Telnet in UNIX

[vanna]

I am doing a script which has to telnet another machine and run a program on this machine. How do you set the telnet command so that it automatically inputs the username, password and type of emulation setup?

Thanks

This website should help you accomplish what you are trying to do with telnet --

Does this have to an interactive session? If not, I would look at rexec or even better, SSH.

First of all thanks for your help - but I still have not managed to telnet the remote host bypassing the password input stage.

Any ideas?

Hi,

Maybe "expect" is a tool that can help you. Have a look at

SSH (

http://www.openssh.com/)

can be configured to remotely connect from one system to another without the use of a "password". It uses "Trusted Hosts" for authentications if you configure it correctly.

You can also setup remote commands by modifying the .rhosts and possibly /etc/hosts.equiv on both machines to allow specific connections from one system to the other with prompting for passwords.

Expect is definately the best option, since it's highly customizable...

i believed you are looking into putting a .netrc script in the user you are about to use for telnet, or try to put it inside the /etc directory instead. Try to search for .netrc configurations... by default it doesnt come with this, so you need create this file... then inside you need to place the ftp user and machine name and password as well..
hope this answers your question.
