          How do I configure Dynamic Host Configuration Protocol (DHCP) on
          SCO OpenServer 5 and UnixWare7?

          Follow these steps:

          1. Decide on which IP addresses you want to be allocated to DHCP
          clients. These IP addresses should be unused by any other machines.

          2. Run SCOadmin Address Allocation Manager.

          3. Choose:

              View -> Pool Definition

          4. Configure a pool <poolname> with the IP addresses you wish to
          allocate. (A pool is the same as a scope, in Microsoft terminology.)

          5. Start the AAS server:

              Server -> Start Server

          6. Run SCOadmin DHCP Manager.

          7. Choose:

              View -> Subnets

          8. Choose:

              Entry -> Add

          Enter the subnet and mask addresses, for example, for a class C
          address 150.126.20.0:

              subnet: 150.126.20.0

              mask: 255.255.255.0

              <poolname>

              lease period (for example, 1 day)

              Generic

                  Examples to set would be:

                  3 - router (The IP address of your gateway)
                  6 - dns_servers (The IP addresses of your nameservers)
                  15 - domain (The FQDN for your server)

          9. Check /etc/inetd.conf. It should contain the uncommented line:

              bootps dgram/i udp wait root /etc/dhcpd dhcpd

              If necessary, restart TCP/IP, the inetd daemon or reboot for that
              change to take effect, if required.

          10. Configure your DHCP clients.  

          For example, to set up a UnixWare 7.1.x system as a DHCP client:

              a. Run SCOadmin Network Configuration Manager.

              b. Add a LAN adapter, or choose Modify Protocol if the LAN
                 adapter is already configured.

              c. In the Internet Protocol Configuration window, select
                 DHCP Client, and click OK.

          11. Reboot your DHCP clients. They should pick up their IP
          addresses from the pool you defined.

          Note: The IP addresses used in this article are for example
          purposes only.

          Should there be a timeout delay in obtaining DHCP information check
          to see if the DHCP server is using DNS in it's /etc/resolv.conf file
          and is able to access the nameservers configured.

          It is recommended to use the GUI version of "scoadmin dhcp" to 
          configure the options as trying to add Vendor and User classes within
          "scoadmin dhcp" from the command prompt may cause "scoadmin" to 
          crash.

          pages that don't exist."

          UnixWare 7."
