Hi folks,
I need help in figuring out why i am having som real
bad nfs troubles. I would appreciate some advice. I
have included the information that i thought was
relevant. The authentication on the client happens
from the server using NIS. The authentication happens
flawlessly.
thank you
regards
confused.
setup:
cluster of machines on a private network each
connected on a gigabit network.
The home directory on the server is mounted on the
client side by the command mount r2d8:/export/home
/home . Happens instantaneously. ls -l works just
fine.
