1) Here is the output I get when using the -Le option:
[EMAIL PROTECTED] net-snmp]# /export/home/myname/snmp/usr/local/sbin/snmpd -f
-Le &
[1] 27644
[EMAIL PROTECTED] net-snmp]# Turning on AgentX master support.
Error: Couldn't open a master agentx socket to listen on ():
Obviously I am not configured correctly .... what am I missing?
2) Currently, I am using the snmpd master agent to process my "OC-STB-HOST-MIB"
MIBfile. I am using the MfD configuration framework and have multiple
directories where my code is located:
.../agent/mibgroup/OC-STB-HOST-MIB/ocStbHostAnalogVideoTable/
.../agent/mibgroup/OC-STB-HOST-MIB/ocStbHostAVInterfaceTable/
.../agent/mibgroup/OC-STB-HOST-MIB/ocStbHostComponentVideoTable/
etc..
etc..
** Each directory represents a "Table" defined in the MIB.
Now, I would like to create a subagent to handle this MIB file (instead of the
snmpd master agent) and I am not sure how to go about doing this. I have
multiple directories which contain code for this MIB and I am not sure how to
create the subagent. Must I create an "example-demon.c" similiar type file for
each of the tables and edit it was specific MIB information somehow?
Basically, I am confused as to what the tutorial is showing me. In the
tutorial, I simply perform a "make" on a "example-demon.c" file and suddenly I
have a subagent which can be executed by issuing the "example-demon" command.
I do not understand what table files I need to perform a "make" on to suddenly
get a useable subagent for my own code. Hopefully I do not have to create a
subagent for each table in my MIB.... correct?
Any insight here would be appreciated. I clearly do not understand how to
relate what the tutorial is showing me to my own MIB code in order to produce a
subagent which can handle my MIB.

It doesn't matter.
The whole point of a standalone subagent is that it's standalone.
It doesn't depend on the rest of the source tree.
As long as you've got the Net-SNMP suite installed, the
Makefile will pick up the headers and libraries from their
installed locations.

Does it produce any error messages?
Try running it as
/export/home/myname/snmp/usr/local/sbin/snmpd -f -Le
What does it display?

The file 'example-demon.c' is the framework for an AgentX subagent.
This is basically equivalent to the framework that
net-snmp-config --compile-subagent
will generate.
This is then linked together with the code from 'nstAgentSubagentObject.c',
which is where the NET-SNMP-TUTORIAL-MIB.txt stuff is implemented.
These two code files are compiled and linked together to produce the binary
'example-demon'

Because there are two (or more) code files that are compiled into the
example-demon binary - not just example-demon.c.
Try watching what happens when you run "make"
