I am compiling a list of bandwidth testers and hoping to give a short description/review of each.

1. dstat
2. iperf
3. You can use ftp (not sftp) and pipe the output from a local command to the remote side, and save the remote to /dev/null to avoid filling the remote disk (and needing to clean-up afterwards). You can, for example, use dd to send 1GB of data from hard disk partition such as sda1:

   ftp <server>
   put "|dd if=/dev/sda1 bs=1M count=1024" /dev/null

4. To test bandwidth from a Linux box to the outside you can use this Python script that uses speedtest.net:

   wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
