NFS server on Mac OS X
If you ditch into Mac OS X you easily find that under Aqua there is BSD system underneath.
It comes with all the goods a proper Unix system should have.
Running NFS (Network File System) on Mac OS X is very easy.
If you read /System/Library/StartupItems/NFS/NFS script it clearly says what should be run,
in which order. First of all you need portmapper(8), nfsd(8), mountd(8), rpc.lockd(8) and
rpc.statd(8) deamons running. Quite a lot, ain’t it? You can run them one by one or via NFS script but it’s much easier to create /etc/exports file and reboot the system.
At the startup, when /etc/exports is found, the NFS server is run.
To create a share, edit /etc/exports file. It does not exist by default so create it first:
# vi /etc/exports
and add:
/Users/gregory/tftp -ro -mapall=nobody
I export /Users/gregory/tftp directory, read only filesystem, map EUID to nobody.
Save the file and reboot.
To check if RPC is working properly issue
root# rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 1019 status

100003 3 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
To check what is exported by localhost, issue:
root# showmount -e localhost
Exports list on localhost:
/Users/gregory/tftp Everyone
To mount a share from a client issue:
root# mount -t nfs 192.168.0.101:/Users/gregory/tftp /Volumes/nfs
