that means we have to interpret the ip header within the icmp data, which is done by converting
IcmpData::raw_data to a stream which is fed to IpvXHeader.read
Also means that address to test for has to be forwarded to IcmpDestinationUnreachableData
and cannot be simply tested in IcmpData already --> change function prototype in all IcmpData classes

new: IcmpPacket has an IpHeader, an IcmpHeader which represents only the common first 4 byte of ICMP v4/v6, and IcmpData which is either a IcmpEchoData for echo request/reply or a IcmpDestinationUnreachableData

tried to abstract away as much as possible (for a lay programmer like me) the difference between v4 and v6

Christian Herdtweck [Wed, 21 Jan 2015 17:04:06 +0000]
remember pings based on host, not IP; correct logging logic in main loop

9 years agoremoved assert that does not make sense and is often violated
Christian Herdtweck [Wed, 21 Jan 2015 12:51:16 +0000]
removed assert that does not make sense and is often violated

(IPs are not updated very often, so can easily happen that an IP's TTL was reached.
 It is easier to ignore these cases than to avoid them, IPs will with next test be updated.)
