Executing Linux Commands from TC.

My script (JS) needs to cover environment setup. For that i need to

1. "SCP" a file to a Linux box.

2. "SSH" to that linux box.

3. Execute commands on that server.

I am sure people has resolved this kind of issue before. May be i haven't got the proper documentation yet.

And here is the link what i've tried so far.

Note: My current system in Win7.

Hope to get some direction/pointer from SMARTBEAR.

Thanks.
