请大家帮我看一个端口扫描的python 脚本，为什么打印出来都是22端口。

这个是？ 不在这里面？ 这个是手动创建的，用另外的脚本，里面添加了些端口和描述import shelve
def create():
shelf = shelve.open("security.data", writeback=True)
shelf['desc'] ={}
shelf.close()
print "Dictionary is created"
def update():
shelf = shelve.open("security.data", writeback=True)
data=(shelf['desc'])
port =int(raw_input("Enter the Port: "))
data= raw_input("\n Enter the description\t")
shelf.close()

是不是 myThread 这个类没 start() ? 101 行，
看错了，你是继承 threading不过你那个 run() 有运行？ threading.Thread
class Thread(builtins.object)
|A class that represents a thread of control.
|
|This class can be safely subclassed in a limited fashion. There are two ways
|to specify the activity: by passing a callable object to the constructor, or
|by overriding the run() method in a subclass.
问题不在那里，问题出在
def scantcp(threadName,rmip,r1,r2,c):
try:
for port in range(r1,r2):
sock= socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#sock= socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
socket.setdefaulttimeout(c)
result = sock.connect_ex((rmip,port))
screenLock.acquire()
if result==0:
print "Port open:-------->\t",port,"--",data.get(port,"Not in database")
sock.close()
screenLock.release()
我扫描从1-1000的端口，但是print "port" 的值总是打印出来是22. 回复 5# hmchzb19
我直接把你的 scantcp 运行是可以扫描的，问题应该是你的类那边的 run() 问题？ 你试着跑一下脚本就知道问题在哪里了。
