How would they be able to monitor the amount uploaded and the amount downloaded pending there is a

2gb download and 500mb upload limit ?

it's for the dorms, and they didn't mention anything about registering macs...
Would they do it automatically when you log in ?

Also, if you have several different modems, then you can basically defeat this MAC address rule.. no ?

As soon as you obtain an IP, your mac is registered.

looking at router and switch logs to see what physical ports are doing the most traffic is the most likely.

Really, there are many different ways.

You mean several NICs, since it's a network.

Also, MAC spoofing is easy nowadays.

Not if they require phone call to release/renew IPs when hardware is changed.

Well I use a USB network adapter and a PCI network adapter.
Both have different MAC's...
so wouldn't each have a 2gb down 500mb upload limit ?

That would be the stupidest system ever. That being said, they'll probably do it.

What kind of hardware are you dealing with? And where?

I know of no major university that has a wired residence, but uses dialup technology. Everyone I know of has been on LAN systems for AGES, even when that meant ring and bus topologies as opposed to the current star topology used by 99% of LANs today.

Edit: Ah, I see you got the answer in while I was writing the above.

Now, to answer your question, no. As my previous post said, they'll be using traffic monitoring at the switches to ensure that the physical ports to your room in res don't go over their set traffic limit. Doesn't matter if you use different cards. You can download more from other locations (ie, a friend's room) because you're effectively using their bandwidth. While your campus' network people MAY have instituted MAC monitoring as well (ie, one known MAC allowed per port) I personally think that that would be excessive and only used if people had abused bandwidth heavily in the past. (ie, major use of P2P networks.)

I have no clue what type of system it is, but it just plugs into a Cat5 port no the wall.
They are going from Static to DHCP this coming semester. I guess it's because a lot of people were haviing trouble putting in the numbers to get it up and running.

This may prove good however, if the upload/download isn't enforced.

Many places already do.

bingo, they can simply limit the port in your room

whats going to happen is you are going to have to register your mac address with them, at my school the first time you plug in a comptuer with a new MAC address you are forced to register it on a website.

Regardless if you have two NIC's they are both associated with your studentid/logon, well whatever they use.

Hehe... all the more reason to keep them off the Net...

:D

Depends on how much work the Network Dept wants to do in administering it... they can be real pricks, or slackers...

The way its done here is that a MAC address gets the same IP address.. then the IP addresses are monitored... so if you have 2 NICs then you possibly could get twice the quota... but then seeing 2 ips maxing out their quota would queue a close inspection of the physical port on the switch... and thats one thing that doesn't change... so by the second or third month, somebody would probably be getting a phone call...

Now does that 2gb/500mb limit apply to intranet transfers? 'cause they shouldn't limit your ability to share files amongst dormmates.

at my school, your mac will be blocked. so yes, technically you could get around it... but our network requires you to register, and you only get two ip addresses.

And if you're a repeat offender or something else that is serious (RIAA/MPAA request), then the jack goes off.

And.. we have packshaper sitting on the outbound routers.. sooooo, no p2p for you!
