Attributes
-
default['nscd']['package']
- nscd package name, defaults tonscd
. Other variants include:unscd
,gnscd
-
default['nscd']['version']
- nscd version, defaults tonil
. If set tonil
, the latest will be installed.
The following attributes affect configuration of /etc/nscd.conf
.
* default['nscd']['logfile']
. Specifies name of the file to which debug info should be written. Default /var/log/nscd
* default['nscd']['threads']
. This is the number of threads that are started to wait for requests. At least five threads will always be created. Default 4
* default['nscd']['max_threads']
. Specifies the maximum number of threads. Default 32
* default['nscd']['server_user']
. If this option is set, nscd
will run as this user and not as root
. If a separate cache for every user is used (-S
parameter), this option is ignored. Default nscd
* default['nscd']['stat_user']
. Specifies the user who is allowed to request statistics. Default root
* default['nscd']['debug_level']
. Sets the desired debug level. Default 0
* default['nscd']['reload_count']
. Limit on the number of times a cached entry gets reloaded without being used before it gets removed. Default 5
* default['nscd']['paranoia']
. Enabling paranoia mode causes nscd
to restart itself periodically. Default no
* default['nscd']['restart_interval']
. Sets the restart interval to time seconds if periodic restart is enabled by enabling paranoia
mode. Default 3600
* default['nscd']['databases']
. List of databases to configure. Default %[passwd group hosts services netgroup
]
Each database has attributes, default depends on SERVICE
, see attribute file.
* default['nscd'][SERVICE]['enable_cache']
. Enables or disables the specified SERVICE
cache.
* default['nscd'][SERVICE]['positive_time_to_live']
. Sets the TTL (time-to-live) for positive entries (successful queries) in the specified cache for service. Value is in seconds. Larger values increase cache hit rates and reduce mean response times, but increase problems with cache coherence.
* default['nscd'][SERVICE]['negative_time_to_live']
. Sets the TTL (time-to-live) for negative entries (unsuccessful queries) in the specified cache for service. Value is in seconds. Can result in significant performance improvements if there are several files owned by UIDs (user IDs) not in system databases (for example untarring the Linux kernel sources as root); should be kept small to reduce cache coherency problems.
* default['nscd'][SERVICE]['suggested_size']
. This is the internal hash table size, value should remain a prime number for optimum efficiency.
* default['nscd'][SERVICE]['check_files']
. Enables or disables checking the file belonging to the specified service for changes. The files are /etc/passwd
, /etc/group
, /etc/hosts
, /etc/services
and /etc/netgroup
.
* default['nscd'][SERVICE]['persistent']
. Keep the content of the cache for service over server restarts; useful when paranoia
mode is set.
* default['nscd'][SERVICE]['shared']
. The memory mapping of the nscd
databases for service is shared with the clients so that they can directly search in them instead of having to ask the daemon over the socket each time a lookup is performed.
* default['nscd'][SERVICE]['max_db_size']
. The maximum allowable size, in bytes, of the database files for the service.
* default['nscd'][SERVICE]['auto_propagate']
. When set to no
for passwd
or group
service, then the .byname
requests are not added to passwd.byuid
or group.bygid
cache. This can help with tables containing multiple records for the same ID. This option is valid only for services passwd
and group
.
Recipes
default
Installs nscd, manages the nscd service and makes available commands to clear the nscd databases (passwd and group) so they can be notified in other recipes (such as when managing openldap).
Usage
If you're using nscd, add this recipe. If you need to notify the clear commands, e.g.,
cookbook_file '/etc/nsswitch.conf' do source 'nsswitch.conf' notifies :run, 'execute[nscd-clear-passwd]', :immediately notifies :run, 'execute[nscd-clear-group]', :immediately end
