prived ports for NFS on FC3

Is there a way to force mount to use a privileged port when mounting
from an NFS server with Fedora Core 3 as the client?

I realize it's not that useful for security purposes, but the server I
need to access requires it and that is outside of my control.

TIA for any help,
Anthony

Try:

man mount
/mountport

And see if this option helps.

That's the remote port to use. I did try it, but it doesn't work because
it's trying to connect to a port the server isn't listening on.

Thanks for the response.

Ah see, you mean something like the "insecure" option linux nfsd
provides to allow clients using privileged ports, only in the
other direction? Dunno about something like that, probably because
it was never needed, Linux nfs works nice with a couple of other
*nix nfs. Perhaps you can get more hints if you name the system?

Or if there's a ng for this system, try that, perhaps someone can
give a hint?

Sorry about this, but the problem was unrelated to the port in use and
is now fixed.

It turned out that my problem was because I had raised the MTU on the
server but not the FC3 client, as it was a fresh install. The server's a
bit slow for a gigabit network (P2 400), so it nearly doubles throughput
when I raise the MTU.

It caused identical symptoms to some previous problems I've had with
non-privileged ports (that was on MacOS), but it was trivial to fix once
I realized what I had done. I think I just posted this because one tends
to find mistakes faster as soon as other people are involved.

Thanks for the help though, even if all I needed was an opportunity to
look foolish.

No problem, at least you have the balls to come back and clear
things up, thx!

Good luck
