A network administrator is using iperf3 to troubleshoot network throughput between two Linux servers, ServerA (10.0.1.10) and ServerB (10.0.1.20). The administrator starts the iperf3 server process on ServerA. To measure the download speed from ServerA to ServerB, which command should be executed on ServerB?
The correct command is iperf3 -c 10.0.1.10 -R. By default, an iperf3 test sends data from the client to the server, which measures the upload speed of the client. The -R (or --reverse) flag reverses the direction of the test, causing the server (ServerA) to send data to the client (ServerB). This correctly measures the download speed on the client machine. The command iperf3 -c 10.0.1.10 would measure the upload speed from ServerB to ServerA. The command iperf3 -s -c 10.0.1.10 is invalid because the -s (server) and -c (client) flags are mutually exclusive. The --get-server-output flag is used to retrieve the server's final report at the client, but it does not alter the direction of the data transfer.
