/ip firewall address-list add list=blacklist address=xxx.xxx.xxx.xxx/24
/ip firewall address-list add list=blacklist address=xxx.xxx.xxx.xxx-xxx.xxx.xxx.xxx

設定 raw:
/ip firewall raw add chain=prerouting action=drop src-address-list=blacklist

匯出 address list:
/ip firewall address-list export

目前的封鎖清單: (烏克蘭SpaceshipNetworks持續不斷, 持續封鎖)

樹莓派安裝執行 .NET Core 程式

參考影片: https://www.youtube.com/watch?v=WDlZ3f2xHcc

先安裝 visual studio code:
sudo apt install code

建立公用目錄:
sudo mkdir /usr/share/dotnet

先看微軟網頁 https://dotnet.microsoft.com/zh-cn/download/dotnet/6.0, 找到下載 ARM32 (或64) 版本的連結, 然後用 wget 下載:

sudo wget https://download.visualstudio.microsoft.com/download/pr/e41a177d-9f0b-4afe-97a4-53587cd89d00/c2c897aa6442d49c1d2d86abb23c20b2/dotnet-sdk-6.0.202-linux-arm.tar.gz

或是5.0版:

wget https://download.visualstudio.microsoft.com/download/pr/17588888-bd97-41e6-a1ef-9f1da6b8bdf6/ab16a7b0b82297f76abc793b5d187952/dotnet-sdk-5.0.407-linux-arm.tar.gz

解開至公用目錄:
sudo tar zxvf dotnet-sdk-6.0.202-linux-arm.tar.gz -C /usr/share/dotnet

或是5.0版:

sudo tar zxvf dotnet-sdk-5.0.407-linux-arm.tar.gz -C /usr/share/dotnet

 
編輯 ~/.profile, 在最後增加 export 設定:
export PATH=$PATH:/usr/share/dotnet
export DOTNET_ROOT=/usr/share/dotnet

重新登入讓 profile 生效

建立 .net 專案
cd ~
mkdir hello

建立 console 專案:
cd hello
dotnet new console
這時會在目錄下產生 .csproj 與 Program.cs 等專案檔

編譯:
dotnet build

執行:
./bin/Debug/net6.0/hello

dotnet支援的專案類型:
dotnet new -l

ESP-IDF 使用 ESP32-S2 的設定/編譯/燒錄

有個 HMI OS 的構想, 買了一片 ESP32-S2-Kaluga-1 Kit 來用, 這片是 ESP32-S2, ES_IDF 預設是 ESP32, 如果沒有設定 target, 編譯後無法上傳. 紀錄一下設定/編譯/燒錄的指令:

 

進入 example project 目錄後 (例如 C:\Espressif\frameworks\esp-idf-v4.4.1\examples\get-started\blink) :

設定: idf.py set-target ESP32-S2

編譯: idf.py build

燒錄的指令 idf.py -p COMx flash
