I had an issue with my VPS that I didn't notice for a while where I had lost my IPv6 addressing. After contacting support they have restored the IPv6 address, but I'm now unable to bind to the address. I've a feeling it's more either my configuration or the VPS configuration at fault, not tor, but I thought I'd throw it out for ideas, as I'm not that confident (yet) with IPv6 stuff.
Here's the interface:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether a6:6a:08:73:42:27 brd ff:ff:ff:ff:ff:ff altname enp0s18 inet xxx.yyy.87.222/26 brd xxx.yyy.87.255 scope global eth0 valid_lft forever preferred_lft forever inet6 aaaa:bbbb:1a:10::1/64 scope global dadfailed tentative valid_lft forever preferred_lft forever inet6 fe80::a46a:8ff:fe73:4227/64 scope link valid_lft forever preferred_lft forever
root@fw1475:~# ip -6 route aaaa:bbbb:1a:10::/64 dev eth0 proto kernel metric 256 pref medium fe80::/64 dev eth0 proto kernel metric 256 pref medium default via aaaa:bbbb:1a:10:a46a:8ff:fe73:4227 dev eth0 proto static metric 1024 pref medium
And the netplan configuration:
root@fw1475:~# netplan status Online state: online DNS Addresses: 127.0.0.53 (stub) DNS Search: .
● 1: lo ethernet UNKNOWN/UP (unmanaged) MAC Address: 00:00:00:00:00:00 Addresses: 127.0.0.1/8 ::1/128
● 2: eth0 ethernet UP (networkd: eth0) MAC Address: a6:6a:08:73:42:27 (Red Hat, Inc.)

And this is what I get from the IPv6 OR port, determined by commenting/uncommenting the relevant line in my previously working configuration:
2024-12-14T20:36:38.782783+00:00 fw1475 tor[2317]: Dec 14 20:36:38.782 [warn] Failed to parse/validate config: Failed to bind one of the listener ports. 2024-12-14T20:36:38.782821+00:00 fw1475 tor[2317]: Dec 14 20:36:38.782 [err] Reading config failed--see warnings above.
Any ideas/help would be gratefully accepted.
Cheers, Eddie
