    Hello,

    its always a good practice to have servers set with fixed static IP
    addresses, and this includes printers and other common resources that
    are shared across the network regardless of what type of realm is being
    used (nis, nt domain, or netware), if for some reason you want the
    servers, printers and whatever obtain their IP address through DHCP, you
    can still do that by configuring your dhcp deamon (service) to reserve
    particular IP addresses for given mac address, it is quiet simple and
    all you have to do is just check the examples in the manuals and use
    them.

    now in every network it is good to have only 1 dhcp server, if you have
    2 and each having a different configuration, you start running into
    troubles and the network client pcs will start to cough and get sick,
    and that wouldnt be nice especially during the comming xmass holidays.

    a simple clean setup in this case would be as the following:

    1- do not run DNS or dhcp on your novell (ofcourse you will have to run
    the basic DNS so that the directory would work)
    2- do not use your router as DHCP server, the reason for that is if it
    goes down for some reason well so will all the DHCP dependent pcs in the
    network.

    as for the installation figure well,

    NOVELL SEVER
    - DIRECTORY services
    - file and printing services
    - misc services (possibly intranet or whatever you may have there)
    - DNS service, since you have a novell system in your network, you are
    obliged to use the DNS from your novell system, (if you are not
    performing any sort of directory based fine grained network services,
    you do not need to use the DHCP service there, just use the one on the
    linux system)

    SuSE 9.1 server
    - Firebird DBMS (dunno why you want to use that one, there are many
    other options, mysql/postgress, etc)
    - DHCPd service (configure it to assign static IP address to the
    machines that require static ip addresses (for whatever reason)

    Router
    - do not run any services on it, just keep it simple and let it route
    and provide network statistics and perform the network security
    (firewall if it has that feature)

    Network printer
    - configure it with a static ip or to get a static ip from DHCP

    network PC clients
    - configure to get IP, DNS, gateway configurations

    DHCP service should provide the following

    IP ADDRESS POOL
    NETWORK MASK
    NETWORK GATEWAY
    POSSIBLY WINS SERVICE (pointing to novell)
    DNS (pointing to NOVELL)

    configure the DNS on your novell to point to your
    network services whereever they may be including printers.

    i might have mentioned half the things i wanted to say as i am writting
    this in between things :)

    regards
