Errata

This page lists the errors in the book and the CD-ROM. I apologize that a few errors were not caught despite many passes through the text and programs and scripts were uploaded from tested code.

Book errors

Minor typo on page 442

In the second line, the wrong Appendix is listed. It should be E.1.

Omitted line on page 455

A line was omitted from the book, as described here. (Note that the CD-ROM is correct.) In the fifth line from the bottom of page 455, that reads

     $IPT -A FORWARD -p udp --dport $i -j DROPl

insert the following above it.

     $IPT -A OUTPUT -p udp --dport $i -j DROPl

Typos on page 457

On the third and sixteenth lines, each of which start

     $IPT -A OUTPUT -i

please change -i to -o.

CD-ROM errors

issue and issue.net files

On the CD-ROM, under the book directory, these files have a typo. To correct, shift click on the links issue and issue.net or edit your copy from the CD-ROM and change the word extend to extent.

These files' updated cryptographic signature files are issue.sig and issue.net.sig. Shift-clicking on the links will download the files.

To check the signature for, say, issue, after downloading issue and issue.sig, issue the command

     gpg --verify issue.sig issue

The GNU Privacy Guard program should respond with

     gpg: Signature made Fri Jan 03 16:58:16 2003 EST using DSA key ID E3A1C540
     gpg: Good signature from "Bob Toxen (New standard email address for book) "

It is important for the DSA key ID to be

     E3A1C540

and the text to include

      Good signature from "Bob Toxen (New standard email address for book) <book@verysecurelinux.com>"

The date may vary.

rc.fwsoho and rc.fwdmz files

On the CD-ROM, under the book/iptables directory, these files have minor errors. Thanks to Erik Terwiel for pointing this out. To correct, shift click on the links rc.fwsoho and rc.fwdmz.

These files' updated cryptographic signatures files are rc.fwsoho.sig. and rc.fwdmz.sig. Shift-clicking on these links will download the files.
