Debian 12 install Flatpak 和 Localsend

首先，LocalSend （官网，代码仓库：GitHub，CodeBerg） 是个 Gtk 应用，只能在 GUI 环境下运行；如果系统运行了 X Window System（本地和远程的都可以，通过 DISPLAY 环境变量设置 xServer），也可以通过 CLI 启动命令运行，然后启动 GUI 窗口，安装和运行步骤如下：

  1. 安装和配置 Flatpak
# Debian 12 配置 Flatpak
# 其它 Linux 发行版请参考 [设置 Flathub | Flathub](https://flathub.org/zh-Hans/setup)
apt install flatpak
# 中国大陆这一步需要代理
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
# 设置 flathub 使用“上海交通大学 Linux 用户组 软件源镜像服务”
flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub

为了测试边缘负载均衡的限流策略，需要灵活的调整真实服务器的 TPS，把 Nginx 配置成一个假负载，可以通过 url 参数 s 传值给 ngx.sleep() 控制后端的响应时间。测试方式：curl http://localhost:80/mock/sleep?s=2
server {
listen 80 backlog=4096 reuseport;
server_name localhost;
index index.html;
root /opt/case/null/;
access_log off;
location /status {
stub_status on;
allow 127.0.0.1;

解决 VirtualBox NAT 网络（Network Address Translation Service）不工作

首先我通过「全局设定」新建了一个 NAT 网络，配置如下：

[terry@imtz.tm:~] [二 8月 23 - 23:32:41]
456 => $ VBoxManage list natnetworks
NetworkName:    NatNetwork
IP:             10.0.2.1
Network:        10.0.2.0/24
IPv6 Enabled:   No
IPv6 Prefix:    fd17:625c:f037:2::/64
