[Soekris] net 4511 PXE boot won't mount NFS

[Larry Boehm]

Ted,
Thanks for the advice...
This is my current pxelinux.cfg/default

SERIAL 0 19200
DEFAULT vmlinuz console=ttyS0,19200n81 root=/dev/nfs
nfsaddrs=192.168.0.105:192.168.0.26:255.255.255.0:soekris:eth0
nfsroot=192.168.0.26:/nfsroot/debian panic=10
IPAPPEND 1

Actually...notice how I conveniently left of the route/gateway
address...hmmm.

It should be this:
SERIAL 0 19200
DEFAULT vmlinuz console=ttyS0,19200n81 root=/dev/nfs
nfsaddrs=192.168.0.105:192.168.0.26:192.168.0.1:255.255.255.0:soekris:eth0
nfsroot=192.168.0.26:/nfsroot/debian panic=10
IPAPPEND 1

Yep...that did it.  Don't you hate silly mistakes!

Thanks!
-Larry

This is the bit that I think is interesting:

At this point eth0 is up.

And at this point eth0 is down again -- I see the "remaining active"
message when I use ifconfig to take an interface down.  I'm guessing that
the preceding line (IP-Config: Incomplete network configuration
information) is suggesting what has gone wrong.

And error 101 is Network unreachable, which implies that you don't have a
route to 192.168.0.26, confirming that eth0 is down


I'm guessing that you need to add an "ip=dhcp" line to your kernel args in
the pxeboot config file.  My /tftpboot/pxelinux.cfg/default file looks like
this:


---8<---

DEFAULT nfs

SERIAL 0 57600 0

LABEL nfs
kernel vmlinuz-2.6.16.16
APPEND root=/dev/nfs ip=dhcp nfsroot=/scratch/cerberus/root,ro
init=/sbin/init c onsole=ttyS0,57600

--->8---


Cheers,
