Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - James2000k - May-13-2022 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) RE: Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - buran - May-13-2022 Why didn't you share the code (minimal reproducible example)?

The program stalls and the response from the instructor after running the program was "Your program gives me a “Timeout !!!!” when I enter a known good IP address." Below is what the program does it just sits there with no output after you enter a IP address. Python 3.9.5 (v3.9.5:0a7dcbdb13, May 3 2021, 13:05:53) [Clang 12.0.5 (clang-1205.0.22.9)] on darwin Type "help", "copyright", "credits" or "license()" for more information. >>> = RESTART: /Users/james2000k/Library/Containers/com.apple.mail/Data/Library/Mail Downloads/6259D512-5E2F-4F5B-8F7B-E6224753CF0F/port_scan_socket.py Enter the IP to scan: 172.*.*.* >>> RE: Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - Larz60+ - Jul-01-2022 Quote:Thanks for the response. I posted what the output was but to be honest there isn't any other than the fact that it shows timeout Please do not send private mail when the community will benefit from your query. There are many port scanners available, you will have to try until you find one that meets your needs.

RE: Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - buran - Jul-18-2022 Your function expects an argument def scan(ip): , then at the end you have scan() , i.e. you don't supply the expected argument. What do you expect to happen?That said, there are also other problems - e.g. when using ThreadPoolExecutor. RE: Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - James2000k - Aug-06-2022 At this point this program that i posted probably has too many bugs to fix. So can anyone either send or post a simple port scanner that will write results to a file. I have to go back and revisit this one with the bugs but for a quick fix i will use a working one if someone has or knows where i can find one thank you RE: Your p“Timeout !!!!” when I enter a known good IP address when running port scanner - Larz60+ - Aug-06-2022 see post 5: https://python-forum.io/thread-37213-post-159011.html#pid159011 It has a links to all PyPi packages related to port scanning.
