain time?

If they are not disconnected, is there a way to connect back in to the session?

(FYI, this is a default install/nothing funky... SSH is in default configuration).

    They timeout.

    If you want to change that behaviour you can use things like screen. Screen is essentially a terminal session that stays running. You can get disconnected and then just reconnect and attach to the screen session again. It's a bit daunting at first but it's pretty handy.

    I've personally found that adding -o ServerAliveInterval=30 to my SSH commands helps keep a connection alive but it won't help in cases of network interruption.
