IP address in #Debian #trixie not what you expected?

Edit /etc/dhcpcd.conf and look for the block “Generate SLAAC address” near the end; comment out slaac private and uncomment slaac hwaddr.

#FYI #PSA #IPv6 #IP #SLAAC #rtsol #rtadvd #radvd

#IPv6 (zumindest via #radvd) ist bei uns nun temporär deaktiviert wegen #MTU Problemen, scheinbar zu diversen #Microsoft Seiten/Diensten. Dies macht sich dadurch bemerkbar, dass insbesondere größere Dateien/Seiteninhalte hier nicht geladen werden. Zur Zeit sieht es für uns aus, als ob sich #Microsoft nicht an IPv6-Standards hält (und insbesondere ICMPv6 Packet Too Big Nachrichten unkorrekterweise ignoriert). Aber wir sind da dran, das zu klären.

Jetzt nur über IPv4 sollte es aber vorerst gehen.

Is it just me or is #radvd "::/64" prefix autodiscovery broken since it doesn't limit the prefix length to 64? If the ISP offers a wider than 64-bit block the autodiscovery will just pick that value as-is and advertise it. At least macOS and iOS will reject such overly wide RA.

One fix for this is to just use explicit prefix stanza with "address::/64" but this requires that the radvd.conf is generated runtime based on the prefix obtained from the ISP.

Since I didn't feel like having to keep regenerating the radvd.conf dynamically I just patched the send.c to limit the xprefix.PrefixLen to 64.

I'm sure there's a better way but this problem looked like a nail to me.

#IPv6 #SLAAC

someone here got #zerotier running with a bridge and 6pane network inside of that?
I already have #radvd advertising the route, but #kea #dhcpv6 seems not to work or the client does not do dhcpv6...

Perhaps i should just try #isc-dhcpv6 🙄
