DNS configuration on Linux

[Mauro]

The scalix-wizard check the DNS and i receive this error message:
"The DNS name service does not appear to be configured."

I have a Linux server behind the firewall (DMZ) and we don't have a DNS-Server. The DNS-Server is on the ISP and the firwall make PAT from the WAN-IP to the LAN-IP ( DMZ:10.0.0.20)!

What I have to configure, so that the check will be positive?

Thanks
Mauro

PS: On the DNS-Server i have configure the alias for "scalix-default-mail" and the Reverse DNS Lookup is working!

The wizard does a simple nslookup for the server's host name.

If that is not found, the error is reported.

You will need to ensure that:

1) /etc/resolv.conf is pointing to the correct name server.
2) /etc/hosts contains the correct IP address for your Scalix server.

Please note: If you have an entry in /etc/hosts that looks like this:

127.0.0.1 server localhost.localdomain localhost

You should change it to:

127.0.0.1 localhost.localdomain localhost
x.x.x.x server

where x.x.x.x is the correct IP address for the scalix server

Why scalix make a nslookup with the host name? We will never publish the host name in the internet!

x.x.x.x must be the internal IP (10.0.0.20) or the external (routed) IP ( 194.209.x.x)?

nslookup is used to check that the server name is defined in DNS. For a client-server application, this is a very important requirement otherwise the clients will not be able to access the server by name. You can have a local DNS server, there is no requirement for the internet.

x.x.x.x must be the internal IP (10.0.0.20) or the external (routed) IP ( 194.209.x.x)?

This should be the the internal IP address.
