Example of using python to scan ports

Python is the most concise and easy-to-understand scanning port code. It is amazing to run it.

Copy codeThe Code is as follows:
From threading import Thread, activeCount

Import socket

Import OS

Def test_port (dst, port ):

OS. system ('title' + str (port ))

Cli_sock = socket. socket (socket. AF_INET, socket. SOCK_STREAM)

Try:

Indicator = cli_sock.connect_ex (dst, port ))

If indicator = 0:

Print (port)

Cli_sock.close ()

Except t:

Pass

If _ name __= = '_ main __':

Dst = '1970. 168.0.22'

I = 0

While I <65536:

If activeCount () <= 200:

Thread (target = test_port, args = (dst, I). start ()

I = I + 1

While True:

If activeCount () = 2:

Break

Input ('finished scanning .')
