Minutes

Meshnet

First DEA Nodes

orimpe presented a slide deck, showing the locations of nodes we'll install:

POE Node: Useldeng, Marnach

Solar Node: Eschduerf, Derenbach, Roullingen, Napoleonsgaart

orimpe then opened lux.meshmapper.net to present the state of the network in Luxembourg, showcasing the new nodes.

orimpe also showed a spreadsheet with the possible locations, their reach and their rating, that is, how far they reach and thus how useful they are.

Dutch Meshcore - Switch to SF7

orimpe also presented another document: Dutch Meshcore - Switch to SF7, lowering the "spreading factor", getting better performance, but breaking compatibility with the rest of the network. They have done this as the network has gotten too busy.

Meshnet.lu website

xbr will migrate the repository from kallithea to forgejo, and orimpe and virii will start writing some content.

Meshnet.lu stickers

virii got various Meshnet.lu stickers and brought them to the ChaosStuff.

New Antennas

virii has bought some new antennas for testing from various manufacturers:

Allnet 3dBi] * [[https://www.reichelt.de/de/de/shop/produkt/lora_wan_antenne_868_mhz_5_dbi_n-buchse-317057|Allnet 5dBi

Poynting 4.5dBi

Interline 8dBi

Freifunk Update

xbr: It works again!

virii and orimpe tested it in the ChaosStuff, IPv4 works but limited speed due to encryption, and IPv6 does not work. This is due to the lack of routing rules and handing out of IPv6 addressing.

Freifunk could become more event-oriented, but it might have to be a different model, as meshing (wireless) would not necessairly make it ideal.<br> If we bought cheap used enterprise equipment and loaned it out for a donation, optionally even having some people help and set it up, that could be cool, but a completely different model and require more labour and equipmnt.

Alternatively, Freifunk could host services. Sadly, hosting it in Germany and calling it "freifunk.lu" is kinda crappy. Finding hosting in Luxembourg is very difficult and expensive, there are no VPSes, we'd need to get something sponsored.

Admin

LBR & BCEE

We updated the information in the LBR:

RCS: Modification portant uniquement sur les mandataires

RBE: Modification des bénéficiaires effectifs

For the BCEE account, we need to change the acceses, there might be a PDF form, but we have to go in-person. virii will take a look and ask.

FVDE

FVDE still exists on paper, but the AGA has closed it.

We took a look at the LBR form, it seems possible to close it, but a minimum of information is required (closure date, etc.).

virii: fantawams should've done it, but was not able to. I'll take a look at it

Update phone number

We have to update the targets of the phone, to virii and xbr.

virii has sent the email.

When someone calls the C3L number, it rings the other people, with the C3L number as the origin.

NOC

Updates from the NOC (regarding ChaosStuff Network)

virii: we sent the Archer C7 in retirement, we replaced it with TP-Link Omada, with a controller and APs, IPv6 works now.

The FritzBox has been removed, we only use the CZ.NIC Omada, the photo club shares the network with us now.

virii has removed all broken and non-working devices from the NOC rack: old backup system, roonadan, the other Pi that virii had, etc.

We do want to install a new system(s) (e.g. Pi) in the NOC rack for MQTT, Grafana, and other internal systems.

Problems due to (lack of) MQTT in ChaosStuff

We need MQTT in the network, for lights (Zigbee2MQTT), the red button still uses MQTT, but that could be changed. MQTT is not necessiarly a bad choice, but we must re-configure it. Possibly the scripts and older config could be gotten from the roonadan SD card.

The DECT power switches and the alarm (open/closed) run over HTTP calls (GET/POST).

.lu domains

xbr will move freifunk.lu from VO to a new my.lu account.

kallithea to forgejo migration

We need to migrate repos to forgejo, xbr will start migrating some important repos.
