NFS server returns error for client mount calls. error 13

I’m working with OpenSusse 11.2. I installed and activated the NFS server via yast2.
I exported the relevant directory via yast2 (NFS server configurastion)
I’m trying to setup my Linux target to boot via NFS. The kernel boots up but fails to mount the file system. When looking on a capture from ethereal it can be found that the NFS server return error when client try to mount the /nfstest directory from this server. The returned error is 13


The boot command:
setenv bootargs root=/dev/nfs rw nfsroot=
ip= console=ttyS0,115200

The output for **exportfs -v **as follows:
/home/gidi/nfstest <world>(rw,wdelay,no_root_squash,no_subtree_check)
/home/gidi <world>(rw,wdelay,crossmnt,no_root_squash,no_subtree_check,fsid=0)

The directory permission was set to nobody:nogroup by:
chown nobody:nogroup /nfstest

I’ll appriciate your help on this issue.

error 13 means permission denied.
your bootargs should be like this:
setenv bootargs root=/dev/nfs rw nfsroot=
