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.
