apt install iperf3
with SCTP which gets enabled at compile time without any specific flag, as long as you got the headers available,
sbopkg -i lksctp-tools sbopkg -i iperf3
same thing, about the SCTP headers – http://lksctp.sourceforge.net/ – https://github.com/sctp/lksctp-tools
eventually clean-up your shit
pkill iperf3 ps aux | grep iperf3 removepkg iperf3
then check latest release
wget https://github.com/esnet/iperf/archive/3.6.tar.gz tar xzf 3.6.tar.gz cd iperf-3.6/ ./configure grep -i sctp config.log make -j16 make -j16 install ldconfig
