Re: [tor-relays] BadExit

[<gerard@xxxxxxxxxxxx>]

Thanks.  Funny that my long time restricted IPv4 port 80 exit was noticed just now giving the bad exit tag.   I suspect the hour one of my  server was quarantined by my ISP may have precipitated the system to look hard.

As for my single /8 for port 80, for reason not clear to me, having many ports open including 443 open to all, IPV6 open on port 80 to all, while restricting IPV4 to a single /8 stops all abuse complaints.  I have been free of abuse complaints and copyright claims for two years now.   I tried to offer more IPv4 /8 ranges but abuses notices soon popped up, as if traffic is being en-route by some agencies.   The free-text nature of port 80 meant contents read too easily, and IPV6 still not used enough... yet.

Yep, I think that's what happened. I'll get the badexit flag removed from both of your relays and think about ways for improving our tests.
Sorry for the inconvenience.

(FWIW: I sent an email to the address you put into your ContactInfo. I heard that mails for Tor Project addresses repeatedly land in spam folders. Maybe that happened this time, too.)

Not sure what Arthur is running but I am just using what Debian ships on the box I run the tests, which is currently 0.3.5.8. I guess it might be worth thinking about switching away from that. Maybe tracking and using the version Tor Browser ships is smarter?
