I just set the 'moderated' bit on this person, so further messages (after
these two) will need manual attention before they make it to the list.

Hopefully that will keep the signal-to-noise ratio on the right side
of the line. :)

Sorry for the troubles,

I mean for the safety of users. IPv6 is usually a /64 network and the
various IPv4 are usually also from a subnet.


Answer #1: if they're using different IP addresses, sure, go for it.


Different IP are a must, that's clear anyway.

But...
Normally you get from the provider:
some IPv4 fron same subnet:
203.0.113.111
203.0.113.222
203.0.113.333

and one IPv6 Prefix:
2001:0DB8:123:456::/64


After reading that from your link below, I realize it's a bad idea to 
use similar IP's for Bridge and Gateway.


I came up with the idea, because my server still has a lot of resources 
available. But I do not have traffic anymore. 2 Tor instaces consume all 
my 20TB.

Thanks. That's exactly the stuff I'm looking for. ;-)

[tor-relays] New Relay: ShawnWebb01

2019-03-22 Thread Shawn Webb
Hey all,

A few days ago, I put up a new relay on a PC Engines device running
HardenedBSD 13-CURRENt/amd64:

https://metrics.torproject.org/rs.html#details/57869F7458002476F6AC78F7A61C960CBA94497F

I should update ContactInfo soon to reflect the ContactInfo format
nusenu would like relays to use.

IPv4 address of the relay comes from Verizon FiOS and IPv6 comes from
Hurricane Electric's TunnelBroker.

Please let me know if you have any questions, comments, or concerns.

Thanks,

Which means, to avoid few attack vector, a Tor relay operator might run a 
bridge which points to its own relay always?

Answer #1: if they're using different IP addresses, sure, go for it.

Answer #2: if they're using the same IP address, you can do it
technically, but it's probably not a good move.

Some years ago, it used to be that China blocked Tor relays and bridges
by blocking the particular IP:port they listened on.

But in the past year or two, they switched to just blackholing the IP
address if there's a Tor thing on it.

So, that means when they learn the relay IP address and blackhole it,
if your bridge is on that same IP address, the bridge becomes unreachable
too. Not the best outcome.

And, while you're thinking about bridge blocking, here are many other
angles to learn about:

Hope that helps,
