Server configuration

[z0ccc]

Hi, Did you have to do any server configuration for this project? Also what domain records do you use? Thanks!

First, your server needs a public IP. Then configure your DNS, add NS type records, and add A type records.

Host	Type	Value
dns-leak	NS	ns1.dns-leak.writebug.win
ns1.dns-leak	A	35.189.162.161(public IP)

Finally, modify the program source code and modify SERVER_PUBLIC_IP to your public network IP.

Hi, Thanks for the response! Ive setup my domain records like this:

My server is running Ubuntu 22.04 x64.

I cloned this repo on my server and set SERVER_PUBLIC_IP in dns_server.py to my servers public ip (45.77.221.213).

I then ran run_daemon.sh and it succesfully created the output file with no errors.

But when I try to run curl e027c8af-2a4d-44f1-8891-ff6296451596.dns-leak.locatejs.com:8053 It gives me the error curl: (6) Could not resolve host: e027c8af-2a4d-44f1-8891-ff6296451596.dns-leak.locatejs.com

Do you know what could be going wrong? Thanks

You can use the dig command to test. example: dig github.com # A record dig ns1.dns-leak.locatejs.com @45.77.221.213

In your case, the dig ns1.dns-leak.locatejs.com request is timing out.

It is not necessary to have ns1 as a subdomain of dns-leak.locatejs.com. You can try the configuration below.

Host	Type	Value
dns-leak	NS	leakns1.locatejs.com
leakns1	A	45.77.221.213

In addition, instead of using run_daemon.sh, use python3 dns_server.py to directly output error messages

I have changed the configuration to:

When I run dig dns-leak.locatejs.com @45.77.221.213 I get the output:

Running python3 dns_server.py returns no errors.

But when I run curl db917ea0-e612-11ec-8fea-0242ac120002.dns-leak.locatejs.com:8053 I get the error curl: (6) Could not resolve host: db917ea0-e612-11ec-8fea-0242ac120002.dns-leak.locatejs.com

Do you have any advice on how I can fix this? I appreciate your responses. Thanks

Please run the commands, dig @8.8.8.8 dns-leak.locatejs.com ns and dig @8.8.8.8 leakns1.locatejs.com . What is the output of the above command?
