To enable SNMP Set operations on the 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: access publicgroup "" any noauth exact all none none or access
notConfigGroup "" any noauth exact all none none.
2. Edit this line, replacing the first nonewith all. When edited, the new line should read: access publicgroup
"" any noauth exact all all none or access notConfigGroup "" any noauth exact
all all none.
3. To enable SNMP configuration changes, restart the SNMP agent by typing: service snmpd restart.
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
Server Administrator uses the SNMP services provided by the 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: 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.
