Actually someone has rolled a libpcap and Net-SNMP based RMON module:

Seems quite pre-alpha though.

Good afternoon,
Has anybody heard of or had run tcpdump as a daemon?
If so are there any instructions?
You probably want bpft, not tcpdump.

Hi,
So tcpdump tends to jam up the terminal a bit when you try to dump on
a saturated gigabit link. I've added a -P option to tcpdump that lets
you specify a probability for tcpdump to print each packet. It uses
drand48() to figure out whether each packet captured should be
+1 here.
Zero copy BPF has just gone into FreeBSD-CURRENT. It would be great to
have a snap which can do this too. Christian Peron (CC'd) has been
responsible for the code.

Correct. I believe it logically belongs with pcap, as it is something
which may well be required if using pcap as the link-layer API.

That was my plan.
The tcpdump 3.9.6 archive still appears to contain tcpdump 3.9.5.
Any plans to take this forward? Or a rough time estimate of when

Try capturing rtp/rtcp flows e.g. for Voice-over-IP.

Of course, if you mean dumping sctp traffic in a human-readable manner,
that is quite different.

It would be nice if we could get this committed and
Here's a patch against 5.3 to add a per-instance switch which allows
the user to specify if captured packets should be timestamped (and,
if so, whether microtime() or the faster but less accurate
getmicrotime() call should be used).
