vsftpd可以对每个用户特别限制.
只要给那个用户建立一个设置文件,然后在文件里设置

在vsftpd.conf里加
user_config_dir=/etc/vsftpd/vsftpd_user_conf,这是文件夹.当然你可以自己选把用户文件放在哪
在此文件夹里新建一个文件,跟用户名相同.VSFTPD会比对用户名和用户设置文件.

在文件里加
local_root=PATH to directory就可以更改用户的home directory
local_max_rate=XXXX就可以限制此用户的带宽.
cmds_allowed=XXXXX, 此用户可以使用的指令

# ABOR – abort a file transfer
# CWD – change working directory

在线使用的脚本

local_root=/home/dbbackup
cmds_allowed=MKD,LIST,PASV,ABOR,REST,NLST,RMD,RNFR,FNTO,SIZE,PORT,STOR,QUIT
local_max_rate=80000000

前提配置文件中要开启：

tcp_wrappers=YES

限制ip访问，只使用hosts.allow文件即可，不用动hosts.deny文件

vsftpd:222.90.72.87 61.150.91.10:allow
vsftpd:all:deny
