You probably mean to run "screen" in "ssh", i.e. screen on remote end? Otherwise with "screen to run your ssh in", instead of using GNOME terminal's pty, you're using screen's pty, with nothing changed at the network interface level.

Actually, come to think of it even having the same IP address on both networks may not work. Off the top of my head, it would depend on: 1. Whether your NAT provider sees LAN and WLAN packets coming over different interfaces or the same interface, and 2. Whether your NAT provider is interface-agnostic or not. If your packets are coming over different interfaces, and the NAT box is storing the interface as part of the connection meta-data, then even having the same IP on different networks may not work.

If you want to continue using the same connection over LAN and WLAN, you will have to either have the same IP address on both media, or use an app like screen to run your ssh in.

[ilugd] SSH KeepAlive with Switched Networks
Is there a way to overcome this situation. Situation : I’m on a LAN [in office] connected to remote server over SSH [using gnome terminal], now I've to go over for a meeting on another floor along with my notebook. I switch on to mine office WLAN with a descent 90+ signal strength, Network manager shows both connections there as connected. I disconnect my LAN connection and now on WLAN when i try working on the server to which i was connected, the server is not responding to my keystrokes as if the connection broke and i have to make a new connection to the server in order to use it in a new tab. The old connection [the one over LAN ] breaks after some time, with a timeout message. Configuration tried out : I have the settings done for keeping SSH session alive by adding entry 'ServerAliveInterval 30' to '/etc/ssh/ssh_config', but that fails to work in my case. It only supports in case e.g. i connect to a server over LAN [ have both LAN and WLAN active ]. I break the LAN connection, now over WLAN the server does NOT shows any response to my keystrokes [let it be ENTER key]. I connect back to the LAN, and it works, also all of my previous key strokes are responded to. Any help will be great.
