Actually yes! I do see the problem we are having:

Code: Select all

ERROR: cannot verify 127.0.0.1’s certificate, issued by â€/C=US/O=GeoTrust, Inc./CN=GeoTrust SSL CA”:
  Unable to locally verify the issuer’s authority.
    ERROR: certificate common name â€*.snapon.com” doesn't match requested host name â€127.0.0.1”.
To connect to 127.0.0.1 insecurely, use ‘--no-check-certificate’.
This section is the problem - we are using 127.0.0.1 as the hostname which obviously isn't the proper hostname for your certificate. We can try using:

Code: Select all

/usr/local/bin/wkhtmltopdf --no-outline -O "Portrait" --footer-spacing 3 --margin-bottom 14mm --footer-font-size 9 --no-check-certificate --footer-left "Network Analyzer Report" --footer-right "Page [page] of [toPage]" "http://127.0.0.1/nagiosna/index.php/sources/reports/1?download=1&token=<apikey>&q[rid]=1&q[sid]=2" "/tmp/page.pdf"
Then the actual fix for you will be one of two things... find a way for the NNA server to be able to contact itself without being redirected to https or possibly add the above "--no-check-certificate" to the function in the actual NNA code.

Got an error using the --no-check-certificate option, in that it doesn't appear to be an option:

Code: Select all

[root@lisl-ngna-01-pv tmp]# /usr/local/bin/wkhtmltopdf --no-outline -O "Portrait" --footer-spacing 3 --margin-bottom 14mm --footer-font-size 9 --no-check-certificate --footer-left "Network Analyzer Report" --footer-right "Page [page] of [toPage]" "http://127.0.0.1/nagiosna/index.php/sources/reports/55download=1&token=c35dfd74f0b152179aaf212a018642fc1c3f58a3&q[rid]=1&q[sid]=2" "/tmp/page.pdf"
Unknown long argument --no-check-certificate

Name:
  wkhtmltopdf 0.12.2.1 (with patched qt)

Synopsis:
  wkhtmltopdf [GLOBAL OPTION]... [OBJECT]... <output file>
  
Document objects:
  wkhtmltopdf is able to put several objects into the output file, an object is
  either a single webpage, a cover webpage or a table of content.  The objects
  are put into the output document in the order they are specified on the
  command line, options can be specified on a per object basis or in the global
  options area. Options from the Global Options section can only be placed in
  the global options area

  A page objects puts the content of a singe webpage into the output document.

  (page)? <input url/file name> [PAGE OPTION]...
  Options for the page object can be placed in the global options and the page
  options areas. The applicable options can be found in the Page Options and 
  Headers And Footer Options sections.

  A cover objects puts the content of a singe webpage into the output document,
  the page does not appear in the table of content, and does not have headers
  and footers.

  cover <input url/file name> [PAGE OPTION]...
  All options that can be specified for a page object can also be specified for
  a cover.

  A table of content object inserts a table of content into the output document.

  toc [TOC OPTION]...
  All options that can be specified for a page object can also be specified for
  a toc, further more the options from the TOC Options section can also be
  applied. The table of content is generated via XSLT which means that it can be
  styled to look however you want it to look. To get an aide of how to do this
  you can dump the default xslt document by supplying the
  --dump-default-toc-xsl, and the outline it works on by supplying
  --dump-outline, see the Outline Options section.

Hmm it may be the browser option which is why it's showing up after the SSL certificate. Is it possible to allow non-SSL connections from localhost only?

I'd be willing to try that, how would that be set up?

Before we even go down this path and dig into this, can you temporarily disable SSL and run a report to make sure it actually works? This way we will know for sure that we need to work on the SSL issue.

I can try that, what's the best way to go about that? Just want to make sure I edit all the right conf files go revert back to http.

Did you follow the guide at http://assets.nagios.com/downloads/nagi ... alyzer.pdf or did you set it up a different way?

If you type in http://YOURNAGIOSNASERVER does it redirect you to https://YOURNAGIONASERVER automatically?

If yes to the question above, it's either a RewriteRule in /etc/httpd/conf/httpd.conf or in /etc/httpd/conf.d/nagiosna.conf, you would need to find it and comment it out.
- Make sure that you comment out SSLRequireSSL with a # in /etc/httpd/conf.d/nagiosna.conf if it isn't already.

If no to the question above, try it from the http:// one.

One caveat would be that you may need to open port 80 on the local machine or on any firewalls in between if it's locked down.

Got it, found the RewriteRule, forgot it was in httpd.conf. Bad news, I enabled http and PDFs still don't work, same issue even without SSL

Could you post your httpd.conf and the nagiosna.conf config files so we can look at them?
