Switch DHCP to Static IP

I have a stable gentoo 1.1a, running KDE3.01, with a tulip-compatible NIC, which has worked perfectly under dhcp with a switch/router acting as the dhcp server. I need to change to static IP for my small network (4 machines). Here's what I've done so far:

1) have modified my hosts file to reflect the new static IPs
2) followed the Gentoo Install instructs for static config. This includes running /sbin/ifconfig and /sbin/route add (apparently successful) for the nic and the gw (in the latter case)
3) confirmed /etc/resolv.conf was still appropriate
4) tried to remove dhcp using rc-update, but no such module as dhcp,dhcpd, or dhcpcd exists.
5) After doing all that, in KDE, the Control Center|Information|Network Interfaces shows the NIC with both the correct static IP and lo address assigned. But there's no Modify or Add or Edit button. I can ping the other machines on the LAN and also can ping the router/switch. But there's no web access with either Konq or Mozilla.
6)One final interesting thing: rc-update add eth0 default yielded "/etc/init.d/eth0 not found, aborting". Can someone clue me in?

I also did a google search, and searched these forums, and got 2840 hits. Way too many to wade through.

As it stands, it looks like I need to disable the dhcp/dhcpd/dhcpcd module (Whatever it is) at boot time. AND initialize the nic and add static config of the NIC at boot.

Does KDE have a configurator for the network interface? I can't find it anywhere, if it exists. It would be incredibly helpful. Since I can't connect anymore, emerging another app from gentoo.org is not possible.

I think I'm way off the track here somewhere.

Thanks,
Rob W.

I can't speak for KDE, but the file you want to concentrate on is /etc/conf.d/net. Set up the "iface_eth0=" line, and the "gateway=" line at the bottom, and then:

Many thanks to rac; I'm back on the LAN and the web on my gentoo box. With your instructs it was a three-minute fix. Bingo!

We live for these moments of small victories, don't we?

This failed for me, because /etc/init.d/net.eth0 start always reset my manual configuration of ifconfig and route.
Then I edited /etc/conf.d/net which is used by /etc/init.d/net.eth0. And now it works!
