Resolver.Query hangs in simple NAPTR query

anders9ustafsson commented 4 years ago

Describe the bug Ran the following code:

var builder = ResolverBuilder.Begin();
var resolver = builder.AddDnsServer("8.8.8.8").UseRecursion().SetRetries(3).SetTimeout(1000).EnableCache().Build();
var query = resolver.Query("dev.nwise.se", QuestionType.NAPTR, QuestionClass.IN);

When using online service to lookup NAPTR records, the query provides two answers. With Ubiety.Dns'Core 4.0.0, the query hangs.

Using version 2.4.0 of the library yields a successful query with two answers.

To Reproduce Steps to reproduce the behavior:

Run the above code e.g. in VS Code.
Wait indefinitely for code to complete

Expected behavior Code should complete in a short period, returning a query object with two answers.

Desktop (please complete the following information):

OS: .NET Core
Version 3.1.3

It is not just NAPTR records. Time to do some digging.

The default TransportType was changed to UDP and no method was provided to change it. Adding a method to change transport but also changing default back to TCP.

We are getting a response back from the server, however, the query is being refused according to the response code.

It should be resolved in version 4.1.0 when it arrives on NuGet. Still working on the UDP issues.

Thanks, I will check in again on 4.1.0.

It should be resolved in version 4.1.0 when it arrives on NuGet. Still working on the UDP issues.

@coder2000 Does the problem with UDP still remain, or have you been able to solve this?

coder2000 commented 4 years ago

@anders9ustafsson It is still an issue, I haven't really dug into it yet. If you want to take a crack at it feel free.
