Heheh - I went through an exercise like this a few
days ago - 'cept it was to stop certain users from visiting the softporn sites
at clubs.yahoo.com. Apart from the company having a rather stern
view concerning employees visiting "adult"sites while on the job, the damned
idiots were filling up my log files. I simply blocked all Yahoo URLs 'cept
for www.yahoo.com, mail.yahoo.com, and one or
two others that slip my mind at the moment.

I don't think it can be as easy as blocking TCP
ports, because it can use HTTP.
I see it connecting to port 80 on
es2.yahoo.com [204.71.200.59], es7.yahoo.com
[204.71.201.128],
p7.msg.yahoo.com [204.71.202.138], and there are surely
more
servers.
It may be easier to look at the logs with a specially
written program that, say,
looks for yahoo.com and somehow filters
www.yahoo.com and mail.yahoo.com and all
of its variants, and then finger
the timewasters.

We're having a problem with our employees wasting time on Yahoo
Instant
Messenger. I'd love to nip this problem in the bud before it
gets really out of
hand. Can anyone give me some tips on how to block
this thing out? Stuff like
IP ports?
Any help will be
appreciated.
Thanks,
Cooper
