How to record Log.

[ChenKitDon]

I use the iper.exe tool, but after running for a while, it will crash by itself. How to record the LOG of this problem, and I want to analyze where the LOG problem is.
System: win11

Usually, logs are not sufficient to analyze crashes, and using tools like gdb is needed.

In any case, what is the iperf version? Can you run iperf.exe -v and share the output?

[ChenKitDon]

The version is 2.0.5,Can you provide the gdb tool?

GDB can be found here: https://www.sourceware.org/gdb/

I'm going to move this to a discussion, since Windows isn't officially supported.

Thank you for providing, can you provide the SOP of GDB, let me refer to how to use and analyze the problem?

The version is 2.0.5

You are using iperf2 but this issues/discussions are for iperf3. Use https://sourceforge.net/projects/iperf2/ to open iperf2 issues/discussions.

In any case, you are using a very old version of iperf2 that may not be compatible with win11. I suggest first to try downloading a newer version (probably 2.1.9) of iperf2 from https://sourceforge.net/projects/iperf2/files/. Note that both client and server should be upgraded.

Alternatively, if you planned using iperf3, a Windows version can be downloaded from https://files.budman.pw/ (not an official site). Also, iperf2 and iperf3 are not compatible, so both server and client should be either iperf2 or iperf3.
