Mount a NFS share from Linux to Mac OS X – Snow Leopard

If you get the error ”Operation is not permitted..” when trying to mount a Linux exported NFS mount in Mac OS X, you should check if
the secure-flag is enabled. If it’s enabled, NFS will use privileged ports (1-1024). To mount an export that uses the secure-flag, you can do the following on your OS X machine:

# sudo mkdir -p /mnt/my_nfs_share
# sudo mount -o resvport nfs_server_host:/path /mnt/my_nfs_share
