我在 ec2 实例上配置 vsftpd 时遇到了一个非常奇怪的问题：我已将 ftp 服务器配置为使用 TLS 上的 ftp，并且它在 filezilla 上运行良好，但是我无法使用任何文本编辑器 ftp 模块进行连接（我尝试使用 notepad++ 和 webstorm）。我认为问题可能出在 SSL 上，所以我首先将其更改为简单的不安全 FTP，然后尝试使其工作。现在 FTP 客户端又可以正常工作了（filezilla、total commander），但成功连接后，上述文本编辑器给我以下错误：
Failure retrieving contents of directory /
我尝试了所有方法，但目前还不知道问题出在哪里。以下是我的 vsftp 配置：
listen=NO
listen_ipv6=YES
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
chroot_list_enable=NO
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=ftp
ssl_enable=NO
pasv_enable=YES
pasv_min_port=1024
pasv_max_port=1048
port_enable=YES
pasv_address=[EC2_PUBLIC_DOMAIN]
pasv_addr_resolve=YES
有人知道问题出在哪里吗？欢迎大家提供帮助。谢谢。

答案1
2017 年 1 月 14 日星期六 20:01:38 [pid 8103] [dev_back] FTP 响应：客户端“::ffff:178.48.165.229”，“227 进入被动模式（0,0,0,0“,4,2）”。
当设置公共时，这看起来像是 vsftpd FTP 服务器的一个错误，pasv_address并且服务器有一个（本地）IPv6 地址（EC2 的情况是这样的）。
我在 Server Fault 问题上发布了更多关于该 bug 的信息即使 pasv_address 正确，Vsftpd 也会使用 0,0,0,0 地址进行被动回复。
FileZilla 可以忽略无效的 IP 地址：
2017-01-14 21:27:42 4856 1 响应：227 进入被动模式 (0,0,0,0,4,12)。2017-01-14
21:27:42 4856 1 状态：服务器发送了带有不可路由地址的被动回复。改用服务器地址。
但 Notepad++ 不能。
