## reverse proxy – How to resolve single word domains to different IP:port combinations on local network?

I want to set up a local DNS server on my home network (like Pi-Hole or AdGuard) but add my own entries such that typing just `home` directs to my home assistant instance, `plex` directs to my plex instance, etc.

The problem I am foreseeing is that DNS can only resolve a name to an IP address, not IP:Port combo; and a bunch of my services run from the same machine (same IP). So when I type `home` it will go to `192.168.1.100` which is the right IP but I need to give nginx the right context to know which port to reverse-proxy to. Right now nginx is configured to redirect `home.mydomain.com` to the right port (and likewise for `plex.mydomain.com`, etc)

How do I configure the nginx reverse proxy to match on single word domains? Do i have to add an entirely different entry or can I do something to match on (`home.mydomain.com` OR `home`) in my nginx config?

Alternatively, do DNS have to resolve to an IP address? Or can i somehow configure pi-hole/AdGuard to resolve `home` to `home.mydomain.com`, which is then hairpinned back to my own network and routed by the reverse proxy?

I asked this question on (reddit)https://www.reddit.com/r/homelab/comments/jf0ant/local_dns_server_with_nginx_reverse_proxy_how_to/) and was told to use Caddy and SRV Records, but I am extremely confused how that helps me resolve single word DNS calls like `home` to the right IP + port.

This is (possibly) complicated by the fact that I want to do this for many words that resolve to the same IP but different ports. i.e., `plex` should be `192.168.1.100:plexPort`, etc.

## vps – Path of all domain’s emails accounts in shared hosting websites

My all Five(5) domains previously runs on a Shared Hosting Account using cPanel along-with a Primary Domain and other Four(4) domains as Secondary Domains on it.
This Shared Account used for Web Server, DNS Server as well Mail Server too.
I have recently migrated my hosting account from Shared to another VPS server and I have converted a secondary domain (example.com) into full website i.e. now it’s not a child domain.
Now my secondary domain example.com becomes Primary Domain on that VPS using CyberPanel but my email accounts associated with the domain example.com can’t shows under ListEmail Accounts in my CyberPanel Hosting Control Panel.
So, I need to find out all email accounts associated with example.com and manually transfer all that within it (example.com).
Now how can I find the correct emails directory of all domains; Is all emails are in a single directory or in different dir’s.
I need to extract all emails account of a particular secondary domain like example.com.

## web – How to securely transfer cookies between two domains?

Let’s say you have a website https://example.org which is being decommissioned and redirected to https://example.net.

Your users have a cookie on https://example.org which contains some authentication token for the backend services (e.g. https://backend.example.org). You want the redirect on https://example.org to also transfer this token to a cookie on https://example.net.

Without asking the user to reauthenticate, what is the best way to securely transfer this?

## domains – HubSpot CMS site is not secure unless someone types in “www.”

so we connected our domain with HubSpot CMS. They only support SSL for subdomains, so when someone does not type in “www.” they are prompted with a security warning. They told me I needed to set up a redirect through GoDaddy for it to always go to the root domain (`https://example.com`)?

In GoDaddy’s forwarding section I see one that says “Domain” and the other says “Subdomain”.

What do I type in each of these boxes so that my site goes to `https://example.com` no matter what someone types in?

## reference request – Well-posedness of hyperbolic system with constant coefficients in finite domains

I’m studying the PDE
$$frac{partial u}{partial t} + A_xfrac{partial u}{partial x} + A_yfrac{partial u}{partial y} + A_zfrac{partial u}{partial z} = 0$$
with $$A_x, A_y, A_z$$ being constant matrices, that arise either from the acoustic or linear elasticity system. The equation is solved in some complicated 2- or 3D domain (for example, with cavities or sharp edges), with boundary conditions of the type $$Bu = f$$. These boundary conditions may represent the condition of given normal stress on the boundary for the linear elasticity or given normal velocity on the boundary for acoustics.

I would like to know, how to check if the problem is well-posed. In particular, I need to know

• The properties of the domain, i.e. if it is simpy connected, or if the boundary is piecewise smooth, etc. The papers considering the well-posedness for this system that I’ve found so far consider $$u(t)$$ to be defined either on the set with $$C^infty$$ boundary (for example, this one). Maybe there is a generalisation to the case of piecewise smooth boundary?
• The number of boundary conditions or rank of B matrices. My intuition tells me that this sholud depend on the postiton of the characteristic surfaces on the boundary, but I haven’t found any useful information yet.

## domains – possibly wrongly configured nameserver from the hoster

my domain is managed by my web host.

Now I have changed my web host and am using the same provider as the domain.

So that I can set up the web space before the move, the hoster has set up a subdomain (mycompany.hosterdomain.com)

the webhoster has now updated the nameserver entries for the domain, but when i access my domain i am always forwarded to mycompany.hosterdomain.com.

In my opinion, there is an error in the name server administration, since the host name is not correctly resolved here.

the hoster says, however, that I have to change the url in my wordpress admin dashboard.

can someone tell me what went wrong here?

I have already moved websites several times, and normally only the nameserver entries have to be changed for the domain so that the domain refers to a new webspace. or am i wrong?

edit:
I played around a bit and I noticed that my domain was redirected to 301 mycompany.hosterdomain.com. the hoster has probably not changed any nameserver entries in the domain.

## seo – How to handle sitemaps in regards to forwarded domains?

I’m trying to make my website as SEO friendly as possible, but I’m confused how to handle forwarded domain sitemaps. Are they even necessary?

Ex:

I have a site called `mywebsite.com`, which has pages:

I also have a domain `coolProduct.app` that points to `mywebsite.com/coolProduct`.

I want to make my `coolProduct.app` domain more SEO friendly, and thus am curious about generating a sitemap for it. However, I can’t generate a sitemap for the domain as I suspect the actual pages are a part of a different domain (`mywebsite.com`).

Is this an issue? Or does it not matter in terms of SEO, and I should just make sure mywebsite.com has a sitemap registered with the google console (and listed in the `robots.txt` file)?

Thanks in advance for any help!
