Server Administrator SNMP Agent Install Actions
If Server Administrator detects the default SNMP configuration during installation, it attempts to modify the SNMP agent configuration to give read-only access
to the entire MIB tree for the "public" community. Server Administrator modifies the /etc/snmp/snmpd.conf SNMP agent configuration file in two ways.
ThefirstchangeistocreateaviewtotheentireMIBtreebyaddingthefollowinglineifitdoesnotexist:
view all included .1
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.
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softwaresystem,so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:

1. Find the line that reads:
com2sec publicsec default public
or
com2sec notConfigUser default public

2. Edit this line, replacing public with the new SNMP community name. When edited, the new line should read:
com2sec publicsec default community_name
or
com2sec notConfigUser default community_name

3. To enable SNMP configuration changes, restart the SNMP agent by typing:
service snmpd restart

Enabling SNMP Set Operations
SNMP Set operations must be enabled on the system running Server Administrator in order to change Server Administrator software attributes using IT
Assistant. To enable remote shutdown of a system from IT Assistant, SNMP Set operations must be enabled.
To enable SNMP Set operations on the system running Server Administrator, edit the /etc/snmp/snmpd.conf SNMP agent configuration file and perform the
following steps:

1. Find the line that reads:
access publicgroup "" any noauth exact all none none
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.
NOTE: Rebooting your system for change management functionality does not require SNMP Set operations.
