iptstate - Display IPtables state information in a "top"-like interface

iptstate (IP Tables State) implements the "state top" feature from IP Filter for IP Tables. "State top" displays the states held by your stateful firewall in a "top"-like manner. Since IP Tables doesn't have a built-in way to easily display this information once, an option was added to iptstate to do this.

The only requirements are a curses library (usually ncurses), and libnetfilter_conntrack version 0.0.50 or later

Installation:
OpenSuSe user can install iptstate using "1-click" installer - here
Ubuntu user can install iptstate - here

After successful installation, go to terminal and type command:  iptstate to open up the application and if netfilter CONNTRACK is enabled in the kernel.
