Using the YaST
module, you can configure your machine to function as an FTP (File Transfer Protocol) server. Anonymous and/or authenticated users can connect to your machine and download files using the FTP protocol. Depending on the configuration, they can also upload files to the FTP server. YaST uses vsftpd (Very Secure FTP Daemon).
If the YaST FTP Server module is not available in your system, install the
yast2-ftp-server
package.
To configure the FTP server using YaST, follow these steps:
Open the YaST control center and choose yast2 ftp-server
command as root
