本文实例为大家分享了Python3多线程版TCP端口扫描器的具体代码，供大家参考，具体内容如下

使用命令

python BannerDemo.py -H 192.168.200.101 -p 22,3306

代码如下

import optparseimport socketfrom socket import *from threading import *screenLock = Semaphore(value=1)def connScan(tgtHost,tgtPort): try: connSkt = socket(AF_INET,SOCK_STREAM) connSkt.connect((tgtHost,tgtPort)) connSkt.send('ViolentPython\r\n'.encode('utf-8')) result = connSkt.recv(1024) screenLock.acquire() print("[+] %d/tcp open"%tgtPort) print("[+]"+str(result)) except Exception as e: screenLock.acquire() print(e) finally: screenLock.release() connSkt.close()def portScan(tgtHost,tgtPorts): try: tgtIp = gethostbyname(tgtHost) except: print("[-] Cannot reslove '%s' : Unknown host" % tgtHost) return try: tgtName = gethostbyaddr(tgtIp) print("\n [+] Scan Result for: " + tgtName[0]) except: print("\n [+] Scan Result for: " + tgtIp) setdefaulttimeout(1) for tgtPort in tgtPorts: print("Scanning port "+ tgtPort) t = Thread(target=connScan,args=(tgtHost,int(tgtPort))) t.start()def main(): parser = optparse.OptionParser("usage%prog -H <target host> -p <target port>") parser.add_option('-H',dest='tgtHost',type='string',help='specify target host') parser.add_option('-p',dest='tgtPort',type='string',help='specify target port[s] separated by comma') options,args = parser.parse_args() tgtHost = options.tgtHost tgtPorts = str(options.tgtPort).split(',') if(tgtHost == None or tgtPorts[0] == None): print("[-] You must specify a target host and port[s]") exit(0) portScan(tgtHost,tgtPorts)if __name__ == '__main__': main()
