vsftp實現只能上傳不能下載、刪除權限配置

vsftpd能夠對每一個用戶特別限制.
只要給那個用戶創建一個設置文件,而後在文件裏設置

在vsftpd.conf里加
user_config_dir=/etc/vsftpd/vsftpd_user_conf,這是文件夾.固然你能夠本身選把用戶文件放在哪
在此文件夾裏新建一個文件,跟用戶名相同.VSFTPD會比對用戶名和用戶設置文件.

在文件里加
local_root=PATH to directory就能夠更改用戶的home directory
local_max_rate=XXXX就能夠限制此用戶的帶寬.
cmds_allowed=XXXXX, 此用戶能夠使用的指令

在線使用的腳本

local_root=/home/dbbackup
cmds_allowed=ABOR,CWD,LIST,MDTM,NLST,PASS,PASV,PORT,PWD,QUIT,RETR,SITE,SIZE,STOR,TYPE,USER,ACCT*,APPE,REIN*,STAT,SYST,REST,CDUP

local_max_rate=80000000

-----------------------------------------

前提配置文件中要開啓：

tcp_wrappers=YES


限制ip訪問，只使用hosts.allow文件便可，不用動hosts.deny文件

vsftpd:222.90.72.87 61.150.91.10:allow
vsftpd:all:deny
