Have you run "ldconfig" to tell the linker about this library?

What access control settings are you using?

Which mib2c framework are you using?
There are various options, and the code produced looks very different
in each case.

The fragment you posted isn't really sufficient to see what's happening.

It's not particularly clear what you mean by this.
What do you mean by "parameters" in this context?

If you're sending information from the agent, then this message must
take the form of a notification (i.e. a trap) - which *must* be defined
as a NOTIFICATION-TYPE object.
   However this trap can take a list of "normal" objects as the payload
for the trap, so it's perfectly valid (and usual) to include such values
as *part* of the trap - but not "instead" of it.

What does the code that implements this object look like?

I'm sorry, but that's not really enough for us to work with.
If you're still having problems, then you'll need to give us more
details about exactly what you've tried, and what problems
you are seeing.

Terminate and restart sending a 2 to 1.3.6.1.4.1.6827.10.74.3.9.1.1.2 works then subsiquent SETs to 1.3.6.1.4.1.6827.10.74.3.9.1.1.2 will fail, however I can send 1..7 to 1.3.6.1.4.1.6827.10.74.3.2.1.1.2 without problem.

This was net-snmp 5.2.1 ( standard Apple install ) 5.4 acts the same.

Thanks for looking into this Dave, I haven't been subscribed for long but I can tell your busy.

Can you try posting a dump of a request that works, and a dump of one
that fails. (Preferably using the same OID for each).
   That might help indicate what might be going on.

Dave

I had rocommunity6 public defined in snmpd.conf.

The changes Magnus made (16455) fixed the problem. I can now do a 
snmpwalk using the commands above. I tested this with V5-4-patches.

Justin, have you tried with the latest code in V5-4-patches?

Dave, I had to put an #ifndef WIN32 around the feature code 1041888 in 
read_config.c:

if (!S_ISDIR(statbuf.st_mode)) {
..
..
}

Windows doesn't have S_ISDIR. We need a proper fix, but that allowed me 
to compile to test IPv6.

Alex
