[Script] Python port scanner using multi-threading.

[Guest]

import socket
import threading

def scan(target, port):
    sockets = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sockets.settimeout(5)
    scan = sockets.connect_ex((target, port))
    if scan == 0:
        print(f"Port > {port} open")
    sockets.close()

def ports(target):
    threads = []
    for port in range(1, 65535):
        t = threading.Thread(target=scan, args=(target, port))
        threads.append(t)
        t.start()
    for t in threads:
        t.join()

target = input("Enter the target address: ")
ports(target)

so this starts 65535 in a loop, what happens if there are a lot running at once? could it crash?

if i remember correctly, threads run independently until the target function returns or the .join() is called

this look like single ip port scanner, i think this script not support ip range like 192.168.1.1-192.168.1.255
and for port in range(1 to 65535) whats the point of extra ports?? not work good crash or stuck

Correct feel free to implement it i just wrote the script messing around.

oh sorry bro, if you code this , then i am sorry
i appreciate your work.

No worry's a little constructive criticism never hurts.

Here is a more accurate one in terms of scanning. i wrote after i hallucinated.​

import socket
import threading
import ipaddress

# function to check if an IP address is reachable
def is_reachable(ip):
    reachable = False
    try:
        # ping the IP address
        response = os.system("ping -c 1 " + ip)
        if response == 0:
            reachable = True
    except:
        pass
    return reachable

# function to scan a range of ports for a given IP address
def scan_ports(ip, ports, results):
    for port in ports:
        try:
            # create a socket object
            s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            # set a timeout for the connection attempt
            s.settimeout(0.5)
            # try to connect to the port
            result = s.connect_ex((ip, port))
            # if the connection attempt is successful, add the open port to the results list
            if result == 0:
                banner = s.recv(1024)
                results.append((ip, port, banner))
            # close the socket
            s.close()
        except:
            pass

# function to perform a brute force scan of a range of IP addresses and ports
def brute_force_scan():
    # prompt the user to input the IP range to scan
    while True:
        try:
            ip_start = input("Enter the starting IP address to scan (e.g. 192.168.0.1): ")

            ip_end = input("Enter the ending IP address to scan (e.g. 192.168.0.255): ")
            ipaddress.IPv4Address(ip_end)

            if port_start <= port_end and 1 <= port_start <= 65535 and 1 <= port_end <= 65535:
                port_range = (port_start, port_end)
                break
            else:
                print("Invalid port range. Please try again.")
        exceptValueError:
            print("Invalid port number. Please try again.")

    # create a list to store the results of the scan
    results = []

                t = threading.Thread(target=scan_ports, args=(ip_str, [port], results))
                # add the thread to the list

Слишком упрощённая версия, это больше пример для новичков чем полезный к изучению код.
Сделай получение банеров служб хотя бы, что бы как то разнообразить этот сканер.

An overly simplified version, this is more of an example for beginners than useful code to learn.
Get service banners at least to diversify this scanner.

you can update this script, ask chatgpt lol

chatgpt is not needed here, this is the basics of the python language, if you do not know elementary things, then even chatgpt will not help to make a normal scanner.
