NFS exports and netgroups

[Matt Weatherford]

Hi,

I cant seem to find a good example of an NFS exports file for freebsd that
uses a netgroup to restrict mount access to a group of machines.  Can
anyone shoot me a netgroup example file I could look at?

Ideally, the example would allow rw access to both a netgroup and an IP 
range


like:

/export/project1    cluster1  192.168.220.0/24

so machines in cluster1 netgroup and any machine on the 192.168.220.* 
network
would be allowed to NFS mount.

Thanks in advance,

Matt
