Deadwood update
Original posting

I have updated Deadwood and discuss DNS-over-TCP.

Deadwood update

I have fixed some warnings that came up when compiling Deadwood using llvm's clang.

It can be downloaded here:

DNS over TCP

Since this has come up twice this last week: DNS-over-TCP is optional as per section 6.1.3.2 of RFC1123. Any program or web service that considers no DNS-over-TCP an error is not RFC-compliant.

Not having DNS-over-TCP is more secure, because it gives attackers a smaller surface to attack. While I do allow MaraDNS users to have DNS-over-TCP via the zoneserver program (Windows users will just have to modify and compile the source, or use Cygwin if they want zoneserver), it is not necessary or even that good of an idea.

RE: Deadwood update
Now works OK on FreeBSD, no High CPU usege, stable work.
Average CPU usage on heavy load test DNS server is near 1% of 3.5GHz core i7

But on WinXP Deadwood still freezes windows after ~2 weeks of productive usage.
I think that problem is in windows libs (90% / 10%), but not in Deadwood.
