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
pythonBannerDemo.py-H192.168.200.101-p22,3306
代码如下
importoptparse
importsocket
fromsocketimport*
fromthreadingimport*
screenLock=Semaphore(value=1)
defconnScan(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/tcpopen"%tgtPort)
print("[+]"+str(result))
exceptExceptionase:
screenLock.acquire()
print(e)
finally:
screenLock.release()
connSkt.close()
defportScan(tgtHost,tgtPorts):
try:
tgtIp=gethostbyname(tgtHost)
except:
print("[-]Cannotreslove'%s':Unknownhost"%tgtHost)
return
try:
tgtName=gethostbyaddr(tgtIp)
print("\n[+]ScanResultfor:"+tgtName[0])
except:
print("\n[+]ScanResultfor:"+tgtIp)
setdefaulttimeout(1)
fortgtPortintgtPorts:
print("Scanningport"+tgtPort)
t=Thread(target=connScan,args=(tgtHost,int(tgtPort)))
t.start()
defmain():
parser=optparse.OptionParser("usage%prog-H-p")
parser.add_option('-H',dest='tgtHost',type='string',help='specifytargethost')
parser.add_option('-p',dest='tgtPort',type='string',help='specifytargetport[s]separatedbycomma')

tgtPorts=str(options.tgtPort).split(',')
if(tgtHost==NoneortgtPorts[0]==None):
print("[-]Youmustspecifyatargethostandport[s]")
exit(0)
