ArenlorAnyone here using systemd? I'm having trouble with ipv6 [15:30]
JC_Dentonregrettably, yes [15:36]
ArenlorI can't seem to figure out why it doesn't want to talk to the gateway with networkd [15:39]
JC_Dentonwhat distro? [15:40]
ArenlorArch
Using traceroute I get this: https://ptpb.pw/DKRb
[15:40]
JC_Dentonwhat's in your /etc/systemd/network dir
i'll admit i have not used systemd-networkd in particular
[15:48]
ArenlorA single file: eth0.network which is https://ptpb.pw/pjMn [15:50]
JC_Dentoni believe your gateway is wrong
check your ip space page on portal for the right gateway, but it's probably fe80::1
[15:53]
ArenlorIt lists it as 2607:f2f8:3180::1 on the portal. [15:55]
JC_Dentoncan you ping6 it? [15:56]
ArenlorNope: https://ptpb.pw/xdIH [15:57]
JC_Dentondoes it look ok in "ip addr show" [16:11]
ArenlorI think so: https://ptpb.pw/Z-Ng [16:12]
***ziyourenxiang has quit IRC (Ping timeout: 252 seconds) [16:23]
JC_Dentonhrm, /proc/sys/net/ipv6/conf/eth0/disable_ipv6 isn't 1 by chance? [16:28]
ArenlorNope, it's 0. [16:29]
JC_Dentonwhat's "ip -6 route" look like? [16:30]
ArenlorNothing I know how to interprate https://ptpb.pw/GiPq [16:33]
***KILLALLHUMANS01 has joined #arpnetworks [16:43]
JC_Dentoni'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
[16:44]
ArenlorYep: RTNETLINK answers: File exists [16:46]
JC_Dentoncan you ping6 fe80::1%eth0 ? [16:47]
ArenlorNo [16:49]
JC_Dentondoes it work at all w/o networkd? [16:56]
ArenlorHaven't tried that, what networking software do you suggest using? [16:57]
JC_Dentoni 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? [16:58]
Arenlorhttps://ptpb.pw/yITw
No idea how ti interprate that neither, but it does not look right.
[16:59]
JC_Dentonhow much v6 space do you have? just the single /64 or did you get the /48? [17:08]
ArenlorJust the /64, I have no need for the /48, I doubt I'll ever be able to think of uses for the /64 [17:09]
JC_Dentontry 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.
[17:11]
ArenlorIt's working better: https://ptpb.pw/0HTG
Still not routing correctly though: https://ptpb.pw/4TPS
[17:14]
JC_Dentoncan you ping6 ipv6.google.com? [17:17]
ArenlorNope, destination unreachable. [17:19]
JC_Dentonwhat's your network file look like now? [17:22]
Arenlorhttps://ptpb.pw/GxKy [17:23]
JC_Dentonand ip route -6? [17:27]
ArenlorLooks the same: https://ptpb.pw/GiPq [17:27]
JC_Dentonbut you can ping the gateway now
odd
[17:29]
ArenlorYeah, I know.
Been dealing with this weirdness for two days now.
[17:30]
JC_Dentonyeah, i'd disable networkd and configure manually and attempt to replicate [17:32]
ArenlorWill have to do, thanks! [17:33]
JC_DentonArenlor: 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
[17:34]
ArenlorManually does not seem to have worked neither. I wonder if it's something weird not setup correctly outside the thunder vm? [17:43]
...... (idle for 26mn)
JC_Dentonwhat does "ip -6 addr show" and "ip -6 route show" [18:09]
Arenloraddr: https://ptpb.pw/sCc8 route: https://ptpb.pw/YTtm [18:17]
JC_Dentonyou 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
[18:27]
........ (idle for 39mn)
ArenlorStudiply that worked... [19:06]
JC_Dentonsystemd sucks [19:11]
ArenlorYeah, it's not super friendly, some of it seems to be just randomly cobbled together from other ideas (not even full projects). [19:13]
JC_Dentonit's like the Borg, assimilating itself into an unstoppable cube [19:18]
................. (idle for 1h22mn)
***Arenlor has left [20:40]
