[Kea-users] Config line breaking / multiple vendor class identifiers

[perl-list]

This may be beyond the scope of what you were asking, but you can store some or all of the config in MySQL/MariaDB:  https://kb.isc.org/docs/using-the-kea-configuration-backend  which may make this particular aspect easier to manage.

> We’ve got a set of clients that all need the same Option-43 sent, but there’s no
> single vendor class identifier that can catch them all.
> In standard ISC server, we could do:
> if ((substring (option vendor-class-identifier, 0, 13) = "model-001.xyz"
> or substring (option vendor-class-identifier, 0, 15) = "mymodel-002.xyz”
> or substring (option vendor-class-identifier, 0, 12) = "model003.zzz"
> ))
> .. and define the options here

> In Kea it looks like I need to do:
> "client-classes": [
> # Client Class – Many Similar Models
> {
> "name": "ManyModels",
> "test": "(option[vendor-class-identifier].text == 'model-001.xyz') or
> (option[vendor-class-identifier].text == 'mymodel-002.xyz') or
> (option[vendor-class-identifier].text == 'model003.zyz')",
> .. define options here

> Is there a way to make this configuration more readable/editable? Having to put
> a dozen of these on one line will quickly become a wall of text. I tried
> escaping with \, breaking with a newline, and a few other things but it appears
> that the server wants the entire test in one line.

> I know I could create multiple client classes, one for each model, and just
> repeat the options I send, but that turns a horizontal wall of text into a
> vertical one.
