I have to add a proprietary MIB to debian's snmpd that I must be able to query (get and set) from another networked computer on a non-standard UDP port (network aspects will be a further step).
I have a MIB file in ~/.snmp/mibs and a perl extension for the agent, that is currently very close to what I could find on the Net. I have modiified the /etc/default/snmp, /etc/snmp/snmp.conf and /etc/snmp/snmpd.conf as understood from various tutorials
SNMP v3 is a constraint so I have created a user following the tutorials available on the Net.
Everything works when I query for example sysUpTime.0. But I cannot access my private MIB:
snmpget says "No Suvh Instance currently exists at this OID" but can give me the name
snmpwalk gives an empy content for the MIB when I ask from the top of my private MIB
snmptranslate says "Unknown Object Identifier (Sub-id not found)"
I don't know if this is sufficient a description for someone to help me. My current belief is that the agent does not know how to answer, but I can't seem to be able to find what prevents it from doing so (the perl sub-agent is registered as read in the tutorials).
The only things I know about SNMP (apart from various interpretations of the acronym, and the fact that once you've understood how it works it 'seems' simple) is what I have found the last days on the Net. thus please forgive if I don't always use the most appropriate terms. Network-wise I am rather a user, other than that I usually develop low-level drivers.
Thanks a lot for any help
Daniel
