Are you using IPV4 on your machine? Can you post the output of ifconfig?

Posted: **Tue Dec 08, 2015 2:23 pm**

if ifconfig isn't installed, try

ip /a

thanks

Hello Gents,

for somehow i've stopped the firewall.d service and the nagios web worked very well.

now how to add the following
1- add the nagios to the firewall.
2- secure my server and build a decent firewall allow me to access using ssh and http & https
