Non-root users will not be able to capture packets on the client, no
matter what libpcap-based application they use (tcpdump, Ethereal, etc.)
or even if they use the non-libpcap-based snoop, because they don't have
access to the device file they need to open in order to capture packets.

If even root can't capture packets on the client with, for example,
snoop, the problem is somewhere below where Ethereal can deal with it;
you should ask Sun about that.
