dip.t-dailin.net should be dip.t-dialin.net (not only because the latter is mentioned in example 4.7 but also because that's the correct address that german telekom assign to their clients)

Example 4.10

Judging by the shebang line, the script is supposed to be a Bourne Shell script.

However, neither the lines

level1_sys=alpha beta gamma delta
level2_sys=mercury venus earth mars

nor

foreach system in $level1_sys; do

are valid Bourne Shell (or ksh or bash) syntax.

Note from the Author or Editor:
These are syntax errors. Two lines need double quotes:
level1_sys="alpha beta gamma delta"
level2_sys="mercury venus earth mars"

The other line should read:
for system in $level1_sys; do

2nd paragraph

> The manual page for syslog.conf(5) specifies that these facilities are for local use.

The manual page for syslog.conf(5) does not actually mention the purpose of local[0-7], the one for syslog(3) does, however:

LOG_LOCAL0 Reserved for local use. Similarly for LOG_LOCAL1 through LOG_LOCAL7.

> You, the administrator, may define these seven facilities [..]

Unless local0 has a special meaning there are eigth of them.

Note from the Author or Editor:
This is correct. There are 8 facilities LOCAL0 through LOCAL7 and they are documented in the syslog(3) man page.
