          Errata and addenda for the Complete FreeBSD, third edition




                         Last revision: 2 August 1999

The trouble with books is that you can't update them the way you can a web page
or any other online documentation.   The  result  is  that  most  leading  edge
computer  books are out of date almost before they are printed.  Unfortunately,
``The Complete FreeBSD'', published by Walnut  Creek,  is  no  exception.   In-
evitably, a number of bugs and changes have surfaced.

The  following  is  a list of modifications which go beyond simple typos.  They
relate to the third edition, formatted  on  17  May  1999.   You'll  find  this
information  on  page  iv  (the  page  before  the  beginning  of  the Table of
Contents).  See the end of this document for instructions on how  to  find  the
errata for an older version.

You can get the current document in four forms:

o A     PostScript     version,     suitable     for     printing    out,    at
  ftp://ftp.lemis.com/pub/cfbsd/errata-3.ps. See page 302 of the third  edition
  to  find  out  how  to print out PostScript.  If at all possible, please take
  this document: it's closest to the original text.

  Be careful selecting this file with a web browser: it is often impossible  to
  reload the document, and you may see a previously cached version.

o An enhanced ASCII version at ftp://ftp.lemis.com/pub/cfbsd/errata-3.txt. When
  viewed with more or less,  this  version  will  show  some  highlighting  and
  underlining.  It's not suitable for direct viewing.

o An  ASCII-only  version at ftp://ftp.lemis.com/pub/cfbsd/errata-3.ascii. This
  version is posted every week to the  FreeBSD-questions  mailing  list.   Only
  take  this version if you have real problems with PostScript: I can't be sure
  that the lack of different fonts won't confuse the meaning.

o A web version at http://www.lemis.com/errata-3.html.

All these modifications have been applied to the ongoing  source  text  of  the
book, so if you buy a later edition, they will be in it as well.  If you find a

_______

The instructions on page ii (opposite the title  page)  tell  you  to  look  at
ftp://ftp.lemis.com/pub/cfbsd/errata-2  for  the  errata  list.   That's wrong.
Look at this list.

Pages 190 and 191
_________________

The description is not very clear about which text appears  when  booting  from
floppy  for  initial  install,  and  which  appears when booting normally.  The
procedure is very similar, but there are some differences.  Add  the  following
text after the heading Boot messages:

You'll  boot  your system in at least two different ways: initially you'll boot
from floppy or CD-ROM in order to install the system.  Later, after the  system
is  installed,  you'll boot from hard disk.  The procedure is almost identical,
so we'll look at both versions in the following examples.

Replace the text from the middle of page 191 with:

If you're booting from 1.44 MB floppies, you will then see:

Please insert MFS root floppy and press enter:

When you insert the MFS root floppy and press  Enter,  you  see  more  twirling
batons, then the UserConfig screen appears.

UserConfig: Modifying the boot configuration
____________________________________________

After  the  kernel has been loaded, the following screen will appear if you are
installing the system, or if you have requested it with the -c  option  to  the
boot loader:

The  bottom  two lines on this page should be in bold constant font, indicating
that this is input for your /etc/rc.config file

nfs_client_enable="YES"       # This host is an NFS client (or NO).
nfs_server_enable="YES"       # This host is an NFS server (or NO).


Page 265
________

The example on the second half of the page refers to the old SCSI driver.   The
scsi  program  is  no  longer  available  in  FreeBSD  3.x.   Instead,  use the
camcontrol program.  Replace the text with:.

Modern disks make provisions for recovering from such errors by  allocating  an
alternate sector for the data.  IDE drives do this automatically, but with SCSI
drives you have the option of enabling or disabling reallocation.   Usually  it
is  turned on when you buy them, but occasionally it is not.  When installing a
new disk, you should check that the parameters  ARRE  (Auto  Read  Reallocation
Enable)  and AWRE (Auto Write Reallocation Enable) are turned on.  For example,
to check and set the values for disk da1, you would enter:

# camcontrol modepage da1 -m 1 -e -P 3
# scsi -f /dev/rda1c -m 1 -e -P 3

This command will start up your favourite editor (either the one  specified  in
the EDITOR environment variable, or vi by default) with the following data:

AWRE (Auto Write Reallocation Enbld):  0
ARRE (Auto Read Reallocation Enbld):  1
TB (Transfer Block):  0
RC (Read Continuous):  0
EER (Enable Early Recovery):  0
PER (Post Error):  0
DTE (Disable Transfer on Error):  0
DCR (Disable Correction):  0
Read Retry Count:  16
Correction Span:  41
Head Offset Count:  0
Data Strobe Offset Count:  0
Write Retry Count:  16
Recovery Time Limit:  0

The  values  for  AWRE  and  ARRE should both be 1.  If they aren't, as in this
case, where AWRE is 0, change the data with the editor, save it, and exit.  The
camcontrol  program will write the data back to the disk and enable the option.


