Install snmpd cara praktis aja ya..
# apt-get install snmpd (linux)
# pkg_add -rv net-snmpd (fbsd)

Stl itu copy file konfigurasi :
# cp /etc/snmp/snmpd.conf.orig /etc/snmp/snmpd.conf (linux)
# cp /usr/local/share/snmpd/snmpd.conf.example /usr/local/share/snmpd/snmpd.conf (bsd)

Edit /etc/snmp/snmpd.conf :
com2sec local localhost public
com2sec local ipmrtgserver public

Edit /etc/default/snmpd : (freebsd ga perlu proses ini)
remove ip 127.0.0.1

Restart snmp : /etc/init.d/snmpd restart
