check_http invalid option ssl is not available

[Hengendro]

Hi,

I configured Nagios 4.1.1 in Centos and the check_http plugin to monitor some websites but i have the same problem some people, this problem is that SSL is not available when i tried to check a https website, i recompile the plugins with the ./configure --with-openssl=/usr/bin/openssl option but still getting same error. Please help me.

This are my configurations:

1-

Code: Select all

Package 1:openssl-devel-1.0.1e-42.el7.9.x86_64 already installed and latest version, Nothing to do 

2- Monitor Plugins Folder

Code: Select all

 [root@linux monitoring-plugins-2.1.1]# ./configure --with-openssl=/usr/bin/openssl 

3- Same Error....

Code: Select all

[root@linux monitoring-plugins-2.1.1]# /usr/local/nagios/libexec/check_http -H digid.nl -C 30

After you run the ./configure --with-openssl please run the following.

Code: Select all

make
make install

That should work, let us know the result.

[Hengendro]

Sorry, yes, i put make and make install after ./configure --with-openssl but getting same error....

[rkennedy]

Hmm, do you have the regular openssl installed as well?
yum install openssl

[Hengendro]

Yes i have

Code: Select all

[root@linux monitoring-plugins-2.1.1]# yum install openssl

I attempted to recreate this issue and it seems to be working fine on my end. Are you behind any kind of proxy that would filter port :443? Can you please post the output that after running ./configure --with-openssl? It will be similar to what's below.

Code: Select all

rkennedy, this is the command output:

Code: Select all

 --with-apt-get-command:
              --with-ping6-command: /usr/sbin/ping6 -n -U -w %d -c %d %s
               --with-ping-command: /usr/bin/ping -n -U -w %d -c %d %s
                       --with-ipv6: yes
                      --with-mysql: no
                    --with-openssl: yes
                     --with-gnutls: no
               --enable-extra-opts: yes
                       --with-perl: /usr/bin/perl
             --enable-perl-modules: no
                     --with-cgiurl: /nagios/cgi-bin
               --with-trusted-path: /usr/local/sbin:/usr/local/bin:/sbin:/bin:/u       sr/sbin:/usr/bin
                   --enable-libtap: no

And i'm not behind of proxy.

For fun, can you do this (assuming you're on a fairly generic RHEL/CentOS box) and post the results?

Code: Select all

rpm -qa | grep -i ssl | sort

Thanks Eric.
