@hexa:lossy.networkhexa (clat on linux when)does the kernel still log martian packets to dmesg? 🤔16:47:15
@raboof:matrix.orgraboofnot sure, dmesg is pretty quiet on this machine at least16:47:55
@raboof:matrix.orgraboof ha, disabling networking.firewall.checkReversePath seems to have done the trick :). thanks for pointing in that general direction 16:56:40
@hexa:lossy.networkhexa (clat on linux when)yeah, same shit, different stack16:59:12

@raboof:matrix.orgraboofyay17:06:20
@hexa:lossy.networkhexa (clat on linux when) why aren't you buying into orb instead? https://orb.net/ 17:37:02
@hexa:lossy.networkhexa (clat on linux when)(anyway, I think they're a nice product to take inspiration from)17:37:33
@raboof:matrix.orgraboofNeat, never seen it before. Yeah I thought "I'll just throw something together real fast". A blackbox-exporter patch, autossh conflicting with nixos-rebuilder-ng and this rp thing later it didn't quite turn out like that, but still enjoying the learning 😊18:40:48
@elisaado:matrix.orgelisaadothe topic mentions "do not rely on networking.*", why is that? networking. options are so comfy :(23:02:45
@tom:dragar.deTomFrom my understanding: networking.* (without the networking.useNetworkd Option which is problematic in itself) is a bunch of scripts and systemd services which try to configure networking. It's just not the way to do it and networkd and networkmanager will be more robust.23:27:26
@hexa:lossy.networkhexa (clat on linux when)nobody really maintains those scripts23:28:51
@hexa:lossy.networkhexa (clat on linux when)and they don't keep pace with the network management tools out there23:29:04
@hexa:lossy.networkhexa (clat on linux when)and in fact no other reasonable distro does this23:30:26
@hexa:lossy.networkhexa (clat on linux when)debian did this with ifupdown, but that's largely a legacy project23:30:33
@hexa:lossy.networkhexa (clat on linux when)and ubuntu doubled down on another abstraction layer with netplan23:30:43
@hexa:lossy.networkhexa (clat on linux when)for headless setups we have networkd and ifstate23:31:13
@hexa:lossy.networkhexa (clat on linux when)and for headful ones the only reasonable contender is networkmanager23:31:31
@hexa:lossy.networkhexa (clat on linux when) mellanox did develop ifupdown2, which provided ifreload for gradual migrations between old and new config, really neat 23:32:03
@hexa:lossy.networkhexa (clat on linux when) * cumulus did develop ifupdown2, which provided ifreload for gradual migrations between old and new config, really neat 23:32:13
@hexa:lossy.networkhexa (clat on linux when)not sure how well maintained it is these days, but it builds upon the config format established by ifupdown itself, which is … not so nice23:33:01
@hexa:lossy.networkhexa (clat on linux when)https://github.com/CumulusNetworks/ifupdown223:33:02
@hexa:lossy.networkhexa (clat on linux when)and of course there is ifupdown-ng (e.g. provided on alpine) in that ifupdown lineage https://github.com/ifupdown-ng/ifupdown-ng23:34:00
@hexa:lossy.networkhexa (clat on linux when)I haven't seen anyone ask for the last two tbh23:34:12
@hexa:lossy.networkhexa (clat on linux when)https://github.com/NixOS/nixpkgs/issues/23815923:34:35
@hexa:lossy.networkhexa (clat on linux when)oh, someone requested ifupdown-ng, my mistake 🙂 23:34:43
