NAME

Footprintless::Localhost - A localhost alias resolver

VERSION

version 1.29

DESCRIPTION

Provides a fairly thorough attempt to determine if a supplied hostname is an alias for localhost (resolves to the same physical machine). This can be useful in determining if local commands can be used in place of remote commands. This is primarily used by the Footprintless::CommandOptionsFactory to create appropriate command options for configured entities.

CONSTRUCTORS

new(%options)

Constructs a new Footprintless::Localhost preconfigured with the default aliases (localhost, 127.0.0.1). The available options are:

aliases

An initial set of preconfigured aliases that should resolve to localhost.

empty

Sets the value that will be returned if is_alias is called with a falsey value.

etc_hosts_file

Location of hosts file, defaults to /etc/hosts.

none

Stops the constructor from initializing the default aliases: localhost, 127.0.0.1.

METHODS

is_alias($hostname)

Returns a truthy value if $hostname is an alias for localhost.

is_loaded($source)

Returns a truthy value if $source has already been loaded. Each source is loaded using the load_$source method.

load_127_subnet()

Same effect as loading all 127.x.x.x addresses, but done with regex during call to is_alias.

load_all()

Loads aliases from all sources.

load_etc_hosts()

Loads aliases from the /etc/hosts file.

load_hostfqdn()

Loads aliases from the hostfqdn command.

load_hostname()

Loads aliases from the hostname command.
