-tags go.net.trace
flag enables the trace function to generate detailed trace data containing function calls, return values ??and stack trace information to help pinpoint problems.
4. Network diagnostic tools
- netshoot: Although netshoot is mainly used for container network diagnosis, it is also suitable for Debian systems. After installing netshoot, you can access a range of powerful network diagnostic tools, such as
tcpdump
andnetstat
