I kinda wish the browsers error page would do this. I want it to give a brief summary of: * Was the TCP connection established. * Was an ICMP error sent back

I kinda wish the browsers error page would do this. I want it to give a brief summary of: * Was the TCP connection established. * Was an ICMP error sent back (ie. Connection refused) * Is the host pingable * Is any other host pingable. * Does the local machine have an IP address. * What did the DNS response look like. Etc. Obviously all that lot should probably be under a 'stats for nerds' title.
