Anonymous FTP allows anyone access.
Anonymous servers are convenient for users, but can pose a security threat if not cared
for. Fortunately, openSUSE Linux uses logical permission schemes and a default configuration
that makes it difficult for you to make mistakes.
openSUSE Linux users can build both types of FTP servers, but this section will focus on
securing an anonymous server with the Very Secure FTP server package, vsftpd.
Configuring xinetd for Secure File Transfer
Starting an FTP service in openSUSE is relatively simple, thanks to YaST. Go to the
Network Services section and click Network Services (xinetd). xinetd allows you to apply
individual access policies for different network connection requests, such as FTP.
To turn VSFTP on xinetd, first click the Enable button at the top of the Network Services
Configuration screen. The various services that can be controlled by xinetd become active
and are no longer grayed out. Check the Status column??”you can start or configure any of
the services marked with three dashes (??”-). The dashes indicate that a service is inactive;
any services that are running now are labeled ON and are also configurable.
