[Tutor] python telnet

[Rayon]

Hi all got my code to work. 
I used an in queue and an out queue passed it to the telnet session . 
I am sending commands to the in_q  using sockets and passing them back data
with the out_q. 
Below is the code for a nonstop python telnet session. 
Thanks for the help, it got me thinking and that was worth it. 

def end_less():
    """
    Start telnet session and never stop it :) 
    """
    global host
    global cmd_q
    global out_q 
    message = """
        HLR DOWN ERROR
        """
    try: 
        hia_tel = telnetlib.Telnet(host)
        hia_tel.set_debuglevel(1)
        hia_tel.read_until("login:")
        hia_tel.write('maint'+"\r")
        hia_tel.read_until("Password:")
        hia_tel.write("maint"+"\r")
        hia_tel.read_until("maint at atcaHLRds0 /public/users/maint>")
        while 1:
          try: 
            command = cmd_q.get()
            hia_tel.write(command+"\r")
            data = hia_tel.read_until("maint at atcaHLRds0
/public/users/maint>")
            out_q.put(data)
          except Exception,error:
            error_email_mis(message)
            logs('error',str(error),'null')
            end_less()
            time.sleep(10)
    except Exception,error:
        error_email_mis(message)
        logs('error',str(error),'null')

Thanks but still not working, I am wondering if I need to give the script
some kind of special permission to execute on windows 7.

traceback has:
 child = winspawn('telnet 192.168.0.55:210')

When using telnet from CLI (on windows), you would type:
telnet 192.168.0.55 210

Note the space between the IP and port number and not a :colon.

Not sure this is your problem but probably worth mentioning.
