I just started learning threading so I decided to make a program to ping a network. Probably not the best way to approach it. Just posted this so I can get some constructive feedback and hope to help other programmers learn python too.
#!/usr/bin/python
import subprocess
import threading
import time
import sys
def ping_it_boy(ip_addr):
p = subprocess.Popen(["ping","-n","1",ip_addr], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
for line in p.stdout.read().split("\n"):
if line.strip().startswith("Reply from "):
l = line.strip().split()
m = line.replace(l[0]+" "+l[1]+" "+l[2], "")
if m.strip() != "Destination host unreachable.":
print(l[2][:-1] + " >>> " + m)
def get_input(prompt):
"""
Function Get input from the user maintaining the python compatibility with earlier and newer versions.
:param prompt:
:rtype : str
:return: Returns the Hash string received from user.
"""
if sys.hexversion > 0x03000000:
return input(prompt)
else:
return raw_input(prompt)
if __name__ == "__main__":
ip = get_input("Enter the base IP. Example: 192.168.1 \n>>> ")
ip = ip.strip() + "."
print("Starting multiply threads for "+ ip + "0/24")
t_thread = []
t_sleep_on = 20
for i in range(1, 255):
t = threading.Thread(target=ping_it_boy, args=(ip + str(i),))
t_thread.append(t)
t.start()
if i == t_sleep_on:
for i in t_thread:
i.join()
t_thread.remove(i)
# print("Wakey Wakey")
t_sleep_on += 20
ohh btw the reason why i cut the thread by 20 is because I have a slow pc. Launching a lot of thread cause my computer to crash so I capped it at 20.

Haven't changed much except add one function. I would advise you extend this for mask or IP block and you won't need a user to give you a base IP.

Thanks! I forgot to mention that I was on python 2.7 because I was using the pyinstaller to freeze the app here and there. Thanks for making it work on python3.

I was thinking about that but didn't know how to deal with multiple nic pc yet. I will look into it and extend this further.

How about asking interface from user as commandline argument(Use argparser or something ) and then work "base ip" from there. Much nicer than asking that base ip imo.
Short example to get that base ip with interface name:
import socket
import fcntl
import struct
def get_ipbase(iface):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
ip_raw = socket.inet_ntoa(fcntl.ioctl(
s.fileno(),
0x8915,
struct.pack('256s', iface[:15])
)[20:24])
ip_ = ip_raw.split(".")
ip_base = ip_[:-1]
return '.'.join(ip_base)
#example
print get_ipbase('wlan0') #Prints e.g. 192.168.100

That's a great idea but I will be bound to unix. Well the reason why I created this was because I work for a company with very old network. All the sys admins who have more authority than me are all "windows experts". They also aren't familiar with tools like nmap lol. I created this to prove a point that they need to learn scripting to make their life easier since half the staff who knows what they are doing are gone :( I am a trainee admin, but I doubt that they can show me anything useful ahahahah.
I can probably connect to google dns and retrieve the ip automatically tough to avoid picking up the lo. The downfall is that in the future if I need to ping all devices from a nic that doesn't connect to internet than I am kind of screw. I will figure a way out and update it later. Just picked up black hat python. Very very interesting book.

if line.strip().startswith("Reply from "):
l = line.strip().split()
m = line.replace(l[0]+" "+l[1]+" "+l[2], "")
if m.strip() != "Destination host unreachable.":
print(l[2][:-1] + " >>> " + m)
def get_ip_addr():
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8",80))
ip = s.getsockname()[0]
base_ip = ip.split(".")[0] + "." + ip.split(".")[1] + "." + ip.split(".")[2] + "."
return base_ip
if __name__ == "__main__":
# ip = raw_input("Enter the base IP. Example: 192.168.1 \n>>> ")

Kind of forgot your script were for windows when I wrote my previous post(even tho I did noticed it from ping arguments+parsing). But for windows(works also in Linux and OS X ) you might wanna check netifaces (https://pypi.python.org/pypi/netifaces) module. Haven't use it myself but it seems quit useful for this kind of stuff.
edit:
Also this part of script in your last post:
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8",80))
ip = s.getsockname()[0]
I think alternative to this without querying outside server could be:
host = socket.gethostname()
ip = socket.gethostbyname(host)
This should work on Windows. I tested it with my VM windows7 and it returned correct local ip and not lo. Instead in some Linux systems it always returns '127.0.0.1'.

Thanks bro and +a cookie. netifaces looks simple enough and is very suitable for this app. I will give it a try :)
