34 Setup and Administration
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:
