I just created an azure vm with Ubuntu and noticed that I am able to FTP into it without having installed an FTP app like vsFTP. It just works, as far as FTP viewing goes.
I can read files from my Django project in the var/www directory, but I am unable to upload. Can these permissions be managed without installing an FTP application? Or is the FTP connection normally allowed by Linux just because the port is open, whereas an FTP program is needed for more advanced management?
