Nagios Support Forum

Dera Team,

I am installing nagiosxi at one of the client place who has a SUSE system in their infrastructure.When i am trying to install NRPE agent on SUSE linux its throwing error "NRPE is not supported on SUSE linux"
Please help us in installing NRPE on SUSE linux.Our client is using SLES11,SLES12 all service pack.

You will likely have to install with the non pre-packaged version. Instructions are here

Dear Team,

The Link given by you for nrpe on suse linux only support SLES11 SP-3 and upward version.In our envirement we have SLES 11 SP-2.

How can we install NRPE on SLES 12-SP2 version.

Use the instructions for SP3. There may be other packages or additional steps that need to be taken for older versions of SUSE which should result in errors or warnings when trying to do the install.

We have done all the configuration as per the document. Also referred one more doc:
https://assets.nagios.com/downloads/nag ... e/NRPE.pdf

After doing all configuration, the port 5666 is not listening in suse server.

Did you start the service?

Is the process running?

No, there is no nrpe process. please find below output:

Oh you installed it under xinetd, can you share

This is the original file:
susemgr:~ # cat /etc/xinetd.d/nrpe.bak
# default: off
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
disable = yes
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
only_from = 152.63.2.94
log_on_success =
}


But as it was not working, so we have copied a nrpe file from some different working environment. posting here:

susemgr:~ # cat /etc/xinetd.d/nrpe
# default: off
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 152.63.2.94
}

so do either work?
can you see the port open here? If not after restarting xinetd can you run the following and post the contents
