what say the logfile ?
yes youcan allways switch to linux, but you have a interresting setup.

If you manage to pass 70Mbps of Tor traffic through your Raspberry Pi
Zero... You are definitively better at tweaking it than I am :-]

I'd say it is not fast enough for Tor, we did some tests with a
Raspberry Pi4 lately, these can utilize close to 100 MBit/s.

You could just try it, the Debian repository should provide the correct
version for the processor architecture used in Raspberry Pi. Maybe the
Tor version from the Raspbian repo is outdated.

Hey,

He is referring to the cpu not being fast enough it can’t make all the 
calculations needed to run TOR fast enough. We are referring to the base clock 
not your internet speed

Thanks,
John Csuti

100Mbps used by Tor connections? Or what kind of test did you perform
and how?

[tor-relays] Please help us find a working alternative to using MaxMind's GeoLite2 databases

[Karsten Loesing]

Hi relay operators,

as you might have heard, MaxMind has changed access and use of their
GeoLite2 databases:

https://blog.maxmind.com/2019/12/18/significant-changes-to-accessing-and-using-geolite2-databases/

This affects Onionoo and tor, and I'm trying to find a working
alternative on the following ticket:

https://trac.torproject.org/projects/tor/ticket/32978

Today I think I found a possible alternative by using data from another
provider. But before I name it here, I'd first want to find out how
accurate it is.

I tried resolving relay IP addresses of relays that have been running in
the past week and compared that to our existing lookups using MaxMind's
October database.

The result is that 7669 relays (93%) had the same country code and ASN.

I put the remaining 7% on the following wiki page:

https://trac.torproject.org/projects/tor/wiki/doc/MetricsGeoipComparison

I'd like to hear from you which data source is right and which is wrong
(or if both are wrong).

If you'd like to help, please leave comments on the ticket or in the
"Comment" column on that wiki page by February 19, 2020.

Thanks for helping!

All the best,
Karsten

[nusenu]

since 
https://trac.torproject.org/projects/tor/ticket/26585
didn't make any progress since a long time I'm glad to see 
planed improvements in this area.

some of the relays in that table actually changed their ASN location
between the last maxmind update (Oct 2019) and now
(all ASMK relays).

[Tim Niemeyer]

Hi Karsten

For the RIPE Region (the resources from RIPE) the correct source is the RIPE 
Database. There is an "country" attribute on the inetnum and inetnum6 objects.

Last time I checked maxmind, it was completely wrong about 185.220.100.0/22. I 
reported to them, but didn't get any response. And it looks as they didn't 
update since then.

I will check your list for the 185.220.100.0/22 prefixes and report in the 
ticket, later.

Tim

[niftybunny]

Sorry for the reply here. I am in an endless cycle of:

Trac thinks your submission might be Spam. To prove otherwise please provide a 
response to the following.


and capture solving does not really work.

Checking my relays its hard to tell what is correct. As a German IXC I do own 
the IPs but the servers are in the Netherlands. If you prefer the ownership of 
the IPs Maxmind is correct with Germany, if you prefer where the actual servers 
are the new one is correct. Pick your poison :) At least the new one has my new 
AS, so I am a happy bunny after all.

There are often at least 2 correct answers for GeoIP, sometimes more:
* the physical location of the server,
* the business address of the data centre operator,
* the business address of the owner or reseller of the server.

Some servers and businesses have layers of owner/operator/reseller/
corporate subsidiaries, so it can get very complicated.

I once operated relays that were obviously in Australia (because of
the traceroute and latency), but were geolocated to the US, because
their reseller was in the US.
