sshping

Use this utility to test the performance of interactive ssh sessions or scp file transfers. It uses ssh to log into a remote system, then runs two tests: the first test sends one character at a time, waiting for each character to be returned while it records the latency time for each. The second test sends a dummy file over scp to /dev/null on the remote system.

For the echo test, you may specify a character count limit (-c) or a test time limit (-t), and also the command (-e) used on the remote system that echoes characters back.

For the speed test, you may specify the number of megabytes to send (-s) and the target location for the copies (-z).

The default output format is RFC-2822 compliant with simple integers so parsing is easy. You may also display delimiters to make reading of large numbers easier, or you may use a "human readable" format that displays values using SI prefixes to keep the numberic value small.
