Total Noob Question: This is my first time setting up a VPS and ftp user, following is what I did. 1. Launch a Linode.com server using the a stackscript. 2. Ran Centmin mod to install virtual host on that server (Centmin Mod Nginx Vhost) It asked to give a ftp username and password and I gave that. 3. Restarted the ftp service using Quote: pure-pw mkdb && service pure-ftpd restart But I want unable to access it via ftp so I tried creating another user via the following command in SSH Quote: pure-pw useradd ftpuser -u nginx -g nginx -d /home/nginx/domains/ but It gives me an error "You must give nonroot uid and gid". I am stuck, how can create a master user to access ftp. What should I do?
