Setup and Administration 31
The second change is to modify the default "access" line to give read-only
access to the entire MIB tree for the "public" community. Server
Administrator looks for the following line:
access notConfigGroup "" any noauth exact systemview
none none
If Server Administrator finds the line above, it modifies the line so that it reads:
access notConfigGroup "" any noauth exact all none none
These changes to the default SNMP agent configuration give read-only access
to the entire MIB tree for the "public" community.
NOTE: To ensure that Server Administrator is able to modify the SNMP agent
configuration to provide proper access to systems management data, it is
recommended that any other SNMP agent configuration changes be made after
installing Server Administrator.
Server Administrator SNMP communicates with the SNMP agent using the
SNMP Multiplexing (SMUX) protocol. When Server Administrator SNMP
connects to the SNMP agent, it sends an object identifier to the SNMP agent
to identify itself as a SMUX peer. Because that object identifier must be
configured with the SNMP agent, Server Administrator adds the following
line to the SNMP agent configuration file, /etc/snmp/snmpd.conf, during
installation if it does not exist:
smuxpeer .1.3.6.1.4.1.674.10892.1
Changing the SNMP Community Name
Configuring the SNMP community names determines which systems are able
to manage your system through SNMP. The SNMP community name used by
management applications must match an SNMP community name configured
on the Server Administrator system so that the management applications can
retrieve management information from Server Administrator.
To change the SNMP community name used for retrieving management
information from a system running Server Administrator, edit the SNMP agent
configuration file, /etc/snmp/snmpd.conf, and perform the following steps:
