Calafou Network Log

It is a small attempt to reconstruct the history of our network and to keep daily annotations about its failures and improvements.

Epoch After Moment Zero

Mon Oct 10 22:10:15 UTC 2016

• At the moment the ring is phisically interrumpted between hacklab and suk. The cable on suk is unplugged. I think we could have been victims of a chernobyl packet that generated broadcast radiation.
• There is a hand forged packet with TTL set to 0 that is circulating the network. If somebody sees it, please catch it. (src=172.31.18.25, dst=224.0.0.1 .)
• There's a more specific forwarding rule on suk that only allow to exit only ipv4 packets.

Moment Zero

Mon Oct 10 21:25:53 UTC 2016. A new era begins.

Please refer in a normal conversation to a network problem in terms of BMZ or AMZ.

Examples: "This was a BMZ problem, now we have different problems" or "We are observing this AMZ issue, but we know that it has a BMZ origin".

Epoch Before Moment Zero

We have really few memories of this epoch. Please help us reconstruct our network memory! Let's try to keep it in descending chronological order.

New Antenna

May 14 2016 . After years of rough signal we installed a new Antenna.

Omnius power supply break down

May 08 2016 . A new power supply is installed on omnius.

Apr 29 2016 . Electronic experiments were conduced in hacklab and omnius' power supply burnt out.

suk:/etc/hosts on git

Apr 30 2016 . We decided to track our main hosts file on git. So the router can pull periodically new changes and those changes don't need to be done inside the suk shell.

Acarina in the backbone

[Please fill me] . Another challenge: flash a Mikrotik RB-250GL with OpenWrt. Finally achieved and running in ofitec.

STP

[Please fill me] . Our good/evil friend hark setup STP on calafou network during the preparations of BB409.
