Getting 403 errors at login

Post by corrinmana »

So installed Nagios using the Fedora quickstart guide. Preflight check OK. But when I try to log in I get a 403 permission denied error. I looked at answers to the problem other people posted, but the answers all revolved around adding an index.html file to the Apache/httpd folder and I already have one in there. I only get the message when I have the correct username/password, getting it wrong gives me the prompt 'authentication failed, would you like to try again y/n?'

I'm running the webserver on an EC2 instance (T1 micro) and using the Amazon-linux that comes with it. My understanding is that Amazon-linux is most like CentOS.

Let's check a few things.

Code: Select all

grep -i 'nag' /etc/group
ls -lv /usr/local/nagios/sbin
ls -lv /usr/local/nagios/share
tail -n 20 /usr/local/nagios/var/nagios.log
tail -n 20 /var/log/messages
Nagios-Plugins maintainer exclusively, unless you have other C language bugs with open-source nagios projects, then I am happy to help! Please pm or use other communication to alert me to issues as I no longer track the forum.

Should note that adding Apche to the nagios group and restarting did not solve the issue.
