    P2P network based on LibP2P 6 天 left
    已验证

    Hello, The project is about building a decentralized P2P network (platform) based on the IPFS or libp2p network framework. The project has 7 main phases: 1) Build a P2P network, where each node/peer participating in this network must be capable of discovering, routing, messaging, file sharing, and pinging other nodes/peers. This can be done through the IPFS or LİBP2P. This step is very easy you just need to install one of the above-mentioned protocols and then deploy it as a private (isolated) network via "Swarm / DHT". 2) Setup a VPN based on hyperspace to enable Master and Worker nodes be accessible in RAY (if you can manage it through libp2p then this task can be skipped). 3) Resource management: each node/peer must be able to manage its resources (i.e. RAM, CPU, and storage)....

    I am getting 502 Proxy Errors in my AWS Web application. I think if I increase the ProxyTimeout it will mitigate this. AWS supports a .ebextensions folder. I believe I can use that. I need to know what to name the .config file and the namespace for the option.

I am not in need for a lot of harddrive space. Now windows server 2022 is running at the slowest1TB HDD. The two faster 600 GB HDD is not in use at all, no array created. I would prefer to run Windows at the faster SSD, not at all in the server at the moment. If no good solution, the two 600 GB HDD that is faster would at least be better to use for windows? In both cases use any of the other HDD as backup and storage if needed in future. I need consulation and recommendation how to do the best setup. And then we now best setup, I need clear instructions how...
