Explanation on handling DNS
  • I considered CNAME, but that is like multiple lookups for loading a single connection. I think this should be the option if it won't resolve directly.

    I need to look into the funnel and serve. Serve looks more close to what I'm trying to achieve. Thanks for the help.

  • Explanation on handling DNS

    I'm looking into ways to access my home network which is behind a CGNAT. Tailscale looks like the best solution so far. I would like to clarify a doubt on Tailscale

    I have a domain name registered with one of the popular services out there. I saw that Tailscale uses MagicDNS. But I wanted to use my personal domain. My doubt is if I want to use my custom domain with Tailscale, the following will be the procedure,

    1. Setup Tailscale account and add machines.
    2. My device inside the home network will get a Tailscale IP assigned. From 100.xx.xx.xx pool
    3. Use this IP to configure an A record in my Domain registrar.

    Now when I try to access this domain what will happen is,

    1. DNS server will resolve the Tailscale IP.
    2. The outside client will try to connect to my machine in the home network.
    3. Tailscale takes care of the CGNAT part and helps to establish a direct connection.
    4. Clients will use the public keys to establish trust and will communicate with each other.

    If there is anything wrong in my understanding please correct me. I could not get a clear cut answer on this through searching.

    Looking to build my first PC in almost 30 years; What should I be on the look out for?
  • I went through the comments briefly and didn't see anything about cases. I highly recommend spending some money on a good case with good cable management slots. It may not look important but it will make life so much easier. Fractal cases are good budget friendly ones. I usually prefer large bulky cases (I like ATX), to ensure good ventilation and easiness to assemble things. Having plenty of space to move around helps a lot while cleaning also.

    Another thing, you will see a lot of articles about positive pressure or negative pressure fan arrangement and all. TBH, I really don't think that matters a lot. Just regular cleaning with a cheap rocket air blower will do. And more than 4 fans are not really needed. The gain is negligible. But ensure you have a good dedicated fan/water cooling for CPU cooling. I recommend Noctua for air cooling.

    Oh regarding backing up your data, make sure you plug in your SSD once in a while, to avoid charge depletion. Nowadays the claim is SSDs have better retention and you don't need to keep it active, but I'm not really sure.

  • Seeking Linux-Friendly SCADA for Wastewater Treatment Automation
  • Offtopic question. Are you familiar with AVEVA (Wonderware) System Platform? We have been working on it for smart city command and control centre. The challenge is bringing in equipments from different OEMs under a single interface. Some projects want this to simplify operations. They prefer one application over many. What

    Another thing is I saw you specified some OEMs. And most of the time they have some variant of an open protocol that only works with their PLC. Why does the SCADA/Automation not move into some universal standards? Is it because very few OEMs have significant market share? I am aware of OPC UA. But no universal support.
