Error when I try to check the * .com domain
by Sivich, April 30, 2018

I have the same problem I'm trying to test the domain test, but get an error: ./check_domain.sh -d vk.com UNKNOWN - WHOIS exited with error 1.


Error when running whois
by kaioccarvalho, April 30, 2017

When I try to run ./check_domain.php -d the message "Error running whois" appears. It seems occur for all domains in godaddy.com. Could you help me?


update for ru and xn--p1ai domains
by Kolos, March 31, 2017

now date format for ".ru" and cyrillic ".xn--p1ai" domains is ISO so you should change this string /paid-till:/ && $NF ~ DATE_YYYY_MM_DD_DOT {split($2, a, "."); printf("%s-%s-%s", a[1], a[2], a[3]); exit} to this one /paid-till:/ && DATE_ISO_FULL { get_iso_date($0, ":", 2) }


Like this but need .co.nz?
by LostBoy, May 31, 2015

This worked a treat but it doesn't seem to work for our .co.nz domains (Which is an issue since I live here with most of my clients). ./check_domain -d stuff.co.nz UNKNOWN - Unable to figure out expiration date for stuff.co.nz Domain. Any ideas on how I can update this script to work for .co.nz domains? I tried a bunch of .co.nz's and none of them seem to work. Cheers


Thanks
by wasserja, March 31, 2015

Thanks for this plugin. I started using it today, but found that you can get blocked by network solutions very quickly. Make sure you only check your domains infrequently so as to not violate their policy.


Godaddy did it again.
by hprins, October 31, 2014

As of last month, when doing any lookups from godaddy it seems that they no longer provide expiration dates in their whois report.


md domain
by jwehnerhf, October 31, 2013

Does anyone have any idea on how to get .md domains to show up?


Very Easy & Effective Tool
by nishith, October 31, 2013

Worked perfectly. Just download it & make following changes in Nagios configuration. In /usr/local/nagios/etc/objects/commands.cfg define command { command_name check_abc.com command_line $USER1$/check_domain -d $ARG1$ -w $ARG2$ -c $ARG3$ } #################################### In /usr/local/nagios/etc/objects/localhost.cfg define service{ use generic-service ; Inherit values from a template host_name localhost service_description Domain Expiry of abc.com check_command check_abc.com!abc.com!30!10 Here, 30 = Warning of 30 days remaining 10 = Critical message of 10 days remaining Nishith N.Vyas


Godaddy messed this up
by RFD, August 31, 2013

I have been using the script for about 4 years without issues. Just a few hours ago, I started getting critical alerts saying that my domains had expired, but the dates were in the future. It appears GoDaddy changed the information that they were returning through the whois database today, and the grep command on line 60 started returning two lines of data which messed up the script. I was able to simply add two spaces to the grep portion of line 60. Which then made the grep command only return the proper line. grep " Expiration Date:"


CentOS 6.3 change to who is
by Kirk, February 28, 2013

To get this to work on CentOS I had to modify line 60 to this: expiration=`whois communitect.com |grep "Expires"| awk -F":" '{print $2}'|cut -f 1` The who is "Expires on" string varied from what the program is looking for.


Edit to work with multiple TLD
by gary.turner, October 31, 2012

Edit to line 60 so it works with uk.com, .ie and most others too expiration=`whois $domain |egrep "renewal:|Expiration Date:|Renewal date:|Expiry date:" | head -n 1 | sed 's/^[^:]*://' | awk '{print $1}'`


naum's .ca addon fix
by elyrith, October 31, 2012

Excellent plugin. The array order in naum's addon for .ca domains is wrong, though: *.ca) expiration=$(echo "$out" | awk '/Expiry date:/{split($3, a, "/"); printf("%s/%s/%sn", a[2], a[3], a[1])}') ;; (Also, this is version 1.01. I got 1.2.1 from http://git.pld-linux.org/gitweb.cgi/?p=packages/nagios-plugin-check_domain.git;a=summary)


.ca works
by naum, September 30, 2011

*.ca) expiration=$(echo "$out" | awk '/Expiry date:/{split($3, a, "/"); printf("%s/%s/%sn", a[3], a[2], a[1])}') ;; Add this into script and .ca will work fine.


Works Great
by vihag, August 31, 2011

It works great, but it doesn't seem to work with .ca domains, even though a regular whois lookup will. Does anyone know how I can get this to monitor .ca domains?


integra wrong way round
by rooneybuk, July 31, 2011

excellent script, im just a little confused it seems to alert warning or critical if the value is high instead of lower>


Great idea to build on
by svindler, May 31, 2011

This line allows for even more domains: expiration=`whois $domain |egrep -i "((Expir)|(Renew)).*20[0-9][0-9]"|sed -e 's/s/n/g'|grep "20[0-9][0-9]"|tail -1`


FYI
by Leo Tao, April 30, 2011

A little changes I did to fit for more whois result: expiration=`whois $domain |grep -i "Expir.*20[0-9][0-9]"|sed -e 's/s/n/g'|grep "20[0-9][0-9]"` > # date format dd-mm-yyyy (UK format) transmition > ukdate=`echo $expiration | grep "[0-3][0-9]-[0-1][0-9]-20[0-9][0-9]$"` > [ -n "$ukdate" ] && expiration=`echo $ukdate|awk -F"-" '{print $3"-"$2"-"$1}'`


patch for nominet domains
by rob.turner, March 31, 2011

Works well, great thing to check and if you change line 60 to: expiration=`whois $domain |egrep "Expiration Date:|Renewal date:"| awk '{print $3}'` it works for UK domains too.
