# If you want to run Pure-FTPd with this configuration   
# instead of command-line options, please run the
# following command :
#
# /usr/sbin/pure-config.pl /usr/etc/pure-ftpd.conf
#
# Please don't forget to have a look at documentation at
#
http://www.pureftpd.org/documentation.shtml
for a complete list of
# options.
# Cage in every user in his home directory
# 限定每一個使用者都只能在自己家目錄下活動。當設定成 no 時，則 Real User 可切換至其他
# 目錄做存取。
ChrootEveryone              no


# 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.
# 當您將註解拿掉後，GID 100 的群組成員會被視為信任的使用者，因此可以存取家目錄外的# 其他目錄。此時無論 ChrootEveryone 設定為何，都是一樣的結果。
# TrustedGID                    100

# Turn on compatibility hacks for broken clients

# Disallow anonymous connections. Only allow authenticated users.
NoAnonymous                 yes

# Syslog facility (auth, authpriv, daemon, ftp, security, user, local*)
# The default facility is "ftp". "none" disables logging.
# 您可以在 /etc/syslog.conf 裡使用 ftp 這個 facility，來告知 syslogd 要將 ftp 的相關訊息紀錄到
# 哪裡，比如： ftp.*　　 /var/log/ftplog

SyslogFacility              ftp

# Display fortune cookies
# FortunesFile              /usr/share/fortune/zippy

# 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,

# Minimum UID for an authenticated user to log in.
# 設定能允許 Real User 認證登入的最小 UID 為 100，也就是說 UID 100 以上 (含100) 的使用者方可認證登入。# 如您欲允許 root 登入的話，這個地方請註解起來，並且在 /etc/ftpusers 檔案中將 root 帳號移除。
# /etc/ftpusers 是用來設定拒絕登入 FTP Server 的使用者名單的。

# Allow FXP transfers for authenticated users.
AllowUserFXP                yes
# Allow anonymous FXP for anonymous and non-anonymous users.

ProhibitDotFilesWrite       yes
# Prohibit *reading* of files beginning with a dot (.history, .ssh...)

# 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 : :
# 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

上面的設定可以同時接受真實的帳號及虛擬的ftp 帳號登入使用
真實的帳號可以變更所在目錄
虛擬的ftp帳號則不能變更目錄


新增專屬的主要群組

groupadd virtualgrp

建立 ftp 專屬帳號
useradd -g virtualgrp -m virtualuser
使用 pure-pw 指令來建立虛擬的ftp帳號: adam

pure-pw useradd adam -u virtualuser -d /home/virtualuser/adam -m

未來如果有直接異動 /etc/pure-ftpd/pureftpd.passwd 的時候，需要執行以下的命令，來更新資料庫的內容

pure-pw mkdb

啟動pure-ftpd
/etc/init.d/pure-ftpd start

以下的指令可以看到使用者的設定資料
pure-pw show adam

pure-pw usermod adam -t 100 -T 50 -q 1 -Q 10 -n 30 -N 2 \
> -z 1400-2230 -r 192.168.5.0/24,192.168.1.0/24 -m


#參數格式
       pure-pw usermod login -f passwd_file -u uid [-g gid]
                       -D/-d home_directory -[c gecos]
                       [-t download_bandwidth] [-T upload_bandwidth]
                       [-n max_number_of_files] [-N max_Mbytes]

                       [-y ]
                       [-z -] [-m]
#參數說明
# -t, -T: 設定下載及上傳的頻寬
# -q, -Q: 設定下載及上傳的比率
# -n :設定可以使用的檔案數
# -N :限制可以使用的空間大小 (MB)
# -z : 限定連線時間
# -r : 允許存取的來源端
修改 adam 的密碼
pure-pw passwd adam -m
刪除 adam 的帳繞
pure-pw userdel adma -m
