Monitoring IPv6 website

[Frank Bulk]

I tested that theory a few months ago, but alas, that's not it, as 301 does
work just fine for www.qwest.com, but not for www.timerwarnercable.com

root at nagios:/usr/lib/nagios/plugins# ./check_http -6 -H www.qwest.com
HTTP OK: HTTP/1.1 301 Moved Permanently - 589 bytes in 0.163 second response
time |time=0.163363s;;;0.000000 size=589B;;;0
root at nagios:/usr/lib/nagios/plugins#
root at nagios:/usr/lib/nagios/plugins# ./check_http -6 -H
www.timewarnercable.com
CRITICAL - Socket timeout after 10 seconds
root at nagios:/usr/lib/nagios/plugins#

We may need a NAGIOS developer who understands the check_http code to chime
in.

Regards,

Frank

I think you may have answered your own question.  

it would seem to me that check_http only considers http response codes
in the 200 range to be successful and valid, whereas a redirect to a
different server isn't thought to be a successful test/connection.   
I'd have to play with some web servers to confirm that notion
