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. Since the 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
