# 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 /etc/pure-ftpd/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.

#限制所有用户只能访问主目录
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.
#信任组ID，不用设置，注释掉
# TrustedGID                    100

# 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
#运行时的pid路径
#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.
# Don't enable this option if you don't actually use pure-uploadscript.
# 如果你的 pure-ftpd 编译时加入了 pure-uploadscript 支持，这个指令将会使 pure-ftpd
# 发送关于新上传的情况信息到 /var/run/pure-ftpd.upload.pipe，这样 pure-uploadscript
# 就能读然后调用一个脚本去处理新的上传。
#这个功能用好了可以做很多事。。。

#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.
#限定上传文件占用硬盘的极限值，超过后不再接收上传数据
MaxDiskUsage               99



# Set to 'yes' if you don't want your users to rename files.
#是否禁止用户重命名已存在的文件
NoRename                  no



# 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.
#设置为yes，防止chmod修改错误导致文件锁定
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.
#3:20 意思是同一个认证用户最大可以有3个同时活动的进程。而且同时最多只能有20个匿名用户进程。
# 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
# yes文件相同直接删除旧的，no先保留再更新
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


# OpenSSL ciphers suite for TLS sessions.
# Prefix with -C: in order to require valid client certificates.
# If -C: is used, make sure that clients' public keys are installed
# on the server.
# SSL is disabled by default. TLS 1.0, 1.1 and 1.2 are available by
# default.

# TLSCipherSuite           HIGH



# Certificate file, for TLS

# CertFile                 /etc/ssl/private/pure-ftpd.pem



# Listen only to IPv4 addresses in standalone mode (ie. disable IPv6)
# By default, both IPv4 and IPv6 are enabled.
#只允许IPV4连接
IPV4Only                 yes



# Listen only to IPv6 addresses in standalone mode (ie. disable IPv4)
# By default, both IPv4 and IPv6 are enabled.

# IPV6Only                 yes

# UTF-8 support for file names (RFC 2640)
# Define charset of the server filesystem and optionnally the default charset
# for remote clients if they don't use UTF-8.
# Works only if pure-ftpd has been compiled with --with-rfc2640
