Shell Programming and Scripting

Dear friends,

Could you please help me in writing a sample code to connect the remote system (through ssh) using expect in shell script.

Thanks in advance.. :-)

The proper way to use ssh automatically is with keys. Google "passwordless ssh" and you'll find dozens of tutorials all over the internet. "interactive password authentication" means "password typed by a human being in realtime authentication" and nothing else is supposed to do.

That's why it's such a hassle to do this, why you have to use a third-party brute-force hacking utility like expect to even try -- the program designers were helpful enough to design this -- and many other login systems -- in this manner to prevent you from easily making this mistake. It's a very, very bad idea to inject passwords on a regular basis. It's almost impossible to keep retrievably-stored passwords safe.
