Description:

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’).

Add a simple CLI interface.


September 12, 2011
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.


August 3, 2011
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.


March 11, 2010
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
Fixes by George Notaras,
reported by Chris Hallman:
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.


May 30, 2007
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”



December 4, 2000
Changed the struct.pack() calls to pack the checksum and ID as
unsigned. My thanks to Jerome Poincheval for the fix.


November 22, 1997
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.


December 16, 1997
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().
