Wildcards in a Windows hosts file

Question

I want to setup my local development machine so that any requests for *.local are redirected to localhost. The idea is that as I develop multiple sites, I can just add vhosts to Apache called site1.local, site2.local etc, and have them all resolve to localhost, while Apache serves a different site accordingly.

I am on Windows XP.

I tried adding

127.0.0.1       *.local

to my c:\windows\system32\drivers\etc\hosts file, also tried:

127.0.0.1       .local

Neither of which seem to work.

I know I can set them up on different port numbers, but that is a pain since it is hard to remember which port is which.

I don't want to have to setup a local DNS server or anything hard, any suggestions?

Answer 1

Acrylic DNS Proxy (free, open source) does the job. It creates a proxy DNS server (on your own computer) with its own hosts file. The hosts file accepts wildcards.

Download from the offical website

http://mayakron.altervista.org/support/browse.php?path=Acrylic&name=Home

Configuring Acrylic DNS Proxy

To configure Acrylic DNS Proxy, install it from the above link then go to:

1. Start
2. Programs
3. Acrylic DNS Proxy
4. Config
5. Edit Custom Hosts File (AcrylicHosts.txt)

Add the folowing lines on the end of the file:

127.0.0.1   *.localhost
127.0.0.1   *.local
127.0.0.1   *.lc

Restart the Acrylic DNS Proxy service:

1. Start
2. Programs
3. Acrilic DNS Proxy
4. Config
5. Restart Acrylic Service

You will also need to adjust your DNS setting in you network interface settings:

1. Start
2. Control Panel
3. Network and Internet
4. Network Connections
5. Local Area Connection Properties
6. TCP/IPv4

Set "Use the following DNS server address":

Preferred DNS Server: 127.0.0.1

If you then combine this answer with jeremyasnyder's answer (using VirtualDocumentRoot) you can then automatically setup domains/virtual hosts by simply creating a directory.

Answer 2

To answer your question, you cannot use wildcards in the hosts file under Windows.

However, if you want to only change the hosts file to make new sites work.... you can configure your Apache like this and you don't have to keep editing it's config:

http://postpostmodern.com/instructional/a-smarter-mamp/

Basically a quick summary based on my setup, add the following to your apache.conf file:

 LoadModule vhost_alias_module modules/mod_vhost_alias.so

 NameVirtualHost *:80

  <Directory "/xampp/sites">
      Options Indexes FollowSymLinks Includes ExecCGI
      AllowOverride All
      Order allow,deny
      Allow from all 
  </Directory>

  <VirtualHost *:80>
      VirtualDocumentRoot c:/xampp/sites/%-1/%-2+/
  </VirtualHost>

This allows me to add an entry like:

127.0.0.1       test.dev

and then make the directory, c:\xampp\sites\dev\test and place the necessary files in there and it just works.

The other option is to use <Directory> tags in apache.conf and reference the pages from http://localhost/project/.

Answer 3

I don't think that it is possible.

You anyway have to modify the apache virtualroot entries every time you add a new site and location, so it's not a big work to syncronise the new name to the Windows vhost file.

Update: please check the next answer and the comments on this answer. This answer is several years old and not correct anymore.

Answer 4

To add to the great suggestions already here, XIP.IO is a fantastic wildcard DNS server that's publicly available.

      myproject.127.0.0.1.xip.io  -- resolves to -->   127.0.0.1
  other.project.127.0.0.1.xip.io  -- resolves to -->   127.0.0.1
   other.machine.10.0.0.1.xip.io  -- resolves to -->   10.0.0.1

(The ability to specify non-loopback addresses is fantastic for testing sites on iOS devices where you cannot access a hosts file.)

If you combine this with some of the Apache configuration mentioned in other answers, you can potentially add VirtualHosts with zero setup.

Answer 5

Editing the hosts file is less of a pain when you run "ipconfig /flushdns" from the windows command prompt, instead of restarting your computer.

Answer 6

I found a posting about Using the Windows Hosts File that also says "No wildcards are allowed."

In the past, I have just added the additional entries to the hosts file, because (as previously said), it's not that much extra work when you already are editing the apache config file.

Answer 7

You could talk your network administrator into setting up a domain for you (say 'evilpuppetmaster.hell') and having the wildcard there so that everything (*.evilpuppetmaster.hell') resolves to your IP

Answer 8

We have this working using wildcard DNS in our local DNS server: add an A record something like *.local -> 127.0.0.1

I think that your network settings will need to have the chosen domain suffix in the domain suffix search list for machines on the network, so you might want to replace .local with your company's internal domain (e.g. .int) and then add a subdomain like .localhost.int to make it clear what it's for.

So *.localhost.int would resolve to 127.0.0.1 for everybody on the network, and config file settings for all developers would "just work" if endpoints hang off that subdomain e.g. site1.localhost.int, site2.localhost.int This is pretty much the scheme we have introduced.

dnsmasq also looks nice, but I have not tried it yet: http://ihaveabackup.net/2012/06/28/using-wildcards-in-the-hosts-file/

Answer 9

I'm using DNSChef to do that.

https://thesprawl.org/projects/dnschef/

You have to download the app, in Linux or Mac you need python to run it. Windows have their own exe.

You must create a ini file with your dns entries, for example

[A]
*.google.com=192.0.2.1
*.local=127.0.0.1
*.devServer1.com=192.0.2.3

Then you must launch the dns application with admin privileges

sudo python dnschef.py --file myfile.ini -q

or in windows

runas dnschef.exe --file myfile.ini -q

Finally you need to setup as your only DNS your local host environment (network, interface, dns or similar or in linux /etc/resolv.conf).

