Samba and Win viruses
Hi,
This may seem a fairly obvious question but I need to check it out.
It's also fairly urgent so I apologise that I haven't made a good check
of the FAQ's or mailing archives.
We have a Solaris box with Samba installed. We are on a campus network
where boxes that are infected are blocked from the network as a security

User sets or anything similar?
Hello
I got about 20 different people using 20 different PC''s in my Lan. Five
of them should have unrestricted access to the internet any time of the
day. Yet the rest of them should only have access at certain timeframes
during the day. Two of them should have no access at all.
I am well experienced in writing rules (for the rules file) that make
all this possible, yet i was
