Description:

I need to run a program on many different machines at once. The only way I can get into them is rlogin (and it doesn't prompt me for the password when I log in). I'd like to automate (using perl) logging into a list of machines and running a program on each.

Note that the program I want to launch is interactive, including an X Windows GUI.

Since you have rlogin, you should also have rsh. So:

qx( rsh $host "$command" );

You can use Expect:

Expect->spawn("/usr/bin/rlogin -l $user $host");
