synopsis

I've (xopr) started this network information page mainly because no-one knows the current setup by heart, and I was preparing for Congress everywhere without breaking people's precious downloads..

current setup

PoEswitch

Probably connected to fuse group A.

Port 1: Event Accesspoint 2: VoIP 3: VoIP 4 5 6 7 8

Note that VLAN7 is used for xopr's Mesh node which should provide spacenet near bbq.

hACKswitch

Connected to fuse group A.

router

The Linksys router is connected to both fuse groups A and B (via two adapters and a schottky diode splitter).

It is running stock firmware to ensure basic internet connectivity in the space. Config is kept KISS for this reason.

VLAN NC 200u 200u 200u 200u
Port NC 1 2 3 4

Spacenet AP

Configured all ports as a switch. DHCP disabled. At this point only used for spacenet and can be used for experiments. Runs OpenWRT.

VLAN 200u 200u 200u 200u 200u
Port WAN 1 2 3 4

notes

  • Da Syntax and xopr redid all the cabling on February 13th 2016. All static cables are labeled on both sides, tucked away thoroughly, trimmed, and plugged in documented ports. Please keep the label on (and updated) at all times. You can find the label-tywraps in the network-connector box in the stACKspace.
  • Adnub redid the whole network topology on January 29th 2022. If you are uncertain about something, ask him first.
    Want to connect something? No problem; just pick any free (blue) port.
    Want a permanent connection? Should be no problem; make sure everyone is informed (via the discussion page, for example, so we can reach consensus).
