More importantly, I think LBL's excuse is rather lame, considering
that:
(a) tcpdump is available in source form, and anyone can add
ASCII dumps to it fairly easily.
(b) anyone with perms to run tcpdump can trivially write their
own BPF-using program to dump packets in ASCII format.
Bascically, if you don't want people to sniff your wire, make it so
they can't open /dev/bpf*. Since our tcpdump isn't setuid, what's
the problem?
