89# Optional: Turning on language extensions
90#
91# Instead of the default access control language that is documented in
92# the hosts_access.5 document, the wrappers can be configured to
93# implement an extensible language documented in the hosts_options.5
94# document.  This language is implemented by the "options.c" source
95# module, which also gives hints on how to add your own extensions.
96# Uncomment the next definition to turn on the language extensions
97# (examples: allow, deny, banners, twist and spawn).
98#
99STYLE	= -DPROCESS_OPTIONS	# Enable language extensions.

102# Optional: Changing the default disposition of logfile records
103#
104# By default, logfile entries are written to the same file as used for
105# sendmail transaction logs. See your /etc/syslog.conf file for actual
106# path names of logfiles. The tutorial section in the README file
107# gives a brief introduction to the syslog daemon.
108#
109# Change the FACILITY definition below if you disagree with the default
110# disposition. Some syslog versions (including Ultrix 4.x) do not provide
111# this flexibility.
112#
113# If nothing shows up on your system, it may be that the syslog records
114# are sent to a dedicated loghost. It may also be that no syslog daemon
115# is running at all. The README file gives pointers to surrogate syslog
116# implementations for systems that have no syslog library routines or
117# no syslog daemons. When changing the syslog.conf file, remember that
118# there must be TABs between fields.
119#
120# The LOG_XXX names below are taken from the /usr/include/syslog.h file.
121
122FACILITY= LOG_MAIL	# LOG_MAIL is what most sendmail daemons use
123
124# The syslog priority at which successful connections are logged.

126SEVERITY= LOG_INFO	# LOG_INFO is normally not logged to the console
127
128######################################################
129# Optional: Changing the default file protection mask
130#
131# On many systems, network daemons and other system processes are started
132# with a zero umask value, so that world-writable files may be produced.
133# It is a good idea to edit your /etc/rc* files so that they begin with
134# an explicit umask setting.  On our site we use `umask 022' because it
135# does not break anything yet gives adequate protection against tampering.
136#
137# The following macro specifies the default umask for processes run under
138# control of the daemon wrappers. Comment it out only if you are certain
139# that inetd and its children are started with a safe umask value.
140
141UMASK	= -DDAEMON_UMASK=022

143#######################################
144# Optional: Turning off access control
145#
146# By default, host access control is enabled.  To disable host access
147# control, comment out the following definition.  Host access control
148# can also be turned off at runtime by providing no or empty access
149# control tables.
150
151ACCESS	= -DHOSTS_ACCESS
152
153####################################################
154# Optional: dealing with host name/address conflicts
155#
156# By default, the software tries to protect against hosts that claim to
157# have someone elses host name. This is relevant for network services
158# whose authentication depends on host names, such as rsh and rlogin.
159#
160# With paranoid mode on, connections will be rejected when the host name
161# does not match the host address. Connections will also be rejected when
162# the host name is available but cannot be verified.
163#
164# Comment out the following definition if you want more control over such
165# requests. When paranoid mode is off and a host name double check fails,
166# the client can be matched with the PARANOID access control pattern.
167#
168# Paranoid mode implies hostname lookup. In order to disable hostname
169# lookups altogether, see the next section.
170
171PARANOID= -DPARANOID
172
173# The default username lookup timeout is 10 seconds. This may not be long
174# enough for slow hosts or networks, but is enough to irritate PC users.
175

177
178########################################################
179# Optional: Changing the access control table pathnames
180#
181# The HOSTS_ALLOW and HOSTS_DENY macros define where the programs will
182# look for access control information. Watch out for the quotes and
183# backslashes when you make changes.
184
185TABLES	= -DHOSTS_DENY=\"/etc/hosts.deny\" -DHOSTS_ALLOW=\"/etc/hosts.allow\"
186
187#############################################
188# Optional: Turning on host ADDRESS checking
189#
190# Optionally, the software tries to protect against hosts that pretend to
191# have someone elses host address. This is relevant for network services
192# whose authentication depends on host names, such as rsh and rlogin,
193# because the network address is used to look up the remote host name.
194#
195# The protection is to refuse TCP connections with IP source routing
196# options.
197#
198# This feature cannot be used with SunOS 4.x because of a kernel bug in
199# the implementation of the getsockopt() system call. Kernel panics have
200# been observed for SunOS 4.1.[1-3]. Symptoms are "BAD TRAP" and "Data
201# fault" while executing the tcp_ctloutput() kernel function.
202#
203# Reportedly, Sun patch 100804-03 or 101790 fixes this for SunOS 4.1.x.
204#
205# Uncomment the following macro definition if your getsockopt() is OK.
206#
207# -DKILL_IP_OPTIONS is not needed on modern UNIX systems that can stop
208# source-routed traffic in the kernel. Examples: 4.4BSD derivatives,
209# Solaris 2.x, and Linux. See your system documentation for details.
210#
211# KILL_OPT= -DKILL_IP_OPTIONS
