For my wedding anniversary this year, my wife bought me a Hootoo HT-TM02 (amongst other things). How nerdy is that? But it's a nice little machine which can have the default firmware replaced with OpenWrt. For about USD $16.00 it's a very cheap way to have an embedded Linux machine. Personally, I didn't even try the standard firmware and put OpenWrt on straight away. It was pretty easy, but you need a USB stick to give the device some extra storage during the initial upgrade process. The instructions are here and the process was very smooth.
As soon as I had the initial OpenWrt installation, I decided to switch to trunk OpenWrt, so I used the
sysupgrade command to install the 15.05 trunk image from here. So this left me with a device running trunk OpenWrt. I then held the reset button in (whilst the device was powered on) for 30 seconds to make sure that the configs were all at default settings.
Next, I decided to install relayd to bridge the LAN (ethernet) port with my existing Wi-Fi network. I followed the instructions here and that seemed to work fine. I felt that I had followed those instructions exactly; but the OpenWrt firewall was still getting in the way. So I just went ahead and disabled the firewall by using:
After doing that, I can switch off the Wi-Fi on my laptop, connect a network cable between the Hootoo and the laptop and I'm on my network. The Hootoo is acting as a bridge between my own Wi-Fi and its own ethernet socket, very nice!
The next thing I need to do is cross-compile some code and get it running on the Hootoo.
