Re: [tor-relays] TCP CCA for Tor Relays (and especially Bridges)

Matt You can find a nice compare between loss less and loss based congestion here [1]. It's difficult to say if one or the other are better in the use with Tor. A single TCP connection between two Tor relays bundles multiple circuits (data flows) which can result in very different needs for congestion to connect end points.

I never tried this, but have a look at "EntryNodes node,node,…" here: https://2019.www.torproject.org/docs/tor-manual.html.en Or look at "UseBridges 0|1" and "Bridge [transport] IP:ORPort [fingerprint]".

There is a release trac here: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases Did you check how to add the official sources for Debian based/like systems, there is some info here: https://2019.www.torproject.org/docs/debian.html.en > > 3.

There is some descriptions like that in the Internet, but I'd advice against this, you see a lot of captures when only using Tor. But there is some guides to setup a Raspberry to act as a Tor router that does not allow traffic to take any other route. > > 4. What kind of low-budget servers (-100€), i can buy for running ≈12MB/s > Relays ? From what I heard lately a Raspberry Pi 3B won't work, it will not have sufficient CPU power, also a Pi4 seems to be a bit short in CPU power, but I'd say something with a bit more power should be able to take 12MByte/s.

Re: [tor-relays] %include in torrc
Thanks for correcting my false assumption, I assumed the application is just still called arm, but now I see the application is really outdated. I wonder why it is not maintained in the Debian sources. But well, the packages are sometime outdated. Thanks for now. yl On 1/8/20 12:42 AM, Damian Johnson wrote: > Hi yl, arm and nyx's author here.
