Setup and Administration 29
Configuring Your System to Send Traps to a Management Station
Server Administrator generates SNMP traps in response to changes in the status of sensors and other
monitored parameters. One or more trap destinations must be configured on the system running Server
Administrator for SNMP traps to be sent to a management station.
To configure your system running Server Administrator to send traps to a management station, edit the
SNMP agent configuration file, /etc/snmp/snmpd.conf, and perform the following steps:
1
Add the following line to the file:
trapsink IP_address community_name
where IP_address is the IP address of the management station and community_name is the
SNMP community name
2 To enable SNMP configuration changes, restart the SNMP agent by typing:
service snmpd restart
Configuring the SNMP Agent on Systems Running Supported SUSE LINUX Enterprise Server
Operating Systems
Server Administrator uses the SNMP services provided by the ucd-snmp or net-snmp agent. You can configure
the SNMP agent to enable SNMP access from remote hosts, 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 about SNMP configuration.
Sever Administrator SNMP Install Actions
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. This object identifier must be configured
with the SNMP agent, therefore, Server Administrator adds the following line to the SNMP agent
configuration file, /etc/snmpd.conf, during installation if it does not exist:
smuxpeer .1.3.6.1.4.1.674.10892.1
Enabling SNMP Access From Remote Hosts
The default SNMP agent configuration on SUSE LINUX Enterprise Server operating systems gives read-
only access to the entire MIB tree for the "public" community from the local host only. This configuration
does not allow SNMP management applications such as IT Assistant running on other hosts to discover and
manage Server Administrator systems properly. If Server Administrator detects this configuration during
installation, it logs a message to the operating system log file, /var/log/messages, to indicate that SNMP
access is restricted to the local host. You must configure the SNMP agent to enable SNMP access from
remote hosts if you plan to manage the system by using SNMP management applications from remote hosts.
NOTE: For security reasons, it is advisable to restrict SNMP access to specific remote hosts if possible.
