On our high speed dialup modem pool that runs SLIP our users are known
as "campers". Some never hang up. This probably has alot to do because
we don't charge for the service. Clearly a suboptimal scenerio. There
is a big contrast between what we see on the "terminal" modem pools
which are under-utilized.
In comparision, and going back to the basis of this disscussion, we
also have 10Base-T available in all on-campus dorms at no charge. Last
year we had 4mb/s Token Ring in all dorms which was removed over the
summer at which time we also added 10Base-T to the remainder of the
dorms that did not have ethernet service. We also have AppleTalk
service available in all dorms as well as direct SLIP lines in some
dorms. There are 33 dorms in all including Fraternities and Sororities,
some bigger some smaller. All is at no cost to the students. They have
to buy whatever cable/adapters are needed to go between their machine
and the IBM wall outlet (one outlet per bed). Likewise with dialup
service they have to buy the modem and pay for the call.
We make it known that there are approved network adapters and software
(BootP and Mac TCP) and have the students take on the responsibility of
purchasing, setting up and connecting everything on their side of the
outlet. Those with non-approved configurations are pretty much on their
own.
Unlike most institutions that have Residence Life/Housing coordinate
the network connections, we have our Computing Services department
handle everything in which my group (Data Communications) is the
department within the division that is directly responsible. We also
have a seperate Computer Store that sells all the user's equipment.
With more advanced students every year (complete with advanced network
sniffing devices) this becomes more and more of a challenge.
