vsftpd 設定 |

vsftpd 設定

通過vsftp限定用戶訪問目錄

1. 安裝vsftpd

2. Vi /etc/vsftpd/vsftpd.conf

修改如下:

匿名用戶

anonymous_enable=NO

anon_mkdir_write_enable=YES

anon_upload_enable=YES

本地用戶能否登陸

local_enable=YES

是否可寫

write_enable=YES

VSFTPD獨立運行 (用vsftpd /etc/vsftpd.conf &)以及下載速度的限制

listen=YES

max_clients=600

max_per_ip=5

tcp_wrappers=YES

connect_from_port_20=YES

anon_max_rate=51200 (56k)

local_max_rate=512000 (560k)

如何更改路徑

anon_root=/var/ftp/pub

local_root=/var/ftp

如何隨意增加一個用戶目錄

通過useradd -d /path/dir -M name 以及chmod ? /path/dir 可以達到

如何對磁碟限額

用quota對/etc/fstab進行限制,然後對特定用戶進行限制

如何把用戶限制在家目錄中呢?
先建立vsftpd組和用戶brian
groupadd vsftpd
Useradd -d /brian -g vsftpd brian
  我們要自己建一個文件,在/etc目錄中
  #touch /etc/vsftpd.chroot_list

  以brian這個用戶為例

  在vsftpd.chroot_list這個文件中,把brian添上去就行。

  然後改/etc/vsftpd/vsftpd.conf文件,找如下的兩行

  把前面的#號去掉,也就是這樣的

  chroot_list_enable=YES

  chroot_list_file=/etc/vsftpd.chroot_list

  如果沒有這樣的兩行,就可以自己添加上去也是一樣的。

  設置好後,重新vsFTPD伺服器。

打開vsFTP伺服器的日誌功能:

  把下面xferlog_file前面的#號對掉,也就是把vsftp的log功能打開,這樣我們就能在/var/log目錄下查看vsftpd.log。這是vsFTP的日誌功能,這對於我們來說是極為重要的。

  #xferlog_file=/var/log/vsftpd.log

  補充三:如何讓綁定IP到vsFTP?也就是說,如何讓用戶只能通過某個IP來訪問FTP。其實這個功能很有意思。如果綁定的是內網的IP,外部是沒有辦法訪問的。如果綁定的是對外服務的IP,內網也只能通過對外服務的IP來訪問FTP

  在/etc/vsftpd/vsftpd.conf中加一行,以我的區域網為例,請看第一帖中的操作環境,這樣外網就不能訪問我的FTP了,內網也可能通過192.168.0.2來訪問FTP

listen_address=192.168.0.2

  加完後,要重啟vsFTP伺服器

3. 限制用戶只能用ftp上傳、下載文件,而不能登陸

Vi /etc/passwd

brian:x:515:515::/brian:/sbin/nologin

現在試試看,只能用brian做上傳\下載文件,而不能登陸伺服器了.
