Sorry if I haven’t posted anything here, but all the work has been done in public: Firewall: Remove the button of speedtest-cli · Issue #6588 · NethServer/dev · GitHub.
There is no real replacement, but a bunch of alternatives for various cases:
- speedtest-cli (already bundled in NS) is good for connections with a maximum download speed of 500Mbit/s
- librespeed is much better than speedtest-cli for fast connections but the result heavily depends on the selected remote server
- ookla is a closed-source and non-redistributable alternative, which is almost the de-facto standard
After selecting your preferred speedtest binary, execute as:
fireqos stop
<your_speedtest_binary>
fireqos start
