Where to start!?

[trafalgargirl]

I think you are giving me too much credit

Will try and see if I can figure this out but at the moment this is a bit over my head.

[trafalgargirl]

Ok so I am a bit befuddled. Sorry for the possibly very dumb questions.

I am installing the NRPE on the nagios server or the client server?

On the client server I am now getting the following error:

root@ip-/tmp/nrpe-2.15# /usr/local/nagios/libexec/check_nrpe -H nagiosIP
-bash: /usr/local/nagios/libexec/check_nrpe: No such file or directory

On the nagios server
same command
CHECK_NRPE: Socket timeout after 10 seconds.

[trafalgargirl]

I have just checked on both servers and when trying to run useradd for nagios I get - useradd: user 'nagios' already exists

[trafalgargirl]

and new information from the client server - I went back and retraced all my steps...

Go to where i needed to check to see if nope got installed and configured correctly:

root@ip-ipadd:/usr/local/nagios/libexec# ./check_nrpe -H localhost
CHECK_NRPE: Error - Could not complete SSL handshake.

[trafalgargirl]

So I tried to troubleshoot and checked a few thing (that the IP was added properly) and also tried to enable ssl
./configure --enable-ssl-lib=/usr/lib/x86_64-linux-gnu/

but now I am just back to the checking for SSL libraries... configure: error: Cannot find ssl libraries

Sigh.

Any direction on where to go next?

To recompile Nagios Plugins with SSL, you'll need the openssl-devel package.

What is the result if you run a check_nrpe without SSL?

Code: Select all

./check_nrpe -H localhost -n

On the client machine, did you compile NRPE?

[trafalgargirl]

root@nagios:~# ./check_nrpe -H localhost -n
-bash: ./check_nrpe: No such file or directory

On the client side I thought I did but honestly at this point am not sure any more.

[trafalgargirl]

root@nagios:~# apt-get install libssl-dev
Reading package lists... Done

libssl-dev is already the newest version.
The following packages were automatically installed and are no longer required:
libgudev-1.0-0 gir1.2-gudev-1.0 python-twisted-names
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So I assume everything is installed?

[rkennedy]

root@nagios:~# ./check_nrpe -H localhost -n
-bash: ./check_nrpe: No such file or directory

On the client side I thought I did but honestly at this point am not sure any more.

Try with the full command, /usr/local/nagios/libexec/check_nrpe -H localhost -n

Is openssl-dev installed on the nagios machine, and on the NRPE machine?
