Wildcard Dns
Jan 12, 2007
I bulk register .com names for future use, and out of all the ones I use, only about 30 have actual sites, whilst I have about 200 that are just not doing anything.
I have seen places like godaddy who whatever website people visit just gets fowarded to a landing page, and I have set it up so the nameservers all foward to my dns servers (I manage my own infrastructure).
I have seen through IIS it is possible to have a "catch all" website where any traffic goes there, however, how do I set this up in DNS?
I tried creating a zone called .com but that didnt work! and I really dont know what I should do!

I am starting to notice a range of IPs I'd rather not have access to any portion of my server's existence.
Can I add them to: /etc/apf/deny_hosts.rules
in this fashion:
12.34.567.
(This would effectively ban anyone whose IP began with these digits, regardless of what the last bracket's # is)
Possible?
I'd test, but my IP does not reset so frequently and I don't want to lock myself out of the server if it ends up working.

I run a free hosting service where users can sign up for a free blog.
With wildcard DNS and A entry, the users that sign up for a blog get the addy: theirblog.mydomain.com
This all works but there is no scalability. I have reached the limit of what my server can take.
If possible I would like to run multiple servers with just one domain.
So that when server 1 reaches its limit, it is possible to sign up new users that gets theirblog.mydomain.com (same domain) but now its physically stored on server 2.
Is this possible if you use wildcard DNS for the users subdomain sites?
I am quite new at this. I know there are ways to manage one domain on several servers, but is this possible too with this setup using wildcard dns and subdomains?

Quote:
tar -zcvf sqldata.$date.tgz *.sql
As it seems the server is taking that * as a character, not as a wildcard.
What would be the proper character for a wildcard symbol?

Does anyone know.. if you have a wildcard ssl cert for *.domain.com meaning you can use anything.domain.com can you also use anything.anything.domain.com (ie. unlimited subdomain levels) ?.

So setting up wildcard DNS was easy enough, but I am trying to actually have wildcard *.*.mydomain.com
Is there any way to accomplish that, not having to add an entry for each *.actualsubdomain.mydomain.com ?

I have a server: serverA.maindomain.com
and another serverB.maindomain.com
The DNS records for maindomain.com are on serverA
so the serverB A record is on serverA which is fine (i am aware it's a risk if serverA goes down).
If I'm setting a sub domain of serverB such as site1.serverB.maindomain.com I have to setup an A record on serverA for the subdomain and I don't want to have to do this every time.
Is there anyway I can setup a wildcard A record for subdomains such as:
*.serverB.maindomain.com

Now that I have relieved a lot of frustration I can talk about my issue. We have a cpanel server and are trying to install a wildcard ssl certificate on it. As you could tell from above its not working out so well.
The cert was ordered an installed as *.domain.com . It works great on https://domain.com and [url]
However, when I do [url]its an epic fail. Its a seperate cpanel account even with its own dedicated IP address. I look in the httpd.conf file and see the :80 entry however, I need to add a :443 entry in a way that cpanel/whm will not change it next time i add an account.
When I try to install the SSL certificate in WHM on jeff.domain.com it tells me the domain does not match. So I am asking how do I get this to work? I have searched for quite a while on the net and have not come across anything that works.

Googlebot is eating up about 30GB bandwidth per month.
I want to prevent him (and other robots) from spidering:
[url]
and all derivatives thereof (e.g. [url])
Is this possible with robots.txt? How would the code look?
Will this work?
User-agent: *
Disallow: /directory1/page1.php
or do I need to somehow specify a wildcard, e.g.
User-agent: *
Disallow: /directory1/page1.php?*

I have [virtually] unlimited number of subdomains on my site, and I need SSL support on them. So, I think wildcard SSL certificate will do the job.
Can you recommend an affordable wildcard SSL cert provider supported by all the major browsers (IE/Firefox/Opera/Safari)?

I am not that much of a dns/server expert, and I really need help setting up wildcard dns for domain names.
I have 1 parent domain zone file. Let's name this domain "parentdomain.com". Now this domain is set up with private nameservers of ns1.parentdomain.com and ns2.parentdomain.com and everything works fine.
What I want to do is now have the ability to put ns1.parentdomain.com and ns2.parentdomain.com into any other domain on the web and make it forward to this Parentdomain.com web root.
How do I do this WITHOUT adding a zone file for each of these individual child domains?
The thing is that I have a project where I don't know which domains will have nameservers set to ns1/ns2.parentdomain.com, but I want them all to forward to the appropriate directory.

got the VirtualHost entries for Appache, so each Domain points to a folder.
The (Windows-)DNS runs on the server, means i have to create a new DNS Reverse-Lookup and Folder for each Domain seperatly, but this workflow appears to be pretty stupid..
Now my question:
Anyone can tell me how to setup somwhat a "Wildcard / Catchall DNS", and also "Catchall VirtualHost", so each Domain is automatically pointed to the right folder? Any scripts needed for that?

