Are you having issues with the internet or local network? Check out the Network Troubleshooting page for more information on what you can do to make things better or possibly seek help.

[edit] Disclaimer

Please note that Noisebridge does not guarantee or provide a perfect secure experience in the space. Just like anywhere else in the world you're held responsible for your own safety and wellbeing. This also includes content you receive or transmit or provide through any mediums, such as through pen and paper, sound waves or any networks wired or wireless functioning in the space. Noisebridge is a volunteer run and operated space that provides you with infrastructure, which you use at your own risk.

[edit] Free Public Wireless Networks

Noisebridge has two open wifi networks available for your use. In most cases if you connect to the network Noisebridge your laptop/phone/device will have the best luck getting crystal clear wifi and roam between radio channels according to which provides the most reliable and fastest connection.

The wifi and internet provided is for public use. Like any public network, you should regard Noisebridge's as potentially hostile and take appropriate precautions. In order to not give the impression of providing false security, Noisebridge does not run any encrypted wifi networks.

The following networks are active:

  • Noisebridge
    • No password
    • Uplink through Monkeybrains gigabit laser
    • 802.11an 5 gHz only
  • Noisebridge Legacy 2.4 gHz
    • No password
    • Uplink through Monkeybrains gigabit laser
    • 802.11an 2.4 gHz only

[edit] Wired network

There are drops throughout the space. They are labeled with the corresponding number on the patch panel. Please don't destroy them (lol).

[edit] Local Network Address Information

DHCP is offered automatically on the network, if that doesn't work for you here's some more static information...

  • IP Range: 10.20.1.200-10.20.1.254
  • Gateway: 10.20.0.1
  • Subnet: 255.255.254.0 (a "slash" /23)
  • DNS: 10.20.0.1,208.69.43.23,208.69.40.4,8.8.8.8

Dynamic DNS is provided by the router for DHCP clients on 10.20.0.1/23 which also provides name resolution of some local machines.

[edit] Monkeybrains Wireless Link

We have a point-to-point wireless link to Monkeybrains on the roof, it's a gigabit laser, think of fiber without the physical medium of glass. It is wired into the Monkeybrains NEMA box on the roof, and from there into our own NEMA box in which we house a managed switch. From there the cable enters into the space through the ladder chute in the fox lounge and runs to the rack where it enters the switchboard at port 48. Port 48 is a second redundant run that follows the same path from the rack back to our NEMA box for future projects.

[edit] SFBroadband / City of SF / Internet Archive

We have a wireless point-to-point path up to Twin Peaks that connects up to a city-owned and volunteer-run IP transit network. Currently, we're hitting the dish off of the side and have a pretty terrible connection. For now, this network path is mostly only usable as a backup path.

There is a router in our wireless CPE hardware (st01-noisebridge-sfo) that connects up to the Noisebridge network and terminates as 172.30.0.54 on the "Inside / Internal" network. Set your default route via this IP to try the other path.

[edit] I want to help!

Noisebridge is run by volunteers, you're welcome to help but should get to know those helping first before touching/hacking the network gear. Try introducing yourself on the [rack mailing list https://www.noisebridge.net/mailman/listinfo/rack].

[edit] Router

Biketrailer is our humble router. It is an Ubiquiti Edgerouter 5-port box running EdgeOS, a fork of Vyatta (a Linux-based router distribution). While the router does provide PoE, it is non-standard passive Ubiquiti PoE which you should avoid using.

The machines currently provides

  * NAT
  * DHCPD
  * DNS (dnsmasq) - .noise local TLD and recursive proxy

Access is via SSH with keys and a https web interface.

[edit] IPv6

We would like to setup IPv6, some day.

[edit] Machine Rack

The rack sits on the South wall, it's small and up high to discourage people from messing with it or installing things in it. The internet works, please leave the box alone.

[edit] Can I install/setup boxes on Noisebridge's network?

[edit] Short answer

No.

[edit] Long answer

Noisebridge is here to provide infrastructure for creative projects. We're really good at some things. One thing we suck at is administrating boxes setup on our network. They eat power, internet, the attention span of volunteers, and people who set them up generally are bad at communicating later on down the line when something breaks or a machine magically appears.

Noisebridge network infrastructure policy is as such:

  • Critical infrastructure machines (like our access control system): Low power ok!
  • Machines for classes that cannot be hosted on the internet: Low power ok!
  • Personal machines: NO!
  • High power machines: NO!
  • Bitcoin minors: NO!
  • Torrent boxes: NO!
  • Everything else: NO!

If a machine gets setup on the network without first getting an ok from the rack list, it will be unplugged and thrown in the trash. Please don't host your box at Noisebridge. We can't afford it. Thanks for understanding.
