ssh security question

[Martin F Krafft <madduck@madduck.net>]

my laptop has two net interfaces, one wired and one wireless. they
have different MAC addresses, but i configured my DHCP server to treat
them the same so that i usually have the same IP no matter what card i
use.

i just noticed a curious bit of possible security awkwardness. with my
wired card, i established an ssh2 connection to another machine on my
subnet, then i proceeded to swap the cards - and i could continue
using my ssh2 session as soon as the new card received an IP (the same
one). now i ask you - this smells like a problem to me, or not?
shouldn't sshd at least worry about the MAC address too (can it?) just
an IP is too easy to spoof (MAC are too i guess).
