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 Monkeybrains link, 802.11bg
  • noisebridge-a - No encryption, NATted via the Monkeybrains link, 802.11a

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). The CPE is a Motorola 2210 ADSL2+ and is just outside the Tea Room on the floor. 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.

Routers

Currently, DHCPd is handing out a default gateway (172.30.0.3) that floats between r00ter and gorilla for automatic ISP failover.

r00ter

The Sonic.net router is a Soekris net4801 (hostname: "r00ter") running OpenBSD with some modifications to support running with a flash-backed root filesystem. 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 r00ter as well: it has a DNS forwarder (dnsmasq), and dhcpd spits out addresses from 172.30.0.0/22 (172.30.0.200 and up).

gorilla

The router for our Monkeybrains link (hostname: "gorilla") is also a Soekris running a similar OpenBSD installation. Access is via SSH with a key.

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}

  • .13 - Cisco Aironet 1100 series (ap2, above the supply closet)
  • .14 - Cisco Aironet 1100 series (ap4, above the Eastern windows)
  • .15 - Cisco Catalyst 3500 XL (switch3)
  • .16 - Cisco Catalyst 3512 XL (switch4)
  • .30 - Pony, main sandbox server
  • .31 - Touchpanel by the door
  • .32 - Touchpanel by the bar
  • .34 - Linux Study Group Linksys BBEFS41 Router
  • .41 - Zebra, Rebar and jukebox, Brother print server
  • .42 - Ass, greeting terminal
  • .44 - Horsy. media center

172.30.0.128/25, 172.30.1.0/24, 172.30.2.0/24, 172.30.3.0/24

  • DHCP-assigned, user-access IP space

172.30.4.0/24 (Tor-ified network)

  • .1 - "torbridge" interface on pony
  • .2 - "noisebridge-tor" access point.
  • .10 - .254 -- Tor-ified clients (served by DHCP)

10.100.4.0/23 ChaosVPN Range

  • Network in the ChaosVPN
    • Has yet to be setup. In the future, we may join the network so that we can route to other hackerspaces

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.

It seems that in the case of power loss, the ports do not restart on the "On" state. In this case, you'll need to telnet in and run "setpower=11000000". Each index represents a port, "1" is on and "0" is off. Whomever wrote something so confusing can die in a fire, please.

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
