In the `dnsmasq.conf` file, add the line

    address=/.domain.tld/192.168.0.1

But use the IP you actually want as that end bit

While the accepted answer may have solved the author&#39;s problem, it is misleading as it suggests that the leading dot would match subdomains only, which is not true.

dnsmasq [ignores][1] any leading dots, so that

    address=/domain.tld/192.168.0.1

is equivalent to

    address=/.domain.tld/192.168.0.1

or even

    address=/......domain.tld/192.168.0.1

As of now (dnsmasq v2.76), there is unfortunately no way to specify some things (`server`, `address`, `ipset`) for

* a single domain name only, i.e. domain name without its subdomains
* only for the subdomains of a domain name

The only thing you can do, is to specify something for a domain name and all its subdomain and have override it for specific subdomains, e.g.

    address=/domain.tld/192.168.0.1
    address=/sub.domain.tld/10.10.0.1

This single domain name only case, may be tackled with different options, such as `host-record`, `srv-record`, which may be sufficient in some cases, but certainly not in all. It won&#39;t work for example, if you really need to use the `server` or `ipset` option for a single domain name only.

I am converting InputStream to JSONObject using following code. My question is, is there any simple way to convert InputStream to JSONObject. Without doing InputStream -&gt; BufferedReader -&gt; StringBuilder -&gt; loop -&gt; JSONObject.toString(). 

        InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
        BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, &quot;UTF-8&quot;));
        StringBuilder responseStrBuilder = new StringBuilder();

        String inputStr;
        while ((inputStr = streamReader.readLine()) != null)
            responseStrBuilder.append(inputStr);

        JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

I have a device that is already mapped to `domain.tld`. I now want to create a wildcard for all subdomains `*.domain.tld` so that they are mapped to the ip of `domain.tld`, too.
How do I do this with `dnsmasq`?

How do I configure a DNS service provider in such a way that requests to both `www.example.com` and `example.com` would show a website hosted on GitHub Pages? My browser&#39;s address bar should contain `example.com` when the website is opened.

My DNS service provider is `gandi.net`. It doesn&#39;t support the `ALIAS` DNS record type.

How do I set up GitHub Pages to redirect DNS requests from a subdomain (e.g. www) to the top-level domain (TLD, Apex record)?

I&#39;m having a problem building Docker images on my corporate network. I&#39;m just getting started with Docker, so I have the following Dockerfile for a hello-world type app: 

    # DOCKER-VERSION 0.3.4
    FROM    centos:6.4
    # Enable EPEL for Node.js
    RUN     rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
    # Install Node.js and npm
    RUN     yum install -y npm
    # Bundle app source
    ADD . /src
    # Install app dependencies
    RUN cd /src; npm install
    EXPOSE  8080
    CMD [&quot;node&quot;, &quot;/src/index.js&quot;]

This works fine when I build it on my laptop at home, on my own wireless network. It pulls down the requisite dependencies and builds the image correctly.

However, when I&#39;m on my corporate network at work, this same docker build fails when trying to pull down the RPM from download.fedoraproject.org, with this error message:

&gt; Step 2 : RUN     rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
 ---&gt; Running in e0c26afe9ed5
curl: (5) Couldn&#39;t resolve proxy &#39;some.proxy.address&#39;
error: skipping http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm - transfer failed

On my corporate network, I can access that URL just fine from my laptop. But once Docker is trying to build the container, all of a sudden it can&#39;t resolve at all. This behavior is the same for a variety of external resources (apt-get, etc.): They all can resolve just fine on my laptop on the corporate network, but Docker can&#39;t resolve them.

I don&#39;t have the network know-how to figure out what&#39;s going on here. Does anyone know why this strange behaviour would be occurring when building Docker containers?

I followed [this][1] tutorial for creating Signed SSL certificates on Windows for development purposes, and it worked great for one of my domains(I&#39;m using hosts file to simulate dns). Then I  figured that I have a lot of subdomains, and that would be a pain in the ass to create a certificate for each of them. So I tried creating a certificate using wildcard in `Common` field as suggested in some of the answers at serverfault. Like this:

    Common Name: *.myserver.net/CN=myserver.net

However, after importing this certificate into Trusted Root Certification Authority, I&#39;m getting `NET::ERR_CERT_COMMON_NAME_INVALID` error in Chrome, for main domain and all of its subodmains, for example: `https://sub1.myserver.net` and `https://myserver.net`.

&gt; This server could not prove that it is myserver.net; its security certificate
    is from *.myserver.net/CN=myserver.net. 

&gt; This may be caused by a misconfiguration or an attacker intercepting your connection.

Is there something wrong in Common Name field that is causing this error?

I have a website on a VPS.

The issue I am having is that when I enter the IP of the server, it links to the website.  
Even when entering mail.domain.com, it does the same thing.

How do I disable that, so a visitor would get a message or be directed to the domain?

