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
