What !!!!!
Kevork, how come you are allowed to get internet access at public prices when the rest of us have to pay for one of the exorbitant
"approved" provider deals ????

Hi Neil,

 We have an Optus cable account ( not sure if they are still available to schools ...we were a trial school back in 1995 ) at 20 GB
peak ( 12 noon to 12 midnight ) and 24 GB off peak ( 12 midnight to 12 noon) at $330 per month  < $4K per year. That works out at
0.75 c per MB. 

 Students get 100 MB per month each and occasionally are topped up. There is no cost recovery imposed on the students with internet
access. 

 We give $20 print credit per semester which does require an actual payment to top up if breached.

Regards
Kevork

Our costs have gone nuts this month too - again, anonymous proxies.

Russell - who is your provider, and what do they charge you per meg?  We are with SINA and the schools cops 9c per meg traffic
charge. I budget about $15000 traffic charge per year, and often exceed this (1500 per month, exc January, most of holidays and a
lot of December).

We use ShapeShifter on a Novell BorderManager to throttle our port 80 bandwidth but still get excessive charges through peer to peer
and streams that are not properly disconnected.  Our ISP does the accounting and I am not convinced that their accounting is
accurate.

Can anyone else share their costs management strategy, and perhaps the way they charge students?

James

we use a combination of tools:

Papercut to control web access - works very well and we give all students 25 meg per week.
Squid to block access to a list of sites SARG to randomly check who is using the latest proxy unblocker sites

If students do manage to bypass Squid via  proxy unblocker, then they can only access up to their credit limit anyway.

cheers
Russell

Hi all,

sorry for the cross posts. 
Firstly, thanks to all the people who replied to my query last week about Value Adding through VB programming, it was most helpful. 
I have another problem and would appreciate any advice. lately, we have had a spate of students using proxy servers to bypass the
school's internet restrictions. Word is spreading that this can be done amongst the students and it has proved impossible to block
all sites that provide proxy access. 

At the moment we cancel internet access to those students we catch but we only catch them by fluke and we don't want to end up
banning large number of students from the internet but if we let the students know these sites exist it will advertise the fact and
more will use them.

Has your school had these problems and does anyone have some advice on what to do?

Thanking you in advance
