tcpdump port xx bug ?

[Axel Gonzalez]

is anyone able to confirm or deny this (before a PR is filled)?

# tcpdump port xx

doesnt seem to work:

su-2.05b# tcpdump port http
tcpdump: WARNING: rl0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on rl0, link-type EN10MB (Ethernet), capture size 68 bytes
^C
0 packets captured
503 packets received by filter
0 packets dropped by kernel


if no port is specified, it works fine:

su-2.05b# tcpdump | grep freeb
tcpdump: WARNING: rl0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on rl0, link-type EN10MB (Ethernet), capture size 68 bytes
