python实现端口扫描器
设计今下午终于验收了，╰(°▽°)╯
本文主要实现一个带界面的端口扫描器
一篇特别好的博客https://thief.one/2018/05/17/1/
扫描原理
端口扫描方式主要以下几种：tcp全连接、tcp syn、fin、udp扫描
TCP全连接扫描
利用tcp的三次握手，如果能建立连接，则说明端口开放。扫描过程：
如果该端口是开放的，就能完成TCP三次握手。但是这些样会记录发送者的IP地址，所以很容易被发现。本次使用socket实现这种扫描。
TCP SYN扫描
不建立完整的TCP连接。端口扫描工具生成一个SYN包，如果目标端口开放，则会返回 SYN-ACK 包，扫描端回应一个RST包，然后在握手完成前关闭连接。
关于实现有以下几个设想：
- 开始本来想使用原生套接字实现，但是出现各种原因
- 后来又想借助impacket构造包，再用原生套接字发送，但是也存在问题
- 最后只好使用scapy，确实简单方便不少，最后成功
FIN扫描
发送FIN包，如果响应RST包，则端口是关闭的
UDP扫描
发送udp包，如果没有响应，可能是开放的
遇到的问题
QT desinger 设计ui界面
参考：
http://code.py40.com/2561.html
QProgressBar使用
如果将进度条的最大最小值设为0，则进度条会变为繁忙状态，参考：
https://blog.csdn.net/liang19890820/article/details/52302879
QT界面运行假死
运用线程，主界面一个线程，处理程序一个线程，中间通过信号传递消息。参考:
https://www.jb51.net/article/176310.htm
https://zhuanlan.zhihu.com/p/62988456
https://www.jianshu.com/p/ed47a8959854
https://blog.csdn.net/djstavav/article/details/88942098
QT界面转换为代码
开始配过pyuic，可以直接转换，但是重装了pycharm后没有了，重新配置后出现问题，所以采用如下命令，将设计好的界面转换为代码：
pyuic5 -o my.py my.ui
socket编程
参考：
https://www.liaoxuefeng.com/wiki/1016959663602400/1017788916649408
原始套接字
参考：
https://blog.csdn.net/u011580175/article/details/80761274
该文说原始套接字在win10不可使用，但是我验证可以使用，只是运行程序时需要管理员权限，但是用原始套接字自己构造包最后有错误，还是不能完成程序，可能是构造包时出现问题，主要是如下报错
WinError 10022 提供了一个无效的参数
python-nmap使用
python-nmap是一个可以在Python程序中使用nmap端口扫描器的Python包。参考：
https://www.cnblogs.com/aylin/p/5996229.html
https://blog.csdn.net/qq_36119192/article/details/83717690
impacket使用
https://blog.csdn.net/CubieLee/article/details/105041275
使用impacket最后能发出包，但是不太对，可能是构造包还是有问题
scapy使用
https://zhuanlan.zhihu.com/p/51002301
https://www.jianshu.com/p/025337816217
导入包时出现如下报错，可能是包中命名与其它有错误，将导入它的语句放在了导入其它包语句的前面就解决了
'module' object is not callable
IPy使用
主要用于分割cidr类型的ip段，参考
https://www.cnblogs.com/cherishry/p/5916935.html
扫描实现
最简单的全连接扫描
import sys
from socket import *
host = sys.argv[1]
portStr = sys.argv[2].split('-')
startPort = int(portStr[0])
endPort = int(portStr[1])
openPort = []
ip = gethostbyname(host)
for port in range(startPort, endPort + 1):
# 创建套接字，第一个为协议族名，第二个为套接字。TCP套接字的名字SOCK_STREAM，UDP套接字的名字SOCK_DGRAM
sock = socket(AF_INET, SOCK_STREAM)
sock.settimeout(10)
#s.connect()主动初始化TCP服务器连接。一般address的格式为元组（hostname,port），如果连接出错，返回socket.error错误。
#connect_ex()为connect()函数的扩展版本,出错时返回出错码,而不是抛出异常
result = sock.connect_ex((ip, port))
if result == 0:
openPort.append(port)
print("开放的端口有")
for port in openPort:
print(port)
多线程的全连接扫描
使用多线程加快扫描速度
import sys
import _thread as thread
from socket import *
def scan(port):
sock = socket(AF_INET, SOCK_STREAM)
sock.settimeout(10)
result = sock.connect_ex((ip, port))
#print输出时候需要加锁，如果不加锁可能会出现多个输出混合在一起的错误状态，而锁需要在程序启动时创建，从而能让新建的线程共享这个锁：
if result == 0:
lock.acquire()
print("开放的端口", port)
lock.release()
if __name__ == '__main__':
host = sys.argv[1]
portStr = sys.argv[2].split('-')
startPort = int(portStr[0])
endPort = int(portStr[1])
ip = gethostbyname(host)
#创建锁
lock = thread.allocate_lock()
for port in range(startPort, endPort + 1):
#创建线程
thread.start_new_thread(scan, (port,))
带界面的端口扫描器
支持对一个ip或者一个ip段的一个端口或者端口范围进行全连接、syn、nmap扫描。
并且采用多线程提高扫描速度，可以设置扫描间隔进一步提高隐蔽性，最后可以将扫描结果保存为文件。
