Arenlor has joined #arpnetworks Arenlor: Anyone here using systemd? I'm having trouble with ipv6 JC_Denton: regrettably, yes Arenlor: I can't seem to figure out why it doesn't want to talk to the gateway with networkd JC_Denton: what distro? Arenlor: Arch
Using traceroute I get this: https://ptpb.pw/DKRb JC_Denton: what's in your /etc/systemd/network dir
i'll admit i have not used systemd-networkd in particular Arenlor: A single file: eth0.network which is https://ptpb.pw/pjMn JC_Denton: i believe your gateway is wrong
check your ip space page on portal for the right gateway, but it's probably fe80::1 Arenlor: It lists it as 2607:f2f8:3180::1 on the portal. JC_Denton: can you ping6 it? Arenlor: Nope: https://ptpb.pw/xdIH JC_Denton: does it look ok in "ip addr show" Arenlor: I think so: https://ptpb.pw/Z-Ng ***: ziyourenxiang has quit IRC (Ping timeout: 252 seconds) JC_Denton: hrm, /proc/sys/net/ipv6/conf/eth0/disable_ipv6 isn't 1 by chance? Arenlor: Nope, it's 0. JC_Denton: what's "ip -6 route" look like? Arenlor: Nothing I know how to interprate https://ptpb.pw/GiPq ***: KILLALLHUMANS01 has joined #arpnetworks JC_Denton: i'm surprised there's no "default via" but there are nexthop entries
what happens if you "sudo ip -6 route add default via 2607:f2f8:3180::1 dev eth0"
it'll probably complain that it exists Arenlor: Yep: RTNETLINK answers: File exists JC_Denton: can you ping6 fe80::1%eth0 ? Arenlor: No JC_Denton: does it work at all w/o networkd? Arenlor: Haven't tried that, what networking software do you suggest using? JC_Denton: i was going to suggest a manual setup to rule out systemd. but out of curiosity, what does "ip -6 route get 2607:f2f8:3180::1" yield? Arenlor: https://ptpb.pw/yITw
No idea how ti interprate that neither, but it does not look right. JC_Denton: how much v6 space do you have? just the single /64 or did you get the /48? Arenlor: Just the /64, I have no need for the /48, I doubt I'll ever be able to think of uses for the /64 JC_Denton: try scrubbing all the other addrs you have and just have ::2 and the gateway of ::1
curious if it'll work then
also get rid of that virtualization parameter. not sure what networkd does with that. Arenlor: It's working better: https://ptpb.pw/0HTG
Still not routing correctly though: https://ptpb.pw/4TPS JC_Denton: can you ping6 ipv6.google.com? Arenlor: Nope, destination unreachable. JC_Denton: what's your network file look like now? Arenlor: https://ptpb.pw/GxKy JC_Denton: and ip route -6? Arenlor: Looks the same: https://ptpb.pw/GiPq JC_Denton: but you can ping the gateway now
odd Arenlor: Yeah, I know.
Been dealing with this weirdness for two days now. JC_Denton: yeah, i'd disable networkd and configure manually and attempt to replicate Arenlor: Will have to do, thanks! JC_Denton: Arenlor: read this too: https://blog.bastelfreak.de/2016/05/doing-ipv6-with-systemd-networkd-the-correct-way/
i wonder if that's it
and if it is, it just reminds me why i hate systemd Arenlor: Manually does not seem to have worked neither. I wonder if it's something weird not setup correctly outside the thunder vm? JC_Denton: what does "ip -6 addr show" and "ip -6 route show" Arenlor: addr: https://ptpb.pw/sCc8 route: https://ptpb.pw/YTtm JC_Denton: you probably need to flush the routing table to get rid of those networkd added routes
try the suggestion in that blog posted coupled with a reboot Arenlor: Studiply that worked... JC_Denton: systemd sucks Arenlor: Yeah, it's not super friendly, some of it seems to be just randomly cobbled together from other ideas (not even full projects). JC_Denton: it's like the Borg, assimilating itself into an unstoppable cube ***: Arenlor has left
