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

[James2000k]

Why didn't you share the code (minimal reproducible example)?

Hi Buran

I guess rookie at this but here it is below


#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)
