Knoppix v3.7 hd installed to PC A (Terminal Server, IP:192.168.0.200)
PC B (Diskless client) Could boot to KDE.

PC A exported "/export" directory with read/write right
PC B mounted PC A 's "/export" to "/mnt/export" by useing NFS.
mount -t nfs -o rw 192.168.0.200:/export /mnt/export

PC B only can read /mnt/export ,
And when I write something to the /mnt/export,
it always said permition denied.

Thanks for your patient
Anyone knows why?
