30 Setup and Administration
Configuring the SNMP Agent on Systems Running Supported Red Hat
Enterprise Linux
Server Administrator uses the SNMP services provided by the net-snmp
SNMP agent. You can configure the SNMP agent to change the community
name, enable Set operations, and send traps to a management station. To
configure your SNMP agent for proper interaction with management
applications such as IT Assistant, perform the procedures described in the
following sections.
NOTE: See your operating system documentation for additional details on SNMP
configuration.
SNMP Agent Access Control Configuration
The management information base (MIB) branch implemented by Server
Administrator is identified by the Object Identifier (OID) 1.3.6.1.4.1.674.
Management applications must have access to this branch of the MIB tree to
manage systems running Server Administrator.
For Red Hat Enterprise Linux and VMware ESXi 4.0 operating systems, the
default SNMP agent configuration gives read-only access for the public
community only to the MIB-II system branch (identified by the 1.3.6.1.2.1.1
OID) of the MIB tree. This configuration does not allow management
applications to retrieve or change Server Administrator or other systems
management information outside of the MIB-II system branch.
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:
