# ACCESS.ALLOW - Game access allowance rules
#----------------------------------------------------------------------------
# Access to the game is based on the user's IP address and the current time.
# These are matched against a set of rules and if a match is detected, a
# proper message is sent back and the connection is shutdown.
#
# This facility is active only if ACCESS_CONTROL has been defined in config.h
# If ACCESS_LOG is defined in config.h, all checks and their results are
# logged in the specified file.
#
# The rules are read from the file ACCESS_FILE (defined in config.h,
# typically "ACCESS.ALLOW" with a name relative to the mudlib directory).
# Every line specifies one rule and has to follow the syntax given below.
# Lines with a '#' as first character count as comments and are ignored, as
# are lines which do not conform to the rule syntax (but except for empty
# lines this should be relied upon).
#
# The rule file is (re)read whenever the gamedriver detects a change in its
# timestamp.
#
# The syntax for a rule is (no leading whitespace allowed!):
#
#   <ipnum>:[p<port>]:<class>:<max>:<start>:<end>:<text>
#   <ipnum>:[p<port>]:<class>:<max>:h<hours>:w<days>:m=<text>
#
# where
#   ipnum:  <byte>.<byte>.<byte>.<byte>, with byte = * or number
#             There is only loose error checking - specifying an illegal
#             address will have interesting consequences, but would
#             most likely cause no error to occur.
#   port:   the port number to which the connection is made. Omission
#             means 'any port'.
#   class:  number
#   max:    the maximum number of users, a number. The value -1 allows
#             an unlimited number of users.
#   start:  hour this rule starts to be valid (0..23).
#   end:    hour this rule ceases to be valid (0..23).
#             Setting both start and end to 0 skips any time check.
#   hours:  hours this rule is valid.
#             This form allows several entries, separated with a ','.
#             Every entry can be a single hour (0..23), or a range in the
#             form '<start>-<end>'
#             Omitting the entry skips any time check.
#   days:   the days this rule is valid.
#             The syntax is similar to <hours> except for the
#             allowable values: the days Sunday..Saturday are given as
#             the numbers 0..6.
#             Omitting the entry skips any day check.
#   text:   string to send if the rule matches.
#
# A class is defined by the first rule using it's number. This
# definition specifies the allowable <max>imum of users and the <text>
# to send. Subsequent rules for the same class just add new ipnumber/
# time rules, but don't change <max> or <text>
#
# ORDER MATTERS. That means if you allow 129.*.*.*, you have to put
# any restrictions on 129.132.*.* BEFORE this rule.
#
# Addresses not matching any rule at all are not allowed to connect.  To get
# around this, add an appropriate 'allow-all' rule *.*.*.* at the very end.
#
# A typical rulefile would look like this one:

# SPARC cluster has access denied. Class 1
129.132.122.*:1:0:0:0:LPMUD access denied for your cluster.

# CALL-1A0 has access limited to some maximum, for now 5 logins. Class 2
129.132.106.*:2:5:8:20:Sorry, LPMUD is currently full.

# CALL-1A0 at all other times, its a 10 limit.
#   Due to the rule order, this is effectively limited to times
#   outside 8-20.
129.132.106.*:3:10:0:0:Sorry, LPMUD is currently full.

# No more than 5 users allowed from localhost while working hours :-)
127.0.0.1:42:5:h8-12,13-18:w1-5:m=Pick a better time.

# Everybody else is welcome.
*.*.*.*:0:-1:0:0:This message should never be printed.
