FYI,
Looks like a binary 1010.... Perhaps an ethernet preable run away from a
defective NIC or hub port some place.

I have seen the LAND 85.85.85.85 attacks on our network a
few months back. We were having a problem with one of our routers at the
same time. When I swapped out the router, NFR no longer picked up those
messages.

Anyone have any idea what I might be seeing here? I just
turned up an NFR
probe at Exodus in DC, and I'm seeing all sorts of traffic
as follows
NFR: dc-probefe
Source: 85.85.85.85
Destination: 85.85.85.85
Type of attack: Land
Protocol: 1
Src Port: 0
DST Port: 0
ICMP Type: 85
ICMP Code: 85
Packet:
E\\x00\\x008\\x80\\x1e\\x00\\x00\\x01\\x01UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Count: 1
I also get occasional variations as follows
NFR: dc-probefe
Source: 85.85.85.85
Destination: 85.85.85.85
Type of attack: Land
Protocol: 6
Src Port: 21845

ICMP Type: 0
ICMP Code: 0

and
NFR: dc-probefe
Source: 85.85.85.85
Destination: 85.85.85.85
Type of attack: Land
Protocol: 17

My probe is sitting in front of my firewall box, and when I
do a tcpdump on
my firewall searching for any of these packets, nothing
comes up. The only
thing I can figure is that this is some sort of weird packet
thats being
misinterpreted by NFR. Perhaps some sort of ethernet
broadcast being used
by Exodus's Foundry VLAN's?
Just curious if anyone else has seen anything like this on
an NFR system or
otherwise.
