Purpose

If you have ever installed the snmpd package for Debian or Ubuntu and wondered why it did not bind to all active interfaces no matter what configuration you have, here is the solution.

Procedures

1. You need to modify the “/etc/defaults/snmpd” file and remove the reference to 127.0.0.1 in the startup command to allow it to fall back to defaults. This was put in as a security measure, but there are very valid reasons to remove it.
2. Change the following in the “/etc/defaults/snmpd” file.

SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1′

SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid’
