SNMP manager problem in handle_register_agent/4

[karol skocik]

Hi dear Erlangers!
  I am having an obscure problem with SNMP manager. I have developed a
SNMP agent application in Erlang couple months ago (my first Erlang
app!! hopefully not last :-), and now, at the time of integration and
internal testing, I am not able to make the manager running for
testing of the agent. I have tried many times a configuration changes
with snmp:config(), dumbing SNMP to v1 with no security (not really
usable for us, but to achieve a minimum functionality), and also I
have tried trapexit's howto, but no luck so far. I am quite puzzled,
since I think I didn't change anything in the process of
configuration, but since no other Erlang user is signalling problems
with the manager, it seems that the problem must be on my side.

When I start erl with config files for manager, and I do
application:start(snmp) I get immediately a very badly formated error
(because it was stringified), which after unstringing and some
indentation looks like this :

md@REDACTED ~/md_projects/snmp/manager $ ./run_manager
Erlang (BEAM) emulator version 5.4.13 [source] [hipe]

Eshell V5.4.13  (abort with ^G)
(manager@REDACTED)1> application:start(snmp).

I am running on :

GNU/Linux

The config files (the paths must be changed) are in the attachment, I
hope somebody with the Erlang SNMP knowledge will take a look at that,
and tell the rookie what is the problem. (And help spreading Erlang in
our company & beyond ;-)

Thanks for your time,
