I am trying to mount a remote filesystem hosted by a Linux machine.
The filesystem is properly exported and can be mounted by other computers.

I have tried entering the information into netinfo as instructed by:

http://deaddog.duch.udel.edu/~frey/darwin/archive/DarwinAndNFS.pdf

I have tried using mount -t nfs and tried mount_nfs.

Example:
mkdir /test1
sudo mount_nfs remotehost:/local /test1
cd /test1
bash:cd: /test1: Operation not permitted

In all cases, the mount succeeds, but when trying to access the directory, I get Operation not permitted. I have used su to login as root with the same results.

Any help would be greatly appreciated.

NFS in insecure mode... only over teh vpnage.
