check_http perl script not working with SSL ?

It's a 64b CentOS 6.5.

This is my output:

I opened this raw file in my windows host:
https://raw.githubusercontent.com/nagio ... eck_http.c

and copy/pasted it directly into my CentOS host via Putty.

[tmcdonald]

Yea, that's why. Our plugins have some common shared functions that are included in header files. By just downloading the check_http.c you are not including any of the necessary headers. I would suggest compiling the whole plugins project and hand-picking the check_http and any other plugins you may need.

[reinaldo.gomes]

Is this the whole plugins package? Does it differ from GitHub's files?

[tmcdonald]

Assuming they had their coffee both of those links should be for the 2.0.3 release.

[reinaldo.gomes]

So, I've downloaded nagios-plugins-2.0.3 to my /tmp/ folder, unpacked, then I did (from inside the unpacked folder):

./configure
make all
make install

But how do I know if my plugins were really updated?

Also, when I do: "yum install nagios-plugins-all"
I get a list of 'version 1.4.16-10.el6' plugins.
Does it mean my repository is outdated, since the latest package's version is 2.0.3?

[abrist]

But how do I know if my plugins were really updated?

Well, unless you specified an install folder in configure, they would have installed to the default path of: /usr/local/nagios/libexec
You can check the version by running "-V" with any of the plugins:

Code: Select all

/usr/local/nagios/libexec/check_http -V

Does it mean my repository is outdated, since the latest package's version is 2.0.3?

Yes, the cent/rhel repos are out of date.

[reinaldo.gomes]

You can check the version by running "-V" with any of the plugins:

Indeed. I can see it's updated (2.0.3). But the '-t: unknown' option doesn't seem to work. Maybe because I got the plugins from nagios-plugins.org, not GitHub.

[tmcdonald]

Does it give any errors for the -t option or does it just not work as expected? Please post the output of running the command from the CLI.

[reinaldo.gomes]

Code: Select all

[root@localhost libexec]# ./check_http localhost -t :unknown
check_http: Timeout interval must be a positive integer - :unknown

 check_http -H <vhost> | -I <IP-address> [-u <uri>] [-p <port>]

       [-A string] [-k string] [-S <version>] [--sni] [-C <warn_age>[,<crit_age>]]
       [-T <content-type>] [-j method]

[abrist]

You need to download the "timeout_state" branch from github as this code is not yet into trunk. Follow the steps below:

Code: Select all

cd /tmp
wget https://github.com/nagios-plugins/nagios-plugins/archive/timeout_state.zip
unzip timeout_state
cd nagios-plugins-timeout_state
./tools/setup
./configure
make

Now test the plugin:

Code: Select all

./check_http localhost -t :unknown

If it works, install the plugins:

Code: Select all

make install
