Errata

Incorrect punctuation: period inside the parentheses:

"dynamic content (like cgi scripts.)"

Period should be outside the parentheses in this instance, much like the example on the same page, last paragraph, first sentence.

echo -n `echo $x|cut -f 2- -d '-'`;echo -ne '00'
should read:
echo -n `echo $x|cut -f 2 -d '-'`;echo -ne '00'

Incorrect punctuation: period inside the parentheses:

"of this process (you can, for example, cd /proc/3852/cwd to land in the directory from which process ID 3852 was run.)"

Period should be outside the parentheses in this instance, much like the example on the same page, 2nd text paragraph, last sentence.

"The exe link points to full path to the binary"
should be:
"The exe link points to the full path to the binary"

"processes" is possessive, not plural, and should be process's or process', depending on your favoured style.

"and back grounded processes"
should be:
"and backgrounded processes"

Incorrect punctuation: period inside the parentheses:

"Select your drivers carefully (hitting Y for built-in drivers, and M for loadable modules.)"

Period should be outside the parentheses in this instance, much like the examples in the two preceding sentences.

Incorrect punctuation: period inside the parentheses:

"the High Memory Support setting (a.k.a. the CONFIG_NOHIGHMEM define.)"

Period should be outside the parentheses in this instance, much like the example on the same page, first paragraph, last sentence. This page, in the 3rd last paragraph, last sentence, contains one of the few examples in the book where the period belongs in the parentheses (and is correct).

Incorrect punctuation: period inside the parentheses:

"total system RAM at boot.)"

Period should be outside the parentheses in this instance, much like the example on the same page (2nd last paragraph, 2nd sentence) does with the comma.

First sentence completely missing its period: after "Java application)"

In "The special CVS file notify", the word "notify" should be in italics, much as the word "users" is in the same paragraph, third sentence. In both cases a literal filename is being referred to.

Spurious "<code>" at the end of the example. It doesn't make any sense there, and it is not in bold like the preceding text, it is most likely a text/formatting typo of some sort.

Incorrect punctuation: period inside the parentheses:

"is another common choice.)"
and
"quick way to do that.)"

Period should be outside the parentheses in both instances, much like the example on the same page, 2nd paragraph, 1st sentence.

"contained with in it"
should be:
"contained within it"

Incorrect punctuation: period inside the parentheses:

"logins with pserver.)"

Period should be outside the parentheses in this instance, much like the example on the following page, middle of 2nd paragraph.

The whole sentence makes no sense. "tar" is not a "design decision" in "ssh". ssh knows nothing about tar. Perhaps saying instead "the ability of ssh to use standard input/output, like with tar," is a brilliant design decision would make more sense. It needs a whole new rejigging.

Incorrect punctuation: period inside the parentheses:

"and an ssh session.)"

Period should be outside the parentheses in this instance, much like the example in the immediately preceding sentence.

"much of a network admins' time"

You can't have a singular subject, as dictated by the word "a", and a plural possessive use of the apostrophe. It should be:

"much of a network admin's time"
or
"much of network admins' time"

rp_filter isn't really a "free firewall rule" (i.e., something in iptables), it's a kernel network stack setting. Whilst certainly useful in a "firewall" scenario, its usefulness certainly isn't limited to one.

"the console with iptables!) If you"
Needs punctuation outside of the parenthesis, either by moving the exclamation outside, or, better, adding a period and leaving the exclamation where it is. (3/03 printing)

Line-continuation backslash is missing from this line (after "fa:ca:de"). It is present on the two preceding lines.

I think I have found the following typo; instead of:

# ip tunnel add mytun mode ipip remote 240.101.83.2
local 251.4.92.217 ttl 255
# ifconfig tunl0 10.42.2.1

the author intended to write "mytun" instead of "tunl0", namely:

# ip tunnel add mytun mode ipip remote 240.101.83.2
local 251.4.92.217 ttl 255
# ifconfig mytun 10.42.2.1

"...remote clients appear to exist on the network services, or more generally, to connect to any two private networks together..."

