debian ip and gateway settings change
Recently i changed my router's ip and i changed my workstation's ip. I did
ifconfig eth0 down
ifconfig eth0 new_ip netmask 255.255.255.0 up
route del default gw old_gw_ip
route add default gw new_gw_ip
But after restart computer sets back old settings. How to i change computer network settings permantly. I'm using debian sid.
