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


There is an external status monitor at [http://status.noisebridge.net/ status.noisebridge.net].
You see a "Noisebridge has an open WiFi network" sign.

=== '''24Mb/5Mb''' currently via Comcast ===
== Free Public Wireless Networks ==
* Comcast Cable (Only internet, no voice or tv service)
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.
** $66.95 per month (After taxes COD at time of install is $169.21) - $3 modem rental per month
** No contract!
** Link speed is ~24Mbit down / ~5Mbit up. More testing during different times of the day would be useful.
** Wonderful quote from the service representative when asked about network filtering: "The network is filtered. Dynamic ips.'' Constantly flowing.'' Upgrading to static is possible through the business department."
** The direct line for the person who took the order is 1-925-349-3300 x644201
** Our confirmation number for this order is: 503691


=== Speakeasy DSL ===
The following wireless networks (SSIDs) are active:
* Speakeasy DSL (On a dry pair - Ordered for the (415) 864 area)
* '''Noisebridge Cap'''
** Service has been delivered and installed at 83c
** No password
** Modem acts as a bridge straight into Speakeasy and comes with 1 static IP, 4 more for $20 per month.
** 802.11g/n/ac 2.4 and 5 gHz
*** Currently 66.92.8.180
** This is a temporary SSID set up for use during the move until the long term equipment is set up.
*** Additional IP added on Jan 26th (requires configuration on firewall) 66.92.8.123
** $105.95 per month - ($99.00 install fee, first month free, hardware included - Paid by Jake)
** Link speed: 6Mb down and 768k up
** 12 month contract (25 day trial period), $300 fee if canceled in contract but outside of stated trial period.
** 1 static ip included
** The direct line for the person (Michelle) who took the order is 1-877-240-4821
** In the future, we can upgrade the DSL to the following:
*** Kinda fast 8Mb down and 768k up. 149.95 per month. Hardware and install waved.
*** Super fast 10Mb and 1Mb up. 179.95 per month. Hardware and install waved.


=== Other uplink possibilities ===
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.
* Local wifi link (TBD - no current ETA on install)
We need an antenna and a wifi access point that will uplink to our core switch (we need one of those too)


* Metro fiber
__TOC__
** [[User:Jof|jof]] called IPN for a rough estimate for construction of fiber to 83c. The sales representative's estimate would be between 90,000USD - 100,000USD for the initial buildout.


* Sonic.net ADSL2
== [[Network Troubleshooting]] ==
We're on the waiting list for 18Mb/1Mb ADSL2
  Sometime in the next year service will be available in San Francisco.


* WiMax
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.
Currently this hasn't been very seriously researched


* SFLan
== Network Security Disclaimer ==
We may have line of sight to a node if we can bounce off of a local building. This hasn't been seriously researched. We may want to try to get roof access for antennas and should talk to our very quiet neighbors.


I was contacted by Matt Peterson about connecting. I would be happy to do a site survey to see if you can hit the SFLAN or City wirless deployment from the Valencia Gardens development. That could get you 40Mb/s up and down. - Tim Pozar

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


The /etc/hosts file is persistent now (it wasn't back when we used pfSense) so it no longer needs to be maintained on the wiki; the copy on the soekris is canonical now.

1. the wood/metal shop is very likely to cause your fans to become full

'''No.'''


2. the building floods in that corner every spring.

See [[Rack]].
We installed a *lot* of spare Cat5 capacity between the upstairs and
downstairs closets specifically so that there was no need to put more
gear downstairs.  Please just use the patch panel (label your patches or
they'll be removed!) and install gear upstairs instead.
 
(Of course things like DOCSIS mean that we need *some* gear downstairs,
but it should be
 
1. fanless
 
2. mounted on the wall or high up in the cabinet.)
 
 
 
=== Future Plans ===
 
Matt Peterson says:
 
In brief my suggestion is plug in both upstreams (Speakeasy ADSL and Comcast Cable) to the soekris,
run a trunk to the switches I donated and use the Cisco AP to beacon out 3  SSID's "noisebridge",
"noisebridge-dsl", "noisebridge-cable".  Each of these would map out to the various outbound ISP's
(some folks may want quicker flickr uploads or faster  firefox downloads or whatever), with the
generic SSID combined both connections (shunt ssh, sip and other latency stuff over the larger
outbound, the rest down the other  connection).  A shell script would monitor outages, reload pf
rules as needed if a connection goes down.  I got as far as making pf do the dual ISP network,
however I never setup the trunk on the switches or Cisco AP (though the equipment is floating
around the space).

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

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

EXITS: Hackitorium, Roll up door

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.

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).

Local Network Address Information

DHCP is offered automatically on the network. Currently the IP range is as follows:

  • IP Range: 10.21.0.1-10.21.1.254
  • Gateway: 10.21.0.1
  • Subnet: 255.255.254.0 (a "slash" /23)
  • DNS: 10.21.0.1, 1.1.1.1

Network Devices & Services


Uplinks

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.

Address Allocations

WAN - Monkeybrains - 192.195.83.128/29

  • Address range: 192.195.83.129-134
  • Gateway: 192.195.83.129

LAN - 10.21.0.0/16

10.21.1.0 - 1.254

  • DHCP Pool - When connecting to the network, you will automatically receive an IP in this range.

IPv6

We would like to setup IPv6, some day.

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

See Rack.
