Telnet到节点

Question

我正在尝试通过Python Telnet代码Telnet到节点，但是这需要我输入密码，然后挂起，或者出现错误消息：“管道损坏（err 32）”或“套接字超时（err 61）” 如果一切顺利的话。输入密码后，代码会挂起很长时间，并显示“超时”错误。我不确定是什么问题。请帮助我

我尝试捕获异常并更改端口。 我尝试了Python Idle和命令提示符，但是代码不起作用 我可以通过终端手动登录到节点，而无需输入代码

import getpass
import sys
import telnetlib

HOST = "135.250.64.125"

user = input("Enter your remote account: ")

password = getpass.getpass()

tn = telnetlib.Telnet(HOST,5024)

tn.read_until("login: ")

tn.write(user + "")

if password:
    tn.read_until("Password: ")
    tn.write(password + "")

# tn.write("ls ")
#
# tn.write("exit")

print( tn.read_all())

要登录到节点并获得终端输出

我得到的错误
