e. Save the modified property file and exit the gedit utility. 3. Configure the probe to run as a non-root user. If using the default port number for SNMP traps, 162, you must run the probe as the root user. If you do not want to run the probe as the root user, you must either use a different port number for traps, something greater than 1024 or configure the probe to run with setuid. The following steps describe how to configure the probe to run with setuid. a. Change to the root user: su - Password: object00 b. Change the ownership of the probe binary file: cd /opt/IBM/tivoli/netcool/omnibus/platform/linux2x86/probes64 chown root nco_p_mttrapd

Modify the dynamic linker runtime bindings file: cd /etc cp ld.so.conf ld.so.conf.orig gedit ld.so.conf Add the following lines to the bottom of the file: /opt/IBM/tivoli/netcool/platform/linux2x86/lib64 /opt/IBM/tivoli/netcool/omnibus/platform/linux2x86/lib64 e. Save the changes and exit the gedit utility. f. Reload the modified file: ldconfig -v g. Exit the root user back to the netcool user: exit Important: Make sure that you are the netcool user before proceeding. 4. Start the probe as the netcool user. a. Start the probe: nco_p_mttrapd & b. Check the log file for errors: cd $OMNIHOME/log more mttrapd.log 5. Test the probe. The easiest way to test the probe is to generate a specific SNMP trap and verify that the probe sends the correct event to the ObjectServer. a. Log in to Dashboard Application Services Hub as the ncoadmin user. b. Open the Event Viewer. Leave the Event Viewer window open. The MIB Manager utility is bundled with Netcool/OMNIbus.
