iperf 3.1.5 not showing server summary for UDP

Can anyone narrow down what the causes of "connect failed: Network is unreachable" might be? I'm using iperf 2.0.13 on Android. Command used is iperf2-arm --client 192.168.1.3 --time 10 --port 5001 --parallel 1 --interval 1 --udp --bandwidth 50M -f k

I'm having difficulty getting multicast to work with iperf 2.0.10 or 2.0.13. I'm using wifi between an Android phone and a PC with an AP attached. The client seems to be happy but the server doesn't seem to be receiving anything. Any suggestions? Both of the following show nothing received at server: Linux: iperf2-x86 -s -B 239.255.0.1 --time 12 --parallel 1 --interval 1 --udp -f k Android: iperf2-arm --client 239.255.0.1 --interval 1 --udp -f k --ttl 7 Linux: iperf --server --format k --port 5001...

OK, let me do some tests.

It might be possible to use -t. What does -t actually do? If I say -t 10 does it exit 10s after starting or 10s after the client connects? There may be 3-5 seconds between our server starting and our client connecting but default duration is 10s so the difference is important.

When will 2.0.14 be available?

The work around isn't ideal - particularly if I should use the SUM report when there is more than one stream. A patch would be good if not too difficult. I'm using Linux and Android but I've never got round to building my own - I'm just relying on binaries people have posted on the web.
