DHCP / Proxy

Via Dynamic Host Configuration Protocol (DHCP), computers can be automatically configured for existing networks. This means that IP-address, network mast, gateway, and DNS server are steered through the DHCP server. Clients merely need to allow for the automatic access of IP-addresses.

Additional functionalities:

  • automatical configuration of a web-proxy via WPAD
  • booting of live systems via PXE
  • administration of Sun Ray Clients
