ServerAdmin			root@localhost
DefaultServer			on

# Cause every FTP user except adm to be chrooted into their home directory
# Aliasing /etc/security/pam_env.conf into the chroot allows pam_env to

# Use pam to authenticate (default) and be authoritative
AuthPAMConfig			proftpd
AuthOrder			mod_auth_pam.c* mod_auth_unix.c
# If you use NIS/YP/LDAP you may need to disable PersistentPasswd
#PersistentPasswd		off

# Don't do reverse DNS lookups (hangs on DNS problems)
UseReverseDNS			off

# Set the user and group that the server runs as
User				nobody
Group				nobody

# To prevent DoS attacks, set the maximum number of child processes
# to 20.  If you need to allow more than 20 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			20

# Disable sendfile by default since it breaks displaying the download speeds in
# ftptop and ftpwho
UseSendfile			off

# Define the log formats
LogFormat			default	"%h %l %u %t \"%r\" %s %b"
LogFormat			auth	"%v [%P] %h %t \"%r\" %s"
