Description Bradley 1999-04-07 02:23:34 EDT
Using tcpdump with a filter, on the loopback interface
doesn't match any packets.

Using -i lo, without a filter, or -i ppp0 port 23 does work,
returing the requested packets, but

~# /usr/sbin/tcpdump -i lo port 23

doesn't (using src or dst rather that port doesn't work
either)
