Best introductory books for novices

[djoyce]

I'm planning to give a short course on various features used by Star-os. In particular firewalling, bandwidth control and perhaps radius. We've setup Star-os backhauls into remote communities, medical clinics, grade schools and local governments. Generally the participants are school teachers, local government leaders and computer technicians. All the participants are reasonably computer literate and have some understanding of ip networking. However all are novices to Linux. What I'm hoping for is a recommendation of a good basic book on these topics, particularly the firewalling. Hopefully at a reasonable cost since it will be charged back to the participants.
Thanks

This book has basic PC Hardware concepts and TCP/IP networking. Highly recommend it.
