clatd 在按这个流程建立的 archlinux 里不稳定，现在已经找出原因是因为 systemd-networkd 自动重启的时候会添加一个 default 路由。造成跟 clatd 添加的 default 路由冲突。

找到 systemd-networkd 的设置文件后，我这里是：
/run/systemd/network/10-netplan-eth0.network

在 DHCP 项下面添加一行 UseRoutes=false

保存，重启。

我感覺應該直接問 ChatGPT 就有回答了

@tyzandhr 入岛也未必保险啊，听过绿岛小夜曲吗

先整理 clatd 的安装过程 https://github.com/zazitufu/scripts/issues/7

@yunyuyuan 我找到解决方法，还有解决 clatd 不稳定的方法了。晚点整理一下发上来。

@yunyuyuan 你好，巴黎的开了 4 天终于开出来了。但是按照教程使用 clatd 时，启动这个服务之后显示以下内容：

=======================

请问这是我哪里没有作对吗？

另外就是请教一下，我这边在机器上，经常过一段时间，估计大半天左右把，然后 curl -4 google.com 就没反应了。然后重启一次 clatd 服务又可以了。有可能是在什么地方出错了吗？

@yunyuyuan 那现在应该在哪里加呢？请指点一下，谢谢。

我这边的弄的阿姆斯特丹的，cloudflare tunnel 经常掉线。查看日志是显示

我现在用 cloudflare tunnel ,在旧金山的千兆家宽上（上下速率对等）装了个 v2ray 。

但是速度很迷惑，广东电信用 v2rayN ，直连的话 10Mbps ，使用 cloudflare tunnel 的话，有时跟直连差不多，有时能到近 300Mbps （ speedtest.net)。感觉速度不稳定。

请教各位使用 tunnel 的连接速度是否都比较稳定（不管速度高低，只说稳定）？
