Summary: check_nwstat generates ipv6 calls (error)

Initial Comment:
Short story :

check_nwstat is doing 2 X AAAA request and 1 X A
request to my DNS server since version 1.3.99 (1.13).

Details and tests :
Linux server RedHat9. DNS server Netware

With check_nwstat v1.3.99 or more recent, my DNS server
is showing that my Nagios server is doing 2 X AAAA
request (ip6) and 1 X A request (ip4).

I tested with version 1.3.1 of the plugins, and there
is no problem there. (but features in latest release
are needed).

I tested with other plugins and with ping, and
everything is fine.

Here is a peace of the logs.

Unassigning from Karl, but not sure of current status of this bug. Is it 
still an issue with the latest release?

Hi kdebisschop,

I have tryed your check_nwstat of 2004-02-29.
I can compile it, I can run it, but there is no output.

And, on my dns, there is no dns request been made.

And here is the command call that I use. Any other variable
could be used. The output is working with 1.3.1 or 1.4.1alpha.
./check_nwstat -H srv-ndps1.cslaval.qc.ca -v ABENDS

The answer to this command is usually: "0 abended threads"

srv-ndps1 is an internal server. So you can't access it. But
I can make any tests you require. Thanks.

I may have found the cause - we were opening a new
connection for each attribute requested. I have rewritten
the code to open one connection and send repeatedly on tha
one connection. But I do not have any way to test it and I
do not know if the NW protocols allow it. Please test and
provide feedback.

Can you provide the service and command definitions that
create these multiple requests? I don't have access to a
test environment, but I'll be glad to look at the code and
see if I can find anything.
