A pure python ICMP ping implementation using raw sockets

Project 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’).

Use as a cli tool:

$ sudo pyping

PYTHON-PING ( 55 data bytes
241 bytes from ( icmp_seq=0 ttl=55 time=64.5 ms
241 bytes from ( icmp_seq=1 ttl=55 time=67.7 ms
241 bytes from ( icmp_seq=2 ttl=55 time=66.6 ms PYTHON PING Statistics----
3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip (ms)  min/avg/max = 64.457/66.244/67.677

$ pyping --help

Use as a Python lib:

>>> import pyping
>>> r ='')                # Need to be root or
>>> r ='', udp = True)    # But it's udp, not real icmp
>>> r.ret_code
>>> r.destination
>>> r.max_rtt
>>> r.avg_rtt
>>> r.min_rtt
>>> r.destination_ip

Fork this repo on GitHub and send pull requests. Thank you.



  • Cleanup projet (by toxinu): - Add Cli parser - Can be used as python library - Added to pypi - Some Fixes - Clean



  • Merge sources and create a seperate github repository and add a simple CLI interface.


  • Bugfixes + cleanup by Jens Diemer. Tested with Ubuntu + Windows 7.


  • 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.


  • Fixes by George Notaras, reported by Chris Hallman: - Improved compatibility with GNU/Linux systems. - 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.


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().


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.
