Nice try. But if the rootkit is any good you hve been using the rootkit to
find it's presence. And that is something the root kit will hide from you.
The fact that you only have ARP request does not mean a thing. And the
other attachment is DHCP traffic. Which is propably the way you have
configured your internet connection.
So this sounds like a hunting ghosts. And snort is NOT the best way to
trace traffic.
If you suspect your machine is compromised you can not rely on anything at
all from that machine! Boot from clean media (CD or write protected
floppy) and investigate from there.
