How to get new ip address w/dhclient

pbr · 11-09-2004, 08:49 PM

Every once in a while my cable/modem drops the internet connection and assigns me a new IP Address when it connects again.

I can't get back internet service on the linux box unless I force an ip address update.

When I lose the connection does linux notice? Will it try to keep using the old IP Address as long as it thinks the lease is good?

Is there some way to configure dhclient to get a new address automatically without me?

Thanks.

Have you tried "ifdown eth0 && ifup eth0" ? When it brings it back up, it should try to get a valid IP from the DHCP server.

I have a similar problem, on a ClarkConnect box routing my home network. If the cable cuts out for awhile, the box automatically assigns eth0 a 192.168.x.y IP. When the cable comes back up, it resets to a real IP, but iptables is borked. I read somewhere that a "service firewall restart" clears it up, but haven't had the chance to test it, yet.

I can get things working in several ways, just that I need it to update things when I'm not at the computer. I host several websites on my linux machine and they stop working until I do the update.
