The following steps assume that your m0n0wall root file system will
be built in $MWROOT, so create a directory to hold the root
file system and set MWROOT to point to it.
cd $MWROOT mkdir bin cf conf.default dev etc ftmp mnt modules proc root sbin tmp usr var mkdir etc/inc ln -s /cf/conf conf cd usr mkdir bin lib libexec local sbin share cd local mkdir bin captiveportal lib sbin www ln -s /var/run/htpasswd www/.htpasswd
/cf is where the Compact Flash card (or
the hard disk, or the floppy disk) is mounted later on
/conf.default contains the factory
default config.xml
/conf (or /cf/conf
effectively due to the symlink) contains the current
config.xml
/ftmp is used to mount a temporary memory
file system during a firmware upgrade through the webGUI
/etc/inc contains PHP include files that
are used by both the boot scripts and the webGUI
/usr/local/www contains the webGUI
pages
/usr/local/captiveportal is the web root
directory for the HTTP server process to which HTTP connections are
redirected if the captive portal is on and the user hasn't
authenticated yet
the symbolic link for .htpasswd is required as the boot
scripts will write the webGUI user/password to
/var/run/htpasswd
To facilitate this, a list of binaries that need to be copied is provided along with a simple perl script to copy them over (taken from the miniBSD tutorial). Download the script from http://m0n0.ch/wall/downloads/freebsd-4.11/mkmini.pl and the list of binaries from http://m0n0.ch/wall/downloads/freebsd-4.11/m0n0wall.files.
perl mkmini.pl m0n0wall.files / $MWROOT
Most of the base contents of /etc aren't very interesting, so they're available as a tarball to save the time it would take to put them together from FreeBSD sources. Download from http://m0n0.ch/wall/downloads/freebsd-4.11/etc.tgz and extract as follows:
tar -xzf etc.tgz -C $MWROOT
/etc/version holds the version number of
the image. Create with e.g.
echo "1.21" > $MWROOT/etc/version
/etc/version.buildtime is displayed in the
webGUI. Create as follows:
date > $MWROOT/etc/version.buildtime
/etc/platform identifies the platform for
which the image is built and is very important, as the PHP scripts use
it to determine e.g. how the configuration is to be stored or which
options should be available in the webGUI. Possible values are:
net45xx
net48xx
wrap
generic-pc
generic-pc-cdrom
echo "net45xx" > $MWROOT/etc/platform
FreeBSD 4.x doesn't have devfs yet, so we need to add a few essential device files. You could copy the contents of /dev on your FreeBSD box or use MAKEDEV; however, that would result in many device files that aren't necessary. A tarball of all the devices that are typically needed in m0n0wall is provided at http://m0n0.ch/wall/downloads/freebsd-4.11/dev.tgz. Extract as follows:
tar -xzf dev.tgz -C $MWROOT
Download the latest default config.xml from
http://m0n0.ch/wall/downloads/config.xml
and put it in
$MWROOT/conf.default/config.xml.
FreeBSD keeps time zone information files in
/usr/share/zoneinfo. In order to save space,
m0n0wall uses a stripped down version of the contents of that directory
and keeps them in a tarball. Download zoneinfo.tgz from http://m0n0.ch/wall/downloads/freebsd-4.11/zoneinfo.tgz
and place it in
$MWROOT/usr/share/zoneinfo.tgz.
