Ok, I see a lot of emails back and forth, and I think it would be good
to summarize:
1. Myself, as well as most of the people answering do not think
that there is a problem with hobbit/xymon itself, but rather with it
being able to query DNS
2. From making point 1 clear, we know the test need to focus on
the machine ability to resolve DNS records, and how it is set on the
configuration for xymon
3. We don’t have information about your DNS server and resolver
settings. This won’t matter much except for a couple of exceptions
a. Windows 2003 DNS will not automatically insert linux host
into the DNS table, so you need to create the A records and reverse
pointers manually.
b. In windows, mainly if you have Exchange running it is
recommended that you also have WINS running (to speed up hostname
lookup), and so WINS is still quite common. Why am I pointing at WINS?
Easily, it is used for query of hostnames, so now there is a
difference into having FQDN and just hostnames in the bb-host file
4. You can setup hosts to be monitored in the bb-host file
either as a hostname, and IP or a FQDN. If possible I use the FQDN.
After all, when you monitor, you want to completely monitor.
a. From this there is something I learn from experience on my
first setup. Using hostnames works with hobbit/xymon, but I did have
problems with some checks not working. This was 5 years ago (My first
test was BB I think actually), but I think the problem test were dns
and ldap
Just to make examples easy, in my bb-host file I have
192.168.11.203
server1.leisure.com # dns ldap
dhcp !ftp !smtp !http://server1.leisure.com DESCR:"server:Active
Directory Server and Application"
And if I run dig, I need to do
Dig server1.leisure.com
And I get the result.
The dns test itself reports
Service dns on server1.leisure.com is OK (up)
Since the test is built into bbtest-net, and we can't duplicate the
problem, and if the person with the issue is sure that a dig on the
server name does work, maybe it's an issue with either the build of
bbtest-net, or with your bb-services file.
Is there any chance you have added a section [dns] to your
etc/bb-services file? I can simulate your problem by adding one (OK,
but no DNS lookup output). If so, please remove it.
