How to automatically supply input to prompt when running linux ksh script?

I currently have a script that ssh's into another server and runs a command. When the ssh command runs though in prompts if I would like to connect (yes/no) and for the password. Is there a way that when the ssh call is made that I could automatically supply the input for the prompt?

Also, I do realize that using a public key with the ssh command would resolve this issue, but I do not have permission to create a public key.

Don Libes created Expect exactly so you could program tools that need to interact with prompts. I've even used it with modems! It's a very old tool but very effective, and it deserves to be more widely known.

The only downside is that it uses Tcl, which is not my favorite programming language. But to learn enough Tcl to make simple expect scripts won't take you more than an hour. And Expect is really the perfect tool for the job.

can you download and install external tools? if you can try, try sshpass. I have not tried, but you can give it a go.
