[SOLVED] [NAGIOS] can't find check_nrpe after 'yum install check_nrpe'

di11rod · 06-28-2011, 05:20 PM

I've run 'yum install check_nrpe' which appeared to have completed successfully. If I re-run that command, I get:

Code:

Package nagios-plugins-nrpe-2.12-16.fc14.x86_64 already installed and latest version

But there is no check_nrpe in the /usr/local/nagios/libexec directory. I've tried a which and a whereis and a find and that turns up nothing for 'check_nrpe'.

Here's what's in my libexec directory:

Code:

check_apt
check_breeze
check_by_ssh
check_clamd
check_cluster
check_dhcp
check_dig
check_disk
check_disk_smb
check_dns
check_dummy
check_file_age
check_flexlm
check_ftp

check_ping
check_pop
check_procs
check_real
check_rpc
check_sensors
check_simap
check_smtp
check_spop
check_ssh
check_ssmtp
check_swap
check_tcp
check_time
check_udp
check_ups
check_users
check_wave
negate
urlize
utils.pm
utils.sh

Any ideas on how I can find check_nrpe? Do I need to compile from source?

Thanks in advance for any advice.

run "rpm -ql check_nrpe"

nrpe is *HORRIBLE* though, I would REALLY suggest using a secure mechanism like func or SSH instead of this awful hack.

Thank you for this suggestion. RPM doesn't register check_nrpe as being installed:

Code:

rpm -ql check_nrpe
package check_nrpe is not installed

On the remote machine, I'm running nsclient++ (windows server 2008). On this Fedora server, I'm running Nagios to monitor all the Windows servers. If there is some documentation on replacing nrpe with func, I'd love to see it and consider going in that direction.

As for security, each of these machines are behind a firewall in a data center with no access from the internet. Even the machines on the intranet that can talk to these servers are limited to a few servers (no desktops).

I just ran this command and yum is still telling me that check_nrpe is installed:

Code:

yum install nrpe nagios-common nagios-plugins nagios-plugins-{disk,dns,users,load,procs}

Should I remove nrpe and install with rpm?

duh, sorry... "rpm -ql nagios-plugins-nrpe"

you don't need documentation on how to replace it, nrpe isn't integrated into nagios at all in the first place. If you want I can provide a script I wrote that uses func with an ssh fallback, there is also a check_ssh module that can be literally dropped in instead of check_nrpe, just set up preshared keys and off you go.

but then TBH, I was assuming this was linux to linux...

Chris,

Thanks a LOT! The mystery is solved. Every resource I consulted indicated that check_nrpe would be in usr/local/nagios/libexec. Thanks to the rpm syntax you helped me with, I found that on our Fedora 14 x64 environment, the binary was placed in:

/usr/lib64/nagios/plugins/check_nrpe

I'll edit the title of this post to include '[SOLVED]'.

Thanks again,

Seth