I tried disabling the IP and mail a record on cloud flare but it didn&#39;t work.

My setup is:

    VPS on Linux Debian 
    Nginx
    no control panel just command line
    Cloudflare
    DNS setup with BIND


how to disable direct access to a web site by ip address

Is there a way I can reach my docker containers using names instead of ip addresses?

I&#39;ve heard of pipework and I&#39;ve seen some dns and hostname type options for docker, but I still am unable to piece everything together.

Thank you for your time.

I&#39;m not sure if this is helpful, but this is what I&#39;ve done so far:

- installed docker container host using docker-machine and the vmwarevsphere driver
- started up all the services with docker-compose
- I can reach all of the services from any other machine on the network using IP and port

I&#39;ve added a DNS alias entry to my private network DNS server and it matches the machine name that&#39;s used by docker-machine.  But the machine always picks up a different IP address when it boots and connects to the network.

I&#39;m just lost as to where to tackle this:

- network DNS server
- docker-machine hostname
- docker container hostname
- probably some combination of all of them

I&#39;m probably looking for something similar to this question:

https://stackoverflow.com/questions/27342382/how-can-let-docker-use-my-network-router-to-assign-dhcp-ip-to-containers-easily

Any general direction will be awesome...thanks again!

I bought a wildcard certificate for *.example.com. Now, I have to secure *.subdomain.example.com. Is it possible to create a sub-certificate for my wildcard-certificate? 

If it is, how I can do this?

SSL Multilevel Subdomain Wildcard

I am using postman to test an API I have, all is good when the request does not contain sub-domain, however when I add a sub-domain to URL I am getting this response.

&gt; Could not get any response
&gt; 
&gt; There was an error connecting to http://subdomain.localhost:port/api/
&gt; 
&gt; Why this might have happened:
&gt; 
&gt; The server couldn&#39;t send a response:Ensure that the backend is working
&gt; properly
&gt; 
&gt; Self-signed SSL certificates are being blocked:Fix this by turning off
&gt; &#39;SSL certificate verification&#39; in Settings &gt; General
&gt; 
&gt; Proxy configured incorrectly Ensure that proxy is configured correctly
&gt; in Settings &gt; Proxy
&gt; 
&gt; Request timeout:Change request timeout in Settings &gt; General

If I copy the same URL from postman and paste it into the browser I get a proper response, is there some kind of configurations I should do to make postman work with sub-domains?

I have mongodb with a `$text-Index` and elements like this:

    {
       foo: &quot;my super cool item&quot;
    }
    {
       foo: &quot;your not so cool item&quot;
    }

If i do search with 

    mycoll.find({ $text: { $search: &quot;super&quot;} })

i get the first item (correct).

But i also want to search with &quot;uper&quot; to get the fist item - but if i try:

    mycoll.find({ $text: { $search: &quot;uper&quot;} })

I dont get any results.

My Question:
If there is a way to use $text so its finds results with a part of the searching string? (e.g. like `&#39;%uper%&#39;` in `mysql`)

**Attention: I dont ask for a regex only search - i ask for a regex-search within a $text-search!**


mongoDB prefix wildcard: fulltext-search ($text) find part with search-string

I&#39;ve tried the following command but I am having trouble interpreting the results:

```bash
ls **
```

I&#39;m not sure exactly what it is outputting and why.

What do double-asterisk (**) wildcards mean?

Is there is a good way to add a new value to existing `Stream`? All I can imagine is something like this:

    public &lt;T&gt; Stream&lt;T&gt; addToStream(Stream&lt;T&gt; stream, T elem ) {
        List&lt;T&gt; result = stream.collect(Collectors.toList());
        result.add(elem);
        return result.stream();
    }

But I&#39;m looking for something more concise that I can use in lambda expression without verbosity.

Another question appeared when I tried to implement _PECS_ principle:

    public &lt;T&gt; Stream&lt;? super T&gt; addToStream(Stream&lt;? super T&gt; stream, T elem ) {
        List&lt;? super T&gt; result = stream.collect(Collectors.toList()); //error
        result.add(elem);
        return result.stream();
    }

Seems like wildcard doesn&#39;t work with `Stream.collect` and I&#39;m wondering why. Thanks in advance.

Adding new value to existing Stream

I would like to match strings with a wildcard (*), where the wildcard means &quot;any&quot;. For example:

    *X = string must end with X
    X* = string must start with X
    *X* = string must contain X

Also, some compound uses such as:

    *X*YZ* = string contains X and contains YZ
    X*YZ*P = string starts with X, contains YZ and ends with P.

Is there a simple algorithm to do this?  I&#39;m unsure about using regex (though it is a possibility).

To clarify, the users will type in the above to a filter box (as simple a filter as possible), I don&#39;t want them to have to write regular expressions themselves.  So something I can easily transform from the above notation would be good.
