Fwd: mac-ip pairs

[Petre Bandac <g38@rdsbv.ro>]

hello

I have a small problem:

a network (something about half of a C class IPs) and some users who I'd like
to "stick" them to only one IP; half of the computers get their IPs via dhcp,
the others are fixed.

I was thinking of mixing arp -f /etc/ethers with some iptables rules, but the
question which arises is if I "stick" the mac on the ip, or the ip on the
mac, i.e. if the mac X is tied to the IP Y, will the mac X be able to have
the IP Z (since the IP Y won't allow itself to another ethernet)

hope I'm not too ambiguous,

thanks,

petre
