This article is recommended for everyone to install this catnd, while catwrt-update is a check update script that CatWrt v23.2 has after, the previous one did not, and subsequent updates will integrate both.
catnd: Full name CatWrt-network-diagnostics, a network diagnostic script for CatWrt.
catwrt-update: Check CatWrt updates, responsible for checking if the server version information is consistent script.
This article briefly introduces the functions that everyone does not know, and the script itself is open source and very useful.
Thanks @timochan
First of all, these scripts need to be executed under SSH, without a graphical interface (LuCI), the installation is relatively simple and easy to use. Of course, you can use third-party SSH tools to connect, such as Termius or Finalshell, or the TTYD WebShell built into the router system.
Note that all scripts are in /usr/bin
