NFS File Permission Issue

Hello,

Have any one explain NFS File permission.

I have configured NFS server and i have assigned 755 permission for NFS shared folder(Folder created by root).

/etc/exports look like,

/nfsshare 192.168.5.1(rw)

/nfsshare 192.168.5.2(ro)

but I am not able to get write permission in NFS shared folder.

If I change NFS folder permission to 777, both 192.168.5.1, 192.168.5.2 have write access.

can any one help on this issue.
