1．安装VSFTPD-1.2.1
# gzip ?d vsftpd-1.2.1.tar.gz
# tar xvf vsftpd-1.2.1.tar
# cd vsftpd-1.2.1
# make
# make install -f Makefile.sun
# mv vsftpd.conf /etc/
# mkdir /usr/share/empty
2． 建立vsftp用户和目录
# groupadd ftp
# mkdir /export/home/test //建下载目录
# mkdir /export/home/test/upload //建上传目录
# chown test:ftp /export/home/test/upload
# useradd -d /export/home/test -g ftp -s /bin/false test //实际使用的USER
# useradd -d /dev/null -g ftp -s /bin/false upload //要用来影射的USER
# useradd -d /dev/null -g ftp -s /bin/false download //要用来影射的USER
# passwd download
# passwd upload
3． 分别对每个用户进行控制
目录限制:
# vi /etc/vsftpd.chroot_list
test
限制download只能下载，允许upload下载和上传:
# mkdir /etc/vsftpd
# vi /etc/vsftpd/download
anon_world_readable_only=no
anon_max_rate=51200
# vi /etc/vsftpd/upload
anon_world_readable_only=no
write_enable=YES
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_max_rate=102400
# vi /etc/vsftpd.user_list
download
upload
4．配置vsftpd.conf
========================== 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.
#
# 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=NO
#
# 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=NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=NO
#
# 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=nobody
#
# 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 my PROFTPD 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
user_config_dir=/etc/vsftpd
#
# 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=NO
hide_ids=YES
userlist_enable=yes
userlist_deny=no
userlist_file=/etc/vsftpd.user_list
guest_enable=YES
guest_username=test
max_clients=50
max_per_ip=2
pasv_min_port=55000
pasv_max_port=55100
listen=YES
listen_address=192.168.0.1
========================== vsftpd.conf============================
5． 建立VSFTPD的启动脚本
# vi /etc/rc3.d/S83vsftpd
================================= S83vsftpd ============================
#!/sbin/sh
#
# Copyright (c) 2004 by LLZQQ
# All rights reserved.
#
#ident "@(#)vsftpd 1.1 04/05/24"
case "$1" in
start)
/usr/sbin/vsftpd &
;;
stop)
pkill vsftpd
;;
*)
echo "Usage: $0 { start | stop }"
exit 1
;;
esac
exit 0
