+> 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.

    1. Make the NixOS system more secure and stable.

+## 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
+# transfer the nix-config to the target machine
+rsync -avzP ~/nix-config rk@<ip-addr>:/home/rk/
+
+# login via ssh
+ssh rk@<ip-addr>
+
+cd ~/nix-config/hosts/12kingdoms_rakushun
+# 1. change the disk device path in ./disko-fs.nix to the disk you want to use
+# 2. partition & format the disk via disko
+sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko ./disko-fs.nix
+
+
+cd ~/nix-config
+# install nixos
+# NOTE: the root password you set here will be discarded when reboot
+sudo nixos-install --root /mnt --flake .#rakushun --no-root-password --show-trace --verbose
+```

+## How to install NixOS on Orange Pi 5 
+
+### 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 primary 2M 512MB
+mkfs.fat -F 32 -n OPI5_DSC ${DEV}1
+
+
+# Generate a keyfile from the true random number generator
+KEYFILE=./orangepi5-luks-keyfile
+dd bs=512 count=64 iflag=fullblock if=/dev/random of=$KEYFILE
+
+# copy the keyfile and token to the usb stick
+KEYFILE=./orangepi5-luks-keyfile
+DEVICE=/dev/disk/by-label/OPI5_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
+# login via ssh
+ssh rk@<ip-addr>
+
+git clone https://github.com/ryan4yin/nix-config.git
+
+cd ~/nix-config/hosts/12kingdoms_suzu
+# 1. change the disk device path in ./disko-fs.nix to the disk you want to use
+# 2. partition & format the disk via disko
+sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko ./disko-fs.nix
+
+
+cd ~/nix-config
+# install nixos
+# NOTE: the root password you set here will be discarded when reboot
+sudo nixos-install --root /mnt --flake .#suzu --no-root-password --show-trace --verbose
+```

 # Idols - Aquamarine

-TODO: use aqua as a passby router(IPv4 only) to access the global internet.
+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.

+I'm running two Kubernetes clusters, one for production and one for testing.
+
+I prefer to use [k3s] as the Kubernetes distribution, because it's lightweight, easy to install, and full featured(see [what-have-k3s-removed-from-upstream-kubernetes] for details).
+
+## Hosts
+
+![](/_img/2024-02-18_k8s-nodes-overview.webp)
+
+1. For production:
+   1. `k3s-prod-1-master-1`
+   1. `k3s-prod-1-master-2`
+   1. `k3s-prod-1-master-3`
+   2. `k3s-prod-1-worker-1`
+   2. `k3s-prod-1-worker-2`
+   2. `k3s-prod-1-worker-3`
+1. For testing:. 
+   1. `k3s-test-1-master-1`
+   2. `k3s-test-1-worker-1`
+   3. `k3s-test-1-worker-2`
+   4. `k3s-test-1-worker-3`
+
+## Kubernetes Resources
+
+Kubernetes resouces are deployed and managed separately through [nix-config/pulumi/k8s/](../../pulumi/k8s/).
