2. Configuration

Move existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.copy

mv /etc/snmp/snmpd.conf  /etc/snmp/snmpd.conf.copy

Create a new /etc/snmp/snmpd.conf file:

rocommunity  public

syslocation  "Branch Office"

syscontact  systems@domain.com

Make snmpd use the newly created file and make it listen to all interfaces:

Edit /etc/default/snmpd file for giving reference to snmpd.conf file

user@server# sudo nano /etc/default/snmpd

Change from:

# snmpd options (use syslog, close stdin/out/err).

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

To:

# snmpd options (use syslog, close stdin/out/err).

#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 -c /etc/snmp/snmpd.conf'

3 Restart snmpd service
