Can just be iptraf doing DNS lookups of stuff flying by. Incidentally this is a good way to realize if someone who doesn't realize they should turn off DNS lookups is running tcpdump or another sniffer against you locally... but in this case it is you running the sniffer and creating the noise, so no worries :-) -Andy
Hi Andy, You were spot on. I disabled the reverse DNS lookups in iptraf and all went quiet. Thanks for your reply. Regards Vijay
