<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal">I have a problem with my Xymon setup I
haven’t been able to get around. The conn test for servers at
the same site as the Xymon server that have simple host name
entries in bb-hosts fails about every 2.5 minutes with a
“Can't resolve IP address for 1091edudc01” error (1091edudc01
being the host name). The other hosts at this site with FQDN
work fine, as do simple host names at other sites. </p>
</div>

Such random DNS lookup problems usually happen if your DNS server
cannot quite cope with the burst of requests that Xymon generates.
Are you using a local caching DNS server on the Xymon server, or the
usual one for your other systems?<br>
<br>
I really do recommend installing a caching DNS server on the Xymon
server - I've seen Xymon bring DNS servers to their knees easily.<br>

<p class="MsoNormal">Added “testip” to bb-hosts<o:p></o:p></p>

These two - in combination! - will force Xymon to use the IP from
the hosts.cfg (bb-hosts) file and avoid the DNS lookup. So that
should solve it.<br>
