The Odroid devices make great iPerf servers for portable use as they can be powered by 5V micro USB and have a Gigabit Ethernet adapter on its own bus so they don’t have the limitations the Raspberry Pi’s do. OK, let’s get started.
We are going to assume that you already have Ubuntu 16.04 up and running but if not, you can download official images here http://odroid.com/dokuwiki/doku.php?id=en:c1_release_linux_ubuntu. Extract the downloaded image and burn it to a SD Card using Win32 Disk Imager. I only used a 2GB card and it works fine. First boot might take a minute or two. After it’s booted, scan your network (Fing) to find your device IP. It should show up as a device by JF Light Industries with the MAC vendor as Wibrain.
