server nfs and mini2440

Hi, I am new on this forum :) So my mini2440 cannot start because of the
NFS server this what I got from a terminal on linux.

This is my file (network config) on debian : 

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
        address 192.168.1.27
        netmask 255.255.255.0
  gateway 192.168.1.1
        broadcast 192.168.1.255

I have been thinking since 3 days... so please if you have any ideas let me
know.

From my laptop I can ping 192.168.1.50 and I have an answer but the trouble
is still the same...

Do you run a NFS server on your 192.168.1.27 host?

Hi thanks for you answer!!! What dod you mean run a NFS server on my host??

yes it can run

To send rootfs to the target board is that necessary to run internet
connection on both host And client  or else one internet connection is
sufficient please reply soon

Mini2440                          Host
 NFS client  <---- network -----> NFS server

Pravalika. NFS is much more convenient if you use a network switch so that
your host can use the Internet and communicate with your Mini2440 at the
same time. If you do this, you can not use the supplied Ethernet cable. It
is a crossover meant for Mini2440 <---> Host.

Disable SELinux in your Debian and make a hole in your firewall for the
Mini2440 address (or turn off firewall if you are using the direct
connection with the crossover).
