I was following the doc http://nagios.sourceforge.net/docs/3...rt-fedora.html to install nagios.But when I tried to install nagios-plugin tool through rpm it went well but when tried to install thru tar ball it stops permanently:
----------------------------------
checking for redhat spopen problem.
------------------------------------
Any Idea?IF I ignore it and run
#service nagios restart
It says Started Successfully
But the Webserver tends to show the warning:

[root@psatest01 ~]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [Sat Dec 08 01:05:10 2007] [warn] The ScriptAlias directive in /etc/httpd/conf.d/nagios.conf at line 1 will probably never match because it overlaps an earlier ScriptAlias.

[root@psatest01 ~]#htmlview http://localhost/nagios
Not working


Plzzz help??

I was having this issue too. I mistakenly uncommented out the following line in /etc/httpd/conf/httpd.conf (it was at the very end of the file)

#Include /etc/httpd/conf.d/nagios.conf

it seems everything in conf.d is already included so uncommenting this line causes the nagios.conf file to be included twice. Once i fixed the mistake and restarted apache things were fine.
