# Warning: this file will be overridden by further installations.
# You can copy this file to another location and use it as as a template to 
# create your own cutomized netcd configuration.
# If you do not use any configuration files, netcd proceeds with the 
# default values indicated.
#
# There are 4 types of declarations :
# 1- cache description declarations (keyword - "cache")
# 2- security declarations (keywords - "owner", "group" and "home_dir")
# 3- log file declarations (keywords - "log_file", "log_rotate", "log_size")
# 4- additional declarations to control the netcd daemon (keywords - "net_scan_frequency",
# "local_scan_frequency", "socket_queue_size")
#
# The general syntax is : keyword followed by one or more space or tab followed 
# by a string of characters.
# The syntax for each individual keyword is described below.
#
# 1- cache description declarations
# 0 to n "cache" lines describe what will be cached
# Syntax is :
# cache  <type_of_cache>  <type_of_map>  <hash_size>  <cache_ttl>
# 
# If no such line is specified, the default line is
# cache  all   all    128  60
#
# <type_of_cache> can have the values : "local", "dns", "nis", "nisplus", "yp", "ulm", 
# "all", or a ulm name.
# Any string other than "local", "dns", "nis", "nisplus", "yp", "ulm", "all" will be 
# taken as a ulm name. Up to 16 ulms can be declared.
#
# <type_of_map> can have the values : "hosts", "protocols", "services", 
# "networks", "netgroup", "all" or a yp map name.
# The map types supported for "local", "nis", "nisplus" and ulm resolutions are : 
# "hosts", "services", "protocols", "networks", "netgroup".
# For the "dns" cache, "hosts" is the only map supported.
# The map types supported for "yp" are : "passwd.byname", "passwd.byuid", 
# "group.byname", "group.bygid", "netid.byname", "passwd.adjunct.byname".
#
# <hash_size> is the number of lines for the cache (a cache being a hash table); 
# default is 128.
#
# <cache_ttl> is the length of time during which an entry will be kept in the cache; 
# unit is minutes; 0 is infinite; default : 60; 
# <cache_ttl> is not be taken into account for local caches.
# For dns, we recommand not to specify this parameter or to set it to 0. 
# In case of dns, if a non null value is specified, it will overwrite the dns ttl 
# sent back if the entry was found by dns; otherwise, each entry is kept in the cache
# for the duration of the ttl specified by the dns.

# For dns, netcd daemon also support <negative_cache_ttl> value. If negative_cache_ttl value is specified
# then it will overwrite the the dns negative response ttl value. Below is the syntax.
# cache <type_of_cache> <type_of_map> <hash_size> <cache_ttl>:<negative_cache_ttl>
# All combination can be interpreted as
# 1- cache dns hosts 128               obey the ttl from dns server for positive and negative responses
# 2- cache dns hosts 128 20            overwrite the ttl from dns server for positive and negative responses
# 3- cache dns hosts 128 20:30         overwrite the ttl from dns server for positive and negative
#                                      responses with different ttl values
# 4- cache dns hosts 128 0:20          overwrite the ttl from dns server for negative response only
# 5- cache dns hosts 128 20:0          overwrite the ttl from dns server for positive response only

# example of cache declaration to cache only local hosts resolution with a hash 
# table of 1024 lines :
# cache   local   hosts   1024
#
# example of cache declaration to cache all the local resolutions with caches 
# of 512 lines :
# cache  local  all  512
#
# example of cache declaration for all protocols resolution with a hash table of 
# 600 lines with an expiration of 1 day :
# cache  all  protocols   600  1440
#
# example of cache declaration for "david" ulm for all maps with a hash table of 
# 128 lines with by default an expiration of 1 hour :
# cache david   all 128
#
# 
# 2- security declarations
# These 3 following declarations allow netcd to run in secure 
# mode (e.g. security against code execution due to stack overflow)
# owner      <value>    
# specify the owner of netcd during its execution
# default "root"
#
# group      <value>    
# specify the group owner of netcd during its execution
# default "system"
#
# home_dir   <value>    
# specify the working directory for netcd during its execution
# default "/"
#
# 
# 3- log file description
# log_file <file>      
# specify the name of the log file for netcd
# default "/var/tmp/netcd.log"
#
# log_rotate <number>  
# number of rotations for log file
# default is no rotation.
#
# log_size <number>    
# size of log file in case of rotation (in KB)
#
# 
# 4- additional declarations
# net_scan_frequency      <value>   
# specify the scan frequency of the network cache for expired entries due to ttl
# default : 1
# net_scan_frequency is expressed in minutes
#
# local_scan_frequency    <value>  
# specify the scan frequency of the local files for modified dates
# when a local file (e.g. /etc/hosts) is detected as modified, the corresponding
# local cahe is reloaded with the content of the file.
# default : 1
# local_scan frequency is expressed in minutes
# 
# socket_queue_size      <value>  
# Size of message queue for the socket used by netcd to communicate with the 
# requesting applications; indicate how many waiting requests the netcd 
# daemon will accept
# default is 256
#
