A pure python ping implementation using raw sockets.
Note that ICMP messages can only be sent from processes running as root (in Windows, you must run this script as 'Administrator').

Bugfixes + cleanup by Jens Diemer Tested with Ubuntu + Windows 7
September 6, 2011
Cleanup by Martin Falatic. Restored lost comments and docs. Improved functionality: constant time between pings, internal times consistently use milliseconds. Clarified annotations (e.g., in the checksum routine). Using unsigned data in IP & ICMP header pack/unpack unless otherwise necessary. Signal handling. Ping-style output formatting and stats.

Ported to py3k by Zach Ware. Mostly done by 2to3; also minor changes to deal with bytes vs. string changes (no more ord() in checksum() because >source_string< is actually bytes, added .encode() to data in send_one_ping()). That's about it.

changes by Samuel Stauffer: replaced time.clock with default_timer which is set to time.clock on windows and time.time on other systems.
November 8, 2009
Improved compatibility with GNU/Linux systems.
Changes in this release:
Re-use time.time() instead of time.clock(). The 2007 implementation worked only under Microsoft Windows. Failed on GNU/Linux. time.clock() behaves differently under the two OSes.

little rewrite by Jens Diemer:
- change socket asterisk import to a normal import
- replace time.time() with time.clock()
- delete "return None" (or change to "return" only)
- in checksum() rename "str" to "source_string"

Changed the struct.pack() calls to pack the checksum and ID as unsigned. My thanks to Jerome Poincheval for the fix.

Initial hack. Doesn't do much, but rather than try to guess what features I (or others) will want in the future, I've only put in what I need now.

For some reason, the checksum bytes are in the wrong order when this is run under Solaris 2.X for SPARC but it works right under Linux x86. Since I don't know just what's wrong, I'll swap the bytes always and then do an htons().
