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" 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.

To enable SNMP access from a specific remote host 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:

Find the line that reads:

rocommunity public 127.0.0.1

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

NOTE: You can enable SNMP access from multiple specific remote hosts by adding a rocommunity

directive for each remote host.

To enable SNMP configuration changes, restart the SNMP agent by typing:

/etc/init.d/snmpd restart
