Thanks Erek for your nice explaination. So just to confirm ,if I add the below lines "var HOME_NET $eth0_ADDRESS" in snort.conf, along with other configuration lines and "/usr/local/bin/snort -i eth0 -l /var/log/snort/ -d -b -c /etc/snort/snort.cond -D -p " will meet my requirements that "running snort to watch the network traffic destined only to my machine and also taking care of the changing IP address in DHCP scenario" If I am wrong somewhere , please correct me.
Exactly. You can also modify your command line to be a bit 'better'. If you are logging to binary (unified, pcap, or -b) then -d is a waste of time. No need since the packets are dumped as a whole. You can also drop the -p since it doesn't matter. Only use the -p if you need to. Since you are a single node on a DHCP net, then promisc mode does not matter. You'll still see broadcasts and ARP requests... Cheers! ----- Erek Adams "When things get weird, the weird turn pro." H.S.
