我刚刚安装了 vsftpd，配置如下：
listen=NO
listen_ipv6=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
user_sub_token=$USER
local_root=/home/$USER/ftp
userlist_enable=YES
userlist_file=/etc/vsftpd.user_list
userlist_deny=NO
allow_writeable_chroot=YES
port_enable=YES
pasv_enable=Yes
pasv_address=XX.XX.XX.XX (public ip of router)
pasv_min_port=1100
pasv_max_port=1100
当我尝试在本地建立连接时，它工作正常。但是我无法在本地网络之外进入它。我将路由器 1100 上的端口重定向到本地端口 21。
当我尝试连接时，日志显示正在建立连接，但客户端无法列出目录 /home/$USER/ftp。我尝试使用两个客户端 total commander 和 winscp（结果相同）。
总司令官返回：
