OK, I went back over the prereqs and noticed some level differences so I updated all to the levels that are listed in your earlier post. I've gotten a much better output but I'm now getting the below error on the make.

Code: Select all

Stop.

2 things:

1) PLEASE PLEASE... is this NRPE or Plugins? Did NRPE compile OK? Without NRPE you are absolutely wasting your time. Please do not reply to this thread without including this information.

2) what does line 2144 of Makefile look like. Makefiles are specific to compilation occurrences and yours certainly won't look like mine.

[djjosephk]

I'm assuming this is NRPE. I just grabbed a zip file from the github link you sent earlier. I've unzipped it, ran ./tools/setup, /configure --prefix=/usr/local/nagios --with-cgiurl=/nagios/cgi-bin
and make.
https://github.com/NagiosEnterprises/nrpe


I'm looking at the Makefile but there doesn't seem to be that many lines. I must be doing something wrong.

Code: Select all

# cat Makefile|wc -l
    1885

[jdalrymple]

Sorry if I'm stating the obvious and you already know this, but I just want to make sure you're where you need to be.

Nagios Plugins is a collection of commonly used plugins to gather data about the system. Things like disk usage, cpu usage, whether services are running, etc. These only gather data, they do nothing else. They have no method of transmitting that data to Nagios - that's what NRPE is for.

NRPE - Nagios Remote Plugin Executor - this is an absolute must-have. This is the "agent" that communicates from you AIX box to Nagios. This piece of software can run any arbitrary code (such as plugins) to get data and pass it back to Nagios.

Going back to your issue:

Code: Select all

Target "all-am" is up to date.
Making all in tests
Target "all" is up to date.
Target "all" is up to date.
Making all in plugins

That makes it sound like you're working on plugins not nrpe. If you are indeed for sure in the nrpe build tree, maybe it's a good time to just scratch the whole thing and start fresh?

[djjosephk]

As suggested I started from scratch. I grabbed a new zip file from the Github https://github.com/NagiosEnterprises/nrpe and unpacked it. Ran a compile

Code: Select all

 ./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib

*** Configuration summary for nrpe 2.15 09-06-2013 ***:

 General Options:

 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.

and a make.

Code: Select all

 # make all
        cd ./src/; make ; cd ..
Target "all" is up to date.

*** Compile finished ***

At that point I copied the nrpe binary from src to /usr/local/nagios/bin/ and the check_nrpe to /usr/local/nagios/libexec/

Code: Select all

 /usr/local/nagios/bin/nrpe

and started it up as the nagios user with

Code: Select all

$ /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -n -d

but I'm still getting the "CHECK_NRPE: Error - Could not complete SSL handshake." error.

I've verified that the IP of the nagios server is in the nrpe.cfg allowed_hosts stanza on the client.


Thoughts, observations, admonishments?

[jdalrymple]

Let's try this instead:

Code: Select all

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d -s

Explanation:

Code: Select all

Usage: nrpe [-n] -c <config_file> [-4|-6] <mode>

Options:
 -n            = Do not use SSL
 <config_file> = Name of config file to use
 -4            = use ipv4 only
 -6            = use ipv6 only
 <mode>        = One of the following operating modes:
   -i          =    Run as a service under inetd or xinetd
   -d          =    Run as a standalone daemon
   -d -s       =    Run as a subsystem under AIX

[djjosephk]

Even if it list it as and option it doesn't seem to like it.

Code: Select all

# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg  -d -s
/usr/local/nagios/bin/nrpe: illegal option -- s

[djjosephk]

I've been able to get it up with just the -d option and now I get.

Code: Select all

NRPE: Unable to read output

[jdalrymple]

Code: Select all

NRPE: Unable to read output

So is this from the nagios server? Do you get the same thing if you run

Code: Select all

check_nrpe -H 127.0.0.1

check_nrpe should have landed in that same src directory after compiling.

This is a screen shot from the Nagios XI web console. I also want to reiterate that this is when I start up the nrpe daemon with only the -d option.

Code: Select all

# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg  -d

If I try to use the -d and -s option it errors out and will not run.

Code: Select all

# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg  -d -s
/usr/local/nagios/bin/nrpe: illegal option -- s

I copied the check_nrpe to /usr/local/nagios/libexec/ after the compile. If I execute the requested command on the AIX server I'm attempting to configure I get.qh

Code: Select all

$ /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.15

If I try it on the assigned IP I get

Code: Select all

$ /usr/local/nagios/libexec/check_nrpe -H 111.222.333.444
CHECK_NRPE: Error - Could not complete SSL handshake.
