Default VACM model
The default configuration of the agent, as shipped, is functionally
equivalent to the following entries:
com2sec public default public
group public v1 public
group public v2c public
group public usm public
view all included .1
access public "" any noauth exact all none none
SNMPv3 CONFIGURATION
engineID STRING
The snmpd agent needs to be configured with an
engineID to be able to respond to SNMPv3 messages.
With this configuration file line, the engineID
will be configured from STRING. The default value
of the engineID is configured with the first IP
address found for the hostname of the machine.
createUser username (MD5|SHA) authpassphrase [DES] [priv-
passphrase]
This directive should be placed into the "/var/ucd-
snmp"/snmpd.conf file instead of the other normal
locations. The reason is that the information is
read from the file and then the line is removed
(eliminating the storage of the master password for
that user) and replaced with the key that is
derived from it. This key is a localized key, so
that if it is stolen it can not be used to access
other agents. If the password is stolen, however,
it can be.
MD5 and SHA are the authentication types to use,
