Hi,

i am a little bit new in securecrt scripting , i have a task to access to many devices trying different usernames and passwords , i am trying the below script but i think it stuck in the while loop so i cannot execute the rest of the code.

please advise on this issue.

# $language = "python"
# $interface = "1.0"

# Connect to an SSH server using the SSH2 protocol. Specify the
# username and password and hostname on the command line as well as
# some SSH2 protocol specific options.

import csv
import SecureCRT, sys, os
import time

	vPossibleResponses = [\
        			"sername",
					"assword",
        			"Access denied",
				"Authentication failed"
				]

	while True:
        	crt.Screen.WaitForStrings(vPossibleResponses)
        	if crt.Screen.MatchIndex > 0:
            	strStringFound = vPossibleResponses[crt.Screen.MatchIndex - 1]

		if crt.Screen.MatchIndex == 1:

            		crt.Screen.Send("xx\r")

		elif crt.Screen.MatchIndex == 2:
			 crt.Screen.WaitForString("ssword:", 1)
			 crt.Screen.Send("xx\r")
