`snmptrapd`

Receive SNMP TRAP messages

Syntax:

snmptrapd [-d] [-p] [-p port] [-v 1|2]

Options:

-d: Dump input and output packets.
-p: Print messages to standard output.
By default, messages are sent to the system log. In order to capture the log messages, you need to have syslogd running.
-p port: Specify the destination port number.
-v 1|2: SNMP version (default is 2).

The snmptrapd utility receives SNMP TRAP messages sent to the snmp-trap port on the local machine. If you specify -p, snmptrapd prints messages to standard output. The messages are of the form:



------------------------  Notification  ------------------------
10.0.0.59: Cold Start Trap (0) Uptime: 1 day, 6:11:24
system.sysDescr.0 = "SUN 3/60: SUNOS4.0"

You must have superuser privileges when you run snmptrapd.

Environment variables:

MIBFILE

Specify the location of the mib.txt file. For example, MIBFILE=path/mib.txt (the default path is /etc).

If SUFFIX exists in your environment, all object IDs with a symbolic name are printed with only the last element. Examples:

This ID:

system.syscontact.0

is printed as:
