here is my proftpd file
# 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.
# Allow FTP resuming.
# Remember to set to off if you have an incoming ftp for upload.
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
# 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).
# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
# Normally, we want files to be overwriteable.
# Bar use of SITE CHMOD by default
# Needed for NIS.
# A basic anonymous configuration, no upload directories.
# Allow masquerading and use of port 8889 from Internet.

# We want clients to be able to login with "anonymous" as well as "ftp"
UserAlias anonymous ftp
# Limit the maximum number of anonymous logins
# Don't make it require a valid password or shell.
# Limit WRITE everywhere in the anonymous chroot
