bind and cname

Hi,

it's possible to configure a second level zone like this:

Quote:

for example, if I want:

host domain1.ext -> CNAME of www.domain2.ext ?

and NOT only www.domain1.ext -> CNAME of www.domain2.ext ?

Thankyou

Greetings!
If you want a CNAME that doesn't rely on a "www." prefix, then just set it up with
"domain1.ext domain2.ext".

You can configure your webserver (example: apache) to answer both "domain1.ext" and "www.domain1.ext" with a rewrite rule.

That way, with your CNAME, and a rewrite rule, you can resolve all four addresses;
www.domain1.ext
domain1.ext
www.domain2.ext
domain2.ext

This means that domain1.ext is a CNAME of www.domain2.ext (DON'T forget the trailing dot)
If you want to do this in a wildcard way use:

Code:

   IN CNAME www.domain2.ext.
* IN CNAME www.domain2.ext.

Thank you very much

Hi,
I can't use wildcard way. I still need ftp.domain1.ext, pop3.domain1.ext, mail.domain1.ext, etc.. pointing to a different IP.
There is no solution?

You didn't say that in your 1st post. Instead you said that you want everything pointing to www.domain2.ext, at least that it what I've understood:

Quote:

host domain1.ext -> CNAME of www.domain2.ext ?
and NOT only www.domain1.ext -> CNAME of www.domain2.ext ?

Anyway, you can use the DNAME RR to map *.domain1.ext to *.domain2.ext :

Code:

@ DNAME domain2.ext.

Assuming you already have a CNAME setup, here's what I would suggest;

1) You should have a PTR and an A record for "webserver.domain1.ext" (I'm sure your webserver has a real name)

2) Setup a CNAME for "www.domain2.ext" that points to "webserver.domain1.ext"

From there, you should be able to setup the Apache rewrite rule to redirect any "www.domain1.ext" to "domain1.ext".
You will also need to have a rewrite rule to strip the "www" from "www.domain2.ext".

It's been a long while since I've done this, so all of this is from memory.
