研究freebsd 已有几个月了。但一直没有找到一个比Windows下的serv-u 易管理的
ftp 服务器软件。前一段服务器都是用vsftpd＋系统quota ， 但帐号是系统本身帐号。虽然，我做了
/sbin/nologin
但感觉还是不安全。也试过。proftpd+mysql ，但如果一个企业就开ftp,你要和系统帐号分离，难道还要
装mysql,等等数据库不成？
下面我就把我pureftpd 配置写出来。本人是菜鸟，哪地方不对希望高手多多指点！
我都是都过ports 方式安装的
freebsd# cd /usr/ports/ftp/pure-ftpd/
默认ports 安装pure-ftpd 不支持 puredb 需要
freebsd# vi Makefile
加入 --with-puredb
然后wq!
freebsd# make WITH_LANG=simplifIEd-chinese install
建立第一个虚拟用户：如down 用户，组都为888 主目录/home/888
freebsd# mkdir /home/888
freebsd# chown -R 888:888 /home/888
freebsd# /usr/local/bin/pure-pw useradd down -u 888 -g 888 -d /home/888
PassWord: 输入二次
Enter it again:
建立用户数据库：
freebsd# /usr/local/bin/pure-pw mkdb /usr/local/etc/pureftpd.pdb
修改配置文件。
freebsd# cd /usr/local/etc/
freebsd# cp pure-ftpd.conf.sample pure-ftpd.conf
找到# PureDB /etc/pureftpd.pdb
把#掉支掉，路径改成你刚才建的。 我的是/usr/local/etc/pureftpd.pdb
启动pureftpd 。。
freebsd# /usr/local/sbin/pure-config.pl /usr/local/etc/pure-ftpd.conf
D:>ftp 218.*.*.*
Connected to *.*.*.*
220---------- 欢迎来到 Pure-FTPd [TLS] ----------
220-您是第 1 个使用者，最多可达 50 个连接
220-现在本地时间是 13:20。服务器端口： 21。
220 在 15 分钟内没有活动，您被会断线。
User (218.*.*.*:(none)):
好了。就这么简单。就和系统帐号完全分离了。如果你想即系统帐号又和puredb 帐号同时使用
在pure-ftpd.conf 打开UnixAuthentication yes
些项即可。自启动把/usr/local/etc/rc.d/pure-ftpd.sh.sample 改名cp 去掉.sample 即可。其实还有
很多比如quota ，好多，你们慢慢研究吧！最后把我的pureftpd 给大家看一看。

############################################################
# If you want to run Pure-FTPd with this configuration
# instead of command-line options, please run the
# following command :
#
# /usr/local/sbin/pure-config.pl /usr/local/etc/pure-ftpd.conf
#
# Please don't forget to have a look at documentation at
# http://www.pureftpd.org/documentation.HTML for a complete list of
# options.
# Cage in every user in his home Directory
ChrootEveryone yes
# If the previous option is set to "no", members of the following group
# won't be caged. Others will be. If you don't want chroot()ing anyone,
# just comment out ChrootEveryone and TrustedGID.
# TrustedGID 100
# Turn on compatibility hacks for broken clients
BrokenClientsCompatibility no
# Maximum number of simultaneous users
MaxClientsNumber 50
# Fork in background
Daemonize yes
# Maximum number of sim clients with the same IP address

# If you want to log all client commands, set this to "yes".
# This directive can be duplicated to also log server responses.
VerboseLog no
# List dot-files even when the client doesn't send "-a".
DisplayDotFiles yes
# Don't allow authenticated users - have a public anonymous FTP only.
AnonymousOnly no
# Disallow anonymous connections. Only allow authenticated users.
NoAnonymous no
# Syslog facility (auth, authpriv, daemon, ftp, security, user, local*)
# The default facility is "ftp". "none" disables logging.
SyslogFacility ftp
# Display fortune cookies
# FortunesFile /usr/share/fortune/zippy
# Don't resolve host names in log files. Logs are less verbose, but
# it uses less bandwidth. Set this to "yes" on very busy servers or

