Windows networking

Windows networking involves the following subsystems:

  1. DHCP:
    Supplies an IP address to the machine when it boots. The mapping of MAC address (ethernet hardware identification) and IP address is defined in the /etc/dhcpd.conf file. Machines not defined in this file get assigned a dynamic address in the range and These dynamic assignments are then refected in /var/state/dhcp/dhcp.leases, from where they can be moved to /etc/dhcpd.conf (attention, different format).

    N.B. DNS has not access to these files, it must be configured separately to use the same names!

  2. The Samba file server, authenticates the user, handles domain login, supplies time and exports the user's home directory to the client workstation where he is logged on to.
