Login To Various Devices

I'm trying to create a script that will login to various cisco devices. They all have the same username / password but the login method can be SSH or Telnet. I have pasted the current script I have been using. This has worked for the most part. The biggest problem is, after I have logged into a device, and the device times out, I get a script error popup for every one. It says:

ScriptError - Error: Connection Lost
File: C:blahblahblah/python.py Line 14
crt.Screen.WaitForString("sername:" or "login:")

I'm mostly looking for a way to do some error checking in the script to eliminate this constant error. I would love to be able to try SSH and fail back to Telnet if SSH is not available if possible too. Any suggestions would be appreciated.

The current script:
________________________________________

# $language = "Python"
# $interface = "1.0"

# Login to Cisco Devices


def main():

crt.Screen.Synchronous = True
#The above waits for a command prompt

crt.Session.Connect

crt.Screen.WaitForString("sername:" or "login:")
crt.Screen.Send("USERNAME\r")

crt.Screen.WaitForString("word:")
crt.Screen.Send("PASSWORD\r")

crt.Screen.Synchronous = False


main()

Hi tunes4life,

What version of SecureCRT are you running? On what platform?

How do you run the script?

Please list the explicit steps involved.

Elaborate on worked for the most part because this does not really seem like proper syntax to me. :)

In particular, I'm thinking you want to use WaitForStrings() (plural) instead of this line:

crt.Screen.WaitForString("sername:" or "login:")

I think with the syntax you have used the script would only be waiting for that first literal (sername:).

Is this a complete script? (Other than masking credentials, which is fine.) Or have you just posted part of it?
