I also miss the logging feature.

I also know, I could "tcpdump --foo --voodoo".
But I do not want read tcpdump's interpretation of a dns packet.
I like to see what unbound thinks about it.

I also dislike running tcpdump as a parser with root privileges.
Yes, I could capture as root and parse as nobody, but that's not comfortable!

The suggested logging may be switched on/off via unbound-control.
So the "fast path" is less involved.

I simply want sometimes know, what questions a specific system
asks. Without voodoo ...

Anyway, as a postmaster, I would throw away any mailer which could not tell me
who is sending/receiving mail. And I would not using tcpdump.

As a webmaster, I would not use a webserver unable to to usual logging.
And also nobody uses tcpdump.

Why I am advised to do so as dnsmaster ?
