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.  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 CPE is programmed to provide DHCP services on its internal address, 192.168.3.0/24.  It's configured to do concurrent routing and bridging.  This means if it sees packets from 192.168.3.0/24 it will NAT them and if it sees packets from 75.101.62.88/29 it won't.  The bottom line is that if you want to be on the public block, just grab yourself an address on it and things will Just Work.

Status

There is an external status monitor at status.noisebridge.net. If something is wrong with the network at 83c, you should contact an admin.

The Ops personnel can be reached by calling (650) 248-2445 24/7.

It's 2 AM And The Admins Are Asleep

If no admin responds within a reasonable period of time (say, an hour), take matters into your own hands and send mail to noisebridge-discuss with answers to the following questions:

  • Who are you?
  • What happened?
  • When did the problem begin? (If you were able to find out.)
  • When was the problem noticed?
  • When did it get fixed?
  • What did you do to fix it? Please err on the side of too much detail rather than not enough.

Please try to observe the guidelines for network maintenance, but use your Most Excellent Judgment if something there doesn't seem to apply.

Logical Topology

Logical topology
  • The Soekris provides NAT / Firewalling to hosts inside of 172.30.0.0/24 -- the "inside" network.
    • The same Soekris holds an external IP from Comcast on sis2, an external IP from Speakeasy on sis1, and 172.30.0.1/24 on sis0.
    • Current Comcast IP: 24.5.85.158/21 (Comcast will now only hand out a DHCP lease requested from 00:0A:E4:32:44:6E)
    • Current Speakeasy IP: 66.92.8.180/24
  • Internal subnet is 172.30.0.0/24
    • Soekris box is at 172.30.0.1
    • switch1 is at 172.30.0.3
    • Ruckus AP (needs hostname) is at 172.30.0.5
      • Default login is "super"/"sp-admin"

Physical Topology

Physical topology

Huge JPEG of pony's closet

Connectivity to the outside comes over one copper POTS circuit (Speakeasy/Covad) and some RG-59 coaxial cable. Both circuits terminate in the closet attached to the shop/fishbowl. Most of the networking equipment has moved to the upstairs closet attached to the electronics lab. Still downstairs is the DOCSIS (Cable) modem, as the coax coming in couldn't easily be moved to the upstairs closet.

The copper Ethernet connectivity to baseboard connectors downstairs and the DSL/POTS circuit has been patched to the patch panel in the upstairs closet.

Uplinks

24Mb/5Mb currently via Comcast

  • Comcast Cable (Only internet, no voice or tv service)
    • $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

  • Speakeasy DSL (On a dry pair - Ordered for the (415) 864 area)
    • Service has been delivered and installed at 83c
    • Modem acts as a bridge straight into Speakeasy and comes with 1 static IP, 4 more for $20 per month.
      • Currently 66.92.8.180
      • 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

  • 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
    • 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're on the waiting list for 18Mb/1Mb ADSL2
 Sometime in the next year service will be available in San Francisco.
  • 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


DNS

Internal machines (with NAT addresses in 172.30.0.0/24) have names in the .noise pseudo-TLD. These names are managed on the Soekris in /etc/hosts (NOT in a zone file). After editing /etc/hosts, you can SIGHUP the dnsmasq process to trigger a reload.

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.

Wireless networks

The following networks are active at 83c now:

  • noisebridge - insecure, NAT via Speakeasy and/or Comcast

The following networks are disabled in the Ruckus AP config:

  • nbsweden - insecure, NAT to Relakks. not yet functional. vlan 21.
  • nbgermany - insecure, NAT to Germany via CCC. not yet functional. vlan 31.
  • nbipv6 - insecure, IPv6 only. not yet functional. vlan 41.
  • nbanonymous - insecure, transparent Tor. not yet functional. vlan 51.
  • nbwpa - "secured" (so they say) using WPA. not yet functional. vlan 61.
  • nblocal - insecure, local-only. No Internet route. not yet functional. vlan 71.

Interim Configuration

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. 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 CPE is programmed to provide DHCP services on its internal address, 192.168.3.0/24. It's configured to do concurrent routing and bridging. This means if it sees packets from 192.168.3.0/24 it will NAT them and if it sees packets from 75.101.62.88/29 it won't. The bottom line is that if you want to be on the public block, just grab yourself an address on it and things will Just Work.

The reserved address allocations are:

75.101.62.88/29

  • .88 - DSL CPE
  • .89 - Unallocated
  • .90 - s1
  • .91 - Unallocated
  • .92 - Unallocated
