[tor-relays] bug message from 02/28/2020 on 4.5.6

[William Kane]

Hi Matt,

this is non fatal and as you can see by the most recent log entries,
you could ignore it - anyway, some contributor warned about this
occurring with more recent tor builds since the way tor probes for
listening sockets has changed / it now always binds to all IPv4 &
IPv6 addresses and then does reachability checks for each?

It was something along the lines of that.

What if you manually specify your listening IP addresses and port like I do:

ORPort 37.157.195.83:38619
ORPort [2a02:2b88:2:1::3239:0]:38619

This should satisfy tor, at least it does on 0.4.4.6 which is the
newest version available through the official ArchLinux repositories,
not sure about 0.4.5.x branch which states the following in it's
change log:

This release series introduces significant improvements in relay
(IPv6) address discovery.

That would be much safer and cleaner than tor trying to guess which
addresses it's supposed to bind to anyway :-)

Thank you for running a relay!

Best Regards,
William
