Thanks in advance. Edit /etc/init.d/network and reboot is the EASIEST way for a newbie. No need to reboot, just shutdown the NIC: ifconfig eth0 down and then run the /etc/init.d/network (after you edited it of course): /etc/init.d/network Oki

But the routes are there. At least the routes for the local network are there. (2.2 kernels add them automatically, don't they?) I even tried to manually bring down all ethX, remove all routes and start them up again. Still doesn't work until I reboot in frustration. Can't even ping other hosts in the same network. Perhaps I overlooked something To Lindsay: I tried manually using ifconfig already :(

Jonathan Chang said: Is there any standard way for debian to change ip address? Or I need to modify files in /etc manully? Thanks in advance. To change it temporarily (until the next reboot), use ifconfig. For a permanent change, yes, you have to edit a config file in /etc. (/etc/init.d/network, to be exact.) -- Geek Code 3.1: GCS d- s+: a- C++ UL++$ P L++ E- W--(++) N+ o+ !K w---$ O M- !V PS+ PE Y+ PGP t 5++ X+ R++ tv- b++ DI D G e* h+ r++ y+
