Hello @list! I am would like to use IPERF v 2.0.2 from source to performance my network connection between two nodes, wich are link each other with a CAT 6 cross Giga cable... I run the A-node this command: iperf -s And I run some test from B-node: 1. iperf -c 10.0.0.1 -t 30 2>&1 The output: [ 3] local 10.0.0.2 port 60779 connected with 10.0.0.1 port 5001 [ 3] 0.0-30.0 sec 3.29 GBytes 941 Mbits/sec It was success! 2., iperf -c 10.0.0.1 -d -t 30 2>&1 Out: [ 4] local 10.0.0.2 port 60780 connected with 10.0.0.1 port 5001 [ 5] local 10.0.0.2 port 5001 connected with 10.0.0.1 port 47810 [ 4] 0.0-30.0 sec 2.82 GBytes 806 Mbits/sec [ 5] 0.0-30.0 sec 2.82 GBytes 806 Mbits/sec SUCCESS! 3., iperf -c 10.0.0.1 -P10 -t 30 2>&1 Out: [ 12] local 10.0.0.2 port 60790 connected with 10.0.0.1 port 5001 [ 4] local 10.0.0.2 port 60782 connected with 10.0.0.1 port 5001 [ 5] local 10.0.0.2 port 60783 connected with 10.0.0.1 port 5001 [ 8] local 10.0.0.2 port 60786 connected with 10.0.0.1 port 5001 [ 7] local 10.0.0.2 port 60785 connected with 10.0.0.1 port 5001 [ 6] local 10.0.0.2 port 60784 connected with 10.0.0.1 port 5001 [ 9] local 10.0.0.2 port 60787 connected with 10.0.0.1 port 5001 [ 10] local 10.0.0.2 port 60788 connected with 10.0.0.1 port 5001 [ 3] local 10.0.0.2 port 60781 connected with 10.0.0.1 port 5001 [ 11] local 10.0.0.2 port 60789 connected with 10.0.0.1 port 5001 [ 12] 0.0-30.0 sec 335 MBytes 93.8 Mbits/sec [ 4] 0.0-30.0 sec 334 MBytes 93.3 Mbits/sec [ 6] 0.0-30.0 sec 335 MBytes 93.6 Mbits/sec [ 9] 0.0-30.0 sec 351 MBytes 98.2 Mbits/sec [ 10] 0.0-30.0 sec 333 MBytes 93.2 Mbits/sec [ 3] 0.0-30.0 sec 335 MBytes 93.7 Mbits/sec [ 11] 0.0-30.0 sec 337 MBytes 94.1 Mbits/sec [ 5] 0.0-30.0 sec 336 MBytes 94.1 Mbits/sec [ 8] 0.0-30.0 sec 334 MBytes 93.4 Mbits/sec [ 7] 0.0-30.0 sec 335 MBytes 93.8 Mbits/sec [SUM] 0.0-30.0 sec 3.29 GBytes 941 Mbits/sec SUCCESS!
