filemanager-http

If you are not concerned about security you could run a file manager using a web browser, and configure nanopi-r2s as a gateway.

just run :

ubuntu@nanopi-r2s:~$ sudo /usr/local/bin/filemanager-httpd

Configuring WAN (eth0)

You can configure your WAN interface as a DHCP, fixed IP or according to your service provider. Edit the file /etc/network/interfaces and change the eth0 configuration as desired, in my case i have DHCP (default):

Client connection (DHCP)

A Linux desktop connected to the LAN interface of our mini router to surf the internet.

v0.3 - Mini Router NanoPi R2S with eth-monitor

Kernel updated to 5.4.28 with eth-monitor to display the eth status for the WAN and LAN interface. When the WAN is up, the WAN led will be ON, when down, WAN led will be OFF.

https://github.com/avafinger/nanopi-r2s-ubuntu-server-minimal-image/releases/tag/v0.3

v0.4 - Mini Router NanoPi R2S with eth-monitor

Kernel updated to 5.6.2 with eth-monitor to display the eth status for the WAN and LAN interface. If WAN is up, the WAN led is ON, if down, WAN led is OFF. Same for the LAN interface.

eth-monitor runs as service. You can stop, start or see the status of the service.

  sudo systemctl status eth-monitor.service
  sudo systemctl stop eth-monitor.service
  sudo systemctl start eth-monitor.service

v0.5 - Ubuntu 20.04 LTS Server with Kernel 5.6.5 (Experimental)

Our mini router is kind of slow on the iptable NAT routing/fowarding and i can't find a way to optimize it or don't know how to do it. For this reason we will try the Ubuntu Beta version and see what we can get, all from scratch. In my experiments, the routing and forwarding is 8x slower than using the Gigabit port directly, maybe the NAT rules are overkill somewhere.

Add Initial support for rtl8822bu with Ubuntu Focal, the smallest Image size i could get, just for evaluation on RK3328 boards.

v0.95 - Kernel 5.8.0

Mainline Kernel 5.8.0 built on-board with gcc 9.3 to ensure it is really stable. Build was done with the yellow case. Thermal throttling has been adjusted to hit at 80ºC , so if you plan to use intensive cpu applications the board can reach 80ºC and scale down to 1.3 GHz, can also reach 85ºC really easy but will scale down to 1.2 GHz or even 1 GHz. During the kernel build with 4 cores 100% the board was running with 1.3 GHz most of the time.

Controlling FAN speed control with pwm0

We are going to build a service to control the fan speed according to the cpu temperature. Mainline kernel has exposed the pwm0 where we can output voltage from 2.6v to 5.0v and control the fan speed.

Enabling the pwm0

sudo su
echo -n 0 > /sys/class/pwm/pwmchip0/export

pwm0 is now exposed as /sys/class/pwm/pwmchip0/pwm0

Source code for the tiny systemd service is available here: https://github.com/avafinger/fan-speed-control

At startup, the pwm0 pin drives 5v and make Fan full speed. The service will check the CPU Temp and try to drive the speed of the Fan, so the noise is minimum, or should be.

The service has been tested with good results with the snowfan that comes with NanoPi M3.

I would like to thank the Folks at FriendlyElec for the sample board and the work on the kernel side. The current Kernel version 5.7.0 release is the stable Linux Kernel with the FriendlyElec's work on USB3. The benchmark sample was taken with nanoPi R2S without case, your results may vary.
