Hobbit server resolving client name in correctly 🔗 link

I have a new installation of Hobbit 4.2.0 monitoring a private network
(192.158.151.0/24)  It is currently monitoring a number of Windows servers
with BB clients reporting data to hobbit.  The Hobbit system is configured
to use two Windows DC's for DNS resolution.  Hobbit however is reporting in
the CONN column that one of the DC's has a public IP address on the
64.20.33.0/29 network.  How is this happening?  The BBHOST file has the
correct local IP address and FQDN host name.  None of the client specific
data is registering with Hobbit either.
 
If I perform a lookup from the system, the host name resolves correctly to
the private IP address of this box.

So you should look at the resolver settings for your Hobbit server. What
kind of system are you running Hobbit on ?

Hobbit uses the ARES library for DNS lookups, and this does adhere to
some settings controlling what the priority is between any /etc/hosts
file and DNS. Is this host perhaps listed in /etc/hosts ?

You can also try this: Login as the Hobbit user, then run 
  "bbcmd bbtest-net --debug MY.HOST.NAME"
where MY.HOST.NAME is the hostname from the bb-hosts file. You should
see something like this somewhere into the debug output:

2006-09-13 21:59:22 Opening file /usr/lib/hobbit/server/etc/bb-hosts
2006-09-13 21:59:22 Adding hostname 'client3.hswn.dk' to resolver queue
2006-09-13 21:59:22 Got DNS result for host client3.hswn.dk : 127.0.0.1
2006-09-13 21:59:22 Processing 1 DNS lookups with ARES

What does your output say?

None of the client specific data is registering with Hobbit either.

Probably a different problem. Check if the host appears in the "Ghost
clients" report on the Hobbit server; if it does, then the hostname
reported by the client and the hostname you have in the bb-hosts file
don't match (most often, one uses the fully-qualified hostname, and the
other uses the plain hostname with no domain).

Running Hobbit on FC5, installed Hobbit from the RPM packages on
SourceForge, which is a first as I typically have installed "manually".

Hobbit uses the ARES library for DNS lookups, and this does adhere to some settings controlling what the priority is between any /etc/hosts file and DNS. Is this host perhaps listed in /etc/hosts ?

It was not specifically added to /etc/hosts

I'll give this a shot and get back to you.

I also noticed some other odd behavior on this box after sending this
message.  The hobbit server itself was only reporting status on CONN BBD
INFO and TRENDS.  I made some modifications to the BBHOSTS file in
preperation of adding in other systems (created four PAGE groups in
BBHOSTS), but the changes never appeared.  I attempted to restarting Hobbit
from the script, but still no changes to main display, then restarted the
Hobbit Service that was listed in the Services applet.  Pages still did not
display, but the remaining info for the HOBBIT server (CPU, DISK, MEMORT,
etc) suddenly appeared.
