We make a server restart proftpd

1
systemctl restart proftpd.service

Add the FTP user permissions and give it close in the directory

1
useradd --shell /bin/false uzytkownikftp

1
mkdir /home/uzytkownikftp

1
chown uzytkownikftp:uzytkownikftp /home/uzytkownikftp/

We do change the password for the user uzytkownikftp

1
passwd uzytkownikftp

That's all, we can log into our ftp server 😉
