在python的telnet客户端服务器中有问题

Question

我想用python制作telnet服务器。

这是我的服务器代码：

#!/usr/bin/python
import socket

SK = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
HOST = "192.168.1.10"
PORT = 23

SK.bind((HOST, PORT))
SK.listen(5)

(Attacker_connection, (Attacker_IP, Attacker_PORT)) = SK.accept()

while True:
    Command = Attacker_connection.recv(4096)
    Command = Command.decode("ascii")
    if Command == "Quit":
        break

和客户端测试命令：

  

telnet 192.168.1.10

但是服务器错误：

Traceback (most recent call last):
  File "Telnet_H.py", line 18, in <module>
    Command = Command.decode("ascii")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

客户端错误：

Trying 192.168.1.10...
Connected to 192.168.1.10.
Escape character is '^]'.
Connection closed by foreign host.

为什么会这样，我该如何解决？
