NFS time based access restrictions

[Darryl Moore]

Oh that's easy. My home server hosts videos. Everything I've ripped
and/or downloaded in the last decade is there. I want to make sure the
kids can't access it between the time they get home and after supper.

Perhaps another solution is to change the group ownership of the
directory and use cron add/remove the kids from a videoviewing group.
I'm using LDAP for authentication already so that wouldn't be too hard.

Yes, I didn't really think exporting and unexporting the directory was
the best option. I have enough occasional issues with my own laptop and
NFS when it sleep and the wakes somewhere not on the network. If
Nautilus had an NFS mounted directory open when it went to sleep it
causes all sorts of head aches when it resumes.

cheers,
darryl
