Network Check Clarification

[Scottatron]

I am getting Network Check errors on install and have not been able to find a post that clarifies this well.

Here is my setup:

I have a DSL connection with a static IP for which I have pointed the domain name home.scottatron.com at. So essentially this points at my router and returns the following from nslookup:

Code: Select all

Server:         192.168.1.1
Address:        192.168.1.1#53

Non-authoritative answer:
Name:   home.scottatron.com
Address: 60.234.222.145

My server on which I am trying to install scalix has the internal IP address 192.168.1.4 and it's hosts file reads

Code: Select all

127.0.0.1       localhost.localdomain localhost
60.234.222.145  home.scottatron.com home

This setup still leads to Network Check Errors. What am I missing here?

Sorry, here's the lines from my Scalix install log...

Code: Select all

2006-02-14 02:33:36,801 ERROR Operation failed: Network check failed -- Could not find a host name in DNS that matches an IP address
2006-02-14 02:33:36,803 ERROR Operation failed: Network check failed -- IP address '60.234.222.145' associated with host name 'home.scottatron.com' in DNS cannot be confirmed as this host's IP address

What does a reverse lookup return ?

For a mail server, we expect that DNS is correctly setup so the check takes the hostname, does a forward lookup to get the IP address and then takes that IP and does a reverse lookup. If the original hostname and the resultant lookup don't match, you'll get that error.

Of course, makes sense to me now, Thanks

So, is there a way for me to tell scalix on install that I want to use a 3rd party smtp server to send my messages? I'm really just setting up a test server, so relaying outgoing messages is not a major at this stage.

[ScalixSupport]

This is configured in sendmail as a smart host.

Edit /etc/mail/sendmail.cf and change

Code: Select all

DS

to

Code: Select all

DSother.smtp.server

. You then need to restart sendmail.

I prefer to install scalix on the new build FC4 box and then deploy it on the network. I updated all related network files, but still got network check error.

Is there anyway to make the installer check the /etc/hosts, besides DNS?

Thanks.

Hi,

I believe you need to specify your local network address (192.168.1.4) in the hosts file for the domain name. I notice that your external address is specified in the hosts file instead. This could be causing the problem. Of course you will have to comment this line out and let the dns server take care of it when you go 'live'.

Cheers,
Yuri
