Hi,
Sorry but I write you not to give you a solution but another question
!!!
We would like to use nfs connection through a firewall.
The version of our OS (HP-UX) can not use fix IP adresse for this case.
So when I read your message I thing that perhaps if I use an ssh tunnel
for the nfs protocol it could be solve my firewall problem.
Is it right ?
