-----Original Message----- Subject: [Snort-users] need help : (snort decoder) Bad Traffic Loopback IP
On one machine i get a (snort decoder) Bad Traffic Loopback IP with 127.0.0.1:2638 255.255.255.255:2638 UDP report. How can i trace where this broadcast came from (pid)/PC ? I wonder why only one pc gets this broadcast msg, for testing i pulled
this pc out of
network and msg didn't come again. Now i wonder if it is generated by the pc itself - but why vanished msg
when pulling off
network cable- or if msg comes from network - but why don't fetch other
sensors this msg - .
i don't wanna disable complete decoder to get rid of this message. But in
the end i'd like
to find out what src of msg is and stop it.
Step 1 will be to determine whether or not the packet is actually "on the wire." This can be done with Ethereal or whatever your favorite sniffer is. Just be sure to specify the actual interface you think the packet may be arriving on when sniffing. I suspect that you will discover that this packet is not occurring on the wire but only on the local network stack. The easy fix for this will be to specify Snort's listening interface using '-i'. That way, traffic that occurs on the local machine's loopback interface won't be processed by Snort.
