Let us tie up a few loose ends: you should be aware that changing telnetd -a valid to telnetd -a user will allow users to login without authentication. If they don't run kinit, they won't even get a login prompt if you use telnet -a valid. Remember, since the passwords are stored on your KDC, make sure no one breaks into it; otherwise, they will have access to all the machines to which the KDC grants access. Get to know the terms principal, realm, kdc, etc.—almost anything you come across will use them.
Well, you most likely feel I've left out a lot—and you are right, I have. There is plenty more to learn and plenty more to try. The MIT webpage has tons of links to more information. Of course, you can always e-mail me and ask me, and I'll try to answer you quickly.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
