These are PlanetLab nodes, as their PTR record shows.  Still, there's
probably a research group behind this as PlanetLab access is limited to
those who contribute nodes, which are mostly companies and universities.

Yes, a reasonable guess given that they all signed up for the HSDir
flag.  Let's keep an eye on them.

Re: [tor-relays] DDOS

Now trying the TCP plugin in Munin...
It looks like useful to watch later/archive on a graph all TCP
connections.
Not 100% logging those attacks, but if those bad guys are using TCP
I think it will be shown here...
Here an example on my relay, graph activated ~24h ago :

  Hey,

Little noob question inside :)
If possible to learn quickly how to detect a DDOS attack ?

I got Munin running behind, can it be useful with the "netstat" and
"firewall throughput" plugins graphs to see it ?
So if the server is attacked, I think it will show some big spikes in
those graphs...?

Thx ;)

ps: I'll try to find some things about this subject, np!

[tor-relays] 8 universities doing joint HS research? (2016-06-12)

[nusenu]

This looks interesting, 8 new relays joined together:

"hsde" => hidden service discovery?

[tor-relays] Tor-arm

[NotRandom Someone]

Hi everyone,

I have a question about monitoring a tor middle relay.
What do you think about using tor-arm ?
Is it safe ? (Bugs, leaks,etc) ?
Or using just the informations on globe/atlas.torproject.org is more useful
?

Thank you.