This sentence has faulty wording, and makes little sense as-is. It makes sense if you remove the word "services" and change "to connect to" to just "to connect".

First word of sentence ("this") is not capitalized.

Incorrect punctuation: period inside the parentheses:

"stop displaying idle processes.)"

Period should be outside the parentheses in this instance, much like the example on the next page (1st paragraph, last sentence).

Incorrect punctuation: period inside the parentheses:

"any signal you like.)"

Period should be outside the parentheses in this instance, much like the example in the subsequent sentence.

"note the ' in the google query"

The glyph used for the apostrophe is a opening single quote: i.e., it's pointing the wrong way. It's referring to the apostrophe in the word O'Reilly, which would require a "closing" single quote, or a "directionless" glyph.

([3/03*] version of the book)

"The script can continue to watch to watch when ..."

Strike the duplicated "to watch".

Incorrect punctuation: period inside the parentheses:

"...on it for security and performance reasons.)"

([3/03*] version of the book)

"overtime" should be "over time"

"Now you can watch activity on all of your hosts simultaneously with a command, as:"

Awkward wording. It works much better if you change the comma to the word "such". (The previous example uses the wording "like this", which works quite well.) You could also add the word "such" after the comma, but the wording ("with a command") remains odd (of course you'll use "a command", what else would you do?). Perhaps "command" should be qualified with "simple" or "single"?

"installed on each homer, bart"
grammatically incorrect, possibly try:
"installed on each of homer, bart" (3/03 printing)

"it but becomes"
should be
"but it becomes" (3/03 printing)

"matches multiple view statement's match-clients substatements"
should be:
"matches multiple view statements' match-clients substatements"
as statements is plural possessive (as per "multiple"). (3/03 printing)

"]One suggested method"
Should have spurious square bracket removed. (3/03 printing)

"and 9, very carefully.)"
should have the period outside the parenthesis. (3/03 printing)

"Start MySQL on each slave... Finally, fire up MySQL on each slave"
is redundant, both sentences say the same thing. Possibly just delete the first sentence since the second and third sentence repeat the same ideas. (3/03 printing)

Just a suggestion - it seems like all of my mysql dumps insert backticks all over the place, including the table name, which makes this hack not work. I suggest making the following changes for anyone else having the problem:

Remove the "" from the two spots in extract-table script, so this:

#!/usr/bin/perl -wn
BEGIN { $table = shift @ARGV }
print if /^create table $table/io .. /^create table (?!$table)/io;

becomes this:

#!/usr/bin/perl -wn
BEGIN { $table = shift @ARGV }
print if /^create table $table/io .. /^create table (?!$table)/io;

And when you go to run the command instead of:

zcat /var/spool//mysqldump/randomdb.20020901.gz | extract-table Users > ~/Users.dump

Do this:

zcat /var/spool//mysqldump/randomdb.20020901.gz | extract-table "`Users`" > ~/Users.dump

"takes the form database user password"
needs some type of punctuation or formatting to indicate this is a list. Possibly constant width italic for the 3-tuple (or commas between each item) and a colon after "form". (3/03 printing)

"Linux Help.Net"
should have no space in the URL. (3/03 printing)

"snippet from a Apache"
should be
"snippet from an Apache" (3/03 printing)

"log the information to it's access_log."
should be:
"log the information to its access_log."
"its" is possessive. (3/03 printing)

"delivered by a script the takes"
should be:
"delivered by a script that takes" (3/03 printing)

"it returns predictable contend (say, the default view of the first page of an article.)"
should be:
"it returns predictable content (say, the default view of the first page of an article)."
Two changes: "contend" to "content", and move the period outside the parenthesis. (3/03 printing)

"gateway for 12.34.56.78)."
Period should be inside the parenthesis. (3/03 printing)

the index entry for 'rcg' is mistakenly labelled 'rgc'
