I am trying to configure VNC on my server. I found this guide which seems very easy: https://rbgeek.wordpress.com/2012/06/26/how-to-install-vnc-server-on-centos-6/
Lastly, I got to iptables configuration:
when I run this command as exactly as guide told:
sudo iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp -m multiport --dports 5901:5903,6001:6003 -j ACCEPT
I terminal throws this message:
iptables: Index insertion too big
What does it mean? And How can I fix this?
