Question

When I execute altisnmpd, I get the error message: "Error: Failed to connect to the agentx master agent: Unknown host (Connection refused)".

Answer

Verify that the snmpd daemon is running.

If so, use the altisnmpd -x option to check whether the IP and port are correct.

Question

When I execute the snmpget and snmpwalk commands, I get the error message: "No Such Object available on this agent at this OID".

Answer

This error can occur if altisnmpd and snmpd are not communicating correctly.

Verify that altisnmpd is running. If the user restarted snmpd, altisnmpd must also be restarted.

Question

When I execute the snmpset command, I get the error message: "Error in packet. Reason: notWritable (that object does not support modification)...".

Answer

This error can occur if the value for a read-only object has been set. If it is a read-write object, this is a network problem. In this case, refer to the manual.

Question

When I execute the snmpget and snmpwalk commands, I get the error message: "No Such Instance currently exists at this OID".

Answer

This checks whether the name for an OID or object is saved correctly. The user can view Altibase MIB information with the snmpwalk command.

ex> snmpwalk -v 2c -c private IP:PORT altibase

Also, verify that Altibase is running.

Question

When I execute the snmpget and snmpwalk commands, I get the error message : "Unknown Object Identifier (Sub-id not found: (top) -> xxx)"

Answer

Verify whether the OID name or the object name has been properly specified.

If the ALTIBASE-MIB.txt file cannot be loaded, check whether the file exists in \$MIBDIRS and then check that $MIBS is set to ALL.

Question

When I execute the snmpwalk command, the entire ALTIBASE MIB is not output.

ex> snmpwalk -v 2c -c private IP:PORT altibase
ALTIBASE-MIB::altiPropertyIndex.1 = INTEGER: 1
ALTIBASE-MIB::altiStatusIndex.1 = INTEGER: 1  

Answer

Verify that Altibase is running.
