vsftpd启动问题简记

centos7 能以ipv6方式启动，启动只需修改配置如下

如需同时启动到ipv4跟ipv6，需拷贝配置文件，一份配置中只监听ipv4，一份配置中只监听ipv6

centos6中无法启动到ipv6,错误如下，20，21端口也没被其它程序占用：

以ipv4的方式启动vsftpd，在获取文件信息，下载文件，只能以主动模式运行，而ipv6可以以被动模式运行

python中ftplib进行ftp的代码（下载文件，获取文件信息），设为主动模式i，在window能正常运行，但是放到Linux下就跑不起来，会报“500 Illegal PORT command”，如果使用ftp工具，目标服务器是能进行文件上传下载的，具体需要看下ftplib的说明文档

写了一个工具类，有点乱
