[Xymon] dnsreg script question

[Dugan, Darin D [EIT]]

The line in your last message is incomplete. The whole command is:

$XYMON $XYMSRV "status+90000 $DOMAIN.dnsreg $COLOR `date`

Domain $DOMAIN expires on $EXPIRESTRING
"

Which translates to something like:

/home/xymon/server/bin/xymon 1.2.3.4 "status+9000 domain.com.dnsreg green Fri Sep 21 11:45:06 CDT 2012

Domain domain.com expires on 30-Nov-2012
"

Which means the 'xymon' program is sending to the xymon server on 1.2.3.4, everything in double quotes. Which happens to be a status message for host domain.com, test dnsreg, green status, then the extra text of the date, blank line, "Domain ....". When the test appears in the web pages the status will be reflected and the extra text will be shown on screen.

Cheers.

Ok let me tweak it around. What does this line do anyhow? I keep seeing that pop up and then the error about command being not found
thanks

Rereading your message, it seems perhaps $XYMON or $XYMDISP are not populated. Are you running this under xymoncmd to set the environment? I run from cron daily with:

/home/xymon/server/bin/xymoncmd --env=/home/xymon/server/etc/xymonserver.cfg /home/xymon/server/ext/dnsreg

A few other differences in my script:

1.       I'm using $XYMSRV instead of $XYMDISP. Hmm...I don't have a $XYMDISP anywhere, maybe $BBDISP wasn't updated to $XYMSRV properly?

2.       Added a "sleep 60" command before "done". Whois seems to get angry with me if I query a bunch of domains in quick succession.

3.       Had to modify the sed commands for EXPIRESTRING:
EXPIRESTRING="`whois $DOMAIN | egrep -i "Expires.*:|Expiration.*:|Renewal.*:" | head -n 1 | cut -d: -f2 | sed -e's/^\s*//' | sed -e's/\s.*//'`"

Cheers.

I installed  'whois' and I am able to do a manual query 'whois domain.com'. but unable to run the script manually to test it.

I'm guessing you don't have 'whois' available or in the path.

I am having an issue trying to get the dnsreg script working. I install it and all and when I go to test it I get this (I took out my domain). Any help would be appreciated.

Thanks


./dnsreg.sh: line 31: status+90000 mydomain.com.dnsreg red Thu Sep 20 17:27:42 EDT 2012

Domain mydomain.com expires on
: command not found



The script looks like this:


#!/bin/sh

# Check DNS registrations in whois and warn when they are about to expire.
#
# NOTE: Requires a "whois" command that knows what servers to query.
#       Requires GNU date.
#       Should run only once a day.

NOW=`date "+%s"`
WARNTIME=`expr $NOW + 864000`        # 10 days
ALARMTIME=`expr $NOW + 432000`       # 5 day

/home/xymon/server/bin/xymongrep dnsreg | while read L
do
      set $L
      DOMAIN=$2

      EXPIRESTRING="`whois $DOMAIN | egrep -i "Expires.*:|Expiration.*:|Renewal.*:" | head -n 1 | cut -d: -f2 | sed -e's/^[     ]*//'`"
      EXPIRES=`date --date="$EXPIRESTRING" "+%s"`

      if test $EXPIRES -le $ALARMTIME
      then
         COLOR=red
      elif test $EXPIRES -le $WARNTIME
      then
         COLOR=yellow
      else
         COLOR=green
      fi

      $XYMON $XYMDISP "status+90000 $DOMAIN.dnsreg $COLOR `date`

Domain $DOMAIN expires on $EXPIRESTRING

done
