Network @ Calafou

Network documentation

Surely outdated :) In bold : the present page

ISP

Internet is provided by https://somvera.cat/ with https://guifi.net/ red

pfSense

At the head of the network, there is a pfSense computer that manage part of the network

Backbone

The backbone is a ring of managed switches and twisted pair Ethernet cables that is the central part of the Calafou IP network.

Managed switches

Note: we are preparing these devices to put on the network so they are not installed in production yet.

TP-Link TL-SG2008 devices

SSH access: this is tricky because the SSH server on the device is old. You have to enable legacy options to connect:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-dss admin@172.31.17.XYZ

You can learn more about using legacy options with SSH here: https://www.openssh.com/legacy.html

The command line (SSH/Telnet) interface is not a standard UNIX shell, but a TP-LINK specific system described in the manual of the device.

Manuals can be downloaded from the vendor's website here: http://www.tp-link.com/en/download/TL-SG2008.html

Calafou specific configuration:

  • IP address 172.31.17.XYZ
  • Hostname backboneXYZ (XYZ is the location, like "redhouse" for example)
  • Telnet on (there is username/password authentication on this)
  • SSH on
  • NTP (Network Time Protocol) on, timezone CET, European daylight saving enabled
  • STP on (rapid STP, also called rSTP)

Authentication: same username and password on HTTP, HTTPS, TELNET and SSH.

  • Username: admin
  • Password: you can find it in the calafou keyringer repository in the key file "calafou.lan.BackboneSwitches.asc"
