I’m not a fan of OSX and I try to avoid it with the same verac­ity that I avoid Win­dows. But I recently needed to have a Linux NFS export mounted on an OSX server. A sim­ple mount server:/export /mymountpoint didn’t work and returned “Oper­a­tion not per­mit­ted”. After a bit of dig­ging I found the solution.

I needed to instruct the client to use a privledged port by adding the “-P” option.

mount -o -P nfssrv:/export /mymount

Now to make it per­sis­tent of course its not as sim­ple as shov­ing it in /etc/fstab and run­ning “mount –a”. No OSX has to be dif­fi­cult. It turned out lookupd got in the way.  To fix it I did the fol­low­ing after con­fig­ur­ing my fstab.

mkdir /etc/lookupd
echo "LookupOrder Cache NI FF" >> /etc/lookupd/mounts
kill -HUP `cat /var/run/lookupd.pid`
mount -a

Yay that should have mounted your NFS mount and have it be persistent.
