RE: UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

Hi Fabio,

 

I cannot see your reply in python-list until I search this question on Internet 
again.

 

I try (username.encode('utf-8') + '\r') and the problem is fixed.

 

Thank you very much.

You should be able to reproduce the same behavior on PyDev if in your run 
configuration you select the encoding of the console to be ascii (run  run 
configurations  select run configuration  common  set encoding to 
us-ascii).

 

My guess is that you have the problem because the username has non-ascii chars 
-- and you're receiving it as an unicode and not a string... so, you have to 
do encode it properly to a string before writing to the connection (i.e.: 
username.encode('utf-8') + '\r' -- although the encoding may have to be a 
different one and not utf-8).

 

Cheers,

 

Fabio

UnicodeDecodeError: 'ascii' codec can't decodee byte 0xff in position 0: ordinal not in range(128)

Hi all,

 

I use Python telnetlib on Windows 7 32 bit. Here is my code:

 


def telnet(self, host, os, username, password):

connection = telnetlib.Telnet(host)

connection.read_until('login: ')

connection.write(username + '\r')

connection.read_until('assword: ')

connection.write(password + '\r')

connection.read_until('', timeout = TIMEOUT)

   return connection

 

I can run the program in Eclipse and telnet successfully to a Windows host.

 

But when I export to .exe file:

 


from distutils.core import setup

import py2exe

 

setup(

options = {

py2exe:{

packages: ['wx.lib.pubsub'],

dll_excludes: [MSVCP90.dll, HID.DLL, w9xpopen.exe],

}

},

console = [{'script': ‘my_program.py'}]

)

 

and run the programe, I encounter this error:

 


UnicodeDecodeError: 'ascii' codec can't decodee byte 0xff in position 0: 
ordinal not in range(128)

 

at line:

 


connection.write(username + '\r')

 

I have debugged and searched the Internet hard but found no solution yet.

 

I think it is because of ‘\r’.

 

Do you have any idea?
