DNS lookup fails using consul on windows box (from demo)

[Mark Risen]

This is probably something dumb I missed but I can't figure it out.

I'm going through the getting started pages and am at the part when I'm trying to query the service through the DNS API and it's not working.

Running a console in admin mode, I started a consul server with consul agent -dev -config-dir Configuration

The consul server starts up and finds the Web service. I can also see the DNS port is 8600

In a second consul in admin mode, I start nslookup, changed the server with server 127.0.0.1 and set the port with set port=8600.

I can see the server changed to 127.0.0.1 and I can see the port changed with the set all command

Then, I attempt a query with Web.service.consul but always get back *** localhost can't find service.Web.consul: No response from server.

I've looked at my firewall settings and I can see consul set there. I'm not sure what to look for at this point.

I've also tried telnet . 8600 but could not open a connection on that port, though I'm not sure if that would actually work.

Any ideas on what I am missing?

Ok, first, using a . instead of an IP address does not work for telnet. When I tried telnet 127.0.0.1 8600 I did get a connection.

Next, I kept seeing dig being referenced so decided to download that tool and try it. Sure enough it works. I don't know why nslookup doesn't work though. Regardless, all is good.

Cheers!

hello, 

Have a look here:

https://github.com/hashicorp/consul/issues/569

They suggest couple of ways to change consul to use port 53 (the expected port)

please not that this is fine for dev, however is better put a dns server on front of consul for production.

Thanks

alvaro.
