snmp_traprcv(8) 					      System Manager's Manual						   snmp_traprcv(8)

NAME
snmp_traprcv - A program that listens for SNMP trap messages and prints any it receives SYNOPSIS
/usr/sbin/snmp_traprcv [-d] [-tcp] [-p port] OPTIONS
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 messages. The default is 162, the well-known SNMP trap port. DESCRIPTION
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 program 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. RESTRICTIONS
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. SEE ALSO
Commands: snmpd(8), snmp_request(8), snmp_trapsnd(8) snmp_traprcv(8)
