Noel,
Since UNH Housing owns and operates the CATV plant on campus, at this time
it is not a problem.
We have about 200 users on campus using cable modems managed via the CATV
head end, which gets it's data feed via fiber from telecom. This complex
was not wired for ResNet when the rest of the campus was, and housing chose
to use the CATV plant since it was already in place.
Good luck,
-mike
Is anyone having issues with rooms connected to Resnet via ethernet and an
outside internet connection like a cable modem or DSL?
Our internet connection is no longer the fastest service around. Evergreen
housing residents who want faster internet connections are signing up for
cable modems, which seems reasonable to me as it makes them happy and gets
traffic off Resnet. However some people in our campus IT department are
very nervous about the possibility of a multihomed machine in Resnet
circumventing the campus firewall. Resnet is a network segment inside our
campus firewall so students can access file shares on student use servers in
our labs, but the segment can't access our administrative db servers. I
don't want to move Resnet outside the firewall as that would cut off access
to machines in the labs.
I've updated our RUP to prohibit multihomed devices, but that doesn't make
our administrative IT folks feel much better. I'm not even sure how to
detect a multihomed machine on our network, the only one we've found so far
was easy to track down as it was also a rogue dhcp server. Any advice is
greatly appreciated.
Thanks,
