make wildcard subdomains on localhost work

edman007 · 09-03-2005, 01:10 AM

is there anyway to make wildcards work for subdomains on localhost (or any other thing, i just want it to point to me), what i mean is is make anything.localhost go to 127.0.0.1 but not have to put anything.localhost into any specific file, i want to just put *.localhost into a file so that anything.localhost, something.localhost, blah.localhost all point to 127.0.0.1, i have tried putting *.localhost in my /etc/hosts file but it didn't work, and the only thing i found so far is setting up bind but i feel that would be overkill

so is there any way to do this without setting up bind?

BIND is needed. Just open localhost system and add
*.localhost IN A 127.0.0.1

and restart bind.

ok, well now the reason i didn't want to use BIND, i cant figure out the config files

, i need help setting it up

i also tried adding "nameserver 127.0.0.1" (at the top) to my /etc/resolv.conf but that didnt seem to help

my /etc/named.conf is

Code:

options {
        directory "/var/named";
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
        // query-source address * port 53;
};

//
// a caching only nameserver config
//
zone "." IN {
        type hint;
        file "caching-example/named.ca";
};

zone "localhost" IN {
        type master;
        file "caching-example/localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "caching-example/named.local";
        allow-update { none; };
};

my /var/named/caching-example/localhost.zone (i thought it went at the end of this file) is

Code:

$TTL    86400
$ORIGIN localhost.
@                       1D IN SOA       @ root (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum

                        1D IN NS        @
                        1D IN A         127.0.0.1

add line:

*.localhost IN A 127.0.0.1

To file /var/named/caching-example/localhost.zone

And restart bind and test it with nslookup/dig

You can also use Webmin to manage bind. It is a simple web based management tool that can be used to do a lot of configuration on a *nix system. Its beauty is that it is exactly the same to perform any task on any flavor of *nix.

You can manage your DNS, play with a Samba config, manage a MySQL database, and much much more!

There is a Java shell environment you can get to from webmin. There is also an interesting file browser available.

One thing I liked was making changes with Webmin and then checking the config file itself to see what changes it made. This was the way I learned to manage my DNS entries. Now I do it all from the command line.

Note, you need a trailing . after localhost:

*.localhost. IN A 127.0.0.1

Hope this helps!
