I have a laptop runnung Lubuntu 13.04. I use "ssh -X" to log into my server and start programs there that I view on my laptop. When I pull the ethernet cable, the laptop switches to WLAN but my "ssh -X" windows turn black. My IP changes due to the switch, and this disrupts the ssh connection.
My router is unable to give two different MACs the same IP.
So, is it possible to set a fix IP for both wlan0 and eth0?
