The CorbettDigital GigaPOP

The CorbettDigital home network has grown to be vastly overcomplicated and has several features rarely found in ordinary home networks, including multiple VLANs, site-to-site VPNs, multiple firewall layers, BGP routing, IPv6, and single-sign-on services.


Boxes are end hosts; diamonds are routers; circles are switches

Function Listing, by machine

  • Servers
    • unimatrix -- directory services
    • wintermute -- web/db/backup server
    • kd8gbl -- ham radio node
    • visi-gw -- internet gateway
    • nas01 -- file server
    • wifi-gw -- wireless access point
    • icebox -- Netscreen 5GT-ADSL firewall
    • deadend -- Netscreen 5GT firewall
    • UPS -- APC SmartUPS 1400RM (3U)
    • miranda -- mail server (external, VM 'in the cloud')
  • Desktops
  • Network gear
    • LANrover -- management console terminal server

The gigabit subnet runs over an Netgear 8-port switch and uses 7k byte jumbo frames. Most services are provided on both subnets using IPv6 where available. Most machines use LDAP direcory services and Kerberos authentication. Shared home directories are provided via NFS. Servers are remotely managable (mostly) via the LANrover.
