I think that's somewhat misleading.
In the current configuration, you need to install two packages
(snmpd and quagga) - agreed. In your proposed configuration,
you'd still need to install two packages - quagga, and the snmpd
module.
This feels like essentially the same software requirements.
You're just changing the relationship between them.
Another thing that's not immediately clear to me is the range
of information that you'll need this combined system to handle.
Are you looking at *just* reporting the routing-related information,
or would the agent module still handle all the other data (network
statistics, running and installed software, disk and hardware info,
etc, etc) ?
In answer to your original question:
> Is it posible to extract snmpd of the Net-Snmp ?
The code for the agent is to be found within the 'agent' subdirectory
of the source tree. Note that you'll also need the code under 'snmplib',
which is the core SNMP library.
Plus some way of selecting the appropriate code files for the particular
architecture that you are targeting - this is currently handled by the
Net-SNMP 'configure' script, but I strongly suspect that Quagga will
itself come with a configure script already.
I would agree with Steve that this is not a particularly sensible approach.
But if you're determined to go down this route, then you should probably
start by looking at the code in 'agent/snmpd.c'. This is the file that
handles the specifics of running the agent as a standalone daemon,
including the main event loop.
You'll need to construct an equivalent structure that fits into the Quagga
module framework, which listens for incoming requests on port 161,
and then call 'snmp_read' (or similar). This should then invoke the
normal agent handling code, and everything else should flow as before.
Good Luck (You'll need it!)
