A. IPX sample configuration

Configuration sample for FLI4L as IPX and IP router:

    #------------------------------------------------------------------------------
    # Optional package: IPX network protocol
    #------------------------------------------------------------------------------
    OPT_IPX='yes'                   # IPX will be enabled via ipx.o module
                                    # and that means: IPX will be generally switched an or off

    IPX_INTERNAL_NET='0x0ABCDEF0'   # number for internal routing.
                                    # You may enter your own values...
                                    # ex.: 0x0CC0815FF

    IPX_NODE='1'                    # means: member of/in the internal network.
                                    # should be left as '1'

    IPX_INTERFACE='eth0'            # Ethernet interface with which IPX shall be
                                    # connected - when only one network adaptor available,
                                    # itīs alwayseth0 (may be checked by using
                                    # "cat /proc/net/ipx_interface)")

    IPX_NETWORK='0x0ABCDEF1'        # IPX network for local network. Leave unchanged

    IPX_FRAME='802.2'               # Should be thenmost used protocol.
                                    # It may be 802.3 in older Netware servers
                                    # or - in combination with IP - sometimes etherII
                                    # If there is already a Novell server existing in the
                                    # network, enter 'AUTO'; otherwise no communication
                                    # is possible.

                                        # see documentation

All of these (above) given values and settings may stand as a good starting base for your first efforts with a dial-in server and may be left as they are. User name, password and telephone number should - of course - be set to your needs ;-)

A specialty will be an exisitng Novell server. Since this server already defined a Network Number and FLI4L shall communicate with this server, you must use the Network Number of the Novell server.

This can be done by reading the values directly from the Novell server or
by asking the Novell Supervisor for the correct values or
you by setting the variable IPX_FRAME (see package IPX) to AUTO.
=> A functioning interface will be created.
After this a Novell server will be fully available - via modem network with activated ipx stack - as if you were connected directly to it in a local network.

You may of course configure FLI4L as a dial-out server. But there is no automatic dialing implemented in the moment because you would have to set up an ipx interface in ipppX. This is not the main problem; but IPX is a very communicative protocol which would lead - without ipx spoofing - to a steady connection.

Packages "ncpfs" and "ipxd" by Volker Lendecke are a good base for your own studies because the programs were taken from these packages. There are other interesting programs in these packages which may be included later on. Additonally "ipppd" offers several IPX parameters which were not used here.

There would also be the possibility to integrate the mars_nwe server - i.e. a Novell Netware clone - but future will show if there is a real need from users for this tool. I am no IPX guru and therefore I beg your pardon in advance if anything was not described correctly. I would like to invite you to give me any kinds of hints and tips.
