=== Free Open Wifi ===
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 [[Visitor_advice#Hostile_network|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 Sonic.net and Monkeybrains
** 802.11gn 2.4 gHz and 802.11an 5 gHz, your wifi device decides which network is the best for it and roams accordingly
* '''Noisebridge 5g'''

=== DSL Circuit ===
There is a Sonic.net Fusion ADSL2+ DSL connection in the building.  The physical circuit comes in from the MPOE in the basement and runs across the roof of the basement and up the side of the building into the DJ booth (Tea Room), then over to the Wall o' Tubes.  The CPE is a Motorola 2210 ADSL2+.  The admin password is the serial number, written on the bottom. 
The addressing configuration is a little unusual. It's 75.101.62.0/24 and we've been allocated a /29 within that block: 75.101.62.88 - 75.101.62.95.  Note that we get to use all 8 addresses; the broadcast and network address are 75.101.62.255 and 75.101.62.0 respectively.  The gateway is 75.101.62.1.
The default CPE settings are not correct for our circuit configuration.  From a factory reset, do the following to configure the CPE:
# Configure a computer for 192.168.1.253/24.
# Connect the computer to the DSL CPE.
# Power cycle the DSL CPE.
# Connect to 192.168.1.254 using your web browser.
# You will be prompted to set a password, use the serial number on the bottom of the DSL CPE.
# Get into expert mode.
# Under configure->connections, set the following:
## VPI: 0
## VCI: 35
## Protocol: Bridged Ethernet LLC/SNAP
## Bridging: on
# Under configure->DHCP server, set the following:
## DHCP Server Enabled: unchecked
# Save and reboot.

==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 channel in the Noisebridge Slack.


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.
== Router ==
 
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.
 
== Access Control==
 
Most hardware is set to use the most guessable logins and passwords possible. If you're interested in logging in, just make some guesses as to what the login can be. Use your favorite search engine. Poke around. Hack.
 
Experience the thrill of guessing a password that just works.

=== IPv6 ===
 
We have IPv6 support on the DSL circuit via a tunnel provided by sonic.net.  Some details on how to get the OpenBSD-based flashrd distribution on the routers to tunnel correctly can be found on the [[Flashrd]] page.
 
Note that using IPv6 in some situations can result in people knowing what model of computer you have and the network card's serial number, because of the way IPv6 stateless address configuration works.  If this is a concern, tell your computer not to use IPv6.  Ask around Noisebridge if you need help or want more details.
 
==== 2001:5a8:4:5630::/60 ====
 
This is the IPv6 subnet assigned to us by sonic.  We only use the bottom /64 of this /60 so automatic address configuration works right; the other 15/16s of the address space are intentionally wasted.  r00ter hands out IPv6 router advertisements for this subnet directly.  They're directly routable, but unsolicited incoming traffic is blocked by the firewall to protect the users.  This means you can't run an IPv6 server on our IPv6 subnet, but you can connect to other machines on the IPv6 Internet just fine.  If you really need to run an IPv6 server for some reason, consider using Teredo.

You are standing beneath Noisebridge's network rack on the wall in the Hackitorium.

You see a "Noisebridge has an open WiFi network" sign.

The open WiFi networks are free to all at Noisebridge. 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.

Free Public Wireless Networks

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 wireless networks (SSIDs) are active:

  • Noisebridge Cap
    • No password
    • 802.11g/n/ac 2.4 and 5 gHz
    • This is a temporary SSID set up for use during the move until the long term equipment is set up.

If you're reading this from another point in time, please note that the reality of the situation may be different. Please update this page to reflect reality as it changes.

Network Troubleshooting

Monkeybrains Wireless Link

We have a point-to-point wireless link to Monkeybrains on the roof, it's a microwave dish on the roof at the front of the building.

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 channel in the Noisebridge Slack.

Router

Biketrailer is our humble router. It is an Ubiquiti Edgerouter (ER-4) box running EdgeOS, a fork of Vyatta (a Linux-based router distribution).

The machines currently provides

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

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

Access the router UI over https at 10.21.0.1.

Machine Rack

The rack layout, subject to change

There are two racks in the space, the main one on the first floor near the rolling door, and the secondary one on the second floor directly above the main one. They are small and up high to discourage people from messing with them or installing things in them. The internet works, please leave the boxes alone.

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

Short answer

No.

Long answer
