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.
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:
- No password
- Uplink through Monkeybrains gigabit laser
- 802.11an 5 gHz only
- No password
- Uplink through Monkeybrains gigabit laser
- 802.11an 2.4 gHz only
There are drops throughout the space. They are labeled with the corresponding number on the patch panel. Please don't destroy them (lol).
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: 10.20.0.90-10.20.0.94
- Gateway: 10.20.0.1
- Subnet: 255.255.254.0 (a "slash" /23)
- DNS: 10.20.0.1,220.127.116.11,18.104.22.168,22.214.171.124
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.
- See Network/testing.
Network Devices & Services
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.

NB: As of September 2017 this section is out of date. If you're interested in reviving this radio link hit up Patrick
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.
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].
Biketrailer is our humble router. It is an Ubiquiti Edgerouter (ER-4) 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.

We would like to setup IPv6, some day.
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.
Can I install/setup boxes on Noisebridge's network?
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 miners: 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.

Cyberpower UPS (Uninterrupted Power Supply)
All the rack infra is plugged into the UPS. If the power goes out, the UPS will provide battery power and also beep.
You can administrate the UPS through visiting http://cyber.noise on the Noisebridge wifi network, or by running pwrstat commands in the Pegasus machine (pegasus.noise)

People's Open Network
There are several nodes from the People's Open Network located at Noisebridge.
Nodes administered by sudo mesh
Here is a link to sudo mesh.
For info/assistance with these nodes you can contact email@example.com or ask on #peoplesopen.net on freenode IRC (try highlighting juul).
There is a Western Digital My Net N600 (configured as a people's open net home node) mounted on the ceiling close to the pillar by the library (NBiblioteca). It is black with white sides and held to the ceiling by two red straps. This node is announcing the following SSIDs:
- "peoplesopen.net 📡☠️": On 2.4 GHz channel 6. No password. All traffic routed through the sudo mesh VPN. Bandwidth limited to 50 mbits/sec.
- "peoplesopen.net 📡☠️ fast": On 5 GHz channel 157. No password. All traffic routed through the sudo mesh VPN. Bandwidth limited to 50 mbits/sec.
- "admin 📡☠️": On 2.4 channel 6. Has password. Not VPN'ed or bandwidth limited. Used to manage the node.
- "admin 📡☠️": On 2.4 channel 6 and 5 GHz channel 157. Has password. Not VPN'ed or bandwidth limited. Used to manage the node.
- "pplsopen.net-node2node": Ad-hoc mode for meshing. On 2.4 channel 6 and 5 GHz channel 157. No password. Uses babeld for meshing. Talk to sudo mesh for details.
The My Net N600 gives out IPs on the 100.65.9.192/26 range which is within the wider People's Open Network range from 100.64.x.x-100.128.x.x
The My Net N600 is connected to the switch above the main hacking tables (the one that has the braid of multicolored ethernet cables coming out of it) using a normal ethernet cable. This is where it gets is internet. Another ethernet cable runs from the node to behind the bottom of the indoor roof ladder where it connects to the non-powered port on a PoE injector. From the powered port on the PoE a grounded and shielded outdoor cable travels to the roof where it connects to a NanoStation M2 pointing east which is broadcasting:
- "pplsopen.net-node2node": Ad-hoc mode for meshing. On 2.4 GHz channel 1. No password. Uses babeld for meshing. Talk to sudo mesh for details.
- "peoplesopen.net noisebridge": Access point (master) mode. On 2.4 GHz channel 1. No password.
The NanoStation M2 is connected using its PoE passthrough ethernet port to a NanoBridge M5, which is mounted on a pole next to it. Currently the passthrough is not enabled and that NanoBridge is off. This is because the PoE injector needs to be upgraded to a beefier unit that can power both the NanoStation and the NanoBridge at the same time.
Nodes administered by Max B
The following was written by juul who was not part of installing any of this gear nor does he have admin access (I'm just writing what I'm seeing).
There is a Ubiquiti Bullet (not sure if M2 or M5) mounted out on the fire escape balcony with a high gain omni-directional antenna attached. This is connected via an outdoor shielded and grounded cable up over the side of the building and to a Western Digital My Net (N600 or N750, not sure) which is located in the metal box with the padlock on it. This node is not administered by sudo mesh. It is administered by Max B who is on the Noisebridge Slack.
