A common problem in connecting NFS on OS X machines is that, they do not connect on “reserved ports” (i.e. $<$1024). Two ways to solve: On the NFS server, use “insecure” keyword in the
/etc/exports to accept so-called insecure ports for connection. Or in OS X side, instruct to use reserved ports. Command line:
mount_nfs -o resvport server:/exported/path /local/mount/point
For Cmd-K in Finder, we need a trick. First go to Disk Utility, in the “File” menu, pick “NFS Mounts” to add a remote NFS location to the list. Then, in the “Advanced Mount Parameters”, type in the option “resvport”. Thereafter, typing the same NFS location
nfs://server//exported/path on Cmd-K will use this parameter.
