The sudo room network provides internal networking, internet access, wireless service, and some externally accessible devices or services.

Main PoE ethernet switch =

  • HP ProCurve 2910al-480-PoE+ switch
  • username: manager or operator
  • password: Ask juul or someone on the sysadmins list
  • MAC address main switch: a0:b3:cc:ac:e7:c0
  • MAC address backup switch (not turned on): c0:91:34:c4:12:00
  • Port 1 is VLAN 1 untagged, acting as DHCP client, is management VLAN
  • Management possible via HTTP (no SSL) or SSH
  • Port 1 is for management, untagged no VLAN and requests an IP using DHCP (not plugged into anything right now)
  • Port 2 and 3 are for tagged access to VLANs 2 and 3 (public and private)
  • Ports 4 to 24 are for untagged access to VLAN 2 (public)
  • Ports 25 to 48 are for untagged access to VLAN 3 (private)


Internet access comes from LMI. The modem is connected through VDSL copper next to the Omni main electrical panels.

The modem is up in the rack area near saros (a desktop computer running Debian Stretch) which serves as the primary gateway router.

Our public IP is aka


  • Wifi subnet:
    • to legacy static range
    • to DHCP
  • Wired subnet:
    • to unused for now
    • to self assigned static range
    • to DHCP

This list of static IPs may not be complete. Before choosing a static IP, please use ping or nmap to check it first.

By request, we can reserve an IP from the DHCP pool and/or forward ports for you. Please send the MAC address and/or desired ports to
