To install execute the following command: `sudo apt install vsftpd`

Make backup of the **/etc/vsftpd.conf** by executing: `sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak`.
Clear all from the **/etc/vsftpd.conf** and paste the following lines:

```
listen=YES

anon_root=/srv/ftp/public

anonymous_enable=YES
no_anon_password=YES
write_enable=YES
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
anon_world_readable_only=YES
dirmessage_enable=YES
hide_ids=YES

ftp_username=ftp
```

Create a public anonymous folder in the directory **/srv/ftp** and set permissions by executing:
```bash
sudo mkdir /srv/ftp/public
sudo chmod 775 /srv/ftp/public
sudo chown nobody:nogroup /srv/ftp/public
```
Also create folder to upload files by executing:
```bash
sudo mkdir /srv/ftp/public/upload
sudo chmod 755 /srv/ftp/public/upload
sudo chown ftp:root /srv/ftp/public
```

After that, you can download files from *root* at FTP and upload files to directory *upload*.
