I am having a problem I just can not figure out with snmptrapd. I simply
wrote traphandler script to echo Hello World out to the screen when a
certain trap is detected.
Is that *all* that the trap handler does?
Does it try to read the list of trap varbinds which 'snmptrapd'
will pass to it?

No - the size of the installation will be *larger* if shared libraries
are not used. That's because every application will need to include
a separate copy of the library - statically linked in.

Which MIB object are you referring to?
I'm really sorry. I forgot to specify which MIB object I'm interested in.
I'm refering to one I have created to do some testing. But I don't know
where the handler for that object would be located.
If this is a MIB object that you created to do some

Add a 'disk' entry into your snmpd.conf file.

More particularly, the dump begins:

So the request is being sent with an empty community string

My confusion is now on how to utilize the var binds that snmptrapd is

You don't need to actually use any of them.
The trap daemon doesn't care what happens *inside* your handler.
is it enough to just read them in and echo

I have sent traps in using a pthread. No problem. Are you trying to free a
PDU that has not been malloc?
Segmentation faults are usual candidates (using the the political term) for
bad memory accesses.
So your pointer may be invalid? Can you dump out what you allocate and what
you free?

I have extended the net-snmp agent with my own module. It contains scalars,

Title: a question about files generated by mib2c..
Dear all:
I use mib2c tool to generate one C code with ucd-snmp old api ,the smi file as follow:
{ABC-SMI DEFINITIONS ::= BEGIN
IMPORTS
enterprises
FROM RFC1155-SMI;
abc OBJECT IDENTIFIER ::= { enterprises1234 }
abcSamplesOBJECT
From what I can see, I don't see anything about diskIO. I see disk usage,
but nothing about IO.
I have disk entries, but whenever I try to get IO, the search returns
nothing. Does not return No such Object, just returns nothing.

Will it make it into the 5.2 final release?

Here is an example of a trap received at the SNMP management station from
the SNMP agent which reports an IP of 127.0.0.1. Also, 4 traps instead of
the expected 1 trap (with identical time stamp).
