check_yum – YUM output signature is larger than current known format

If you are using /check_yum you might face the following error…

YUM output signature is larger than current known format, please make sure you have upgraded to the latest version of this plugin. If the problem persists, please contact the author for a fix

nano /etc/nagios/nrpe.cfg

set the correct command to check_yum

command[check_yum]=/usr/lib64/nagios/plugins/check_yum --all-updates

and then restart nrpe

/bin/systemctl restart nrpe.service

Enter passphrase for key id_rsa.pub

So!,

I was trying to SSH a host…
Somehow it was requesting id_rsa.pub……… and asking for an password!

This is how I solved it…

ssh -v -i path/to/id_rsa [email protected]
