    Why use FBB with Linux ?

    LINUX is a true multitasking system where many applications may run
    concurently. When Linux (and other UNIX systems) has finished booting
    it is possible to run one ore more applications running concurently (NODE,
    BBS, CLUSTER, TCPIP, etc...) on the same CPU and above all very fast and
    secure.

    Another good thing for linux is that the AX25 is included in the kernel,
    and then you need no TNC, no BPQ or other. You only need hardware. (think
    of a DOS including Netrom, Rose, AX25, TCPIP and other software....)

    Info on AF_AX25, AF_NETROM ans AF_ROSE.

    Standard kernel AF_AX25, AF_NETROM and AF_ROSE sockets
    AX.25, NET/ROM and ROSE protocol are built into the Linux kernel.

    I recommend to use these interfaces, because it will give you
    more flexibility to build a system with many futures..

    This choice may be little difficult to set up,
    because the functions is depended of lots of things.. eg:
     - Linux kernel version
     - ax25-utils version
     - z8530drv version
     - net-tools version
     ... and more

    If you desire to use this/these interfaces,
    i strongly recommend to read at least AX25-HOWTO!

    The AX25-HOWTO located at:
    http://sunsite.unc.edu/mdw/HOWTO/AX25-HOWTO.html

    More HOWTO´s located at:
    http://sunsite.unc.edu/mdw/HOWTO/HOWTO-INDEX-3.html

    The Linux Documentation Project Homepage is located at

    Install AF_AX25, AF_NETROM and AF_ROSE.

    How to set up Linux kernel AF_AX25, AF_NETROM, AF_ROSE socket.

    These examples are for Linux kernel 2.0.27 patched with ax25-module-7.

    First, get these files (or newer files).
     Linux kernel 2.0.27
      available @ ftp://ftp.funet.fi/pub/Linux/PEOPLE/Linus/

     ax25-utils-2.0.12c.tar.gz
     ax25-module-7.tar.gz
     ax25-utils-module-7.tar.gz
      available @ http://www.cs.nott.ac.uk/~jsn/

    Unpack kernel 2.0.27 in ´/usr/src´ with ´tar zxvf linux-2.0.27.tar.gz´
    this will unpack kernel 2.0.27 to a directory called ´linux´ ,
    beware if you already have a directory named ´linux´ in ´/usr/src´.

    Tip:
    I rename my kernel source directory to kernel version with ´mv linux linux-2.0.27´
    then i do a symbolic link to this directory with ´ln -s linux-2.0.27 linux´

    Before i install a new kernel, i remove the symbolic link (eg: rm linux),
    this allows me to have more kernel sources installed at same time.. :-

    Okay, now it´s time to compile the ´ax25-utils-2.0.12c.tar.gz´ ,
    unpack this file in ´/usr/src´ with ´tar zxvf ax25-utils-2.0.12c.tar.gz´.

    I can´t compile ´ax25-utils-2.0.12c.tar.gz´ after patching the kernel
    with ´ax25-module-7.tar.gz´... :-/

    Read the ´INSTALL´ file how to compile, and install this package.

    Now it´s time to patch the kernel with ´ax25-module-7.tar.gz´,
    unpack this file in ´/usr/src´ with ´tar zxvf ax25-module-7.tar.gz´,
    then type ´cat ax25-module-7/ax25-2.0.27-2.1.19.diff | patch -p0´

    Okay, do ´cd linux´ now, read the file README now, to know how to set up the kernel!

    Okay, now it´s time to run ´make config´ , be sure that you enable
    - Amateur Radio AX.25 Level 2 (CONFIG_AX25)
    - Amateur Radio NET/ROM (CONFIG_NETROM)

    If you want to use ROSE, enable this..
    - Amateur Radio X.25 PLP (Rose) (CONFIG_ROSE)

    You can make these as loadable modules, or to be compiled into the kernel.

    After you finished with ´make config´ , then type ´make dep; make clean; make zImage´
    to compile the new kernel with AX.25 and NET/ROM support (and ROSE if defined).

    After compilation, install the new kernel, as in the /usr/src/linux/README file.

    Okay, you should have rebooted and started up the new kernel now..

    Now it´s time to compile ´ax25-utils-module-7.tar.gz´ ,
    unpack this file in ´/usr/src´ with ´tar zxvf ax25-utils-module-7.tar.gz´,
    do ´cd ax25-utils.module-7´ and read the INSTALL file how to compile and install!

    If all steps has gone without problem, you are now ready to set up your Linux system
    to work with kernel AX.25, NET/ROM (and ROSE if defined), CONGRATULATIONS!

    Now you should go to ´/usr/src/ax25-utils-2.0.12c´ and read the README file,
    to find out what files you should need to change for suite you.

    All configuration files are in ´/etc/ax25´.

    Tip:
     Read the AX25-HOWTO @ http://sunsite.unc.edu/mdw/HOWTO/AX25-HOWTO.html

    Config AF_AX25, AF_NETROM and AF_ROSE for KISS TNC and SCC card.

    How to setup LinFBB to use kernel AF_AX25, AF_NETROM and AF_ROSE sockets.

    Here is a example with LinFBB and one KISS TNC at COM1, 8 channels.
