NFS - group permision problems on client side


fiollowing configuration:
Server: kernel 2.4.22, /etc/exports "/export/pic,no_root_squash)"
Client: kernel 2.4.22; mount -o rw server:/export/pic /mnt/pic

/export/pic/animate is owned by "mickey" group "disney" permission "770"

/etc/group and /etc/passwd are the same on both machines.

on Client machine:
When user "goofy" member of "disney" tries to access /mnt/pic/animate he gets a permision denied.
On the contrary on Server
user "goofy" can access /export/pic/animate

The behaviour for user goofy depends on the actual location. How can that be? User goofy is the same on Server and on Client.
How can I overcome this permission problem

NFS permissions

Carefully check Your settings within /etc/exports:


The netmask is at least somewhat unusual. Did You really intend a 20bit mask instead of the (implicit) 24bit mask?
If You did not intend the 20bit mask, change the line to
or better to

Reexport (exportfs -av) and test again.

On the client, you can easily check a servers exports using
/sbin/showmount -e servername
If showmount fails, either the servers nfs service or the servers exports or the clients nfs utilities have not been set up correctly
