经验与技巧：在SOLARIS上编译安装VSFTPD

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

　　5． 建立VSFTPD的启动脚本

　　# vi /etc/rc3.d/S83vsftpd

　　================================= S83vsftpd ============================

　　#!/sbin/sh
