NAME
App::Netdisco::Util::Device
DESCRIPTION
A set of helper subroutines to support parts of the Netdisco application.
There are no default exports, however the :all tag will export all subroutines.
EXPORT_OK
get_device( $ip )
Given an IP address, returns a DBIx::Class::Row object for the Device in the Netdisco database. The IP can be for any interface on the device.
If for any reason $ip is already a DBIx::Class Device object, then it is simply returned.
If the device or interface IP is not known to Netdisco a new Device object is created for the IP, and returned. This object is in-memory only and not yet stored to the database.
check_device_no( $ip, $setting_name )
Given the IP address of a device, returns true if the configuration setting $setting_name matches that device, else returns false. If the setting is undefined or empty, then check_no also returns false.
print "rejected!" if check_no($ip, 'discover_no');There are several options for what $setting_name can contain:
Hostname, IP address, IP prefix
IP address range, using a hyphen and no whitespace
Regular Expression in YAML format which will match the device DNS name, e.g.:
- !!perl/regexp ^sep0.*$"model:regex"- matched against the device model"vendor:regex"- matched against the device vendor
To simply match all devices, use "any" or IP Prefix "0.0.0.0/0". All regular expressions are anchored (that is, they must match the whole string). To match no devices we recommend an entry of "localhost" in the setting.
check_device_only( $ip, $setting_name )
Given the IP address of a device, returns true if the configuration setting $setting_name matches that device, else returns false. If the setting is undefined or empty, then check_only also returns true.
print "rejected!" unless check_only($ip, 'discover_only');There are several options for what $setting_name can contain:
Hostname, IP address, IP prefix
IP address range, using a hyphen and no whitespace
Regular Expression in YAML format which will match the device DNS name, e.g.:
- !!perl/regexp ^sep0.*$"model:regex"- matched against the device model"vendor:regex"- matched against the device vendor
To simply match all devices, use "any" or IP Prefix "0.0.0.0/0". All regular expressions are anchored (that is, they must match the whole string). To match no devices we recommend an entry of "localhost" in the setting.
is_discoverable( $ip, $device_type? )
Given an IP address, returns true if Netdisco on this host is permitted by the local configuration to discover the device.
The configuration items discover_no and discover_only are checked against the given IP.
If $device_type is also given, then discover_no_type will also be checked.
Returns false if the host is not permitted to discover the target device.
is_arpnipable( $ip )
Given an IP address, returns true if Netdisco on this host is permitted by the local configuration to arpnip the device.
The configuration items arpnip_no and arpnip_only are checked against the given IP.
Returns false if the host is not permitted to arpnip the target device.
is_macsuckable( $ip )
Given an IP address, returns true if Netdisco on this host is permitted by the local configuration to macsuck the device.
The configuration items macsuck_no and macsuck_only are checked against the given IP.
Returns false if the host is not permitted to macsuck the target device.
