I have a Nagios Core machine sending NRDP obsessions to NagiosXI with a valid (as far as I can tell) token. There is nothing showing up in Unconfigured Hosts
I see bits flying to...

And on the Nagios Core machine:

Not sure where to go next

Also, I tried this:
https://support.nagios.com/forum/viewto ... 75#p256356
and upgraded to 5.7.3, yum update -y and rebooted

Here's the answer
https://support.nagios.com/forum/viewto ... 16&t=48398

added "Require all granted" to /etc/httpd/conf.d/nrdp.conf and restarted httpd. I assume that's a valid / supported adjustment?

Yes, that's valid.

Here's what I have for nrdp.conf:

Code: Select all

Alias /nrdp "/usr/local/nrdp/server"

<Directory "/usr/local/nrdp">
#  SSLRequireSSL
   Options None
   AllowOverride None
   <IfVersion >= 2.3>
      <RequireAll>
         Require all granted
#        Require host 127.0.0.1
#        AuthName "NRDP"
#        AuthType Basic
#        AuthUserFile /usr/local/nrdp/htpasswd.users
#        Require valid-user
      </RequireAll>
   </IfVersion>
   <IfVersion < 2.3>
      Order allow,deny
      Allow from all
#     Order deny,allow
#     Deny from all
#     Allow from 127.0.0.1
#     AuthName "NRDP"
#     AuthType Basic
#     AuthUserFile /usr/local/nrdp/htpasswd.users
#     Require valid-user
   </IfVersion>
   Require all granted
</Directory>

You may want to double-check your nagios.conf:

Code: Select all

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
#  SSLRequireSSL
   Options ExecCGI
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
   AuthName "Nagios Core"
   AuthType Basic
   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
   Require valid-user
   Require all denied
</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">
#  SSLRequireSSL
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
   AuthName "Nagios Core"
   AuthType Basic
   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
   Require valid-user
   Require all denied
</Directory>

And your nagiosxi.conf:

Code: Select all

<Directory "/usr/local/nagiosxi/html">
#  SSLRequireSSL
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
#   AuthName "Nagios XI"
#   AuthType Basic
#   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
#   Require valid-user
   Require all granted
</Directory>

Alias /nagiosxi "/usr/local/nagiosxi/html"

# Special configuration to allow .htaccess in custom includes
<Directory "/usr/local/nagiosxi/html/includes/components/custom-includes">
    AllowOverride All
    Options None
   Require all granted
</Directory>
