proxflix | yet another smart DNS solution to bypass geo | DNS library

I'm trying to parse a DNS response using java. I'm following RFC-1035 for guidelines on how to send requests and receieve responses, the format that is.

According to said RFC the answer section of a response should look like so:

I have a k8 setup that looks like this

ingress -> headless service (k8 service with clusterIp: none) -> statefulsets ( 2pods)

Fqdn looks like this:

I am trying to create a custom DNS server for my domain on an AWS EC2 Instance. The instance is running Ubuntu 20.04 LTS and the DNS server is configured using bind 9. When I restart the bind server using

sudo service bind9 restart

The /var/log/syslog shows a successful start with no errors.

Now if I run a dig on the server itself like:

I'm looking to find a way to use a custom DNS resolver for a nodejs request using node-fetch. I think there is a star of explaining here : Node override request IP resolution but I can't manage to make it work for any request. My goal is to use an alternative DNS resolver, such as cloudflare (1.1.1.1) or Google public DNS (8.8.8.8) instead the OS / ISP default DNS resolution.

I am requesting an API using the python requests library:

My python script is run once a day by the scheduler, Once the python script gets run, I am getting this error and the PID of the python script is getting killed showing OOM. I am not getting whether it's a DNS issue or an OOM (Out of memory) issue as the process is getting killed.

Previously script was running fine.

Any clues/help will be highly appreciable.

I want to create an instance in Google Cloud Engine with a custom (private) hostname. For that reason, when creating the instance from the Console (or from an SDK) I supply the hostname, or example instance0.custom.hostname.

The instance is created and the search domain is set correctly in /etc/resolv.conf For Ubuntu in particular I have to set the hostname with hostnamectl but it is irrelevant to the question.

Forward DNS lookups work as normal for instance0.custom.hostname. The problem comes when I do a reverse lookup for the private IP address of the instace. In that case the answer I get is the GCE "long" name instead of my custom hostname.

How can I make the reverse lookup reply with my custom name instead of the GCE?

I know in Azure you can use a Private DNS Zone with VM auto-registration to handle the "custom hostnames". I tried using a private zone with Google Cloud DNS (PTR records) but with no luck.

I have just set up a kubernetes cluster on bare metal using kubeadm, Flannel and MetalLB. Next step for me is to install ArgoCD.

I installed the ArgoCD yaml from the "Getting Started" page and logged in.

When adding my Git repositories ArgoCD gives me very weird error messages: The error message seems to suggest that ArgoCD for some reason is resolving github.com to my public IP address (I am not exposing SSH, therefore connection refused).

I can not find any reason why it would do this. When using https:// instead of SSH I get the same result, but on port 443.

I have put a dummy pod in the same namespace as ArgoCD and made some DNS queries. These queries resolved correctly.

What makes ArgoCD think that github.com resolves to my public IP address?

EDIT:

I have also checked for network policies in the argocd namespace and found no policy that was restricting egress.

I have had this working on clusters in the same network previously and have not changed my router firewall since then.

I purchased a custom domain name, I want now to modify my Github pages website which was accessible with : https://jeromevdev.github.io/santaclaus_nft/ to be accessible with https://santaclaus-nft.com.

What I did :

1. Added a file CNAME to my repository which contains santaclaus-nft.com
2. Added a redirection on my hosting provider to redirect https://santaclaus-nft.com to https://jeromevdev.github.io/santaclaus_nft/
3. In my project settings under pages I added custom domain and I setted it to : and here is the problem happening.

What am I missing ?

I am working on writing my own DNS server in .net core. I'm at the stage where I am encoding the response payload to send back, and the schema shows that most of the numbers are encoded as 16 bit numbers. C#'s ints are 32 bit numbers. Not a big deal, I'm just dropping off the remaining 16 bits from the front of the number I have no problem with that.

I was doing this by hand until I discovered the System.BitConverter class. I tried using it, however, and the results I came up with were reversed of what it came up with.

For example:
