#syslog_enable=YES

#dirlist_enable=YES

chroot_local_user=YES

local_root=/usr/local/apache/htdocs/   #所有本地用户的根都是该目录

pasv_min_port=9981

pasv_max_port=9986

关于错误

ftp> ls

215 UNIX Type: L8

500 OOPS: vsf_sysutil_recv_peek

userlist_file=/etc/vsftpd.usr_list

tcp_wrappers=YES

port_enable=NO

pasv_enable=YES

cannot change directory:/home/***

ftp服务器连接失败,错误提示:

500 OOPS: cannot change directory:/home/*******
500 OOPS: child died

解决方法:

man ftpd_selinux

在终端输入命令：

setsebool ftpd_disable_trans 1 

/usr/sbin/setsebool -P ftp_home_dir 1

注意一定要重启

service vsftpd restart

就ＯＫ了！

passive模式，如果想在windows下使用命令行自动化上传或下载ftp的内容，可以使用ncftp，

下载安装后，改工具提供多个命令，如：

•  - FTP browser program
•  - command-line utility program
•  - command-line utility program
•  - command-line utility program
•  - background FTP program for individual users
•  - background batch FTP service for systems

关于使用xp自带的ftp工具不能连接时：

ftp> ls
200 PORT command successful. Consider using PASV.
425 Failed to establish connection.

Here is what I have tried...
1. I have tried going into PASV mode by typing 'quote PASV' with the same
results.
2. Other computers on my same network can access the server fine (XP Pro,
Server 2000, and Server 2003).
3. Installed Core FTP and it connects to the server fine
4. IE connects to the server fine
5. netstat shows an active connection to the server on port 21 ( TCP
Kiwi:2143 xxx.xxx.xxx:ftp ESTABLISHED)

This is an Active-mode / Passive mode problem. FTP.exe that ships with
Windows only supports active mode. Entering the 'quote PASV' command
puts the server in passive mode, but the client is still in active
mode. You need to find an FTP client that supports passive mode.

f you've ever setup vsftpd and noticed that when you login it defaults the user to their home directory

eg: user anyweb will ftp in to

/home/anyweb/

then how can you let that user access another folder outside of their home ?

using bind !

here's a quick example

[root@www anyweb]# mkdir ftp2
[root@www anyweb]# mount --bind /ftp2  /home/anyweb/ftp2
[root@www anyweb]# mkdir ftp3
[root@www anyweb]# mount --bind /ftp3  /home/anyweb/ftp3
