network test script needs better output

[Jeff Lane ]

The network test script needs to provide better output to checkbox... the problem seems to be that the output from the FTP session is dumped to stdout, while the debug logging all goes to stderr.

Since checkbox is an either-or when grabbing output, this means that on a successful test, we get this:
*cmd* 'USER ubuntu'
*put* 'USER ubuntu\r\n'
*get* '331 Please specify the password.\n'
*resp* '331 Please specify the password.'
*cmd* 'PASS ******'
*put* 'PASS ******\r\n'
*get* '230 Login successful.\n'
*resp* '230 Login successful.'
*cmd* 'CWD .'
*put* 'CWD .\r\n'
*get* '250 Directory successfully changed.\n'
*resp* '250 Directory successfully changed.'
*cmd* 'TYPE I'
*put* 'TYPE I\r\n'
*get* '200 Switching to Binary mode.\n'
*resp* '200 Switching to Binary mode.'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (172,16,5,50,124,0).\n'
*resp* '227 Entering Passive Mode (172,16,5,50,124,0).'
*cmd* 'STOR ftp_performance_test'
*put* 'STOR ftp_performance_test\r\n'
*get* '150 Ok to send data.\n'
*resp* '150 Ok to send data.'
*get* '226 Transfer complete.\n'
*resp* '226 Transfer complete.'

which doesn't inform us about the throughput speeds observed or any other data. All that logging data is only displayed if the test fails, however, it would be important to know what the throughput is even on successful tests.

Even since moving to iperf, there are some issues. The output on Success is ok, but the output on failure is lacking:

Now: Console output for success:
