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"
