<P><FONT SIZE=2>I am using Nagios 1.0b5. I monitor several hosts that are behind firewalls</FONT>
<BR><FONT SIZE=2>and therefore are un-pingable. Because of this Nagios reports that the</FONT>
<BR><FONT SIZE=2>hosts are down. In Netsaint configs you could simply not include the</FONT>
<BR><FONT SIZE=2>check_host_alive directive to skip ping check. According to the docs for</FONT>
<BR><FONT SIZE=2>Nagios, when using the new template based config for the hosts.cfg file I</FONT>
<BR><FONT SIZE=2>should be able to leave the check_command field blank to skip any host</FONT>
<BR><FONT SIZE=2>checking. This fails when starting the Nagios configuration check with the</FONT>
<BR><FONT SIZE=2>following error:</FONT>
</P>
<P><FONT SIZE=2>Reading configuration data...</FONT>
</P>
<P><FONT SIZE=2>Error: NULL variable value in object definition.</FONT>
<BR><FONT SIZE=2>Error: Could not add object property in file</FONT>
<BR><FONT SIZE=2>'/usr/local/nagios/etc/hosts.cfg' on line 30.</FONT>
</P>
<P><FONT SIZE=2>Not including the field at all results in Nagios never flagging the</FONT>
<BR><FONT SIZE=2>connection as good which leaves the hosts perpetually grey (unchecked).</FONT>
<BR><FONT SIZE=2>What's the best workaround for this with Nagios? I'd like the hosts to show</FONT>
<BR><FONT SIZE=2>up as good (green). :)</FONT>
</P>
<P><FONT SIZE=2>Thanks,</FONT>
