Nagios Support Forum

What is the secret to logging in to the Nagios web interface?
I am new to Nagios, and to Linux as well (a recent convert from AIX).
We are running RHEL 6.5.
I installed and configured Nagios using the Fedora quickstart (http://nagios.sourceforge.net/docs/3_0/ ... edora.html)
I set the nagiosadmin userid/passwd using htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
And I accessed the web interface signon screen with http://pablnx98/nagios/
But every time I enter my userid (nagiosadmin) and password (as set with the htpasswd command, above), it just brings me right back to the same sign on screen.
I've tried changing the password with the htpasswd command, but it doesn't make any difference.
Can you help me?
Thanks.
Jim

Is anything showing up in your apache error log? Is SELinux running? If SELinux is on, you should try turning it off via /etc/sysconfig/selinux - change 'enforcing' to 'disabled' and restart your Fedora box.

Thank you for the reply.
No, we have selinux disabled:

[root@pablnx98 ~]# sestatus
SELinux status: disabled

And below is the apache log (nothing for today, when I attempted to sign into the Nagios web interface):

[root@pablnx98 ~]# tail /var/log/httpd/error_log

Please post the output of this command:

And post the output of this command:

It looks like your htpasswd file is restricted to root only at the moment.
Now try logging in. Nice find ssax!

Excellent!
That did it.
Thank you very much!

Awesome! I'll be closing this thread now, but feel free to open another if you need anything in the future!
