If I run ipconfig -a command, then I see iface eth0 too but > its ip address is still the old one: 10.31.253.153 The reason is that "/etc/init.d/networking restart" boils down to "ifdown -a --exclude=lo; ifup -a --exclude=lo" and "ifup -a" only brings up interfaces that are marked "auto" in /etc/network/interfaces. Running "ifup eth0" will bring the interface up again and change your IP address. Sven -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