                                                                         Page 3

________

The description of the config refers to the SCSI drive sd0.  This  is  the  old
name; in FreeBSD version 3, SCSI drives are called da, so this reference should
be da0.

Thanks  to  Francisco  Reyes  <francisco@natserv.com>  for  pointing  out  this
problem.

Page 362
________

Replace the text at the top of the page with:

Next, change to the build directory and build the kernel:

# cd ../../compile/FREEBIE
# make depend
# make

   The  make  depend  is needed even if the directory has just been created:
   apart from creating dependency information, it also  creates  some  files
   needed for the build.
Thanks to Mark Ovens <marcov@globalnet.co.uk> for drawing this to my attention,
and   to   Francisco   Reyes   <francisco@natserv.com>   and   Bill    Fumerola
<billf@jade.chc-chimes.com>  for pointing out that it still wasn't fixed in the
third edition.

Page 409
________

The information on setting the default routers specified the wrong end  of  the
PPP  links  in  some  places.  It should always be the ``far'' end of the link.
Replace the second example on page 409, and the text following  it,  with  this
text:

defaultrouter="139.130.136.129"    # Set to default gateway (or NO).
static_routes=""              # Set to static route list (or leave empty).
gateway_enable="YES"               # Set to YES if this host will be a gateway.

This  is the normal way to set the default route on a point-to-point interface.
In fact, for PPP you don't  need  to  specify  the  default  address:  the  PPP
packages will set it for you when the link comes up.  This makes it possible to

Page 4






                     Errata and addenda for the Complete FreeBSD, third edition


set default routes when you're forced to use dynamic IP  addresses,  where  you
don't know the address at this point.  We'll see how PPP does this on page 446.

In the first example on page 410, the sixth example on page 412 and the  second
example on page 413, replace the defaultrouter definition with:


defaultrouter="139.130.237.65"          # Set to default gateway (or NO).


Thanks to Andreas Longwitz <longwitz@Incore.de> for pointing out this error.

Getting errata for older editions of the book
_____________________________________________

There have been a total of five different versions of ``The Complete FreeBSD''.
The most accurate way to distinguish them is by the format date,  which  you'll
find  at  the  bottom of page iv (the page before the beginning of the Table of
Contents) in all versions of the book.

1. The first was titled ``Installing and running FreeBSD'', and  was  formatted
  on 24 February 1996.  No errata list exists for this book.

2. For  the first edition (19 July 1996), get ftp://ftp.lemis.com/pub/cfbsd/er-
  rata-1.   This   same   file   is   also   available   via   the   web   link
  http://www.lemis.com/errata-1. I am no longer updating this errata list.

3. The  list  for  the  second  edition (16 December 1997) is available in four
  forms:

  o A    PostScript    version,    suitable    for     printing     out,     at
    ftp://ftp.lemis.com/pub/cfbsd/errata-2.ps.  See  page  222  of  the  second
    edition to find out how to print  out  PostScript.   If  at  all  possible,
    please take this document: it's closest to the original text.

    Be  careful  selecting this file with a web browser: it is often impossible
    to reload the document, and you may see a previously cached version.

  o An enhanced ASCII  version  at  ftp://ftp.lemis.com/pub/cfbsd/errata-2.txt.
    When viewed with more or less, this version will show some highlighting and
    underlining.  It's not suitable for direct viewing.

  o An ASCII-only version at ftp://ftp.lemis.com/pub/cfbsd/errata-2.ascii. This
    version  is  posted every week to the FreeBSD-questions mailing list.  Only

                                                                         Page 5






Getting errata for older editions of the book


    take this version if you have real problems with  PostScript:  I  can't  be
    sure that the lack of different fonts won't confuse the meaning.

  o A web version at http://www.lemis.com/errata-2.html.

4. The  revised  second edition was formatted on 11 February 1999.  As the name
  suggests, it's not a complete new edition: in fact, only three  chapters  are
  different:

  o The chapter ``Setting up X11'' has been brought up to date.

  o Appendix  D (``Contents of the Ports Collection'') has been replaced by two
    appendixes, ``Errata and Addenda'' (the errata list up to date at the time)
    and  ``FreeBSD  3.0'',  which describes the differences between FreeBSD 2.x
    and FreeBSD 3.x.

  There is no separate errata list for this book.  Refer to the second  edition
  errata list.

5. The  current,  third edition, formatted on 17 May 1999.  This is the correct
  list for this edition.
