DNSAction.Spoof: spoof CNAME with higher TTL

[rishu007]

DNSAction.Spoof: spoof the response using the supplied IPv4 (A), IPv6 (AAAA) or string (CNAME) value. TTL will be 60 seconds.

As per the documenation the default TTL for spoof CNAME value is 60 i have a use case where i have to dynamically construct the cname is there any way that i can assign higher TTL number and respond the CNAME from dnsdist itself?

Not with DNSAction.Spoof, but have a look at SpoofCNAMEAction: https://www.dnsdist.org/reference/actions.html?highlight=ttl#SpoofCNAMEAction

but this works with static cnames but i have to generate in dynamically using Lua

i am capturing the packet and constucting a cname from it and want to return with higher TTL value

I don't think that's possible at the moment. You could open a feature request for adding the ability to set a TTL via DNSQuestion:spoof (DNSAction.Spoof is really limited and we will deprecate it at some point, likely in 2.1.0).
