Constructors

open

Signature	hs.network.configuration.open() -> storeObject
Type	Constructor
Description	Opens a session to the dynamic store maintained by the System Configuration server.
Parameters	None
Returns	the storeObject

Methods

computerName

Signature	hs.network.configuration:computerName() -> name, encoding
Type	Method
Description	Returns the name of the computeras specified in the Sharing Preferences, and its string encoding
Parameters	None
Returns	name - the computer name encoding - the encoding type
Notes	You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:/System")

consoleUser

Signature	hs.network.configuration:consoleUser() -> name, uid, gid
Type	Method
Description	Returns the name of the user currently logged into the system, including the users id and primary group id
Parameters	None
Returns	name - the user name uid - the user ID for the user gid - the user's primary group ID
Notes	You can also retrieve this information as key-value pairs with hs.network.configuration:contents("State:/Users/ConsoleUser")

contents

Signature	hs.network.configuration:contents([keys], [pattern]) -> table
Type	Method
Description	Return the contents of the store for the specified keys or keys matching the specified pattern(s)
Parameters	keys - a string or table of strings containing the keys or patterns of keys, if pattern is true. Defaults to all keys. pattern - a boolean indicating wether or not the string(s) provided are to be considered regular expression patterns (true) or literal strings to match (false). Defaults to false.
Returns	a table of key-value pairs from the dynamic store which match the specified keys or key patterns.
Notes	if no parameters are provided, then all key-value pairs in the dynamic store are returned.

dhcpInfo

Signature	hs.network.configuration:dhcpInfo([serviceID]) -> table
Type	Method
Description	Return the DHCP information for the specified service or the primary service if no parameter is specified.
Parameters	serviceID - an optional string contining the service ID of the interface for which to return DHCP info. If this parameter is not provided, then the default (primary) service is queried.
Returns	a table containing DHCP information including lease time and DHCP options
Notes	a list of possible Service ID's can be retrieved with hs.network.configuration:contents("Setup:/Network/Global/IPv4") generates an error if the service ID is invalid or was not assigned an IP address via DHCP.

hostname

Signature	hs.network.configuration:hostname() -> name
Type	Method
Description	Returns the current local host name for the computer
Parameters	None
Returns	name - the local host name
Notes	You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:/System")

keys

Signature	hs.network.configuration:keys([keypattern]) -> table
Type	Method
Description	Return the keys in the dynamic store which match the specified pattern
Parameters	keypattern - a regular expression specifying which keys to return (defaults to ".*", or all keys)
Returns	a table of keys from the dynamic store.

location

Signature	hs.network.configuration:location() -> location
Type	Method
Description	Returns the current location identifier
Parameters	None
Returns	location - the UUID for the currently active network location
Notes	You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:") If you have different locations defined in the Network preferences panel, this can be used to determine the currently active location.

locations

Signature	hs.network.configuration:locations() -> table
Type	Method
Description	Returns all configured locations
Parameters	None
Returns	a table of key-value pairs mapping location UUIDs to their names

monitorKeys

Signature	hs.network.configuration:monitorKeys([keys], [pattern]) -> storeObject
Type	Method
Description	Specify the key(s) or key pattern(s) to monitor for changes.
Parameters	keys - a string or table of strings containing the keys or patterns of keys, if pattern is true. Defaults to all keys. pattern - a boolean indicating wether or not the string(s) provided are to be considered regular expression patterns (true) or literal strings to match (false). Defaults to false.
Returns	the store Object
Notes	if no parameters are provided, then all key-value pairs in the dynamic store are monitored for changes.

proxies

Signature	hs.network.configuration:proxies() -> table
Type	Method
Description	Returns information about the currently active proxies, if any
Parameters	None
Returns	a table of key-value pairs describing the current proxies in effect, both globally, and scoped to specific interfaces.
Notes	You can also retrieve this information as key-value pairs with hs.network.configuration:contents("State:/Network/Global/Proxies")

setCallback

| Signature | hs.network.configuration:setCallback(function | nil) -> storeObject | | -----------------------------------------------------|---------------------------------------------------------------------------------------------------------| | Type | Method | | Description | Set or remove the callback function for a store object | | Parameters |

• a function or nil to set or remove the store object callback function

| | Returns |

• the store object

| | Notes |

• The callback function will be invoked each time a monitored key changes value and the callback function should accept two parameters: the storeObject itself, and an array of the keys which contain values that have changed.
• This method just sets the callback function. You specify which keys to watch with hs.network.configuration:monitorKeys and start or stop the watcher with hs.network.configuration:start or hs.network.configuartion:stop
