UNIX for Advanced & Expert Users

Hi there,


I got a big problem.
For one of our customers I did a website (php) that connects to another machine "A" (server) to machine "B" via expect.

Now he wants that after the the connection with "B" is established, a telnet connection to "C" is opened, and some commands are executed. The results need to be retrieved too.

The problem is, it's not so easy to start telnet from a shell, since you only can give the username with it when its started but not the password. We don't have any permissions to install anything on "B" nor "C"; we could put a script on "B" though to connect with "C".

Does anyone have a shell skript that connects to another machine via telnet? Or a php skript which connects from "A" to "B" to "C"?

Any ideas on this? I'm going nuts about this ...


Thanks for your help!

try rlogin (which need to edit file /etc/hosts.equiv) so,
use man rlogin or rcmd

Okay.... in the script:

$host = "your_'c'_machine_here";

exec("telnet $host", $output);

et voila!

Now, if you want to interface directly with telnet, you can make a simple form with <textarea>'s and <input type="text">'s to interface with telnet via the $output array, and maybe a JavaScript that will auto-refresh the browser every 10 seconds or whatnot.
