Re: How does screen survive logout?

[David Thomas]

My understanding (not having looked at the code - someone correct me if I'm wrong) is that it's split into two processes, effectively a client and server.  When you start a new screen session, it spins up both, but only the client is associated with the terminal.  So closing the terminal kills the client (as it should); the server lives on because it never got the HUP.  When you attach a screen, it connects to a running server.

I'm fairly new to linux and I am just curious as to how screen manages to survive the logout process. I don't know the logout process really works either but I assume that screen manages to ignore the signal sent to all the process I own when I logout. I thought that was SIGHUP but when I do kill -HUP <screen pid> it kills the session. Can someone explain how this works?
