VeeJay, you've asked several questions now to this list that are very
simple to solve with even a minimal amount of reading through Google.
Some people more generous than I have given you the answers, which are
are immediately met with further questions, most of which are answered
in the first part of the man page for the relevant program.
I, and I suspect other posters on this list, have little interest in
reading Unix for Dummies to you. Technical questions about specific
failures are one thing, but you're asking things that are covered in any
decent Unix / FreeBSD book. Heck, you can even get the FreeBSD Handbook
for free online.
Please, please, PLEASE RTFM. If that's too much to ask, try taking a
class, hiring a consultant, or using a more user-friendly OS.
