Question

我正在尝试制作一个端口扫描程序，用于搜索输入端口，该端口是针对10-255范围内所有奇数编号的IP地址输入的。

我当前的代码无效，我收到此错误;

error  str, bytes or bytearray expected, not int

我认为s.connect((int(ipaddress.ip_address(my_net[i])), port))会解决这个问题，但事实并非如此。

我错过了什么吗？

我目前的代码如下：

import socket
import ipaddress
import subprocess
import sys
from datetime import datetime
#define the subnet to scan
subnet=input("which subnet are you scanning, please enter in x.x.x ")

my_net =[]
count =0
for i in range(11,255):  
    if i%2!=0:
        my_net.insert(count,(subnet+"." +str(i)))

print("Your selected network is " , subnet , "below are the usable Ip addresses")
#the user is to select the port that will be scanned as a part of the test
port = input("Enter the number of the port you would like to scan ")
# Print a banner with information on which host we are about to scan
print ("-" * 60)
print ("Please wait, scanning network" , subnet ,".0/24")
print ("-" * 60)
#check time now#
t1 = datetime.now()
#output. Confirm if the port is open or closed

for i in range(len(my_net)):
        try:
            socket.setdefaulttimeout (2)
            s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            s.connect((int(ipaddress.ip_address(my_net[i])), port))
            banner=s.recv(1024)
            print(banner)
        except Exception as e:
            print("error " , e)

# Checking the time again
t2 = datetime.now()
# Calculates the difference of time, to see how long it took to run the script
total =  t2 - t1
print ('Scanning Completed in: ', total)

我想你会发现ip地址必须是一个字符串。例如'127.0.0.1'不是int，但端口是int。

如何让我的端口扫描仪工作
