Absolute OpenBSD: Unix for the Practical Paranoid

At various points, we'll refer to the OpenBSD system source code. I recommend installing it immediately, as it will save you minor annoyance later.

The source code is available on one of the CD-ROMs in the set. If you installed OpenBSD via FTP, you can also download the source code via FTP. You can find the source code on the same FTP server you installed OpenBSD from, in the release directory, as a file called "src.tar.gz." Just extract this directory under /usr/src.

# cd /usr/src # tar -xzvpf srcsys.tar.gz ...
