How do I do an interactive rlogin in Perl?

senor_fjord has asked for the wisdom of the Perl Monks concerning the following question:

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" );` [download]	[reply] [d/l]
