I wrote several messages about the basic setup of Armbian on OrangePi. All of them were using line commands. Along the self-learning path, someday I found that there is armbian-config command that starts up a menu utility, roughly corresponds to raspi-config utility. However, before this Armbian version (20.02.1, Armbian Stretch for OrangePi Lite 2), I have a tough time dealing with this utility. Until today, I can say armbian-config works now. Therefore, many things can now be done in a menu-driven approach. Because I never lay down any can-opener style startup notes, this is the guide: Download an Armbian software from Armbian website. You will get a 7z zipped file in your downloads directory. Unzip the file. I just use 7zip Unzip Here feature. Use an SD card writer program (like Win32DiskImager) to write the unzipped file into the SD card. Connect OrangePi debug port to TTL-USB device. Connect USB to the computer, and startup PuTTY, open the connected USB COM port, with sp...

This is a simple installation note for Linux FTP server vsftpd. I only want it to communicate with my PC Filezilla client to upload/download files. No fancy nor serious configuration wanted. 1. Install the software   sudo apt-get install vsftpd  2.  Edit configuration file sudo nano /etc/vsftpd.conf 3. Uncomment/change these lines and save the file local_umask = 022 write_enable = true  4. Start the service sudo systemctl start vsftpd  5. Make it a startup service sudo systemctl enable vsftpd 6. In case you changed some settings sudo systemctl restart vsftpd Use the default username and password. The home directory will be the user's directory. Kevin Lee 19 March 2020 Hong Kong.
