Linux Routers was my first book, and as such, I placed considerable strain on my editors, copyeditors, and the typesetter who cleaned up what was also my first major project using the LaTeX text-formatting system. In addition, the book was initially written for the 2.0 version of the kernel. As time passed, I decided to include code/documentation for both 2.0 and 2.2 kernel users, and then shortly before publishing, Prentice Hall and I agreed that the examples were clearer when they referenced only one kernel version, so we opted for version 2.2. Unfortunately, a few kernel 2.0 ``isms'' snuck into the book, along with a few other typos and problems.
As I find and am made aware of these errata, I will post them here. Please notify me at tony@mancill.com if this list is inaccurate or incomplete.
