Subject: NACHI !!!
Hi guys,
Nachi virus stroke my network. My router melted down after the attack.
As such, there are huge no of PC's sitting on the inside interface of
the firewall. the router having the internet link is sitting on the
outside interface of the firewall.
The internal users/servers are connected to the PIX via a 4507 internal
L3 switch.
I have identified the traffic coming from inside to outside on port 0800
(icmp type 8 packet) from the patted IP to some arbitarty IPs on
internet. I have blocked icmp on PIX and stabilised the situation.
But I still am not sure, which hosts on the internal network is pushing
this traffic (ie affected with nachi). Am ready to put nachi patches in
all the 500 odd machines,
but is a bit tough !!!
Is there any way to find the machine pumping this traffic from the
switch ? am not able to enable ip route-cache flow or ip accounting on
the vlan interface nor able to enable MLS. Is there any other way to see
this information?
Cheers
Raj
