> If you have a VPS spare bandwidth, I encourage you to set up a relay, too. It is very easy to do and a great way to contribute to the Tor project. I run three relays right now. I agree that it's pretty easy to setup, especially on Ubuntu, but the documentation could really use improvement. It makes it sound much harder to setup than it actually is. To anyone who is thinking of running a relay, here are the basic steps: 1. Add the Tor repo to your package manager [1] 2. Install Tor 3. Edit the config file to set a name, your contact info, bandwidth limit, and exit policy. This is all pretty well documented in the config file. 4. Start Tor (eg `sudo service tor start`) If you want to run an exit node you should read the Tor docs about the topic and decide which ports to open.[2][3] 1: https://www.torproject.org/download/download-unix.html.en https://www.torproject.org/download/download-unix.html.en 2: https://trac.torproject.org/projects/tor/wiki//doc/TorExitGuidelines https://trac.torproject.org/projects/tor/wiki//doc/TorExitGu... 3: https://blog.torproject.org/blog/tips-running-exit-node-minimal-harassment https://blog.torproject.org/blog/tips-running-exit-node-mini...

I see also that there are some tor relay Docker containers out there, e.g. https://github.com/vpetersson/docker-torrelay https://github.com/vpetersson/docker-torrelay I also quite like Tor Arm if you are running a relay, for an nice eye-candy dashboard: https://www.torproject.org/projects/arm.html.en https://www.torproject.org/projects/arm.html.en

It's good practice to discuss plans with your hosting provider, so that you and they both know what to expect. Stealth doesn't cut it, especially if there's real money at risk. Also, keep in mind that relay IPs, and perhaps even subnets, may show up on various blacklists. Other services (perhaps those of other hosting customers) may be affected.

  > keep in mind that relay IPs, and perhaps even subnets, may show up on various blacklists Have you got an example of that? I know a few relays intimately and I've never seen this.

    Numerous sites pull down lists of exits daily/hourly/$xly and retroactively block them, although I've never heard of a subnet being blocked.

    I recall seeing this on tor-talk or tor-relays within the past year or so. Someone started running an exit, and their hosting provider nuked their account, claiming that other customers were being affected by bans. I'll see if I can find it. Edit: Here's one example, posted by Zack Weinberg on the tor-relays list.[0] CMU network operations has decided to move the Tor exit node that my group operates (tor-exit.cylab.cmu.edu) to an isolated subnet in order to minimize consequences for the rest of the campus network. For instance, apparently there have been several cases where third parties blacklisted the entire CMU IP space in response to malicious traffic from the exit node. This is currently scheduled to happen Tuesday (Nov. 4). The new IP address will be 204.194.29.4.

      Note that a tor exit node is quite different from a relay.
    - xorcist 12y ago
      It is quite expected if you run an exit node. However this was in regard to a relay node, which is something else entirely. I've seen a few references to these supposed problems with running a relay nodes lately, but the poster never replies with any information where this have actually happened. This behaviour is new. It wouldn't surprise me if it's coordinated, considering what else we've seen lately.

  This primarily applies to exits, not relays. Relays only work within the Tor network and never know exactly what they're relaying.

    Some sites don't bother distinguishing between relays and exits. They just block non-Tor access from all Tor node IPs.
