# Start of the optional stuff.

###########################################
# Optional: Turning on language extensions
#
# Instead of the default access control language that is documented in
# the hosts_access.5 document, the wrappers can be configured to
# implement an extensible language documented in the hosts_options.5
# document.  This language is implemented by the "options.c" source
# module, which also gives hints on how to add your own extensions.
# Uncomment the next definition to turn on the language extensions
# (examples: allow, deny, banners, twist and spawn).
# 
STYLE	= -DPROCESS_OPTIONS	# Enable language extensions.

################################################################
# Optional: Changing the default disposition of logfile records
#
# By default, logfile entries are written to the same file as used for
# sendmail transaction logs. See your /etc/syslog.conf file for actual
# path names of logfiles. The tutorial section in the README file
# gives a brief introduction to the syslog daemon.
# 
# Change the FACILITY definition below if you disagree with the default
# disposition. Some syslog versions (including Ultrix 4.x) do not provide
# this flexibility.
# 
# If nothing shows up on your system, it may be that the syslog records
# are sent to a dedicated loghost. It may also be that no syslog daemon
# is running at all. The README file gives pointers to surrogate syslog
# implementations for systems that have no syslog library routines or
# no syslog daemons. When changing the syslog.conf file, remember that
# there must be TABs between fields.
#
# The LOG_XXX names below are taken from the /usr/include/syslog.h file.

FACILITY= LOG_MAIL	# LOG_MAIL is what most sendmail daemons use

# The syslog priority at which successful connections are logged.

SEVERITY= LOG_INFO	# LOG_INFO is normally not logged to the console

######################################################
# Optional: Changing the default file protection mask
#
# On many systems, network daemons and other system processes are started
# with a zero umask value, so that world-writable files may be produced.
# It is a good idea to edit your /etc/rc* files so that they begin with
# an explicit umask setting.  On our site we use `umask 022' because it
# does not break anything yet gives adequate protection against tampering.
# 
# The following macro specifies the default umask for processes run under
# control of the daemon wrappers. Comment it out only if you are certain
# that inetd and its children are started with a safe umask value.

UMASK	= -DDAEMON_UMASK=022

#######################################
# Optional: Turning off access control
#
# By default, host access control is enabled.  To disable host access
# control, comment out the following definition.  Host access control
# can also be turned off at runtime by providing no or empty access
# control tables.

ACCESS	= -DHOSTS_ACCESS

####################################################
# Optional: dealing with host name/address conflicts
#
# By default, the software tries to protect against hosts that claim to
# have someone elses host name. This is relevant for network services
# whose authentication depends on host names, such as rsh and rlogin.
#
# With paranoid mode on, connections will be rejected when the host name
# does not match the host address. Connections will also be rejected when
# the host name is available but cannot be verified.
#
# Comment out the following definition if you want more control over such
# requests. When paranoid mode is off and a host name double check fails,
# the client can be matched with the PARANOID access control pattern.
#
# Paranoid mode implies hostname lookup. In order to disable hostname
# lookups altogether, see the next section.

PARANOID= -DPARANOID

# The default username lookup timeout is 10 seconds. This may not be long
# enough for slow hosts or networks, but is enough to irritate PC users.

RFC931_TIMEOUT = 10

########################################################
# Optional: Changing the access control table pathnames
#
# The HOSTS_ALLOW and HOSTS_DENY macros define where the programs will
# look for access control information. Watch out for the quotes and
# backslashes when you make changes.

TABLES	= -DHOSTS_DENY=\"/etc/hosts.deny\" -DHOSTS_ALLOW=\"/etc/hosts.allow\"

#############################################
# Optional: Turning on host ADDRESS checking
#
# Optionally, the software tries to protect against hosts that pretend to
# have someone elses host address. This is relevant for network services
# whose authentication depends on host names, such as rsh and rlogin,
# because the network address is used to look up the remote host name.
# 
# The protection is to refuse TCP connections with IP source routing
# options.
#
# This feature cannot be used with SunOS 4.x because of a kernel bug in
# the implementation of the getsockopt() system call. Kernel panics have
# been observed for SunOS 4.1.[1-3]. Symptoms are "BAD TRAP" and "Data
# fault" while executing the tcp_ctloutput() kernel function.
#
# Reportedly, Sun patch 100804-03 or 101790 fixes this for SunOS 4.1.x.
#
# Uncomment the following macro definition if your getsockopt() is OK.
#
# -DKILL_IP_OPTIONS is not needed on modern UNIX systems that can stop
# source-routed traffic in the kernel. Examples: 4.4BSD derivatives,
# Solaris 2.x, and Linux. See your system documentation for details.
#
# KILL_OPT= -DKILL_IP_OPTIONS

## End configuration options
