Programming Forums - Pyscan V0.4

On my spare time 2 years back I decided to write a IP scanner program... this never got off it's feet really, but I did get it to work (somewhat)... I'd say it's best for Windows since it's the only platform I acctually tested it on. It's really buggy, and yah... if you want to scan IP ranges, don't use this! Heh
#Beegie_B's IP Scanner v0.4 BETA 

#Scans IP's to see if they are online 

#Now Supports Ranges

#If you want to copy this program and distribute it please give reference to me.

#This program can be used freely by anyone

import os

from os import mkdir, rmdir, remove, chdir

from time import time, ctime

  This is the BETA version of my IP scanner. Minor bugs were found

  in the scanner when used on Windows XP.

  Please report all bugs and improvement codes to: 

  webmaster@bastardshandbook.com.

  I need some people who can test this on Linux, Unix, and Mac for me.

  

  Creator: Beegie_B 

  Date: Mar 2, 2004 

  Version: 0.4 BETA 

  Tested On: Windows XP

  Changes Since v0.3 BETA: run change() to view

  ================================================================= 

  Run man() for help on use of the IP scanner.

  When running the program make sure not to close the window that

def change():

  Changes since v0.3 BETA are:



  1. Now automatically logs the scan

  2. Hostname info is included in the log



  NOTE: An HTML View of the log will be added in the next version

Have fun lookin at it
