interaction with management applications such as IT Assistant, perform the procedures described in the
following sections.
NOTE: For additional details on SNMP configuration, see the operating system documentation.
Sever Administrator SNMP Install Actions
Server Administrator SNMP communicates with the SNMP agent using the 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/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/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.
NOTE: You can enable SNMP access from multiple specific remote hosts by adding a
rocommunity directive for each remote host.
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/snmp/snmpd.conf, and perform the following steps:
4. Find the line that reads: rocommunity public 127.0.0.1.
5. Edit this line by deleting 127.0.0.1. When edited, the new line should read: rocommunity public.
6. To enable SNMP configuration changes, restart the SNMP agent by typing: /etc/init.d/snmpd
restart
.
Changing The SNMP Community Name
Configuring the SNMP community name determines which management stations are able to manage
your system through SNMP. The SNMP community name used by management applications must match
the SNMP community name configured on the system running Server Administrator,, so the management
applications can retrieve the management information from Server Administrator.
