# python GUI example using Tkinter # Everyone likes to ping servers and what # not so this example is a front end # to the well used ping command. # # Python has quite a few different # frameworks to choose from.

Python - Tkinter frontend example to ping

Python - pure python ping using raw sockets
# I've searched the web far and wide. I've written my own# os.popen() version to ride an operating system's ping.# I finally found a pure raw ping implementation in python# that seems to work!## I copied the entire page from:# http://svn.pylucid.net/pylucid/CodeSnippets/ping.py#########################################################

"""
A pure python ping implementation using raw socket.
Note that ICMP messages can only be sent from processes running as root.
Derived from ping.c distributed in Linux's netkit. That code is
copyright (c) 1989 by The Regents of the University of California.
That code is in turn derived from code written by Mike Muuss of the
US Army Ballistic Research Laboratory in December, 1983 and
placed in the public domain. They have my thanks.
Bugs are naturally mine. I'd be glad to hear about them. There are
certainly word - size dependenceies here.

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

Python - ping one or many addresses at once
