Errata

a prompt missing.
ls -l b
should be:
% ls -l b

The setting of prompt is defined in the example as follows:

dru@~:grep prompt ~/.cshrc
if ($?prompt) then
set prompt = "%B%n@%~%b: "

I.e., a space should be inserted between the last ":" and the text user will enter.
However, in the examples in [Hack #2] and [Hack "3], no space is inserted.
A space should be inserted after ":". I.e.,

dru@~:grep prompt ~/.cshrc
should become
dru@~: grep prompt ~/.cshrc

The second line of See Also looks:

man tcsh man idled

These should be separated into two lines.

The next two files work hand in hand and customize the behavior of man mail.
Should be:
The next two files work hand in hand and customize the behavior of mail.

The FILES=1 and FILES=2 in each paragraph should be FILES1 and FILES2 respectively

-s should be -S.
It occurs twice on page 45, once in a listing and once in the paragraph before the listing.

"Even though nbtstat ? indicates..."
should be:
"Even though nbtstat /? indicates..."

daily_clean_tmps:
change /var/log/messages.1.bz2
to
/var/log/messages.0.bz2

.... see (ex)1

The "(ex)1" should be "ex(1)".

The 2 syslogd lines in "Setting Up the Logging Server" should read:

syslogd_enable="YES"
syslogd_flags="-ss"

The 5th line of this output example is:

I'm a node in cyberspace. Who are you?
^
but, the setting example found at the 9th line from
the bottom of previous page 113 is:

... I'm a node in Cyberspace. ...
^

I read:
... in our old friend /etc/login.conf [Hack #30]

but, /etc/login.conf is seen in [Hack #29], not in #30.

"% sshd -l rembackup 10.0.0.1"
should be:

It says that Dheeraj Reddy's ifconfig patch is available from
http://news.gw.com/netbsd.tech.net/%3C20030808072355.GA616%40bharati.sudheeraj.net%3E,
but this URL no longer exists.
I find this patch is available from
http://mail-index.netbsd.org/tech-net/2003/08/08/0001.html

It reads:
ifconfig ${NIC} inet 192.168.1.21 ssid "myhome" authmode "shared"
nwkey 0x123456789a netmask 255.255.255.0

The second line is continued from the first line since "nwkey" is option of ifconfig command. Therefore,
"" is necessary at the end of the first line.

I read:
You can also fine-tune that syntax to unidirectional traffic like so:
# tcpdump -i ed0 src host genisis and dst host server1
That will show only the traffic that was created at genesis and ...
^^^^^^^
This "genesis" should be "genisis"

instead of
# make restart-msp
it should be
# make restart-mspq

Change the last paragraph and listing on p. 213 to:

Set an environment variable to tell ClusterIt where to find the list of
hosts, and set two more to specify ssh as the tool to start remote shells
and terminals. Run this from the tcsh command line or add the commands to
your ~/.cshrc:

setenv CLUSTER ~/.cluster
setenv RCMD_CMD ssh
setenv RLOGIN_CMD ssh

I read:
... you already have the mtree utility [Hack #54]
but, mtree is explained in Hack #22.

/usr/local/etc/apache/httpd-conf

It reads:

it should be:
The Encrypting Disk Partitions (using gbde) section of the FreeBSD Handbook

Both paths in the last paragraph should be changed. it should be:

...renaming /usr/local/etc/rc.d/sudoscriptd.sh.sample to
/usr/local/etc/rc.d/sudoscriptd.sh.

I read:
.... if you're using rsnapshot for backups [Hack #35]
But, rsnapshot was explained in Hack 39, instead of Hack #35.

The script list my three Ethernet cards, rl0, xl0 and rl0

The last line introduces
the URL for ClamAV is
http://clamav.elektrapro.com/
It has changed to:
http://www.clamav.net/

The introduced ftp path:
ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES/5.1-RELEASE/
is now seems to be changed to:
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/5.1/

The introduced URL for Netcat web site
http://www.atstake.com/research/tools/network_utilities
does not exist now. Instead, I think following is the
appropriate URL
http://netcat.sourceforge.net/

fastest-cvsup should be fastest_cvsup
in both the listing and the paragraph that occurs before the listing.

"cd /usr/ports" should be "cd /usr/doc"

Note that the "cd /usr/ports" IS correct under echo "Updating ports index"

Please remove the -l from the "cvs checkout" command on pages 348-349.

The four file names ".ctm-status" in this page should be replaced with ".ctm_status".

SH. NAME
should be:
.SH NAME

The word "psuedoterminal" should be "pseudoterminal".

According to the output of lastcom above this 2nd paragraph,
the user name dlavigne6 should be dlavigne.

should be:
