This is a node.js module for controlling iptables. It's very basic just for what we need at http://browserling.com. It was written by Peteris Krumins (peter@catonmat.net, @pkrumins on twitter). His blog is at http://www.catonmat.net -- good coders code, great reuse. ------------------------------------------------------------------------------ Here is an example usage: var iptables = require('iptables'); iptables.allow({ protocol : tcp, src : '10.1.1.5', dport : 34567, sudo : true }); iptables.drop({ protocol : 'tcp', dport : 34567, sudo : true }); This allows connections to port 34567 from 10.1.1.5 and drops connections from the same port from everyone else. ------------------------------------------------------------------------------ Ps. I once wrote an article on iptables on my blog, check it out: http://www.catonmat.net/blog/traffic-accounting-with-iptables Sincerely, Peteris Krumins (twitter: @pkrumins) http://www.catonmat.net
