We use Trend Micro's Webmanager here. It works very well, acting as a transparent proxy server forwarding its traffic to an upstream proxy server. It pulls the user name out of the challenge responce from that upstream server and assigns the use a quota that has been predetermined by us. It also puts a small java windows on the user's screen showing how much of that quota has been used and how much remains. It can also do website filtering and scan http traffic for viruses.
Unfortunately it's not free, but a very good product IMHO. Availible for a number of different operating systems including Linux :o) > > > > >On Thu, 16 Oct 2003 12:40, you wrote: >> I've got a problem.
