bpft is a superset of trafshow, and extends it by adding a daemon
which collects data about network connections (src, dst, protocol
and length). The resulting data can be dumped to a file for later
processing.
Read /usr/local/share/doc/bpft/README after installation for more
information.
To use bpft, your kernel must be rebuilt with the following line
added to your kernel config file (/sys/i386/conf/<YourMachine>):
pseudo-device bpfilter 4 # Berkeley packet filter
The number after bpfilter is the number of interfaces that can be
examined simultaneously. See section 6.1 of the Handbook for details.
On FreeBSD 4 or later, use the following line instead:
device bpf # Berkeley packet filter
