Hi,
I try to understand the NetmaskGroup feature.
https://dnsdist.org/reference/netmaskgroup.html?highlight=mask
:addMask(mask) works fine.
internal_NMG = newNMG()
internal_NMG:addMask(‘192.168.1.0/24’)
internal_NMG:addMask(‘192.168.2.0/24’)
addAction(NetmaskGroupRule(internal_NMG), NoneAction())
But I have difficulties to understand the correct use of :addMask(masks)
From the documentation:
masks (table) – Adds the keys of the table to the NetmaskGroup.
It should be a table whose keys are ComboAddress objects and values are
integers, as returned by exceed* functions.
Unfortunately I have no idea how to understand this sentence.
Does anyone have a working example?
You'd want to feed it the same data returned by one of these functions:
https://dnsdist.org/reference/config.html?highlight=exceedservfails#exceedServFails
or manually building a table as such (why?)
> table = {}
> table[newCA("127.0.0.1")] = 1
> foo:addMasks(table)
but I think the intended use case is just to pass the exceed* output into...
Thanks in advance!
Daniel
