This indicates that the configuration options for the 'ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin' and 'Alias /nagios /usr/local/nagios/share' on lines 566 and 583 of your httpd.conf file aren't taking effect. This is probably because there is a file in /etc/httpd/conf.d (possibly 'nagios.conf'?) that is being loaded before apache parses those lines in your httpd.conf file (see line 210 of your httpd.conf file: 'include conf.d/*.conf'). Have a look at the file in /etc/httpd/conf.d and see what ScriptAlias and Alias definitions exist in that file. It might in fact make more sense to put the nagios web configuration in that file rather than in the httpd.conf file... though it's up to you. There should only be one definition for the nagios Alias and ScriptAlias definitions, and they should be as they currently are in your httpd.conf file.<br>

you restarted apache after editing httpd.conf?<br>What is the output of
'apachectl configtest'?<br>What files are in /usr/local/nagios/sbin -- are they
files like 'status.cgi', 'avail.cgi', 'cmd.cgi' etc.? Are they executable by the

Linux or Unix host (sorry, can't remember if you've specified this before)? If
so, which flavour/version?<br>Did you compile nagios on this host, install it
via a package manager, or copy it from another
