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computer books are out of date almost before they are printed.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
Page 2
Errata and addenda for the Complete FreeBSD, third edition
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.

________
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.
