Question & Answer
Question
In the probe's log file, below error messages can be seen:
SNMP Message (priority=3): UDP snmp_open: Unknown host (udp:162) (Permission denied)
Error: E-UNK-000-000: Failed to open UDP session
Error: E-UNK-000-000: Unable to get hold of session link pointer
Error: E-UNK-000-000: Failed to open UDP session
Error: E-UNK-000-000: Unable to get hold of session link pointer
Cause
The non-root users do not have permission to open port 162.
Answer
The probe can also be run as non-root with a port greater than 1024 or the probe can be run as root with the standard port 162.
It is recommended the following in order to fix the issue:
1. As root, change the owner of the probe binary using chown root nco_p_mttrapd. (in $OMNIHOME/probes/arch directory.)
2. As root, enable the probe binary to run as setuid root, using chmod +s nco_p_mttrapd. ( in $OMNIHOME/probes/arch directory.)
3. Make sure you have set NCHOME and OMNIHOME environment variable.
4. Go to /opt/IBM/tivoli/netcool/omnibu
Verify that all the libraries are in place.
