This IP address is shared error

[ufo]

Hi everyone,
As a newbie in the Linux field I installed a server following Falko's manual "The Perfect Setup - Ubuntu 6.06 LTS Server ". It's on a separate machine, and the installation went pretty smooth. The problem occurs when I create a website with ISPConfig and I try to access it - I keep getting that "This IP address is shared..." screen. My server is behind a router and I have a private (192.168....) address, which I used creating the website in ISPConfig. My domain name is hosted at Yahoo and I played with the DNS settings there with no avail. My domain there is forwarded to the IP address of my router. Read everything posted here about this error and still have no idea what might be wrong. I'm positive that might be a DNS issue, but I don't know how to fix it. My server name is ubuntu.example.com and it has DNS, Postfix, everything. The website I created is www.example.com.
I'm fighting with it for couple of days already and I would appreciate any help.

Thanks!

What's the output of

ifconfig

, and what's in your Vhosts_ispconfig.conf file?

Hi Falko, thanks for the fast reply.
This is my vhosts_ispconfig file:

And this is the output of ifconfig:

Actually I managed to fix it late last night (Eastern time) by editing the A records in my Yahoo Control panel and pointing them to my router's IP address.

Thanks again, I really appreciate your efforts.

Hey UFO,

I have also been PLAGUED by this pesky IP SHARED error.

Being not a technical person at all, I really don't know what the heck you and Falko are talking about BUT I HAVE THE SOLUTION:

ISP Manager --> Sites --> YourDomain.com --> Co-Domains

click on the IP address to see in Co-Domains --> ISP Domains

and in there, in the ISP Domains section, GET RID OF THE WWW in the "Hostname", which is the first field there. LEAVE THE HOSTNAME FIELD EMPTY, and click save.

Go back to your domain, and you will see the IP SHARED problem is GONE.

Enjoy

[till]

1) The sahred IP page is not an error.
2) The solution you found is created by ISPConfig automatically, the error you did is that you set the domain limit too low and thats not the fault of ISPConfig.
3) You should know that www.domain.com and domain.com are not the same. If you would have entered www.domain.com, you would have seen the website. If you want to see the website too when you just enter domain.com in the webbrowser, you need this co-domain with empty host of course. Neither ISPConfig nor your internet browser can guess your intentions as domain.com might be a completely other site then www.domain.com.
