A new SCAM is up!
Premature end of script headers: in.cgi
Apache/2.2.15 (Unix) DAV/2
Apache 2.2 not reading the .htaccess?
Try to edit the .conf for the domain and use AllowOverride All.
Save and restart Apache.
ERROR 1214 (HY000) at line 323: The used table type doesn’t support FULLTEXT indexes
Upgrade to 5.6 and use InnoDB Full-Text Search
configuration error: couldn’t perform authentication. AuthType not set!:
On Apache < 2.4 we need to use “Allow from all“
This was tested on a CentOS 7.
This might have TWO possible causes
Some important files/directories
nrpe.cfg – /etc/nagios/nrpe.cfg
nagios/nrpe plugins folder – /usr/lib64/nagios/plugins/
logs – /var/log/messages
My nrpe.cfg, in a CentOS 7, is located at /etc/nagios/nrpe.cfg
In a default nrpe installation log is disabled!
You might want to enable it for better debug of the issues… Go to and enable it.
Yah!, the default installation will came also with debug disabled.
We want it enabled to see more information while we try to use service nrpe status for example.
Server address… it might confuse you!
Server address ISN’T the NAGIOS’s ip address. It’s the actual external IP address of the current machine! allowed_hosts it’s actually it!
netstat -an |grep 5666
If you don’t see any result… this probably means that nrpe is down!
See the ‘section’ Add NRPE to service bellow.
sudo firewall-cmd --permanent --zone=public --add-port=5666/tcp firewall-cmd --reload
sudo systemctl enable nrpe.service sudo systemctl start nrpe.service
