tcpdump tip

29.07.2005 14:13

If your tcpdump isn't showing any packets when you know it should be (like, you can ping another machine, but tcpdump doesn't show any packets on the wire), then the problem can be that it can't get a reverse DNS look up for the IPs in the packets it is receiving. You can use the -n option to turn off reverse lookups and solve this problem (or better, fix your DNS configuration).
