Here are three steps that are necessary for the FTP daemon to allow connections:
- A non-root user must be created.
- The vsftp daemon must be started, you can do this with “/etc/init.d/vsftpd start”.
- The firewall must allow port 21. You can add the firewall run in Webmin or by editing /etc/sysconfig/iptables, then restarting the firewall with “/etc/init.d/iptables restart”
