It is desired to increase security by disabling SNMPv1 and SNMPv2c,
leaving SNMPv3 enabled.


The default configuration permits a community named 'public' read-only
access from the localhost.

It does so through the following configuration line in /etc/snmp/snmpd.conf

rocommunity public

Commenting out this line or removing it altogether will disable this access.

Restart the snmpd daemon.

# /etc/init.d/snmpd restart

After starting snmpd, you can verify that the SNMPv1 and SNMPv2c access
is disabled using the snmpwalk utility:
# snmpwalk -v1 -c public localhost
Timeout: No Response from localhost

# snmpwalk -v2c -c public localhost
Timeout: No Response from localhost
