Your p“Timeout !!!!” when I enter a known good IP address when running port scanner

[James2000k]

Can anyone offer some assistance because i am working on this port scanner and it seems to run fine but when i sent it to another person they said they are getting a time out error. If anyone doesn't mind looking at the code i can share it with them

Check code below. thanks guys and girls

#This program does the port scanning from 0 to 1025.

#All results will write in file.

#Errors is managed by exception and will write to file.



import concurrent.futures

import socket

import threading

import time

import sys







print_lock = threading.Lock()



ip = input("Enter the IP to scan: ") #ask user ip for scanning



f = open("scanresult.txt", "w") #open file to write results

print("Scanned IP: ", ip, file=f)





def scan(ip, port):

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

    scanner.settimeout(1)

    try:

        scanner.connect((ip, port))

        scanner.close()

        with print_lock:

            print(f"[{port}]" + f" is open", file=f)

    except KeyboardInterrupt: #manage exception

        print("\n Exiting Program !!!!", file=f)

        sys.exit()

    except socket.gaierror:

        print("\n Host name Could Not Be Resolved !!!!", file=f)

        sys.exit()

    except socket.herror:

        print("\n Host is not available !!!!", file=f)

        sys.exit()

    except socket.timeout:

        print("\n TIMEOUT !!!!", file=f)

        sys.exit()

    except:

        pass



startscan = time.time() #time when scan started

print(time.ctime(), file=f) #print date and time when scan started

with concurrent.futures.ThreadPoolExecutor(max_workers=100) as executor: #actual scanning

    for port in range(1025):

        executor.submit(scan, ip, port + 1)

        break

    

endscan = time.time() #time when scan ended

print(time.ctime(), file=f) #print date and time when scan ended

print("Scan time is: ", int(endscan) - int(startscan), file=f)



f.close() #close file after writing





scan(ip, port)
