# ap-trapd(8)

a SNMP trap processing daemon

## NAME

ap-trapd - a SNMP trap processing daemon

## SYNOPSIS

**ap-trapd** **\[ -i** *device* **\] \[-u** *user* **\] \[-s\]**

**ap-trapd** It's a SNMP trap processing daemon that accepts traps, parse them and store useful data using syslog, at logging LEVEL0. Specify  *device* to listen for SNMP traps on the particular device (this option only works at Linux). To be running by user different from nobody you may specify  *user.*\

 After doing it, just restart syslogd with command like\
\
 	killall -HUP syslogd
