FTP server
To install a FTP server on the Raspberry PI use this:
sudo apt update
sudo apt full upgrade
sudo apt install vsftpd
sudo nano /etc/vsftpd.conf
In this file add or uncomment these settings:
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
After that you can logon with an FTP program using your raspberry PI credentials.
