配置VSFTP服务器

配置VSFTP服务器，主要参考网上的资料，结合自己实际写下一些体会。
直接用yast命令安装，安装好的文件结构如下：
/etc/init.d/vsftpd  启动脚本
/etc/xinetd.d/vsftpd
/etc/pam.d/vsftpd   pam认证文件
/usr/share/doc/packages/vsftpd   
/usr/sbin/vsftpd   VSFTP主程序
/var/ftp   匿名用户主目录
/var/ftp/pub   匿名用户的下载目录
/etc/vsftpd.conf  配置文件
# Example config file /etc/vsftpd.conf
#

下面的配置允许匿名用户上传东西，但是不允许下载。
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
