Jonathan,
The client installed on the host doesn't matter if both of them have support to
nrpe. They will have a configuration file where you'll define the commands to
run over check_nrpe.
NSClient++ uses NSC.ini
OpMonAgent uses opmonagent.ini
But to make it easy, the OpMonAgent has a command to restart services built-in
his configuration file.
So, if you have the OpMonAgent running on host, you just need run the following
command from your nagios server:
/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a "spooler" start
But, if you are using NSClient++ you need define a command into the
configuration file first, then you'll use this command in the check_nrpe.

Subject: RE: [Nagios-users] Help - I am unable to get the NSClient++ to restart
services
I feel like I am back at square one. It seems like a simple task to get Nagios
to restart a service. I have NRPE now running on the server under xinedt, and
switched the client back to NSClient++ from OpMon Agent. Both support NRPE. I
am not sure if I am supposed to get a service restarted with a NRPE_Check
command like:
/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a "spooler" start
Or am is supposed to create scripts on the host that will restart a service
like a .bat file with a “net start spooler” command and than get an
event_handler set up to call that script. It seems there are different ways to
do it and I am being pulled both directions. I am new to Nagios as well as
Linux and have been able to scrap my way thus far while learning a lot about
both, but am about ready to call it quits. I was pointed to the NakedNuns
website to the section on CheckExternalScripts, but honestly could not make
much sense of it.

Jonathan,
make sure that you have the xinetd installed and check if there is the
following directory:
[EMAIL PROTECTED] ~]# ls /etc/xinetd.d/
chargen-dgram daytime-dgram discard-dgram echo-dgram eklogin gssftp krb5-telnet
ktalk rsync time-dgram
chargen-stream daytime-stream discard-stream echo-stream ekrb5-telnet klogin
kshell nrpe tcpmux-server time-stream
if you don't have that, try to install by apt-get!
and then, run the command again
Make install-xinetd
or you can install just writing a file like this:
[EMAIL PROTECTED] ~]# cat /etc/xinetd.d/nrpe
service nrpe
{
flags = REUSE
socket_type = stream
wait = no
only_from = 127.0.0.1 (PUT YOURS NARIOS SERVER'S IPS HERE)
user = nagios (PUT THE NAGIOS USER HERE)
server = /usr/local/nagios/libexec/nrpe (THE NRPE SERVER)
server_args = -c /usr/local/nagios/libexec/nrpe.cfg --inetd (THE NRPE CONFIG
FILE)
log_on_failure += USERID
disable = no
}
and then restart xinetd!

I was able to compile that without ssl and was able to install the pugin’s
using the following
Make install-plugin
Make install-daemon
Make install-daemon-config
Those worked finer however the next step says:
Install the NRPE daemon as a service under xinetd
Make install-xinetd
I run that command and get:
[EMAIL PROTECTED]:- /downloads/nrpe-2.8# cannot create regular file
‘/ect/xinetd.d/nrpe’ No such file or directory
make: *** [install-xinetd] Error 1
Any thoughts??
Thanks,
Jon

Hi Jonathan!
try to use the option --disable-ssl when you run ./configure

I am having a little trouble installing the NRPE 2.8 plug in Ubuntu. I am able
to extract the source code tarball and than I am having issues after that. Per
the instructions I am trying to compile the NRPE add-on by running
./configure
make all
After I type ./configure I get a message at the end of the compile job saying
“configuration error: Cannot find ssl libraries. Than if I try to go further by
installing the plugins by typing make all or the individual make
install-pluggin I get an error saying ** No rule to make target ‘all’. Stop.

I found the NRPE add-on (not plug-in) so I will download and install that. I’ll
let you know if I run into anything. You have been more than helpful.

check_nrpe is part of the package nrpe, if you use ubuntu, I believe that only
an "apt-get install nrpe" solve your problem.

OK.. I do not have check_nrpe so apparently I need to download that plug-in on
by Ubuntu box.
