WIld card DNS used to work, no more

[bluepolo]

Apologies in advance for the possible noob question

For sometime I’ve used wildcard DNS, basically making the server * in DNS manager. Now though it doesn’t work anymore. I get the following in the log:

30-Apr-2007 22:37:47.374 dns_rdata_fromtext: sub.domain.com.zone:2: near ‘*.sub.domain.com.’: bad name (check-names).

I don’t kno exactly when this happened, because this particular requirement was not in use for a month or 2.

Any ideas?

TIA

well I found a way to do it.

In the A record have a machine of say any.domain.com. Then add an alias ie cname of *.

Works fine

I try that and it did not work. It root domain points to the dns server only.

Hi, I just tried it and it worked fine.

1 – create a zone – I called my zone ‘domain.com’

2 – in the nameserver field I put ‘ns’

3 – click onto ‘machines’

4 – doubleclick the entry you find

5 – click on the + sign next to aliases

6 – type ‘*’

7 – click OK and save etc

When I do nslookup:

madmax:~ bp$ nslookup ns.domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53
Name: ns.domain.com
Address: 192.168.12.1

and

madmax:~ bp$ nslookup any.domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53
any.domain.com canonical name = ns.domain.com.
Name: ns.domain.com
Address: 192.168.12.1

and

madmax:~ bp$ nslookup fred.domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53

fred.domain.com canonical name = ns.domain.com.
Name: ns.domain.com
Address: 192.168.12.1

I’m on 10.4.10 right now, and its worked since whenever I made my last post.

Cheers

I must correct myself. I am able to get wild cards working, only if I us the DNS server for the wildcard entry. however if use a wild card on any other server (machine) this does not work.

I did it ll over made the host a diferent IP, and it still works:

madmax:~ bp$ nslookup ns.domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53

Name: ns.domain.com
Address: 192.168.12.2

and

madmax:~ bp$ nslookup fred.domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53

fred.domain.com canonical name = ns.domain.com.
Name: ns.domain.com
Address: 192.168.12.2

Sorry if I am not understanding correctly!

This works fines using the fred sub domain.

toddjob:~ todd$ nslookup fred.exampleco.com
Server: 10.32.32.32
Address: 10.32.32.32#53

fred.exampleco.com canonical name = ns.exampleco.com.
Name: httpserver-02.exampleco.com
Address: 10.32.32.9

However, when no sub domain is entered this is the results we have:

toddjob:~ todd$ nslookup exampleco.com
Server: 10.32.32.32
Address: 10.32.32.32#53

Name: exampleco.com
Address: 10.32.32.32

Any ideas?

*domains and ips have been changed per our security policies.

How did you create your zone?

Leaving off the sub domain it still works for me

madmax:~ bp$ nslookup domain.com
Server: 192.168.12.1
Address: 192.168.12.1#53

Name: domain.com
Address: 192.168.12.2

If you do exactly what I did, do you get your result or mine?
