[nwst-dev] Working config for kernel 2.4.21

[Geltmar B. <ge...@gm...>]

Hi again,

I am not sure what is going wrong with your setup.
Enclosed you will find the bits, which work for me.

###########
The relevant bits during startup look like this:

Linux version 2.4.21 (root@debian) (gcc version 2.95.4 20011002 (Debian
prerelease)) #2 Tue Aug 5 23:25:22 CEST 2003
...
Kernel command line: console=ttyS0,9600 console=tty0 root=/dev/nfs
nfsroot=/home/NetworkStation ip=dhcp
...
Sending DHCP requests ., OK
IP-Config: Got DHCP answer from 10.0.1.100, my address is 10.0.1.50
IP-Config: Complete:
      device=eth0, addr=10.0.1.50, mask=255.255.255.0, gw=10.0.1.1,
     host=10.0.1.50, domain=buxhoeveden.net, nis-domain=(none),
     bootserver=10.0.1.100, rootserver=10.0.1.100, rootpath=
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
Looking up port of RPC 100003/2 on 10.0.1.100
Looking up port of RPC 100005/1 on 10.0.1.100
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 136k init 36k pmac 8k chrp 4k openfirmware
############

#/etc/exports on the computer that acts as dhcp and nfs server:

/netstation/prodbase	10.0.1.50(rw)	#that is where my kernel.1000 lives
/home/NeworkStation		10.0.1.50(rw,no_root_squash) # that is root i.e. "/"
for the Netstation
/home/geltmar			10.0.1.50(rw)	#my home directory on the server
#############

#/etc/hosts.allow on dhcp/nfs server

ALL: 10.0.1.*
#############

#/etc/dhcp3/dhcpd.conf on dhcp/nfs server

option domain-name "buxhoeveden.net";
option name-name-servers 145.253.2.11;
default-lease-time 600;
max-lease-time 7200;

host netstation {
	hardware ethernet 0:0:a7:24:17:4b;
	fixed-address 10.0.1.50;
	filename "kernel.1000";
	server-name "10.0.1.100";
}

the filename "kernel.1000" is
probably not necessary, if you configure the NVRAM in the netstation itself
???
to boot a kernel from a specified location,
but the kernel is configured to use dhcp for an IP, so I guess it is needed
in the
second phase of booting to get the nfs stuff running.
#############

My kernel is 2.2.21 self compiled, as I had to change the
nfsroot=/home/Networkstation bit
for the kernel command line. Other changes are, that I compiled drivers for
the
parallel port as modules to keep the kernel small, as I don't use a printer.

Have a look in /var/log/syslog et al on your dhcp server and try to find out
how far
mounting nfs works. I used to get "permission denied for..." errors by the
nfs server,
if the IP address of the Networkstation and the lines in /etc/exports did
not match.

Did you have a working 2.4.19 kernel, as another user reported and it
stopped
working once you switched to 2.4.21? Or did the station not boot at all?

Maybe having the kernel "ouside" nfsroot as in my configuration is
necessary, I am not sure?
I had to move nfsroot to a disk partition with more space so I ended up with
this configuration.

Maybe you can find any differences to your configuration.

Good luck

Geltmar
