NFS mounting
 

Hi all,

I apologise if I posted in the wrong thread as I am not sure which category this falls under.

I am trying to get my arm board to obtain it root file system from the host my laptop but I encounter lots of problem and require some help.

what I have done:

- my arm board ip = 192.168.0.38 (interface to host => ethernet cable and serial port)

- host Ethernet address = 192.168.0.123

On host
- added in /etc/hosts.allow

portmap: 192.168.0.38
lockd: 192.168.0.38
mountd: 192.168.0.38
rquotad: 192.168.0.38
statd: 192.168.0.38

- added in /etc/hosts.deny

portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL

- added in /etc/exports

=> /home/EVA/Desktop/Project 192.168.0.38(rw,sync,crossmnt)

- under system services:
turn on netfs, nfs, nfslock, rpcbind
turn off iptables
firewall disabled

chkconfig --list iptables
iptables 0: off 1: off 2: off 3: off 4: off 5: off 6: off

chkconfig --list ipchains
error reading information on service ipchains: No such file or directory

For client

- under linux kernel Kconfig
=> enabled NFS client support with NFS version 3 client protocol
=> enable “Root File System on NFS”

Kernel Commandline =
console=ttyS0,115200 root=/dev/nfs rw nfsroot=192.168.0.123:/home/EVA/,nolock ip=192.168.0.38:192.168.0.123::::: off

Problem:

When I run my kernel on the arm board it gives me the following

...
Kernel command line: console=ttyS0,115200 root=/dev/nfs/ rw nfsroot=192.168.0.123:/home/EVA,nolock ip=192.168.0.38:192.168.0.123::::: off
...

Can someone tell me what's wrong with my setup?
Thx

That looks to me like the initial problem is the network card isn't starting up properly. Are you using the correct drivers?
