1.2 Requirements

To install the FCM kernel modules, they must first be compiled. Because of differences in compiled kernels due to selected options, it is important that the modules be compiled with the correct kernel source. The modules were developed for kernel version 2.4.18, but may work on other 2.4 kernels, however incompatibilities may occur.

1.2.1 Kernel Requirements

Before the Router module can be compiled, the following options must be compiled into the kernel:

• QOS and/or fair queueing

Before the Receiver module can be compiled, the following options must be compiled into the kernel:

• Network packet filtering (replaces ipchains)
• Connections tracking (required for masq/NAT)

If you are unsure how to add these options, the next section will explain where to find them.

1.2.2 Utility Requirements

Use of the Router module requires the `tc' (Traffic Control) utility. In the Debian 3.0 distribution, this can be found in the iproute package. To install this, the following command should be run as root: apt-get install iproute

The Receiver module requires no utilities other than the standard module loading tools.

The logger requires no kernel options or extra utilities. It does however require the Router to be installed and working.
