Isolation is performed in 802.11 mesh. How to make this available to end-users? As of now, I see no good way to integrate the prototype into OpenWRT. This may be complex, because ut touches various configurations (WLAN, OVS, Mesh). Also, I'm not aware of any user-friendly IEEE 802.11 mesh configuration in OpenWRT or user-interface to wpa_psk_file. Is the a perspective for OpenWRT packages?

Those little SBC boxes have a good concept to store data securely and are ready for backups. I'll talk on the data storage concept used and how it's supposed for mutual (peer-to-peer) backups. On top of this, you can install Nextcloud using NextcloudPI. To make the setup easy for normal people, one can reach a personalized little box from the internet via HAProxy with SNI redirecting to a personal Wireguard tunnel. This setup is suitable if your provider gets you behind CGNAT or MAP-T or in cases you simply are un-able to configure port forwarding yourself. The plan is to make money for my local hackspace offering (payed) courses to people e.g. how to master those little beasts, how to link your smartphone to them, how to use a password manager, and how to secure / restore your backups.

They empower local communities, promote digital sovereignty, and strengthen Internet openness. With the increasing centralization of Internet infrastructure, community-driven approaches such as CN and Community IX offer practical, values-driven alternatives. Among others, several Freifunk groups are members of our Community IX. These grassroots collaborations provide concrete pathways toward resilient, community-based interconnection models — highly relevant in today’s Internet governance and policy discussions. As a long-time community networks advocate and co-founder of freifunk.net — one of the largest CN initiatives in Europe — I see great potential: ISOC Chapters can play an important role in making these efforts more visible, scalable, and policy-relevant. In Europe, we have had to face some setbacks in recent years — including regulatory and funding challenges. But with a strong grassroots Internet culture and active Chapters, we still offer fertile ground to advance this work, with valuable lessons for other regions. Bringing this topic into the SIG ecosystem for 2026–2027 would: • Align strongly with ISOC’s mission (an open, globally connected, secure, and trustworthy Internet for everyone) • Provide hands-on opportunities for ISOC Chapters — with potential global relevance • Foster cross-cutting collaboration with existing groups (former CN-SIG members, DC3, Gender SIG, Youth SIG, Accessibility SIG) PUBLIC CONFIRMED Workshop - 1 hour https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/GRVPE7/ Rautenkranz Monic Meisel Adam Burns PUBLISH XPGMNW@@pretalx.freifunktag.de -XPGMNW Flow Offloading via eBPF en en 20250614T160000 20250614T162000 0.02000 Flow Offloading via eBPF PUBLIC CONFIRMED Talk - 15 min + 5 min Q&A https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/XPGMNW/ Rautenkranz Til Kaiser PUBLISH DKQVDM@@pretalx.freifunktag.de -DKQVDM Mesh Graph Viewer en en 20250614T173000 20250614T175000 0.02000 Mesh Graph Viewer PUBLIC CONFIRMED Talk - 15 min + 5 min Q&A https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/DKQVDM/ Rautenkranz mwarning PUBLISH RCZULN@@pretalx.freifunktag.de -RCZULN OpenWrt as a smart bootloader chainloader en en 20250614T180000 20250614T182000 0.02000 OpenWrt as a smart bootloader chainloader PUBLIC CONFIRMED Talk - 15 min + 5 min Q&A https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/RCZULN/ Rautenkranz G10h4ck PUBLISH HWAJSK@@pretalx.freifunktag.de -HWAJSK Working Group for a Further Development of the "Pico Peering Agreement" en en 20250614T182000 20250614T195000 1.03000 Working Group for a Further Development of the "Pico Peering Agreement" PUBLIC CONFIRMED Workshop - 1 hour https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/HWAJSK/ Rautenkranz Mathias PUBLISH JANDRV@@pretalx.freifunktag.de -JANDRV DIY: Fibre jetting, splicing and testing en en 20250614T100000 20250614T120000 2.00000 DIY: Fibre jetting, splicing and testing PUBLIC CONFIRMED Workshop - 2 hours https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/JANDRV/ Saal Bluse PUBLISH APAX9A@@pretalx.freifunktag.de -APAX9A Workshop: Further Discuss ISOC SIG Ideas en en 20250615T103000 20250615T110000 0.03000 Workshop: Further Discuss ISOC SIG Ideas PUBLIC CONFIRMED Workshop - 1 hour https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/APAX9A/ Rautenkranz Mathias PUBLISH QE9JWB@@pretalx.freifunktag.de -QE9JWB KConfig Utils how to programmatically deal with your .config en en 20250615T110000 20250615T112000 0.02000 KConfig Utils how to programmatically deal with your .config PUBLIC CONFIRMED Talk - 15 min + 5 min Q&A https://pretalx.freifunktag.de/battlemesh-v17-2025/talk/QE9JWB/ Rautenkranz G10h4ck PUBLISH M7CRBA@@pretalx.freifunktag.de -M7CRBA Workshop & Discussion about a Community-Network/Community-Infrastructure web page (similar to HackerSpace Wiki) en en 20250615T112000 20250615T122000 1.00000 Workshop & Discussion about a Community-Network/Community-Infrastructure web page (similar to HackerSpace Wiki) Topics: - what are the needs of the communities? - what structured information should be available? - how could we do it?
