Correct me if I'm wrong: you want an equivalent of the below to actually work (speaking strictly from an /etc/exports perspective): /FreeBSD -ro -alldirs -network=192.168.1.0/24 /FreeBSD -rw -alldirs -network=192.168.100.0/24 /FreeBSD -ro -alldirs -network=10.0.0.0/8 Is this right? If so, I can imagine addressing/fixing this will be complex. > I'm starting to think we should either mimic such functionality from > OpenSolaris or invent it. I agree. A centralised command like share(1) would be sufficient for what's needed; in concept, something like pw(8) for NFS shares. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