I'm working on the idea of an email wrapping/branding service.
I'd like someone to be able to send an email to the service structuring the email address like this:[url]
The part in italics is the real destination and the part in bold is the address of my server.
I'll then parse the real destination out of the email, wrap it in some stuff and send it on.
From what I've read I need to set up a wildcard MX record. I've tried that but the emails just don't seem to get there.
I'd value your thoughts on how to deal with this problem and what questions I should be asking.

"Do you support wild card sub-domains?"
a web host has sent me the following:
"Wild card sub-domains will not work with our standard shared hosting accounts. although the DNS configuration is available to have any sub domain not listed direct to an IP address the actually hosting account will not recognize a wild card DNS entry unless you have manually added the specific name of the sub domain."
The only part I understood was the first line. Maybe it is my lack of hosting related knowledge or maybe because English is not my native language, the second sentence is very confusing to me.
What is tech rep trying to say?

I am setting wildcard nameservers that are meant to resolve any dpim pointed to them. I need for my domain parking service.
I was able to set wildcard A records with BIND, and this is good. However, some registrars seem to look for the SOA records, and it seems that BIND doesn't allow creating such records. Therefore, I need to switch to another DNS software, but I can;t find any that supports wildcard SOA records.

I am not a domain squatter (i.e. I don’t have thousand and thousand of domains). Though I do have a good amount of domains that I am not doing anything with because I register the domains to start new projects (that never get started, sigh)…
Anyways, is it possible to point the name servers of a mydomainexample.com to ns1.mymaindomain.com and ns2.mymaindomain.com and without actually parking it or creating a zone file / httpd.conf entry, have it redirect to my mainmaindomain.com?
(i.e. can I create a zone like *.* or virtual host *.* and have anything that isn’t in the config files all point to my maindomain.com)?
Hopefully, my post makes sense. If it is possible, please list a way on how to set it up as well.

I'm trying to create a symlink (ln -s) in SSH with the goal of having a php-file to be able to be reached from my wildcard subdomains "username.domain.com". The reason is because of XMLHttpRequest that resides in the php-file. When trying to access it from username.domain.com I only get an error, because of the cross-domain issue.
Anyway, I got the suggestion of creating a symlink on the file system, but I can't really get the symlink right... Where should I place it on the file system?
This is the path to the script;
Code:
/home/web2753/domains/domain.com/public_html/ajax/status.php
I tried creating the symlink in various places, like in the /domains/ directory;
Code:
ln -s /home/web2753/domains/domain.com/public_html/ajax/status.php
But I don't seem to get it right! If I have understood everything correctly, I'm supposed to create a symlink for status.php so the Subdomains can access it as if it was placed directly under the subdomains.
This is what my .JS file looks like (with the XMLhttprequest, this might not matter..?)
Code:
/home/web2753/domains/domain.com/public_html/javascript/edit.js
Code:
var cururl = 'htp domain com'; // this forum didn't like this url?
function createRequestObject() {
var req;
if (window.XMLHttpRequest) {
req = new XMLHttpRequest();
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert('Problem creating the XMLHttpRequest object');
}
return req;
}
function handleDivTag(divtag) {
var divtag;
return divtag;
}
var http = createRequestObject();
var divhandler = new handleDivTag(null);
function sendRequest(ua_id,show,series) {
http.open('get', cururl+'ajax/status.php?ua_id='+ua_id+'&show='+show+'&series='+series+'&dummy=' + new Date().getTime());
http.onreadystatechange = handleResponseTwo;
divhandler.divtag = ua_id;
http.send(null);
}
function handleResponseTwo() {
if (http.readyState == 4 && http.status == 200) {
var response = http.responseText;
if (response) {
document.getElementById('editinfo'+divhandler.divtag).innerHTML = response;
}
}
}
Everything works except of the cross-domain issue which I'm trying to overcome by creating a symlink.

I have a small webstore with a SSL encryption for securing the site. But the SSL certificate is setup for the www.somethingstupidurl.com, and not just somethingstupidurl.com. The www.somethingstupidurl.com is validating well, but I get the warning of a possible "bad" site on the somethingstupidurl.com (not validating).
And I know a wildcard SSL will fix this. But I was wodering about is if I can use multiple servers with with several dedicated IPs? I have several subdomains which I would like to secure, but bying SSLs for each will be more expsensive than a wildcard. These subdomains are also located on several servers that have their own dedicated IPs, and I would like to be sure a wildcard would be the right thing to go for.

I recently had a wildcard setup for my domain. But now my main domain isn't loading.
The wildcard is for things like
xxx.domain.com
but not domain.com isn't loading what it used to be it's loading the files that the wildcard load.
