BinnenNet

Since the spaghetti-network at Interference there was the plan to combine all the networks at the Binnenpret and share data/info/services on it. This has now happened! Binnenpret has one unified network used by all spaces. There is a shared 1 Gb/s internet uplink, connected by switches and wifi accesspoints. There is a network monitoring system.

Troubleshooting

The network uptime is very high, issues rarely occur. The only recurring ones:

  1. Power switched of in fuseboxes by people doing maintenace. Check for people doing builing maintenance. Otherwise check these fuse boxes:
    1. at the end of the short corridor leading to silkscreen printing workshop and rehearsal room (next door to LAG).
    2. in the hallway next to bollox
    3. in the binnenpret office opposite the mkz backdoor (key in Bollox).
  2. Outage in the internet uplink. Check https://freedom.nl/storingen.
  3. Someone unplugged the LAG wifi accesspoint. It is the white plate on the ceiling. Check if ap-lag is online here: http://10.13.12.2/

Other issues will be more complex and may require access to various admin interfaces to resolve. See below for more info.

Do not reset/restart any devices, it makes problems worse instead of better. Never hard-reset any devices.

Internet connection

Freedom Internet (freedom.nl) over KPN fiber optic line. Location: binnenpret office.

Switching

  • TP-Link TL-SG3424P. Location: hallway next to silkscreen workspace. http://switch-meterkast-amok.fritz.box
  • TP-Link TL-SG3424P. Location: bollox toilets. http://switch-bierhok-bollox.fritz.box
  • TP-Link TL-SG108PE. Location: binnenpret office. http://switch-kantoor.fritz.box

WiFi

13x Ubiquity U6 Pro. They receive power from the switches by Power over Ethernet.

There are various SSID's like:

  • LAG
  • Binnenpret
  • Binnenpret guest

All SSID's are one the same network, there is no separation by VLAN. (Maybe on Binnenpret guest host-to-host communication is restricted?)

They are centrally managed from https://10.13.12.2:8443/manage/account/login?redirect=%2Fmanage. Acces limited, because of privacy issues.

Monitoring

LibreNMS. http://10.13.12.2/ Acces limited, because of privacy issues.

Server

Hewlett-Packard HP t620 Quad Core TC running Debian. Location: hallway next to silkscreen workspace.
