Without looking carefully at your code/logs, I'd suspect that an OS or network firewall is getting in the way. Would this apply in your case? I'm not an expert in firewalls but this might tell you what any Linux level firewall is doing: $ sudo iptables -L Here is what that command reports on a "wide open" Debian system of mine: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination -Brett.
