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.

DNS

Dynamic DNS is provided by the nat machine for DHCP clients on 172.30.0.30/24. 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.

Wireless networks

The following networks are active at 2169 now:

  • noisebridge - No encryption, NATted via the sonic.net link, 802.11bg
  • noisebridge-a - No encryption, NATted via the sonic.net link, 802.11a

2169 Mission

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. 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.

Motorola 2210 User Guide

Router

The router is a soekris 4801 running Matt Peterson's crazy OpenBSD build. Its WAN address is 75.101.62.88/24 and its LAN address is 172.30.0.1. Access is via SSH with a key.

DHCP and DNS services are being provided by it as well, and it has a DNS forwarder. DHCP spits out addressed from 172.30.0.200 and update.

Address Allocations

The reserved address allocations are:

75.101.62.88/24

We have a range within the class C. 75.101.62.{88..95}

  • .88 - router
  • .89 - pony
  • .90 - stallion (was s1)
  • .91 - Unallocated
  • .92 - Unallocated
  • .93 - Unallocated
  • .94 - Unallocated
  • .95 - Unallocated

172.30.0.0/22

  • .1 - r00ter, main soekris router connected to the sonic.net DSL
  • .2 - gorilla, soekris router hooked up the monkeybrains link
  • .5 - PS3 (goat), usually powered down to save power
  • .6 - treechopper, Laserjet 5Si MX
  • .7 - OpenGear IP Power 9258 in supply closet (power1)
  • .8 - Dell switch (switch1)
  • .10 - stallion
  • .11 - Pico AP 802.11bg (ap1) not used
  • .12 - Powerstation AP 802.11a (ap3)
  • .13 - Cisco Aironet 1100 series (ap2)
  • .14 - Cisco Aironet 1100 series (ap4) (not deployed)
  • .30 - Pony, main sandbox server
  • .41 - Zebra, Rebar and jukebox, Brother print server
  • .42 - Ass, greeting terminal
  • .44 - Horsy. media center

10.100.4.0/23 ChaosVPN Range

IP PDU

There is an OpenGear IP 9258 at 172.30.0.7 which can be used to power cycle some of the devices in the DJ booth bread rack.

Port Device
1 stallion (was s1)
2 pony
3 unused
4 unused

Machine Rack

The rack of machines and switches is counted by U, from the bottom, starting from "1".

Port Device
24 small stuff - airlink, soekris, ethernet hub
20-23 unused
18-19 patch panel
17 switch1
16 2 - jim's, for linux user group
15 1 - jim's, for linux user group
14 hammer - aestetix
12-13 unused
7-11 pony
5-6 rack support for pony
4 unused
1-3 APC

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

  • 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 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
