Summary: SNMP for Embedded LynxOS

Initial Comment:
firstly I would like to say that I am more of a 
software developer mainly in Ada with some C rather 
than a network engineer and I find this task is 
stretching the "grey matter" in an interesting 
direction.

I therefore apologise in advance if any of my comments 
seem odd but this is a new area to me and I am still 
finding my way.

After reading the manuals section "Extending the UCD-
SNMP agent" I think I more or less understand  the 
approach described but this is targeted to an 
'install' of the SNMP on top of the host OS.

The same can be said for all the other documents I 
have found.

To give you some idea of the scenario;

(a) An American company generated a MIB text file 
which runs to some 125 pages to manage a data modem 
and used this in a windows development environment.

There are a .h and .c file of the same name but they 
do not have the same style as the C files in the 
.../mibs directory(they contain functions to put/get  
etc).

(b) I am now to port this onto a Power PC card running 
LynxOS 3.0.1 which is to manage the modem on a carrier 
also fitted to the card.

(c) As a first stage I am generating a Solaris 
implementation and although I generated the config.h 
and compiled it with the files mostly from snmplib 
directory I am at a point where I don't know what I 
have but the object library generated in my 
development environment(Rational Apex Duo) links with 
my Ada code.

What I see is two things;

1. I need to understand if it is possible to link SNMP 
C code with my Ada code and have it working.
    If so, then I also need to understand how to 
perform the basic tailoring to achieve this.

While writing this email my feeling is that this 
option would not be correct and I should adopt the 
following approach(2). - any comment

2. Whether the SNMP needs to be always installed on 
top of the host OS and if so how to do this from an 
embedded (automated) perspective and to tailor it for 
the environment requirements. If this approach is to 
be taken then I will also need to understand how to 
talk to it from my application.

Maybe I need to load the SNMP source onto a card 
running LynxOS, generate the config.h and try to 
install it. I could then try to see what needs to be 
included when I build my kernel image (.kdi) ...

If anyone were able to provide info or references 
where I can do more research then I would be most 
grateful.

The source is ucd-snmp Version 4.1.2

Thanks,

Chris
