Error getting NRPE to install on Redhat 8

[HIINNS]

All, I am trying to install a NRPE agent on a Redhat 8 server. I get the following error messages when I run the install :

Please provide direction to resolve problem. Thank you.

Sorry, this is the 1st error encountered -> 139967465985856:error:050C90CA:Diffie-Hellman routines:DH_generate_parameters_ex:non FIPS method:crypto/dh/dh_gen.c:31:

What were the arguments you passed to "./configure"?

What was the output from when you ran "./configure"?

[HIINNS]

./configure --enable-command-args --with-piddir=/var/run/nrpe --libexecdir=/usr/local/nagios/libexec $libssldir $EXTRACFG

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.

What is EXTRACFG[/code] set to? Can you run this command and post the output?

Code: Select all

echo $libssldir $EXTRACFG

Is this running as part of an automated script?

[HIINNS]

echo $libssldir $EXTRACFG. Both were blank. Sorry for not getting back sooner. I was off yesterday.

[dchurch]

Can you try install nrpe from the package repo using the instructions at repo.nagios.com?

Code: Select all

rpm -Uvh https://repo.nagios.com/nagios/8/nagios-repo-8-1.el8.noarch.rpm
yum install nrpe

[HIINNS]

Can't install this way. I have no internet access on any of my servers.

[gsmith]

Hi,

I attached a tarball of nrpe and its dependencies. Can you "sneakernet" it over to
the network your servers are on?

Thanks

[HIINNS]

I was able to download the tar ball, and successfully installed nrpe. The data collection is now working. Thank you all for helping me. Feel free to close out the case.
