Problem in connecting nodes of Cisco Terminal Server

[abhijitbakale]

I have several devices connected to cisco Terminal Server and while I am trying to reach out to those nodes, I am not about to get in.

The code: from Exscript.util.interact import read_login from Exscript.protocols import Telnet

account = read_login() conn = Telnet(debug=5) conn.set_driver('ios') conn.connect('192.100.101.201', 2042) conn.login(account) conn.execute('conf t') conn.send('exit\n') conn.close()

Output Traceback Stack:

please enlighten me if I am doing anything wrong.

You'll have to implement your own driver. The ios driver in this package doesn't handle ANSI escape codes. (posting this in case someone comes across a similar issue in the future).
