I though it was because of the binary name, it was iperf3 so i renamed it to iperf but it seems Flent needs iperf 2? It's the one that has --enhancedreports option.

Yup, indeed, you'll need iperf2 :)

I ran into the presumably same problem on an up to date Debian 12 "bookworm" and Ubuntu 22.04.3. See output below.

I assume iperf is called with --enhancedreports. However, this option seems to have been renamed, looking at the announcement for iperf 2.0.13 [1] and e.g. current man pages for iperf 2.1.8 on Debian "bookworm" [2] or iperf2 istself [3], in which it is named -e, --enhanced.

Is it better to grab flent from the repo? I noticed in Ubuntu 24.04, the flent package version 2.1.1 doesn't include the fix for the iperf --enhancedreports to --enhanced change.

Well, ATM the git version contains fixes that the release version doesn't, so yeah, if you need those fixes, use the version from the repository :)
