RE: Stuck in the way of quering a private MIB (extension using perl)

Hi,

 

Sorry if I posted twice the other day, I thought the first post didn't get through.

 

Anyway, is there no-one who can give me even some slight advice about what to look for? 

 

I have been asked to finish this in the coming days, but as said I know nothing about the lot.

 

Thanks

 

Daniel

Objet : Stuck in the way of quering a private MIB (extension using perl)

 

Hi all,

 

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 exemple 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 : (top)"

 

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
