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.
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. Because that object identifier must be configured with the SNMP
agent, Server Administrator adds the following line to the SNMP agent configuration file, /etc/snmpd.conf or /etc/snmp/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"
communityfromthelocalhostonly.ThisconfigurationdoesnotallowSNMPmanagementapplicationssuchasITAssistantrunningonotherhoststodiscover
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.
ToenableSNMPaccessfromaspecificremotehosttoasystemrunningServerAdministrator,edittheSNMPagentconfigurationfile,/etc/snmpd.conf
or /etc/snmp/snmpd.conf, and perform the following steps:
1. Find the line that reads:
rocommunity public 127.0.0.1
2. Edit or copy this line, replacing 127.0.0.1 with the remote host IP address. When edited, the new line should read:
rocommunity public IP_address
3. To enable SNMP configuration changes, restart the SNMP agent by typing:
/etc/init.d/snmpd restart
To enable SNMP access from all remote hosts to a system running Server Administrator, edit the SNMP agent configuration file, /etc/snmpd.conf
or /etc/snmp/snmpd.conf, and perform the following steps:
1. Find the line that reads:
rocommunity public 127.0.0.1
2. Edit this line by removing 127.0.0.1. When edited, the new line should read:
rocommunity public
NOTE: On SUSE Linux Enterprise Server (version 9), the SNMP agent configuration file is located at /etc/snmpd.conf. On SUSE Linux Enterprise Server
(version 10), the SNMP agent configuration file is located at /etc/snmp/snmpd.conf.
NOTE: See your operating system documentation for additional details about SNMP configuration.
NOTE: For security reasons, it is advisable to restrict SNMP access to specific remote hosts if possible.
NOTE: You can enable SNMP access from multiple specific remote hosts by adding a rocommunity directive for each remote host.
