No SNMP Response from < ip address >

This document (3000812) is provided subject to the disclaimer at the end of this document.

Environment

Novell SUSE Linux Enterprise Server 9
Simple Network Management Protocol
snmpd daemon

Situation

No SNMP Response from < ip address > when running snmp query against SLES 9 server.
SLES 9 default settings do not respond to public community string query from SNMP mib browser.
/var/log/net-snmp.log lists client connections but does not show successful snmp client queries.

Resolution

There are two ways to resolve the symptom:

A- The quick way is to open the /etc/snmpd.conf file and remove the loopback address entry (127.0.0.1) from the rocommunity public line and restart the snmp daemon, then run the snmp mib browser agsinst the SLES server.

B- The recommended way is to run snmpconf on the SLES server running the snmpd daemon:
1. Type: snmpconf
Note: See the man page for snmpconf. snmpconf is a perl script utility that configures basic snmp settings. More verbose snmp settings can be configured by typing: snmpconf -g basic_setup.
2. Type: all (to read in and merge the snmp configuration files).

3. Select option 1 (to create snmpd.conf).

4. Select option 1 (Access Control Setup).

5. Select option 3 (to setup a read-only access community).

5a. Type: public (the community name that will have read-only access is "public")

5b. Press the RETURN key (or press the Enter key to allow all hosts and network addresses to access the public access community).

5c. Press the RETURN key (or press the Enter key to not restrict the public access community to any specific OID).

6. To set up a read-write access community, select option 4 and repeat steps 5a-5c above by providing the appropriate information.

7. Type: finished

8. Type: finished

9. Type: quit

10. Type: cp /etc/snmpd.conf /usr/share/snmp (to copy the snmpd.conf created by the snmpconf utility to the /usr/share/snmp folder so the snmp configuration can be used by everyone on the system).

11. Type: rcsnmpd restart (to restart the snmpd daemon).

12. Run the snmp mib browser against the SLES server
