Considering there are potential critical failures when the IPv6 ORPort is configured, should the relay guide suggest the operator confirm they have IPv6 connectivity to all of the IPv6-enabled directory authorities[2] before enabling it ("Please ping6/telnet/nc to these hosts before enabling this.")?
thanks for this suggestion, I hope you like the change: https://trac.torproject.org/projects/tor/wiki/TorRelayGuide?action=diff&vers...
It would also be nice if the relay, itself, performed self-checks of this connectivity and printed a warning log if some failure-threshold is reached (and possibly disabling the IPv6 ORPort). But, in reality, this is a hack
I wouldn't call it a 'hack', I'd consider it a reliability feature. -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
