cannot do ping command while opensnitch is active #74

cannot do ping command while opensnitch is active, your version in @evilsocket repo. In mine it works fine but my lack improvement of non blocking connections. ways to reproduce start opensnitch run it open some apps allow some rules and then try pinging google.com for example or even IP not a fqdn.

This is an issue with us not handling ICMP at all. ICMP breaks some assumptions currently done in opensnitch (like not having sport and dport).

Here can be a good starting point for anyone interested in fixing this: https://github.com/evilsocket/opensnitch/blob/master/opensnitch/connection.py#L38

I'm seeing this problem too, running 1.4.0~rc4-1 amd64 . I cannot ping any host (including localhost) when OpenSnitch is active ... and nothing appears in the event tab to indicate that something is being blocked.
