为了验证局域网网络安装Linux，近两天做了一个实验，目的就是为了写一篇比较完整的文章。

1. 本文操作环境是Redhat 9.0,VSFTPD的版本是Redhat 9.0所带的vsftpd-1.1.3-8.i386.rpm，在安装盘的第三张中

2. VSFTPD实现的最基本的目的：用系统中存在的真实用户能登入FTP，能用匿名访问。

3. 服务器的IP和和DNS设定

第一块网卡

IP：192.168.0.1

子掩码：255.255.255.0

网关不设置：

第二块网卡：

IP：192.168.0.2

子掩码：255.255.255.0

网关不设置

因为我的操作环境是一个小型的局域网，所以其它的机器的IP都是在192.168.0这个网段上。ADSL是接在服务器的第一个网卡上。服务器的第二个网卡是接集线器，其它的客户机都是接在集线器上。为了能让ADSL访问inte.net，因为自己手动设置了IP，所以DNS也要自己来设置，DNS如下：

202.96.134.133

202.96.168.68

设置工具是：

[root@linuxsir001 root]# redhat-config-network

一、用VSFTP来架设FTP服务器，VSFTP服务器是目前最好的FTP服务器软件，优点是体积小，可定制强，效率高

1. 查看是否安装了vsftpd软件

[root@linuxsir001 root]# rpm -qa | grep vsftpd

如果没有任何显示，说明没有把vsftpd安装上，如果出现的是下面的这样的提示，就证明已经安装上了。

[root@linuxsir001 root]# rpm -qa | grep vsftpd

vsftpd-1.1.3-8

我以Redhat 9.0，以其自带的vsftpd包vsftpd-1.1.3-8版本来为本帖约定。

[root@linuxsir001 root]# rpm -ivh vsftpd*.rpm

2. 打开VSFTP服务器。

[root@linuxsir001 root]# ntsysv

把vsftpd服务器打开，也就是在运行 ntsysv命令后，把vsftpd服务选中。

[*] vsftpd

3. 运行/etc/init.d/vsftpd start

[root@linuxsir001 root]# /etc/init.d/vsftpd start

为 vsftpd 启动 vsftpd：[ 确定 ]

[root@linuxsir001 root]#

4. 配制VSFTP，FVSFTP的运行有两种模式，一种是stardard "initd模式，另外一种是xinetd模式，上面我们所说的就是stardard initd运行模式。两种模式运行机制不是相同的，stardard initd模式，适合专业FTP，且FTP总是一直有人访问，占用资源也是比较大，如果您的FTP总是有人访问和登入。就要用这种模式。如果您的FTP访问人数比较小，建议您用xinetd模式。xinetd模式，是当用户请求时，vsftpd才会启动。

不同的环境，当然得用不同的启动模式。

如果想了解更多的，请在本帖后面跟帖，我会慢慢补充xinetd模式，以及虚拟用户如何设置方面的问题。

1]我们主要把vsftp的配制文件改一下就行了。配制文件在/etc/vsftpd/vsftpd.conf，用您喜欢的编辑器打开。请参考下面的配制文件。

# Example config file /etc/vsftpd.conf

#

# The default compiled in settings are very paranoid. This sample file

# loosens things up a bit, to make the ftp daemon more usable.

#

# Allow anonymous FTP?

anonymous_enable=YES

#

# 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 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

#

# You may fully customise the login banner string:

#ftpd_banner=Welcome to blah 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 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

pam_service_name=vsftpd

userlist_enable=YES

#enable for standalone mode

listen=YES

tcp_wrappers=YES
