Re: [hobbit] how to get dnsreg to work .. ?

[Ralph Mitchell <ralphmitchell (at) gmail.com>]

I see a couple of things that could be wrong.  Possibly you should be doing
"DOMAIN=$2" in the loop??  $1 is the ip address, $2 is the fully-qualified
hostname.  It seemed to work just fine when I replaced the bbhostgrep line
with

     echo "yahoo.com" | while read L

Definitely you should be converting the dots in $DOMAIN to commas.  See the
second paragraph under "XYMON MESSAGE SYNTAX" in the bb.1 manpage.  This
would do it:

   DOM=`echo $DOMAIN | sed -e 's/\./,/g'`
   echo $BB $BBDISP "status+12h $DOM.dnsreg $COLOR `date`

You can test your script using bbcmd:

   server/bin/bbcmd  server/ext/dnsreg

That kicks off the script with the same environment that Xymon gives it.
 You probably want to put a  'set -x' in at the top, to see everything
that's going on.  I generally put an "echo" in front of the $BB line when
testing, to minimize the amount of bogus reports going to the server.
