unable to install nagios client on ubuntu 16.04.5 LTS

[gornm565]

I am getting an error below when installing the linux-nrpe-agent on Ubuntu. I am attaching the install.log as well - can you help me figure out why it's not installing?

Hello @gornm565,

What instructions did you follow for installing NRPE?

Can you try again running the following commands as root:

Code: Select all

cd /tmp
wget http://assets.nagios.com/downloads/nagiosxi/agents/linux-nrpe-agent.tar.gz
tar xzf linux-nrpe-agent.tar.gz
cd linux-nrpe-agent
./fullinstall

Let me know if that works.

[gornm565]

That's exactly what I did.

[benjaminsmith]

Hi @gornm565,

Ok. Some require packages maybe be missing. Please run the following to install prerequisites:

Code: Select all

sudo apt-get update
sudo apt-get install -y autoconf automake gcc libc6 libmcrypt-dev make libssl-dev wget openssl

Then try running the install script again. If it fails again, what is the output of sestatus?

[gornm565]

Looks like everything is already up-to-date

The program 'sestatus' is currently not installed. You can install it by typing:
apt install policycoreutils

[lmiltchev]

That's exactly what I did.

I am not sure then how to explain this:

cd ./src/; make
make[1]: Entering directory '/home/sysops/linux-nrpe-agent/subcomponents/nrpe/nrpe-3.2.1/src'

If you ran the same commands, you should've had this:

cd ./src/; make
make[1]: Entering directory '/tmp/linux-nrpe-agent/subcomponents/nrpe/nrpe-3.2.1/src'

It seems you didn't run the installer from the /tmp directory.

Run the following commands and show the output in code wraps:

Code: Select all

uname -a
cat /etc/*release
dpkg -l | grep ssl
cat /etc/apt/sources.list

Try installing xinetd manually:

Code: Select all

apt-get install xinetd

and rerun the fullinstall script:

Code: Select all

./fullinstall

Did the install finish successfully or at least went a bit further?

Previously I ran the install from my home directory. I just did it from /tmp but I got the same error:

Code: Select all

*** Configuration summary for nrpe 3.2.1 2017-09-01 ***:

 General Options:

 NRPE port:    5666
 NRPE user:    nagios
 NRPE group:   nagios
 Nagios user:  nagios
 Nagios group: nagios


Review the options above for accuracy.  If they look okay,
type 'make all' to compile the NRPE daemon and client
or type 'make' to get a list of make options.

The problem is with the custom openssl path that you have on your system. This is definitely NOT a "clean" (unmodified) Ubintu 16.04 box... In the log we see:

checking for openssl... /opt/anaconda2018.12/bin/openssl

You may want to try running:

Code: Select all

./configure --with-ssl-lib='/proper/path/to/latest/openssl'
