Hi,

I have an issue with one of my checks. Basically I'm trying to monitor a HTTPS vhost. Initial setup was fine, for both HTTP and HTTPS.
The issue occur when I deployed the site live. Because the client wishes to force HTTPS, I'm getting the following:

The response from HTTPS vhost:

Code: Select all

root@hera:/usr/local/nagios/libexec# ./check_http -I 10.123.45.67 -H domain.com -S
HTTP WARNING: HTTP/1.1 403 Forbidden - 7472 bytes in 0.101 second response time |time=0.100901s;;;0.000000 size=7472B;;;0

The response from HTTP vhost:

Code: Select all

root@hera:/usr/local/nagios/libexec# ./check_http -I 10.123.45.67 -H domain.com   
HTTP OK: HTTP/1.1 301 Moved Permanently - 463 bytes in 0.002 second response time |time=0.002416s;;;0.000000 size=463B;;;0

If I put -v I get the page, but the Apache response is still 403.

This are my vhosts on the live server:

Code: Select all

<VirtualHost *:80>
       ServerName domain.com
       ServerAlias www.domain.com

       Redirect permanent / https://www.domain.com/

        ErrorLog ${APACHE_LOG_DIR}/domain-error.log
        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/domain.log combined

</VirtualHost>

The webpage is working fine on the browser. I have test it from my IP and from external IP's to double check.

Thank you.

The 301, makes sense as this is a redirect and the check_http does not follow them. The 403 however is a bit more interesting. Just to verify, going to domain.com works fine with no other URI specified. Also it does not need a subdomain like www.domain.com?

Hi, thank you for the reply.

To confirm, going to domain.com works fine.
It will redirect by default to https://www.domain.com

One more thing that I forgot to mention is that I have forbidden directory traversal in Apache (-Indexes).

Thank you.

What about if you specify index.(php\html\cgi), or whatever the normal landing page is aside from just domain.com with the -u parameter. It seems that with indexing disabled check_http and apache are fighting. Specifically apache saying, that doesn't exist and I wouldn't let you go there anyway, and check_http not redirecting even if apache was trying.

Thank you., That solved my issue

root@hera:/usr/local/nagios/libexec$ ./check_http -I 12.34.56.78 -H -u domain.com -S
HTTP OK: HTTP/1.1 200 OK - 881 bytes in 0.014 second response time |time=0.014401s;;;0.000000 size=881B;;;0

Have a great day! Thanks again.
