1. I have a suggestion for the iptables
   #show all iptables with line numbers
   iptables –list –line-numbers
   #delete INPUT rule number 5
   #that’s the default block all on CentOS minimal installation
   iptables -D INPUT 5
   #add in the iptables rule to accept port 80
   iptables -A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT
   #re-add the REJECT all rule for everything else at the end
   iptables -A INPUT -j REJECT –reject-with icmp-host-prohibited
   #save your iptables
   service iptables save
   #confirm
   iptables –list –line-numbers

2. You can also change the lines for editing the files to make it easy to copy and paste

   vi /etc/selinux/config
   # Search and repalce row: “SELINUX=enforcing”
   # with: “SELINUX=disabled”
   :%s:SELINUX=enforcing:SELINUX=disabled
   #save your file
   :wq

   # Search and replace row: “$USER1$=/usr/lib64/naemon/plugins”
   # with: “$USER1$=/usr/lib64/nagios/plugins”
   vi /etc/naemon/resource.cfg
   :%s:/usr/lib64/nagios/plugin:/usr/lib64/naemon/plugins
   #Save your file
   :wq

   1. Thanks, It took a while for me to see your comment. Sorry about that.

      I will look at you suggestions and incorporate them since they make sense =)

      Regards Johan

3. Johan,

   Thanks for taking the time to read my suggestions. This is probably easier that what I suggested before.

   iptables -I INPUT 4 -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

   -I (inputs to the) INPUT (chain at line 4) -m(match) state –state NEW -m tcp -p(port) –dport (destination port) 80 -j ACCEPT.

   They also fixed /etc/naemon/resource.cfg so you don’t have to do the find replace any more.

   I would suggest setting the iptables and killing SELinux earlier in the instructions so that Naemon doesn’t complain while installing. It’s not the end of the world but it helps.

   1. Yes, this article was written during early days before naemon.org documentation was created and the 0.8 was still under development.

      I will update the official documentation as well.

      Thanks

4. Hi Johan,
   Have you manage to install Naemon on existing Nagios?
   After installation I cant login to webgui.
