telnet求助

大家好！

1. import getpass
   
2. import time
   
3. import sys
   
4. import telnetlib
   
5. 
   
6. HOST = "localhost"
   
7. PORT = 1981
   
8. user = raw_input("Enter your remote account: ")
   
9. password = getpass.getpass()
   
10. tn = telnetlib.Telnet(HOST,PORT)
    
11. try:
    
12.         tn.read_until("username: ")
    
13. except EOFError:
    
14.         print 'username:error'
    
15. tn.write(user + '\n')
    
16. if password:
    
17.     try:
    
18.         tn.read_until("password: ",30)
    
19.     except EOFError:
    
20.         print 'password:error'
    
21.     print password
    
22.     tn.write(password+'\n')
    
23. 
    
24. tn.write("help\n")
    
25. tn.write("exit\n")
    
26. 
    
27. print tn.read_all()

复制代码

# python telnet.py
Enter your remote account: admin
Password:
password:error
123456

tn.read_until("password: ",30)这里报的异常，是tn.write(user + '\n')没有发送成功吗？

>telnet localhost 1981
username: admin
password:

用\r 替换\n可以么？
