The public community string should but commented out, or if SNMP is a required service the public community name should be changed to be a combination of letters, numbers and special characters to enhance security.

Edit the file:

vi /etc/snmpd.conf

Comment out the public entry:

#community public

Default Value:

Commented in

Additional Information:

Reversion:

Copy back the original /etc/snmpd.conf file:

cp -p /etc/snmpd.conf.pre_cis /etc/snmpd.conf
