  • Renamed to python3-ping for Python 3 by Mohammad Emami on PyPI and GitHub.

March 19, 2013

  • Fixing bug to prevent divide by 0 during run-time.

January 26, 2012

  • Fixing BUG #4 - compatibility with python 2.x [tested with 2.7]

    Packet data building is different for 2.x and 3.x because of the string/bytes difference.

  • Fixing BUG #10 - the multiple resolv issue.

    When pinging domain names instead of hosts (for example google.com) you can get different IP every time you try to resolve it, we should resolve the host only once and stick to that IP.

  • Fixing BUGs #3 #10 - Doing hostname resolution only once.

  • Fixing BUG #14 - Removing all global stuff.

    You should not use global! It's bad for you...and its not thread safe!

  • Fix - forcing the use of different times on Linux/Windows for more accurate measurements. (time.time for Linux and time.clock for Windows)

  • Adding quiet_ping function - This way we'll be able to use this script as external lib.

  • Changing default timeout to 3s. (1second is not enough)

  • Switching data size to packet size. It's easier for the user to ignore the fact that the packet header is 8b and the datasize 64 will make packet with size 72.

  • Bugfix if host is unknown

Merge sources and create a separate GitHub repository:

  • https://github.com/jedie/python-ping

Add a simple CLI interface.

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().