That's it

I made this simple tool to take the place of hosts. Regular expressions are supported. https://github.com/stackia/DNSAgent

A sample configuration:

[
    {
        "Pattern": "^.*$",
        "NameServer": "8.8.8.8"
    },
    {
        "Pattern": "^(.*\\.googlevideo\\.com)|((.*\\.)?(youtube|ytimg)\\.com)$",
        "Address": "203.66.168.119"
    },
    {
        "Pattern": "^.*\\.cn$",
        "NameServer": "114.114.114.114"
    },
    {
        "Pattern": "baidu.com$",
        "Address": "127.0.0.1"
    }
]

Answer 11

I have written a simple dns proxy in Python. It will read wildcard entries in /etc/hosts. See here: http://code.google.com/p/marlon-tools/source/browse/tools/dnsproxy/dnsproxy.py

I have tested in Linux & Mac OS X, but not yet in Windows.

Answer 12

You may try AngryHosts, which provided a way to support wildcard and regular expression. Actually, it's a hosts file enhancement and management software.
More features can be seen @ http://angryhosts.com/features/

Answer 13

@petah and Acrylic DNS Proxy is the best answer, and at the end he references the ability to do multi-site using an Apache which @jeremyasnyder describes a little further down...

... however, in our case we're testing a multi-tenant hosting system and so most domains we want to test go to the same virtualhost, while a couple others are directed elsewhere.

So in our case, you simply use regex wildcards in the ServerAlias directive, like so...

ServerAlias *.foo.local

Answer 14

Here is the total configuration for those trying to accomplish the goal (wildcards in dev environment ie, XAMPP -- this example assumes all sites pointing to same codebase)

hosts file (add an entry)

file: %SystemRoot%\system32\drivers\etc\hosts

127.0.0.1   example.local

httpd.conf configuration (enable vhosts)

file: \XAMPP\etc\httpd.conf

# Virtual hosts
Include etc\extra\httpd-vhosts.conf

httpd-vhosts.conf configuration

file: XAMPP\etc\extra\httpd-vhosts.conf

<VirtualHost *:80>
    ServerAdmin admin@example.local
    DocumentRoot "\path_to_XAMPP\htdocs"
    ServerName example.local
    ServerAlias *.example.local
#    SetEnv APP_ENVIRONMENT development
#    ErrorLog "logs\example.local-error_log"
#    CustomLog "logs\example.local-access_log" common
</VirtualHost>

restart apache

create pac file:

save as whatever.pac wherever you want to and then load the file in the browser's network>proxy>auto_configuration settings (reload if you alter this)

function FindProxyForURL(url, host) {
  if (shExpMatch(host, "*example.local")) {
    return "PROXY example.local";
  }
  return "DIRECT";
}

Answer 15

You can use echoipdns for this (https://github.com/zapty/echoipdns).

By running echoipdns local all requests for .local subdomains are redirected to 127.0.0.1, so any domain with xyz.local etc will resolve to 127.0.0.1. You can use any other suffix also just replace local with name you want.

Echoipdns is even more powerful, when you want to use your url from other machines in network you can still use it with zero configuration.

For e.g. If your machine ip address is 192.168.1.100 you could now use a domain name xyz.192-168-1-100.local which will always resolve to 192.168.1.100. This magic is done by the echoipdns by looking at the ip address in the second part of the domain name and returning the same ip address on DNS query. You will have to run the echoipdns on the machine from which you want to access the remote system.

echoipdns also can be setup as a standalone DNS proxy, so by just point to this DNS, you can now use all the above benefits without running a special command every time, and you can even use it from mobile devices.

So essentially this simplifies the wildcard domain based DNS development for local as well as team environment.

echoipdns works on Mac, Linux and Windows.

NOTE: I am author for echoipdns.

Answer 16

While you can't add a wildcard like that, you could add the full list of sites that you need, at least for testing, that works well enough for me, in your hosts file, you just add:

127.0.0.1 site1.local
127.0.0.1 site2.local
127.0.0.1 site3.local
...

Answer 17

I could not find a prohibition in writing, but by convention, the Windows hosts file closely follows the UNIX hosts file, and you cannot put wildcard hostname references into that file.

If you read the man page, it says:

DESCRIPTION
     The hosts file contains information regarding the known hosts on the net-
     work.  For each host a single line should be present with the following
     information:

           Internet address
           Official host name
           Aliases

Although it does say,

     Host names may contain any printable character other than a field delim-
     iter, newline, or comment character.

that is not true from a practical level.

Basically, the code that looks at the /etc/hosts file does not support a wildcard entry.

The workaround is to create all the entries in advance, maybe use a script to put a couple hundred entries at once.

Configuration for nginx config auto subdomain with Acrylic DNS Proxy

auto.conf file for your nginx sites folder

server {
    listen 80;
    server_name ~^(?<branch>.*)\.example\.com;
    root /var/www/html/$branch/public;  

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_log  /var/log/nginx/$branch.error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
       try_files $uri /index.php =404;

}

Add to Acrylic hosts file 127.0.0.1 example.com *.example.com and restart Acrylic service. $branch - your subdomain name.

Set instead of root /var/www/html/$branch/public; your project path

Answer 19

This can be done using Pi-Hole, just edit the "/etc/hosts" and restart dns service.

nano /etc/hosts
pihole restartdns

Example:

127.0.1.1       raspberrypi
192.168.1.1     w1.dev.net
192.168.1.2     w2.dev.net
192.168.1.3     w3.dev.net

Answer 20

You can use a dynamic DNS client such as http://www.no-ip.com. Then, with an external DNS server CNAME *.mydomain.com to mydomain.no-ip.com.
