networking – What DNS records are required to configure web hosting for a subdomain?

I’ve browsed several questions about DNS setup for subdomains and not quite found an answer, so I’m hoping you can assist.

Our domain name ( is registered with one provider (NetRegistry), and our main web site is now hosted by SquareSpace (configured using a CNAME record). We need to set up a separate, simple web hosting service with another provider using a subdomain (

I was originally advised that we could use their nameservers, and so created NS records for the subdomain with our registrar using the zone management tool available through their control panel. This didn’t work, though. Speaking to the hosting provider, I was advised to add an A name record for the subdomain pointing to a specific IP address for the new site, which I’ve also done. But throughout this process the subdomain has not resolved; I get a failure when using nslookup, as though it’s not recognised anywhere.

Currently we have both the A and NS records for the subdomain on our registrar, and I suspect we should only have one or the other; is that the case? I’m rusty with DNS and didn’t think this would be complicated, but if anyone can advise what records should be sufficient to for setting this up, I’d appreciate it.

How can I configure Google voice access so that I only have to say “hey Google” once?

After I say “hey Google”, Google voice access is letting me say a few voice commands. However, after a few ones, I have to say “hey Google” again to be allowed to give further voice commands.

How can I configure Google voice access so that I only have to say “hey Google” once?

I did disable “time out after the speech”:

ipfilter – configure rras ip filter windows server 2019

Tell me please how I can configure the access list using the RRAS inbound / outbound filter for subnets in the screenshot. Deployed Win server with two subnets and Internet access using RRAS NAT. 2 machines are connected to the server in different subnets. How to make sure that traffic from network 2.0 can go to network 1.0, but on the contrary, not. Tried to create a rule, but in this case, routing between networks is broken in both directions link to screenshot – direct link to screenshot

Configure the default route that the Azure VPN Gateway provides to P2S clients (to allow for multiple connections)

I have two completely independent Azure environments that I control. One virtual network uses the address space, the other uses the address space. I need my users to be able to connect to both vnets simultaneously via point-to-site (P2S) VPN connections.

I have much of this working. I’m using plain-old, built-in rasphone for this- no special extra VPN client software, I set up the connection directly in rasphone with no downloads or installs. Either one of the connections work perfectly alone, the problem comes when I try to use them together.

Apparently, when I connect to either of them, a route gets added for So when I connect to both of them, two conflicting routes get added. The one with precedence wins, so in practice one connection of the two will work, while the other fails. In case that isn’t clear, here’s the output from route print:

Network Destination        Netmask          Gateway       Interface  Metric     36     36

In the above case a tracert for shows that it’s trying to resolve the IP address via the gateway (the one with precedence), which is the wrong one, so it finds nothing. I need to route traffic through, and through

Now, I could try to modify the route explicitly on every client PC, but that adds a whole extra step to the process of setting up each and every PC. The Azure VPN Gateway is obviously capable of telling the client what routes to add, since the route gets added automatically every time I connect, so I’m hoping there’s a way to configure that default route and limit it to only the IP range I want. And if there isn’t a way to explicitly alter it, is there at least some way I can rearrange my address spaces so that the gateway realizes I don’t want to route all of

networking – How to configure my router to redirect clients to use AdGuardHome as DNS?

I have setup a local server in my LAN to host a AdGuardHome DNS server that filters Ads etc (a bit like PieHole if you want) on a fixed, e.g. IP

If I configure that DNS server to be used in a client (e.g. Windows 10) instead of “Automatic”, I can see that machine connecting to the DNS server and the filter works fine. The manual setting allows me to set specific filters for that client (e.g. parental controls) that do not apply to others. All other machines use my router (LinkSYS Velop) as DNS on which redirects to whatever my provider has set.

What I would like to achieve is that all clients connect to the DNS at .1.88 instead of the default at 1.1 and that I can see and configure all my clients on the AdGuardHome interface:

I thought I can achieve that by setting the DNS in my router to the .1.88 address:

enter image description here

But all that I get then is that I can now see my router in the AdGuardHome dashboard doing all the requests and there is no way to configure the filters by device:

enter image description here

Should it not be that the router is telling the clients that they should be using 1.88 as a DNS server instead of the router using that address? Or is there another setting I need to apply to have this achieved?


java – Backend service to configure and interact with custom Android app remotely?

I am developing a custom Android application in Java to run on a phone (the target phone). The app controls and collects data from a BLE wearable device connected to the target phone. Ideally, the app running on the target phone can be configured and setup remotely from some backend service/app.

An example scenario: I need the BLE device to perform an action and collect data at a specific time. Currently, I can set this up using the app on my target phone directly by selecting which time of day I want to start the task and then “configure” these commands to the connected device. What I want is for the target phone connected to the BLE device to instead be a middleman between a remote service and the BLE device. I don’t need full access or screen-sharing of the target phone, I just need to be able to send certain functions and configure settings that the phone can then in turn configure with the connected device.

What sort of service/backend will I need in order to connect to the target phone from a remote location?

snakemake – configure rules to run with local container (Singularity, Docker)

For snakemakev5.27+

Is there a way to run snakemake with the container directive that points to a local image? E.g. if I store the Docker containers on Dockerhub, and I also have a copy locally, when running snakemake, I don’t want the rule to pull a singularity image copy from DockerHub if there already exists the exact copy locally. Makes for faster runs.

apache2 – Configure Apache to associate subdirectory/subdomain to Flask port

I am running Flask on a server that has Apache installed. Users are accustomed to accessing websites on the server using subdirectories such as

My question is, can I make Apache show when is accessed whilst showing in the address bar? Up to now I have managed to create a redirection using an .htaccess file in but the address bar changes to which I would like to avoid.

I would be happy to use subdomains instead of subdirectories if it makes a difference (
