实现简单探测：使用socket模块，connect()方法建立与指定IP和端口的网络连接；revc(1024)方法将读取套接字中接下来的1024B数据
import socket
import sys
socket.setdefaulttimeout(2)
s=socket.socket()
s.connect(('192.168.1.1',21))
ans=s.recv(1024)
print(ans)通过函数实现：通过def()关键字定义，示例中定义扫描FTP banner信息的函数
import socket
def retBanner(ip,port):
try:
socket.setdefaulttimeout(2)
s = socket.socket()
s.connect((ip,port))
banner = s.recv(1024)
return banner
except:
return
def checkVulns(banner):
if 'vsFTPd' in banner:
print '[+] vsFTPd is vulnerable.'
elif 'FreeFloat Ftp Server' in banner:
print '[+] FreeFloat Ftp Server is vulnerable.'
else:
print '[-] FTP Server is not vulnerable.'
return
def main():
ips = ['10.10.10.128','10.10.10.160']
