# Choice between easy and advanced installation recipe.
# 
# Advanced installation: vendor-provided daemons are left alone, and the
# inetd configuration file is edited. In this case, the REAL_DAEMON_DIR
# macro should reflect the actual directory with (most of) your
# vendor-provided network daemons.  These names can be found in the
# inetd.conf file. Usually, the telnet, ftp and finger daemons all live
# in the same directory.
# 
# Uncomment the appropriate line if you are going to edit inetd.conf.

# Easy installation: vendor-provided network daemons are moved to "some
# other" directory, and the tcpd wrapper fills in the "holes". For this
# mode of operation, the REAL_DAEMON_DIR macro should be set to the "some
# other" directory.  The "..." is here for historical reasons only; you
# should probably use some other name.

# above, do a "make sunos4" (or whatever system type is appropriate).
#
# If your system is not listed (or something that comes close enough), you
# have to edit the system dependencies section below and do a "make other".

##############################
# 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_AUTH	# 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: Reduce DNS load
#
# When looking up the address for a host.domain name, the typical DNS
# code will first append substrings of your own domain, so it tries
# host.domain.your.own.domain, then host.domain.own.domain, and then
# host.domain. The APPEND_DOT feature stops this waste of cycles. It is
# off by default because it causes problems on sites that don't use DNS
# and with Solaris < 2.4.
#
# DOT= -DAPPEND_DOT

##################################################
# Optional: Always attempt remote username lookups
#
# By default, the wrappers look up the remote username only when the
# access control rules require them to do so.
#
# Username lookups require that the remote host runs a daemon that
# supports an RFC 931 like protocol.  Remote user name lookups are not
# possible for UDP-based connections, and can cause noticeable delays
# with connections from non-UNIX PCs.  On some systems, remote username
# lookups can trigger a kernel bug, causing loss of service. The README
# file describes how to find out if your UNIX kernel has that problem.
# 
# Uncomment the following definition if the wrappers should always
# attempt to get the remote user name. If this is not enabled you can
# still do selective username lookups as documented in the hosts_access.5
# and hosts_options.5 manual pages (`nroff -man' format).
#
#AUTH	= -DALWAYS_RFC931
#
# 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 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: 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: 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

########################################
# Optional: turning off hostname lookups
#
# By default, the software always attempts to look up the client
# hostname.  With selective hostname lookups, the client hostname
# lookup is postponed until the name is required by an access control
# rule or by a %letter expansion.
# 
# In order to perform selective hostname lookups, disable paranoid
# mode (see previous section) and comment out the following definition.

HOSTNAME= -DALWAYS_HOSTNAME

#############################################
# 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 effective only when the offending host claims to have
# a network address that lies outside its own network.
#
# My site has been running rlogind and rshd daemons that implement this
# feature for more than 2 years, and without any ill effects.
#
# 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.
#
# KILL_OPT= -DKILL_IP_OPTIONS
