Re: [dnsdist] Only see question events being logged via protobuf, no response ?

[scott McGillivray]

The issue i have is that one of the fields in dnsmessage.proto is called "class" which when compiled brakes the Ruby library i'm using since it interprets the field name as object of type Class and it blows up.

 

I have raised issue with repo to try work around.

This exact configuration works fine for me on master. How are you
testing exactly? Keep in mind that Response Actions are not executed on
a cache hit, you'll want to use addCacheHitResponseAction() for that.

The only places where you have access to a DNSProtoBufMessage object are
the alteration functions passed to RemoteLogAction() and
RemoteLogResponseAction():

function alterPB(dq, pb)
print(pb:toDebugString())
end

rl = newRemoteLogger('127.0.0.1:2222')
addAction(AllRule(), RemoteLogAction(rl, alterPB))
addResponseAction(AllRule(), RemoteLogResponseAction(rl, alterPB, true))
