I have the following configuration: computer1 - iperf client computer2 - iperf server computer3 - ssh intermediary computer
I am able to use "iperf -c computer2 -u -b 5M" from computer1 just fine.But, if I use ssh to locally port forward port 5001 from computer1 to computer3, and remotely port forward port 5001 from computer3 to computer2, and then try:
"iperf -c localhost -u -b 5M" on computer1, I get the following: write2 failed: Connection refused read failed: Connection refused [ 3] WARNING: did not receive ack of last datagram after 1 tries. ------------------------------------------------------------ Client connecting to localhost, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 105 KByte (default) ------------------------------------------------------------ [ 3] local 127.0.0.1 port 2048 connected with 127.0.0.1 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 0.0 sec 1.44 KBytes 2.66 Mbits/sec [ 3] Sent 1 datagramsIf I use TCP, everything works fine, but for some reason UDP doesn't work via the port forwarding. Any ideas on why TCP would work but not UDP over port 5001?
