python 套接字，sock.connect 错误

Question

import socket
from datetime import datetime

#User input
ServerIP = raw_input("Enter server IP: ")
RemoteServerIP = socket.gethostbyaddr(ServerIP)

print "-" * 60
print "Please wait, scanning remote host", RemoteServerIP
print "-" * 60

#Starting to scan
StartTime = datetime.now()

for port in range(1,1025):#ports 1-1024
    sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    result = sock.connect_ex((RemoteServerIP, port))
    if result == 0:
        print "Port {}: \t Open".format(port)
sock.close()

#caculate the time and print to screen
EndTime = datetime.now()
TotalTime =  StartTime - EndTime 
print 'Scanning Completed in: ', TotalTime

错误:

    result = sock.connect_ex((RemoteServerIP, port))

File "C:\Python27\lib\socket.py", line 228, in meth

    return getattr(self._sock,name)(*args)

TypeError: coercing to Unicode: need string or buffer, tuple found

Answer 1

socket.gethostbyaddr() returns a tuple 。访问ipaddrlist中的第一项应该可以满足您的需要:

RemoteServerIP = socket.gethostbyaddr(ServerIP)[2][0]
