well..... suppose I've 5 clients in my office ( say A,B, C, D, E ) and a

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?
exactly
Seriously?
yes, its my client's requirement ...... I can understand its not the way to go
.... but he pays me for this ... I'm a service provider .. I have to do what
they said and want to do
I think you need to state the problem you are trying to solve....not ask for a
solution which really sounds wrong headed.
If A, B, C, and D are browsing CNN, MSNBC, ABC, and FoxNews is the limit on
E that he cannot browse CBS or that he cannot make an ftp file transfer or
his machine cannot attempt an NTP clock synchronization until one of the
others quits using the network?
if A,B,C and D are using Internet then E must not have Internet access , like
web-browsing, send/receive email, ftp Etc....
if it can be achieved by proxy (squid like) .. I can suggest them
In theory it can. In practice it cannot unless users are forcibly timed
out after X seconds of connect time and then locked off for a period to
prevent them from logging right back in. Without knowledge of precisely
what is wanted you cannot answer the homework question, Charlie.
