SUSE Linux下安裝配置VSFTP

在SUSE Linux下安裝配置VSFTP

下面簡單介紹下在SuSE Linux下安裝配置VSFTP及使用方法。

一，準備條件

　　VSFTPD默認配置中需要“nobody”用戶。在系統中添加此用戶，如果用戶已經存在，useradd命令有相應提示。
　　[root@hpe45 root]# useradd nobody
　　useradd: user nobody exists

　　VSFTPD默認配置中需要“/usr/share/empty”目錄。在系統中此目錄，如果目錄已經存在，mkdir命令有相應提示。
　　[root@hpe45 root]# mkdir /usr/share/empty/
　　mkdir: cannot create directory '/usr/share/empty': File exists

　　VSFTPD提供匿名FTP服務時，需要“ftp”用戶和一個有效的匿名目錄。
　　[root@hpe45 root]# mkdir /var/ftp/
　　[root@hpe45 root]# useradd -d /var/ftp ftp
　　接下來的操作對於ftp用戶是否已經存在都是有用的。
　　[root@hpe45 root]# chown root.root /var/ftp
　　[root@hpe45 root]# chmod og-w /var/ftp[z1] 

 一般情況下，安裝好vsftp後，不用做任何配置，應該可以通過本地用戶名和密碼登錄ftp服務器，默認目錄是用戶根目錄。確保ftpusers和user_list文件中沒有要登錄的用戶名，要不然該用戶可能被排除在外。ftpusers和user_list在/etc或者/etc/vsftpd目錄中。

    注意的地方有：

    1、確保但不全有下面配置項 vsftpd.conf

二，安裝
yast -i vsftpd就行了

三，配置
配置要修改文件 /etc/vsftpd.conf
write_enable=YES
　anon_world_readable_only=YES|NO
　　控制是否只允許匿名用戶下載可閱讀文檔。YES，只允許匿名用戶下載可閱讀的文件。NO，允許匿名用戶瀏覽整個服務器的文件系統。默認值爲YES。

　　anon_upload_enable=YES|NO
　　控制是否允許匿名用戶上傳文件，YES允許，NO不允許，默認是不設值，即爲NO。除了這個參數外，匿名用戶要能上傳文件，還需要兩個條件：一，write_enable參數爲YES;二，在文件系統上，FTP匿名用戶對某個目錄有寫權限。

　　anon_mkdir_write_enable=YES|NO
　　控制是否允許匿名用戶創建新目錄，YES允許，NO不允許，默認是不設值，即爲NO。當然在文件系統上，FTP匿名用戶必需對新目錄的上層目錄擁有寫權限。

　　anon_other_write_enable=YES|NO
　　控制匿名用戶是否擁有除了上傳和新建目錄之外的其他權限，如刪除、更名等。YES擁有，NO不擁有，默認值爲NO。
重點：吧var/ftp下的某個文件夾chown給ftp就可以匿名寫入了

vsftpd &直接運行
chkconfig set vsft  pd on系統啓動時自動運行

 

 

 

 

本地及匿名用戶都可以登陸

我的配置文件:vsftpd.conf

# 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.

#

# If you do not change anything here you will have a minimum setup for an

# anonymus FTP server.

#

# 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.

 

# General Settings

#

# Uncomment this to enable any form of FTP write command.

#

write_enable=YES

#

# Activate directory messages - messages given to remote users when they

# go into a certain directory.

#

dirmessage_enable=YES

#

# 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

#

# You may fully customise the login banner string:

#

ftpd_banner="歡迎登陸FTP！"

#

# 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

#

# 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

#

# If  enabled,  all  user  and  group  information in

# directory listings will be displayed as "ftp".

#

#hide_ids=YES

 

# Local FTP user Settings

#

# Uncomment this to allow local users to log in.

#

local_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 to put local users in a chroot() jail in their home directory

# after login.

#

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/chroot_list

#

# The maximum data transfer rate permitted, in bytes per second, for

# local authenticated users. The default is 0 (unlimited).

#

#local_max_rate=7200

 

 

# Anonymus FTP user Settings

#

# Allow anonymous FTP?

#

anonymous_enable=YES

#

# Anonymous users will only be allowed to download files which are

# world readable.

#

anon_world_readable_only=YES

#

# 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

#

# Default umask for anonymus users is 077. You may wish to change this to 022,

# if your users expect that (022 is used by most other ftpd's)

#

#anon_umask=022

#

# Uncomment this if you want the anonymous FTP user to be able to create

# new directories.

#

anon_mkdir_write_enable=YES

#

# Uncomment this to enable anonymus FTP users to perform other write operations

# like deletion and renaming.

#

#anon_other_write_enable=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

#

# The maximum data transfer rate permitted, in bytes per second, for anonymous

# authenticated users. The default is 0 (unlimited).

#

#anon_max_rate=7200

 

 

# Log Settings

#

# Log to the syslog daemon instead of using an logfile.

#

syslog_enable=YES

#

# Uncomment this to log all FTP requests and responses.

#

#log_ftp_protocol=YES

#

# Activate logging of uploads/downloads.

#

xferlog_enable=YES

#

# You may override where the log file goes if you like. The default is shown

# below.

#

#vsftpd_log_file=/var/log/vsftpd.log

#

# If you want, you can have your log file in standard ftpd xferlog format.

# Note: This disables the normal logging unless you enable dual_log_enable below.

#

xferlog_std_format=YES

#

# You may override where the log file goes if you like. The default is shown

# below.

#

#xferlog_file=/var/log/xferlog

# Uncomment this to enable session status information in the system process listing.

#

#setproctitle_enable=YES

 

# Transfer Settings

#

# Make sure PORT transfer connections originate from port 20 (ftp-data).

#

#

# 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

#

# 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 turning on ascii_download_enable enables malicious remote parties

# to consume your I/O resources, by issuing the command "SIZE /big/file" in

# ASCII mode.

# These ASCII options are split into upload and download because you may wish

# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),

# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be

# on the client anyway..

#

#ascii_upload_enable=YES

#ascii_download_enable=YES

#

# Set to NO if you want to disallow the  PASV  method of obtaining a data

# connection.

#

#pasv_enable=NO

 

# PAM setting. Do NOT change this unless you know what you do!

#

pam_service_name=vsftpd

 

# Set listen=YES if you want vsftpd to run standalone

# Set to ssl_enable=YES if you want to enable SSL

ssl_enable=NO
