Strange pings from 127.0.0.1

["Marc" <gg () stober mailsnare net>]

The networked applications I am responsbile for have been performing slowly.
When I tried to run Ethereal on my computer, I found some odd ICMP echo
request (ping) packets with a source IP of 127.0.01, to addresses both
within our 192.168.1.* network as well as to random Internet addresses. The
source and destination Mac addresses aren't anything I can associate with a
computer on our network (and they're not the real Mac address of my
computer), so I think maybe these packets are spoofed? Could this be some
sort of virus or DOS attack somewhere within our network? I've haven't seen
anything quite like this mentioned online anywhere.

Thanks, Marc
