Hello,

Almost every 4 hours when I receive my logcheck report I find entries like these:

Dec 15 07:26:05 ns named[1916]: client 201.16.18.3#4664: error sending response: host unreachable
Dec 15 07:26:05 ns named[1916]: client 201.16.18.3#4664: error sending response: host unreachable
Dec 15 07:26:05 ns named[1916]: client 201.16.18.3#4664: error sending response: host unreachable
Dec 15 07:26:44 ns last message repeated 5 times
Dec 15 07:26:44 ns last message repeated 5 times
Dec 15 07:26:44 ns last message repeated 5 times

What exactly does this mean? Is it an attack on my DNS server or someone trying to use it?

Thanks!

It's saying that someone is making a request to your server, but the reply can't get through to them. That happens sometimes due to firewall or network issues. If it's just one IP, or a few, but not everyone, then there's probably nothing you can do about it.
