+> If you are new to NixOS and want to know how I use NixOS, I would recommend you to take a look at the [ryan4yin/nix-config/releases](https://github.com/ryan4yin/nix-config/releases) first, **checkout to some simpler older versions**, which will be much easier to understand.

+2. macOS Desktops: nix-darwin with home-manager, share the same home-manager configuration with NixOS Desktops.

 ## Why install I3/Hyprland in Home Manager instead of a NixOS Module?

    1. Make the NixOS system more secure and stable.
    2. Make this flake more portable to other non-NixOS systems, as home-manager can be installed on any Linux system.

+## How to install NixOS on Orange Pi 5 Plus
+
+### 1. Prepare a USB LUKS key
+
+Generate LUKS keyfile to encrypt the root partition, it's used by disko.
+
+```bash
+# partition the usb stick
+DEV=/dev/sdX
+parted ${DEV} -- mklabel gpt
+parted ${DEV} -- mkpart OPI5P_DSC fat32 0% 512MB
+mkfs.fat -F 32 -n OPI5P_DSC ${DEV}1
+
+# Generate a keyfile from the true random number generator
+KEYFILE=./orangepi5plus-luks-keyfile
+dd bs=512 count=64 iflag=fullblock if=/dev/random of=$KEYFILE
+
+# copy the keyfile and token to the usb stick
+KEYFILE=./orangepi5plus-luks-keyfile
+DEVICE=/dev/disk/by-label/OPI5P_DSC
+# seek=128 skip N obs-sized output blocks to avoid overwriting the filesystem header
+dd bs=512 count=64 iflag=fullblock seek=128 if=$KEYFILE of=$DEVICE
+```
+
+### 2. Partition the SSD & install NixOS via disko
+
+First, follow [UEFI - ryan4yin/nixos-rk3588](https://github.com/ryan4yin/nixos-rk3588/blob/main/UEFI.md) to install UEFI bootloader and boot into NixOS live environment via a USB stick.
+
+Then, run the following commands:
+
+```bash

-These four servers are named after the four main characters of the mange/anime Oshi no Ko, they form a NixOS distributed building cluster,
-I usually run the build command on `Ai` and nix will distribute the build to other three machines, which is convenient and fast.
+1. Under `hosts/`
+   1. Create a new folder under `hosts/` with the name of the new host.
+   2. Create & add the new host's `hardware-configuration.nix` to the new folder, and add the new host's `configuration.nix` to `hosts/<name>/default.nix`.
+   3. If the new host need to use home-manager, add its custom config into `hosts/<name>/home.nix`.
+1. Under `outputs/`
+   1. Add a new nix file named `outputs/<system-architecture>/src/<name>.nix`.
+   2. Copy the content from one of the existing host's nix file, and modify it to fit the new host.
+   3. [Optional] Add a new unit test file under `outputs/<system-architecture>/tests/<name>.nix` to test the new host's nix file.
+   4. [Optional] Add a new integration test file under `outputs/<system-architecture>/integration-tests/<name>.nix` to test whether the new host's nix config can be built and deployed correctly.

-When building some packages for riscv64 or aarch64, I often have no cache available because of various changes under the hood, so I need to build much more packages than usual, which is one of the reasons why the cluster was originally built, and another reason is distributed building is cool!

+# Idols - Aquamarine
+
+A router(IPv4 only) with a tranparent proxy to bypass the G|F|W.
+
+NOTE: dae(running on aquamarine) do not provides a http/socks5 proxy server, so a v2ray server is running on [idols_kana](../idols_kana/proxy.nix) to provides a http/socks5 proxy service.
+
+## Troubleshooting
+
+### Can not access the global internet
+
+1. Check wether the subscription url is accessible.
+   - If not, then you need to get a new subscription url and update the `dae`'s configuration.
+1. Check the `dae` service's log by `journalctl -u dae -n 1000`.
+
+### DNS cannot be resolved
+
+1. `sudo systemctl stop dae`, then try to resolve the domain name again.
+   - If it works, the problem is caused by `dae` service.
+   - check dae's log by `journalctl -u dae -n 1000`
+1. DNS & DHCP is provided by `dnsmasq` service, check the configuration of `dnsmasq`.
+
+### DHCP cannot be obtained
+
+1. `ss -tunlp`, check if `dnsmasq` is running and listening on udp port 67.
+1. `journalctl -u dnsmasq -n 1000` to check the log of `dnsmasq`.
+1. Request a new IP address by disconnect and reconnect one of your devices' wifi.
+1. `nix shell nixpkgs#dhcpdump` and then `sudo dhcpdump -i br-lan`, check if the DHCP request is received by `dnsmasq`.
+   1. The server listens on UDP port number 67, and the client listens on UDP port number 68.
+   1. DHCP operations fall into four phases:
+      1. Server **discovery**: The DHCP client broadcasts a DHCPDISCOVER message on the network subnet using the destination address 255.255.255.255 (limited broadcast) or the specific subnet broadcast address (directed broadcast).
+      1. IP lease **offer**: When a DHCP server receives a DHCPDISCOVER message from a client, which is an IP address lease request, the DHCP server reserves an IP address for the client and makes a lease offer by sending a DHCPOFFER message to the client.
+      1. IP lease **request**: In response to the DHCP offer, the client replies with a DHCPREQUEST message, broadcast to the server,[a] requesting the offered address.
+      1. IP lease **acknowledgement**: When the DHCP server receives the DHCPREQUEST message from the client, it sends a DHCPACK packet to the client, which includes the lease duration and any other configuration information that the client might have requested.
+   1. So if you see only `DISCOVER` messages, the dhsmasq is not working properly.
