Helper subroutines to support parts of the Netdisco application.
There are no default exports, however the
:all tag will export all subroutines.
check_acl( $ip, \@config )
Given an IP address, returns true if any of the items in
\@config matches that address, otherwise returns false.
Normally you use
check_device_only, passing the name of the configuration setting to load. This helper instead requires not the name of the setting, but its value.
There are several options for what
\@config can contain:
Hostname, IP address, IP prefix
IP address range, using a hyphen and no whitespace
Regular Expression in YAML format (no enforced anchors) which will match the device DNS name (using a fresh DNS lookup, so works on new discovery), e.g.:
- !!perl/regexp ^sep0.*$
"property:regex"- matched against a device property, such as
vendor(with enforced begin/end regex anchors)
To simply match all devices, use "
any" or IP Prefix "
0.0.0.0/0". Property 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.
