Unknown engine ID
Greetings snmp users. I have configured my snmpd.conf file to use snmpv3, and I ran tests using snmp commands to verify that the snmpget and snmpwalk commands retrieve the requested data from the appropriate MIBs. However, I am encountering a situation where the engine ID seems to be getting dropped or lost after a short period of time (2 to 5 minutes). Since it is not always the same time period, it would not appear to be a coded timeout value. I did not specify an engine ID in the snmpd.conf file because I read that that is not the recommended procedure. So snmp should be generating the engine ID with its algorithm. Please see the snmpget commands below. The timeticks display the number of seconds following the startup of the snmpd daemon. Once the Unknown engine ID msg is returned, the only way to get snmp to process commands again is to restart the snmpd daemon. - /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (4555) 0:00:45.55 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (8348) 0:01:23.48 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (19107) 0:03:11.07 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (21359) 0:03:33.59 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (22596) 0:03:45.96 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (24334) 0:04:03.34 /etc snmpget hostname sysUpTime.0 snmpget: Unknown engine ID (Sub-id not found: (top) - sysUpTime) - Does anyone have ideas about what is causing the engine ID to get lost?

RE: Unknown engine ID
From: Cardoza, Eric D. [mailto:[EMAIL PROTECTED] Sent: Friday, November 14, 2008 9:55 AM Hello Mr. Ayers. Talk to the list, not the individual, please. The only tool is net-snmp. net-snmp is not a tool - it is a collection of tools. As you see from the information in my email, I am using snmp commands such as snmpget or snmpwalk to query the MIBs. For a few minutes after I start the snmpd daemon on the system which I am querying, the snmp commands return OID data. Then after a few minutes, I get the Unknown engine ID msg. I must then stop and restart the snmpd daemon on the target system for the snmp commands to retrieve data again. I am not using any external software product in this test. H - this is *very* strange and should never happen - the engineID should be a constant for an engine. Can you please submit details for the installation: - what OS are you running on? - where did the build come from? - Are you explicitly setting the engineId in snmpd.conf? That's a start...
