#
# This script is a snmp trap handler for use with the NET-SNMP / UCD-SNMP
# snmptrapd program and SNMPTT.
#
# The script is called by defining a 'traphandle' in snmptrapd.conf.
# For example:
#
# traphandle default /sbin/snmptthandler
#
# SNMPTRAPD feeds details about the trap to the launched program's standard
# input in the following format (see snmptrapd.conf man page for a complete
# descriptipon)
#
# HOSTNAME: The name of the host in question that sent the trap
# IPADDRESS: The IP address of the host that sent the trap
# VARBINDS: A list of variable bindings that describe the trap and
# the variables enclosed in it.
#
# SNMPTTHANDLER dumps the received traps into a directory to be processed
# by the SNMPTT daemon.
