Define "access internet".....
Do you mean *all* protocols? So, you want to stop a 5th system from browsing,
ftp,
ssh, ntp, pop, imap, etc? So, if A, B, C, and D are using these
protocols...which
can happen without direct user input (pop/imap polls, facebook and rss feed
updates,
etc.) you want to block E for an indeterminate amount of time?
Seriously?
I think you need to state the problem you are trying to solve....not ask for a
solution which really sounds wrong headed.
You do realize that the users being barred access will be getting "timeout"
notices
and such on their browsers and they a very likely to be quite irritated in
short order.
Funnily enough, I once worked in a company that did something "like"
this, it was a sort of "network provisioning / monitoring / bandwidth &
time allotment" thingie. It was strictly for the guys in the Mailroom
and the Storage Room.....apparently they were surfing porn and AOL-ing
all day, so the network admins had set it up where the connection would
only run be "live" for a certain amount of time between the two of them,
there were a total of 4 machines two guys in the mail room and 2 in the
storage room. When BOTH machines in the mail room were active, the ones
in the storage room were "dead" until at least ONE of the machines in
the mail room went dead,...don't ask me how they did it......but it
worked......at least until the company went under!....LoL!
