            Email DNS Setup: How do I make HELO publish an SPF record? SPF_HELO_NONE - SPF: HELO does not publish an SPF Record
            Asked 2022-Apr-10 at 22:48

            My environment: hMailServer 5.6.8 on Windows Server 2022 Standard

            Let's say I have two domains (I don't really own these domains, they're just examples), www.myblog.com and www.mailserver.com. They are both hosted on the same machine and have the same IP address 1.2.3.4.

            The blog site www.myblog.com uses www.mailserver.com to send emails. The site www.mailserver.com only serves as a mail server; it is not accessible from a browser. I have set it up so that when www.myblog.com sends an email to someone, the recipient's email server receives SENT: EHLO www.mailserver.com, but sees SENT: MAIL FROM: message, so the recipient sees that the email came from myblog.com.

            Everything is working fine so far. Recently I decided to check the "spam rating" of my setup at https://www.mail-tester.com. I sent an email to the spam tester using the setup described above, and I saw a warning under the SpamAssassin section that says

            SPF_HELO_NONE        SPF: HELO does not publish an SPF Record

            My question is, how do I get rid of this warning? Are the DNS records as they should be? See below for the DNS records for each domain.

            The DNS records for each domain are as follows (note the PTR record for 1.2.3.4):

            My problem is that I can't seem to parse the NAME in the answer section. It seems to start with a pointer which makes no sense.

            I probably know at lot less about this than you but am wondering why you say that? firstByte is telling you there's a pointer and the following value (0x0c) shows you the offset of the name for compression purposes (if I've got that right). None of the other bits in the same byte as firstByte is set so that can be ignored from the point of view of the offset value

            I found the issue, in my case it was not DNS issue. The issue is related to the OOM(Out of memory) of the ec2 instance which is killing the process of a python script due to which the "Instance reachability check failed" and I was getting "Failed to establish a new connection: [Errno -3] Temporary failure in name resolution".

            After upgrading ec2 instance, the instance reachability didn't fail and able to run python script containing api.

            The instance status check failure indicates an issue with the reachability of the instance. This issue occurs due to operating system-level errors such as the following:

            GCE custom hostname reverse lookup in private DNS zones
            Asked 2022-Feb-01 at 09:38

            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.

            ANSWER

            Answered 2022-Feb-01 at 09:38

            After some serious digging I found a solution and tested it.

            Reverse DNS works even without a "regular" DNS records for your custom.hostname domain.

            To get reverse dns working lets assume your VM's in 10.128.0.0/24 network. Their IP's are 24,27,54,55 as in my example.

            I created a private dns zone and named it "my-reverse-dns-zone" - the name is just for information and can be anything.

            "DNS name" field however is very important. Since my network address starts with 10 I want all the instances that are created in that network segment to be subject to reverse dns. So the DNS name has to be 10.in-addr.arpa in this case. If you're using 192.168.... or 172.16.... then adjust everything accordingly.

            If you wanted just 10.128.0 then you can put 0.128.10.in-addr.arpa. Then you select the VPC networks zone has to be visible in and voila:

            Then you add the PTR records that will allow this to work. I'm setting all TTL's to 1 minute to shorten the wait :)

            After accepting wait a minute (literally) and test it:

            Why is ArgoCD confusing GitHub.com with my own public IP?
            Asked 2022-Jan-10 at 17:37

            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.

            C# BitConverter.GetBytes() padding is incorrect?
            Asked 2022-Jan-05 at 05:20

            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.

            As per the comments on the Question, the answer resides in Endianness.

            Network byte order sent from the dig command I am using to test with uses Big Endian order. However, my CPU architecture is Small Endian.

            Dotnet behind the scenes in their UDPClient class reverses the bytes if your system is Small Endian when sending bytes, and vice verse when receiving bytes. But because I was creating the bytes by hand using bit shifting in the Big Endian format, they were then reversed to be in Non-Network Byte order while everything else was in Network Byte order.

            The solution here is to either have conditional logic to test if your system is IsLittleEndian According to the Microsoft dotnet docs, or let the System.BitConverter class handle it for you.

            For instance: in my above example I was trying to convert a 32 bit int into a 16 bit unsigned bit. I ended up replacing the above code with:
