snmp_traprcv - A program that listens for SNMP trap messages and prints any
/usr/sbin/snmp_traprcv [-d] [-tcp] [-p port]
-d Sends a hexadecimal dump of the received packet to stdout.
Specifies that the TCP transport be used instead of the UDP transport.
If a connection cannot be established, the program silently receives
the trap on the standard transport address (UDP 162).
Specifies the port number on the local host on which to listen to mes-
sages. The default is 162, the well-known SNMP trap port.
The snmp_traprcv program listens on the SNMP Trap port specified in the
/etc/services file. If no entry exists in the /etc/services file, the pro-
gram listens on port 162. If any SNMP trap messages arrive, snmp_traprcv
prints them to stdout. The program runs until terminated by typing Ctrl/c.
When using the default or well-known port, you must have root privileges in
order to run this program. The program may not be able to bind to the
default or specified port if other software on the system is already bound
to that port.
