Nagios Support Forum

Hi you all.

Please, I need support/guidance to solve the following:

I've successfully installed nagios-4.5.12 supported by the guidance below:
https://support.nagios.com/kb/article/n ... tml#Debian

When trying to install the plugins (nagios-plugins-release-2.4.11) following step-by-step commands, I get:

1- Step "./configure" (many) warnings like this:
../gl/gl_openssl.h:105:3: warning: ‘SHA1_Final’ is deprecated: Since OpenSSL 3.0 [-Wdeprecated-declarations]

2- Step "make", the msg error below:
/usr/bin/ld: libnpcommon.a(sslutils.o): in function `np_net_ssl_init_with_hostname_version_and_cert':
/home/msadu/Downloads/nagios-plugins-release-2.4.11/plugins/sslutils.c:190: undefined reference to `SSL_get1_peer_certificate'
/usr/bin/ld: libnpcommon.a(sslutils.o): in function `np_net_ssl_check_cert_real':
/home/msadu/Downloads/nagios-plugins-release-2.4.11/plugins/sslutils.c:264: undefined reference to `SSL_get1_peer_certificate'
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile check_http] Erro 1

Not run the step "make install" and so no plugin is installed.

Any recommendation on how to solve?
Thanks in advance.

Hi,

Have you installed all dependencies?
Best regards

Hi MaterazziSan,

First off all, thanks for your reply.

Yes, I did it before Nagios installation as required by the guideline.

Hi @m_sadu,

On what version of Debian are you installing this? The documentation has not yet been updated for Debian 12 or 13 and there might be some issues with packages.

Thanks,

Hi Emmet,
I'm using MX-Linux (Debian flavor).

As I was suspect that problem was related to openssl cipher when running the plugins compilation, I was able to workaround the issue, removing openssl 3 and installing openssl1.1.1w.
The plugins installation worked and the nagios is running fine.

Thanks all for all reply.
