Encrypted wireless only means that anything transmitted between your laptop and the Wifi access point is encrypted. '''This does not guarantee security or privacy at all.''' Someone malicious could simply sit in between the "internet" and the Wifi access point and sniff all of your traffic after the access point unencrypts it, or they can simply figure out how the encryption functions and sit in on what your transmitting, or you use an encryption method that is already broken.

Network Troubleshooting

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.

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.

As much as anyone volunteering at the space could state that we (Noisebridge) can provide you with a secure web browsing experience, this view may not be reflected over all of its members and participants (which is the actual case). Please take our advice and services with a grain of salt and understand that the only sure secure network is one that you setup and operate yourself.

Thank you for reading, please continue now on creating interesting things.

Wireless networks

Free Open Unsecure Wifi

Noisebridge generally has two or more unencrypted open wifi access points available for your use. If you can see the "noisebridge-a" network, congratulations, you have an 802.11a-compatible card and should use this network as it is better faster and stronger than the others. If you cannot see noisebridge-a, either it is not working or you do not have an 802.11a card. You probably have an 802.11g card. Hopefully you can see the "noisebridge" network, which is the one you should use in that case. Like any public network, you should regard noisebridge's as potentially hostile and take appropriate precautions.

The following networks are active at 2169 now:

  • noisebridge - No encryption, NATted via the Sonic.net and Monkeybrains links, 802.11bg
  • noisebridge-a - No encryption, NATted via the Sonic.net and Monkeybrains links, 802.11a
  • noisebridge-tor - No encryption, all traffic transparently proxied through tor.

Free Encrypted Unsecure Wifi

There are sometimes "secure" or encrypted wireless networks running at Noisebridge for research purposes. Please do not assume that these networks are in any way safer than an open network is; they are not.

Encrypted wireless only means that anything transmitted between your laptop and the wifi access point is encrypted. This does not guarantee security or privacy at all. Someone malicious could simply sit in between the Internet and the wifi access point and sniff all of your traffic after the access point unencrypts it, or they can figure out how the encryption functions and sit in on what you're transmitting, or you use an encryption method that is already broken. In any case, using an encrypted wifi network does not provide any useful security benefits at Noisebridge.

NOTE: No technology 'guarantees' security or privacy. The above statement is true, and using the encrypted wifi network at Noisebridge doesn't give you more security, since the shared secret is widely known and the space is not secure. But WPA2 is a useful technology in general, and it's not practical to brute force if the key is longer than 13 random characters. By comparison, people who use unencrypted wireless are subject to trivially easy packet sniffing over the wire.

In most cases you may encounter more problems trying to get "online" through one of the encrypted networks than using one of the open ones.

A few members of the space have gone out of their way to make the Internet run as smooth as possible; part of that is disabling these so-called secure networks [where do we call this "secure"?] to give room for the legitimate[citation needed] open ones that work a whole lot better[citation needed].

You may want to see the WiFi Pineapple Mark IV in action to see how easy it is to honeypot a WIFI.

DNS

Dynamic DNS is provided by the nat machine for DHCP clients on 172.30.0.30/22. Resolution of machines with static addresses is done by ipv4 or ipv6 mDNS and dynamic DNS entries on the nat machine from the DHCP service.

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:

  1. Configure a computer for 192.168.1.253/24.
  2. Connect the computer to the DSL CPE.
  3. Power cycle the DSL CPE.
  4. Connect to 192.168.1.254 using your web browser.
  5. You will be prompted to set a password, use the serial number on the bottom of the DSL CPE.
  6. Get into expert mode.
  7. Under configure->connections, set the following:
    1. VPI: 0
    2. VCI: 35
    3. Protocol: Bridged Ethernet LLC/SNAP
    4. Bridging: on
  8. Under configure->DHCP server, set the following:
    1. DHCP Server Enabled: unchecked
  9. Save and reboot.

Monkeybrains Wireless Link

We have a point-to-point wireless link to Monkeybrains on the roof.

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.

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.

Routers

Currently, DHCPd is handing out a default gateway (172.30.0.2) that belongs to bikeshed.noise

bikeshed

The primary noisebrdige router for our is a Soekris running Vyatta(a Linux-based router distribution).

The machines currently provides

  * dhcpd
  * DNS (dnsmasq) - .noise local TLD and recursive proxy
  * Automatic loadbalancing and ailover between Sonic DSL and monkeybrains

Access is via SSH with keys.

Address Allocations

The reserved address allocations are:

75.101.62.88/29 from Sonic.net

We have a range within the encompassing /24: 75.101.62.{88..95}

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.

Dial Backup

There is a modem connected to 415 800 6786 which you can call to talk to an mgetty process on the ops machine. This may be handy if the upstream Internet connections aren't working or you locked yourself out by accident. Please don't dial out on the modem, it costs money. Inbound calls on that circuit are free.

The modem is a US Robotics 56K Corporate Analog Modem. If you don't have a modem in your computer, you might be able to call it using your mobile phone. Just tether your phone to your computer like you normally would, but call our modem instead of calling the number to start the tethering connection.

The modem has its remote access feature enabled. Read the manual for details.

IP PDU

There is an IP PDU (model "IP 9258") at 172.30.0.7 which can be used to power cycle some of the devices in Susan the Rack.

To change the state of the power ports, you'll need to telnet in and run "setpower=11000000". Each index represents a port, "1" is on and "0" is off. Port 1 sometimes doesn't turn on unless you use the web interface, and it might take a couple requests. Just keep clicking the apply button until it looks like power has been applied.

Changing some settings on the IP 9258 in the web interface may result in the power being cycled on some of the ports. Don't change settings unless you're prepared to deal with machines spontaneously resetting.

KVM

There is no KVM, but there are monitors and a keyboard dedicated to the machines in the rack. You can easily recognize it because it's covered in nail polish and you can't see the keycaps. The delete key is in the upper-right corner of the keyboard, which is handy to know if you want to get into the BIOS of the machines.

Other uplink possibilities

  • Metro fiber
    • 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
    • We have this, woot.
  • WiMax
    • Currently this hasn't been very seriously researched
  • SFLan

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
