Re: arpwatch and more

Well, you could buy a managed switch from HP or Cisco. :-)

Personally, I have no idea how to do this sort of thing with Linux; but it's probably better to do it at the backbone with a reliable switch than to throw in extra servers with multiple network cards all over the place (which would increase the point of failure several times...incoming cable, NIC, server, NIC, outgoing cable, etc).

can someone tell me how to secure a network so that:

it would keep people in line.
better, a table with mac addresses and ip(s) (its already there), but have
it authenticated so you can't just bring up an ip without pre-assignment.
And, do many of you do something like this on multiple colocated servers
from independent clients with your switches?
limit the mac addresses on the port to the router and the colocated box,
e.g. the other people can't see that box.
