telnetlib python example

Question

So I'm trying this really simple example given by the python docs:

import getpass
import sys
import telnetlib

HOST = "<HOST_IP>"
user = raw_input("Enter your remote account: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

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()

My issue is that it hangs at the end of the read_all()... It doesn't print anything out. I've never used this module before so I'm trying to get this really basic example to work before continuing. BTW, I'm using python 2.4 Thank you.

Answer 1

Okay, I found a solution. Before I entered ls and exit, I needed to first specify the terminal type. Adding

tn.write("vt100
") 

before the "ls" fixed the problem for me.
