Hi, I would like to share with the community some tests I've made for setting up a "swarm" of Tor relays.

I setted up 3 exit relays and 3 middle relays on the same IPv4 address, to make some testing, and the entire swarm works like a charm.

Due to Tor limitation, I have decided to build a template for preparing the cluster, and upload it to GitHub.

You can find the example mini-cluster here: https://github.com/randomtable/ChimeraOS/tree/master/TorSwarm

I have tested the exit capabilities on another network with different public IP address.

All the relays have published their own descriptors, I have prepared the containers as a single, separated machines.

The process is different from preparing a single relay, because of Docker build process.

I have disabled caching during the cluster process, so i have been able to modify torrc without issues.

Because its very interesting, attached to this e-mail there is the console Logs from the 6 relays.

All containers are read-only, so the entire relay will destroy at the end of session.

I hope this can be useful.

Hi,

The concept of a "Relay swarm" is to have multiple running relay

containers on the same user machine, without any conflict.

The idea (i will testing it very soon) is possible, by pulling an image

and running it multiple times, creating intermetiate containers.

A function like the "relay swarm" can be very useful, i don't know if

this approach can be risky, so i'm preparing a script for launching only one type of relay swarm (middle or exit relays).

...

If there is no security concerns, this function will be a very key

function for grow up the Network, because a user can run multiple relays at a time.

Tor only allows 2 relays per IPv4 address.
