  • You aren’t giving us enough information to even speculate the answer. Are these Enterprise grade servers in a datacenter? Are these home made servers with consumer or low grade hardware you’re calling servers? Are they in the same datacenter or do they go out to the Internet? What exists between the hops on the network? Is the latency consistent? What is the quality of both sides of the connection? Fiber? Wi-Fi? Mobile? Satellite?

    Does it drop too nothing or just settle into a constant slower speed? What have you tried to trouble shoot? Is it only rsync or do other tests between the hosts show the same behavior?

    Give us more and you might get some help. If these hosts are Linux I would start with iperf to do a more scientific test. And report to us some more info.


  • Yeah the previous bypass used a certificate that you’d have to authenticate periodically via 802.1x. This new method does not have that requirement. Just need the specialized hardware for it, like that Azores d20 box or one of the SFP+ xgs-pon modules that you can program.

    I’ve been using it without any intervention for a little over a 8 months now. Even have my /29 static IP block allocated on it, while still being able to also use the DHCP address they give out. You get to use the whole /29 too without the att box stealing one of them as well.





  • I don’t believe this is possible and actively protected against in the dht protocol implementation.

    The return value for a query for peers includes an opaque value known as the “token.” For a node to announce that its controlling peer is downloading a torrent, it must present the token received from the same queried node in a recent query for peers. When a node attempts to “announce” a torrent, the queried node checks the token against the querying node’s IP address. This is to prevent malicious hosts from signing up other hosts for torrents. Since the token is merely returned by the querying node to the same node it received the token from, the implementation is not defined. Tokens must be accepted for a reasonable amount of time after they have been distributed. The BitTorrent implementation uses the SHA1 hash of the IP address concatenated onto a secret that changes every five minutes and tokens up to ten minutes old are accepted.

    I believe you would have to know the torrent first, then you could discover other nodes. This is probably why that tool can’t tell you anything outside of it’s known list of torrents.

  • I’m going on 25+ years and at principal eng/architect level. My take would be to find something, try it, and find if it excites you. There isn’t a wrong answer. At worst you’ll become a generalist, fluent with more and more until you find a niche in an array of things you’re conversant in. At best you’ll dive deep into a specific area and become more and more of an expert on a topic.

    Right now I’m really into rust, rewriting tons I’ve done in the past with more experience under my belt, and learning more about web assembly. Running rust in web assembly on any platform including the user’s browser without really having to think about distribution targets is something that excites me. I think I can gleam a future that might compete with how revolutionary kubernetes has been, but even if I’m wrong the things I’ve learned will still hold up.

    If the huge array of things overwhelms you, find a problem and try to solve it. Just the act of doing that and heading into that rabbit hole can open up new worlds you never even knew existed, and helps strengthen one of what I would consider the best qualities in good devs: competent independent troubleshooting. The fun I’ve had trying my hand at bypassing att router restrictions, extracting certificates from roms, architecting my home network with self hosted kubernetes and all the home automation stuff, low level c embedded systems programming for homemade iot sensors… The things you can do with tech is usually always in reach of anyone with some time and an Internet connection.

    Also, don’t neglect the open source community. Start a project, contribute to someone else’s… Probably the biggest leap I took as a dev consisted of a simple change to a large oss project. The mentality, guardrails, rule self imposed on the project we’re incredibly impressive to me and I learned so much about the benefits of code quality, good review, automated, well everything, really opened my eyes to what a small team can do given a common goal they are passionate about, something that at times can be missing from enterprises that might have profit as king.

    Let us know what you end up at. You never know if you might inspire another dozen people with something that interests you. Good luck!
