mDNSNetMonitor(8) BSD System Manager's Manual mDNSNetMonitor(8)
NAME
mDNSNetMonitor -- dumps mDNS traffic on a network
SYNOPSIS
mDNSNetMonitor [-i interface] [host]
DESCRIPTION
mDNSNetMonitor prints out a description of the contents of mDNS packets
on a network interface. It is similiar to tcpdump in that it continuously
captures packets until it is interrupted by a SIGINT signal (generated,
for example, by typing your interrupt character, typically control-C)
or a SIGTERM signal (typically generated with the kill(1) command).
When mDNSNetMonitor finishes capturing packets, it will report counts of
packets captured per mDNS packet type, service type and source device.
Note that mDNSNetMonitor will not capture unicast mDNS packets.
OPTION
-i interface Displays packets on specified interface.
Example
To print all packets arriving at or departing from sundown:
% mDNSNetMonitor sundown
