Who should read this manual

This is a reference guide with specific detailed information on commands and configuration syntax for the VNetBuild tool. The reference is unlikely to be suitable for newcomers to the tools, except as a means to look up more information on a particular command.

For tutorials and guides to using FireHOL and VNetBuild, please visit the website.

Where to get help

The FireHOL website.

The mailing lists and archives.

The package comes with a complete set of manpages, a README and a brief INSTALL guide.


You can download tar-file releases by visiting the FireHOL website download area.

Unpack and change directory with:

tar xfz firehol-version.tar.gz
cd firehol-version

From version 3.0.0 it is no longer recommended to install firehol by copying files, since a function library is now used, in addition to the scripts.

Options for the configure program can be seen in the INSTALL file and by running:

./configure --help

To build and install taking the default options:

./configure && make && sudo make install

To not have files appear under /usr/local, try something like:

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make install

If your O/S does not usually have a /usr/libexec, you may want to add --libexecdir=/usr/lib to the configure.

Packages are available for most distributions and you can use your distribution's standard commands (e.g. aptitude, yum, etc.) to install these.


Distributions do not always offer the latest version. You can see what the latest release is on the FireHOL website.
