The Unix System Administration Handbook, versions 1,2,3 have been the MOST useful books I have ever had the privilege to deal with. I have kept old copies because you never know when you will find an Ultrix system that needs a serial port terminal still. From the many people who I have met who have worked with Dr? Nemeth, she is a wonderful person to have learned from... always challenging and encouraging people to meet their full potential.
Thankyou for your books.. I hope you have fun sailing.
