ubuntu 安裝 vsftp 教學與 設定 配置

圖一、到「系統→管理→Synaptic套件管理程式」



圖二、按下搜尋



圖三、輸入「vsftp」,並按下搜尋。



圖四、找到vsftp後在核取方塊上點一下,選擇標記為安裝。

接下來安裝後就要看文字了。

安裝完後。來設定vsftp.conf檔案嘍。

本教學是的ftp權限使用方式是。

匿名:
無法使用

實體用戶:
建立一個mkblog作為例子
mkblog使用者可以上傳下載建立資料夾,只限在自己的家目錄,無法瀏覽其他資料夾。
相對的也可以建立更多使用者,方式都一樣


你可以使用root開啟檔案總管,然後開啟/etc/vsftpd.conf,並編輯他
或者是直接在終端機內輸入。

sudo gedit /etc/vsftpd.conf

接下來以下為我的參數設定:
#==================================================

# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
#
# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=YES
#
# Run standalone with IPv6?
# Like the listen parameter, except vsftpd will listen on an IPv6 socket
# instead of an IPv4 one. This parameter and the listen parameter are mutually
# exclusive.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
#ftpd_banner=Welcome to OIpingo FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails
#
# You may restrict local users to their home directories. See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
#chroot_local_user=YES
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
chroot_list_enable=YES
# (default follows)
chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
#ls_recurse_enable=YES
#
#
# Debian customization
#
# Some of vsftpd's settings don't fit the Debian filesystem layout by
# default. These settings are more Debian-friendly.
#
# This option should be the name of a directory which is empty. Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
secure_chroot_dir=/var/run/vsftpd
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
# This option specifies the location of the RSA key to use for SSL
# encrypted connections.
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key


#可以接受的最大clinet可連線的數目
max_clients=20
#每個ip的最大連線數目
max_per_ip=15
#啟用被動式連線
pasv_enable=YES

#設定連線的port,可以自訂
listen_port=21

#===紅色是有開啟的項目=================


接下來在終端機輸入

sudo gedit /etc/vsftpd.chroot_list

並輸入你要限制的使用者,這個例子是mkblog。



填入後存檔在/etc/下,檔名存成「vsftpd.chroot_list」。
如果你的ftp使用者不只一個的話,就直接打在裡面就可以了。
﹍﹍﹍﹍﹍﹍﹍﹍
ex:
mkblog
mkblognewuser
mkhomeboy
mkweb
.
.
.等等
﹍﹍﹍﹍﹍﹍﹍﹍



然後建立該使用者
新增一位使用者名為mkblog,密碼要六個以上唷!
輸入後按下確定。就新增一位使用者了。


再來是歡迎訊息。
使用筆記本編輯一些文字後,將檔案存成「.message」別懷疑沒錯,
就是這個檔名,然後放在每一位使用者的家目錄下。
以這個例子mkblog使用者,我就把「.message」存在 /home/mkblog底下就可以了。

你也可以根據不同的使用者,而編輯不同的歡迎訊息。
不過切記。檔案名稱一定要「.message」,因為是放在不同的資料夾,所以不用擔心。



最後在到終端機輸入

sudo /etc/init.d/vsftpd restart

重新啟動vsftpd就完成啦。
並且以後重開機後,用戶就可以直接連線,不部用登入桌面來啟動vsftpd唷!
