# This is a basic ProFTPD configuration file (rename it to
# ‘proftpd.conf’ for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# “nobody” and “ftp” for normal operation and anon.
ServerName                      “ProFTPD centos”
ServerType                      standalone
DefaultServer                   on
# Port 21 is the standard FTP port.
Port                            21
# Don’t use IPv6 support by default.
# UseIPv6                               off
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask                           022
# To prevent DoS attacks, set the maximum number of child processes
# to 30.  If you need to allow more than 30 concurrent connections
# at once, simply increase this value.  Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).
MaxInstances                    30
# Set the user and group under which the server will run.
User                            proftpd
Group                           proftpd
# To cause every FTP user to be “jailed” (chrooted) into their home
# directory, uncomment this line.
#DefaultRoot ~
# Normally, we want files to be overwriteable.
AllowOverwrite          on
# Bar use of SITE CHMOD by default
<Limit SITE_CHMOD>
DenyAll
</Limit>
# A basic anonymous configuration, no upload directories.  If you do not
# want anonymous users, simply delete this entire <Anonymous> section.
<Anonymous /home/ftp>
User                          ftp
Group                         ftp
# We want clients to be able to login with “anonymous” as well as “ftp”
UserAlias                     anonymous ftp
# Limit the maximum number of anonymous logins
MaxClients                    10
# We want ‘welcome.msg’ displayed at login, and ‘.message’ displayed
# in each newly chdired directory.
DisplayLogin                  welcome.msg
DisplayChdir                  .message
# Limit WRITE everywhere in the anonymous chroot
<Limit WRITE>
DenyAll
