I've managed to make nfsroot run via my eth1. My eth0 connects to the
DSL modem using pppoe. As soon as I do that, causing the ppp0-interface
to be added, the root filesystem is no longer accessible. It even seems
the entire eth1 subnet is down because I can't even ping the host anymore.

What can I do to make nfsroot run in harmony with pppoe?

TIA,

You probably have set a default gateway on eth1, and started ppp with
the "defaultroute" option. You should only have one default route,
that is your connection to the outside world. eth1 should have a route
to the nfs server or the subnet in which it is located.

Bill,

thanks for your reply. Here is my routing table:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
bsn10.fra.qsc.d * 255.255.255.255 UH 0 0 0 ppp0
192.168.101.0 * 255.255.255.0 U 0 0 0 eth1
192.168.102.0 * 255.255.255.0 U 0 0 0 eth2
default bsn10.fra.qsc.d 0.0.0.0 UG 0 0 0 ppp0

This is after a successful ppp0 dial-in using the same kernel from
/dev/hda1 that I would like to use via nfsroot. The NFS server is
192.168.101.1, so I have an explicit route to that network for the eth1
interface. This doesn't seem to help.

Any other ideas?
