# Enable virtual quotas. The first value is the max number of files.
# The second value is the maximum size, in 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.
# Don't enable this option if you don't actually use pure-uploadscript.

# CallUploadScript             yes

# This option is useful on servers where anonymous upload is
# allowed. When the partition is more that percententage full,
# new uploads are disallowed.

MaxDiskUsage                   99

# Set to 'yes' to prevent users from renaming files.

# NoRename                     yes

# Be 'customer proof': forbids common customer mistakes such as
# 'chmod 0 public_html', that are valid, but can cause customers to
# unintentionally shoot themselves in the foot.

CustomerProof                yes

# Per-user concurrency limits. Will only work if the FTP server has
# been compiled with --with-peruserlimits.
# Format is: <max sessions per user>:<max anonymous sessions>
# For example, 3:20 means that an authenticated user can have up to 3 active
# sessions, and that up to 20 anonymous sessions are allowed.

# PerUserLimits                3:20

# When a file is uploaded and there was already a previous version of the file
# with the same name, the old file will neither get removed nor truncated.
# The file will be stored under a temporary name and once the upload is
# complete, it will be atomically renamed. For example, when a large PHP
# script is being uploaded, the web server will keep serving the old version and
# later switch to the new one as soon as the full file will have been
# transferred. This option is incompatible with virtual quotas.

# NoTruncate                   yes

# This option accepts three values:
# 0: disable SSL/TLS encryption layer (default).
# 1: accept both cleartext and encrypted sessions.
# 2: refuse connections that don't use the TLS security mechanism,
#    including anonymous sessions.
# Do _not_ uncomment this blindly. Double check that:
# 1) The server has been compiled with TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.

# TLS                          1

# Cipher suite for TLS sessions.
# The default suite is secure and setting this property is usually
# only required to *lower* the security to cope with legacy clients.
# Prefix with -C: in order to require valid client certificates.
# If -C: is used, make sure that clients' public keys are present on
# the server.

# TLSCipherSuite               HIGH

# Certificate file, for TLS
# The certificate itself and the keys can be bundled into the same
# file or split into two files.
# CertFile is for a cert+key bundle, CertFileAndKey for separate files.
# Use only one of these.

# CertFile                     /etc/ssl/private/pure-ftpd.pem
# CertFileAndKey               "/etc/pure-ftpd.pem" "/etc/pure-ftpd.key"

# Unix socket of the external certificate handler, for TLS

# ExtCert                      /var/run/ftpd-certs.sock

# 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 (i.e. disable IPv4)
# By default, both IPv4 and IPv6 are enabled.

# IPV6Only                     yes

# Append the content of another file, if the file exists.
# If the file doesn't exist, the directive is ignored.
# More files can be recursively included.

# Include                      additional_configuration.conf
