[Aspdns-users] Perseal url solution

[Tom <to...@im...>]

Hi Giuseppe,

I managed to build a solution after my original post which includes the idea
of a redirecting asp page.
I placed the asp script (found at the bottom of this post) in the default
file of the default website.

Because I didn't want to bind the host (user1 for expaple) to a specific
website ("poluting the IIS metabase").
I was forced to use the default website because I thought this was the
*only* site that intercpets hosts with no bindings.

I would also like to note that this worked only at the office and not from
an external location rendring te solution worthless. I suppose this is a
security setting with us at the office.

I think that you are suggesting the following:
Stop the default website and create a "general redirect purpose website"
which is the only one with no HHN bindings which takes appropriates action
for incoming requests depending on domain name and subdomain.

Some other questions if you have the patience (I'm a newbie to this)

- Statement : It is not possible to have a "website" wich intercpets all
request for a *specific* domain. A binding which ignores the sub domain in
effect.
for example : user1.webiste.com and xerezrser goes to webiste.com where
user1 or 'xerezrzer' is nowhere defined.
(the "general  redirect purpose website" is actualy nicer because it
centralises code!)

- Question about terminology :
	given abs.website.com :

	website.com is a domain
	abs.website.com is a subdomain as well as a Host Header Domain
	abs is a host header

	Is this correct ??


Thanks very much!

	Tom

Hi,
the solution is very simple. First you need to create hostname (or cname)
type records in your DNS. This can be easily done with ASPDNS, from a web
page directly by your visitors.

DNS maps only a computername with IP address, so user1.domain.com will map
your computer(s) IP(s), BUT when the request arrives to the web server (IIS
5 in the case), it will be only processed by the (virtual) web server who
has an appropriate or empty HOST HEADER NAME.

You can find the HHNs of a web server under the Web Site page clicking on
Advanced on the web site's Properties.

But remember:
1. there can be only one virtual server with an empty HHN;
2. leaving the Default web site running if the first source for hackers to
exploit your server - I absolutely recommend not to do so; also do not
delete it, or IIS will recreate a similar site the first time you attempt to
make a web site - just leave it stopped;
3. empty HHN has special meaning in IIS, it means "every host header name"
not specified elsewhere.

So you don't need ADSI to create confusion in you IIS metabase, but only a
single ASP pages who "reads" the HHS requested by the client, searches a
database (or text file, XML,...) and makes a redirect or some action.

Regarding your last question, ManageServer uses RPC and is able to manage a
computer's DNS using only a pure TCP connection between machines. But the
impersonated user from the controlling machine HAS to have an account on the
controlled server with privileges enough to change DNS records (at least DNS
admin rights).

Even if there are very few people on this list already, there are more than
3.000 downloads for ASDPN files only on Sourceforge, and I'm in touch with
guys who run ASPDNS in various production environments, including server
farms with multiple DNS controlled from one or more IISs.

Regards,
gsa
