Sorry, this may seem like a dumb question but where do I get the secure module?

how to execute a script from a local server on a remote server?

@chrisotter92, you dont need to know about the secure module. It seems that on line 10-11 matt is just using the secure module to extract the username and password as strings.

You should already know the username and password, which you can provide, without invoking the secure module

@Arnold1.. this is exactly what the script is doing using the pexpect library:https://github.com/pexpect/pexpect
