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.
#
# 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 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 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

完成之后，设一下使用者禁止溜出家目录
vi /etc/vsftpd.chroot_list
xxx
xxx
:wq
接下来防火墙部份
/sbin/iptables -A INPUT -p TCP -i eth0 --dport 21 -j ACCEPT
或是可以直接把防火墙设定值清空也是可以通，只是多了危险就是
最后restart一下就可以用啦

FTP服务器软件有没有被安装？的输出。如果没有这个软件包，该命令会输出：package package_name is not installed.
可以通过RPM的命令进行检查。运行如下命令可以确认软件包是否已经被安装.
rpm -q vsftpd
如果该软件包已经被安装，该命令会返回格式类似package_name-
FTP服务有没有在运行，有没有监听客户端的请求?
如果该软件包已经被安装，就可以把FTP服务打开，这个操作可以通过命令chkconfig实现，然后通过servive命令把FTP服务立即启动.
# chkconfig --list | grep vsftpd
vsftpd: off
# chkconfig vsftpd on
# chkconfig --list | grep vsftpd
vsftpd: on
# service xinetd reload
Reloading configuration: [ OK ]
命令chkconfig可以使FTP 服务器在下次系统引导的时候自动启动，注意FTP不是一个单独的服务，他是存在于xinetd(超级服务器)，如果需要马上启动服务，可以使用 service xinetd reload命令启动，这个命令会重新读取和使用xinetd的配置文件，可以通过检查FTP的监听端口来查看服务，默认情况下监听端口是21，命令是 netstat -a | grep ftp.。输出如例子所示:
# netstat -a | grep ftp
tcp 0 0 *:ftp *:* LISTEN
这个用户是否有权限FTP到服务器上?
如果还不能正确的登录到FTP服务器,清检查你的用户是否有权限访问FTP服务器，默认情况下，基于安全的考虑，root用户不能访问FTP到Ubuntu9.04server机器。其他的系统用户都可以访问FTP服务。可以通过检查文件/etc/ftpaccess确认。
# Don't allow system accounts to log in over ftp
deny-uid %-99 %65534-
deny-gid %-99 %65534-
allow-uid ftp
allow-gid ftp
因为所有的用户帐号的UID应该大于等于500， 默认的ftpaccess文件是允许普通系统用户访问FTP的。
现在就可以成功的通过FTP连接到Ubuntu9.04server上。
# ftp flanders.example.com
Connected to flanders.example.com.

FTP服务有没有在运行，有没有监听客户端的请求?
这个用户是否有权限FTP到服务器上?
