+.Sh NAME
+.Nm ipfwpcap
+.Nd "copy diverted packets to a file in tcpdump format"
+.Sh SYNOPSIS
+.Nm
+.Op Fl dr
+.Op Fl b Ar maxbytes
+.Op Fl p Ar maxpkts
+.Op Fl P Ar pidfile
+.Ar portnum
+.Ar dumpfile
+.Sh DESCRIPTION
+The
+.Nm
+utility is used to copy diverted packets to a file in
+.Xr tcpdump 1
+format.
+The interesting packets are diverted by
+.Xr ipfw 8
+to a port on which
+.Nm
+listens.
+The packets are then dropped unless
+.Fl r
+is used.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl d
+Turns on extra debugging messages.
+.It Fl r
+Writes packets back to the
+.Xr divert 4
+socket.
+.It Fl rr
+Indicates that it is okay to quit if
+.Ar maxbytes
+or
+.Ar maxpkts
+are reached.
+Diverted packets will silently disappear if nothing is listening on the
+.Xr divert 4
+socket.
+.It Fl b Ar maxbytes
+Stop dumping after
+.Ar maxbytes
+bytes.
+.It Fl p Ar maxpkts
+Stop dumping after
+.Ar maxpkt
+packets.
+.It Fl P Ar pidfile
+File to store PID number in.
+Default is
+.Pa /var/run/ipwfpcap.portnr.pid .
+.El
+.Pp
+The
+.Ar portnum
+argument specifies which
+.Xr divert 4
+socket port to listen on.
+The
+.Ar dumpfile
+argument is the path to the file to write captured packets to.
+Specify
+.Sq Fl
+to write to stdout.
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+.Dl "ipfwpcap -r 8091 divt.log &"
+.Pp
+Starts
+.Nm
+as a background job listening to port 8091 and reflecting the packets
+back to the socket.
+.Pp
+.Dl "ipfw add 2864 divert 8091 ip from 192.0.2.101"
+.Pp
+Example
+.Xr ipfw 8
+rule to divert all packets from 192.0.2.101 to port 8091.
+See
+.Xr ipfw 8
+for details.
+.Sh SEE ALSO
+.Xr tcpdump 1 ,
+.Xr pcap 3 ,
+.Xr divert 4 ,
+.Xr ipfw 8
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Fx 7.0 .