# If you want simple Unix (/etc/passwd) authentication, uncomment this
UnixAuthentication yes
# Please note that LDAPConfigFile, MySQLConfigFile, PAMAuthentication and
# UnixAuthentication can be used only once, but they can be combined
# together. For instance, if you use MySQLConfigFile, then UnixAuthentication,
# the SQL server will be asked. If the SQL authentication fails because the
# user wasn't found, another try # will be done with /etc/passwd and
# /etc/shadow. If the SQL authentication fails because the password was wrong,
# the authentication chain stops here. Authentication methods are chained in
# the order they are given.
# 'ls' recursion limits. The first argument is the maximum number of

AutoRename no
# Disallow anonymous users to upload new files (no = upload is allowed)
AnonymousCantUpload no
# Only connections to this specific IP address are allowed to be
# non-anonymous. You can use this directive to open several public IPs for
# anonymous FTP, and keep a private firewalled IP for remote administration.
# You can also only allow a non-routable local IP (like 10.x.x.x) to
# authenticate, and keep a public anon-only FTP server on another IP.
#TrustedIP 10.1.1.1
# If you want to add the PID to every logged line, uncomment the following
# line.
#LogPID yes
# Create an additional log file with transfers logged in a Apache-like format :
# fw.c9x.org - jedi [13/Dec/1975:19:36:39] "GET /ftp/Linux.tar.bz2" 200 21809338
# This log file can then be processed by www traffic analyzers.
# AltLog clf:/var/log/pureftpd.log
# Create an additional log file with transfers logged in a format optimized
# for statistic reports.
# AltLog stats:/var/log/pureftpd.log
# Create an additional log file with transfers logged in the standard W3C
# format (compatible with most commercial log analyzers)
# AltLog w3c:/var/log/pureftpd.log
# Disallow the CHMOD command. Users can't change perms of their files.
#NoChmod yes
# Allow users to resume and upload files, but *NOT* to delete them.
#KeepAllFiles yes
# Automatically create home directories if they are missing
#CreateHomeDir yes
# Enable virtual quotas. The first number is the max number of files.
# The second number is the max size of megabytes.
# So 1000:10 limits every user to 1000 files and 10 Mb.
#Quota 1000:10
# If your pure-ftpd has been compiled with standalone support, you can change
# the location of the pid file. The default is /var/run/pure-ftpd.pid
#PIDFile /var/run/pure-ftpd.pid
# If your pure-ftpd has been compiled with pure-uploadscript support,
# this will make pure-ftpd write info about new uploads to
# /var/run/pure-ftpd.upload.pipe so pure-uploadscript can read it and
# spawn a script to handle the upload.
#CallUploadScript yes
# This option is useful with servers where anonymous upload is
# allowed. As /var/ftp is in /var, it save some space and protect
# the log files. When the partition is more that X percent full,
# new uploads are disallowed.
MaxDiskUsage 99
# Set to 'yes' if you don't want your users to rename files.
#NoRename yes
# Be 'customer proof' : workaround against common customer mistakes like
# 'chmod 0 public_html', that are valid, but that could cause ignorant
# customers to lock their files, and then keep your technical support busy
# with silly issues. If you're sure all your users have some basic Unix
# knowledge, this feature is useless. If you're a hosting service, enable it.
CustomerProof yes
# Per-user concurrency limits. It will only work if the FTP server has
# been compiled with --with-peruserlimits (and this is the case on
# most binary distributions) .
# The format is : <max sessions per user>:<max anonymous sessions>
# For instance, 3:20 means that the same authenticated user can have 3 active
# sessions max. And there are 20 anonymous sessions max.
# PerUserLimits 3:20
# When a file is uploaded and there is already a previous version of the file
# with the same name, the old file will neither get removed nor truncated.
# Upload will take place in a temporary file and once the upload is complete,
# the switch to the new version will be atomic. For instance, when a large PHP
# script is being uploaded, the web server will still serve the old version and
# immediatly switch to the new one as soon as the full file will have been
# transfered. This option is incompatible with virtual quotas.
# NoTruncate yes
# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
# including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.
# TLS 1
# Listen only to IPv4 addresses in standalone mode (ie. disable IPv6)
# By default, both IPv4 and IPv6 are enabled.
# IPV4Only yes
# Listen only to IPv6 addresses in standalone mode (ie. disable IPv4)
# By default, both IPv4 and IPv6 are enabled.
# IPV6Only yes
