I've checked that in.

That's odd.  Is tcpdump linked with the same version of libpcap as
Ethereal?

I tried running Ethereal with

	udp and port 53

and it captured both DNS requests and replies.  Does "udp and port XXX"
work in Ethereal for other values of XXX, or is the problem limited to
port 162?
