You are right about the plug-ins. Following the example in the wiki, I was able to compile the snmpd agent and have it respond to a custom mib-node entry.
The idea of snmp sub-agents comes from the SNMP protocol itself, I believe. You need those extra sub-agents on a system to respond to requests/queries that target a device that doesn't support the TCP protocol. Wait, I think I'm explaining this wrong, but essentially, if you have a device such as a fax machine (or something) that you need to configure via SNMP, but it can't be connected to the network directly (no ethernet ports). So, you connect it to a PC and run a SNMP sub-agent on the PC. That way, if any SNMP-manager wants to talk to the fax, the request will get picked by the the sub-agent running on the PC and it will do the needed 'talking' with the fax machine and respond back in its place. You're better off reading a good SNMP book about this, but I think I have the gist of things explained. Hoping someone will correct me if I'm wrong, Abraham Varricatt On Wed, Sep 8, 2010 at 12:13 PM, Ravi Kumar <[email protected]> wrote: > Hi All, > > Could any one plz give me an example in which we need a separate snmp > sub-agent. > I have an snmp agent "snmpd" why do i need to write and extra sub-agent > module. > We can write plug-ins for agent itself to add more mib functionalies in it. > > > Regards, > Ravi > > ------------------------------------------------------------------------------ > This SF.net Dev2Dev email is sponsored by: > > Show off your parallel programming skills. > Enter the Intel(R) Threading Challenge 2010. > http://p.sf.net/sfu/intel-thread-sfd > _______________________________________________ > Net-snmp-coders mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/net-snmp-coders > ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
