@tom:dragar.deTom

btw. if you've got problems upgrading your IPv6 only NixOS you might want to check that you're using channels.nixos.org instead of NixOS.org/channels/

@tom:dragar.deTomjust mentioning it because the chance is probably higher then average in this room that it affects someone else 😅13:29:30

@elisaado:matrix.orgelisaado interesting 17:20:54
@jappie:jappie.devjappieI used to while studying at uni: networkd w/ ipmasquerading, ipforwarding & dhcp server and hostapd for wifi, all on an rpi :p17:30:03
@hash:hcrypt.nethashdo you run a slim version of nixos or the default image?18:07:36
@k900:0upti.meK900What is a "slim version of nixos"?18:13:29
@albertlarsan68:albertlarsan.frAlbert Larsan The *-small channels aren't actually slimmer, they are jsut updated more frequently due to having less packages built for it. 19:16:51

@elisaado:matrix.orgelisaadooh fun, did it work well?02:02:39

In reply to @autiboy:matrix.mautiweb.net
How do you all have it setup?

Combination of IfState for interface configuration (supports network namespaces and vrf's), nftables and frr for dynamic routing

I also run it in a BPI-R4 similar to K900, but I haven't finished this project yet... Wifi not working yet

08:05:20
@magic_rb:matrix.redalder.orgmagic_rbMy flatmate flashed openwrt on my bpi-r4...08:06:21
@magic_rb:matrix.redalder.orgmagic_rb boring 08:06:33
@jappie:jappie.devjappieit was good enough, wired worked fine, wifi was of course not the fastest and the signal didn't reach the shared accommodation, but it was a fun project and I didn't have any real outages / things going wrong08:22:53
