Network Check Failure

[fuzzbuzz]

Hello.

I am installing Scalix on FC4, but am unable to do so because i get the following errors:

Network check failed - Hosts file not configured with fully qualified domain name
Network check failed - Invalid FQDN 'amd2800'
Network check failed - Could not find a host name in DNS that matches an IP address
Network check failed - Could not resolve host name 'amd2800'


No idea what that means. Suggestions?

Thank you

Hi. Please see this link for a description of what a fully qualified domain name is: http://en.wikipedia.org/wiki/FQDN

Then see this link for a description of your Hosts file: http://en.wikipedia.org/wiki/Host_file

So, what you need to do is make sure your Scalix Server's FQDN is in your hosts file.

Thanks,
Rachel

I am also having this problem, I have added the following information to the hosts file but it still does not work.

192.168.0.90. mail.kennedysgroup.com. mail.

Any Ideas?

Hi Sascha,

I have checked the forum and found the correct layout for the hosts file and now the the following hosts file:

127.0.0.1 localhost.localdomain localhost lisbon
192.168.10.90 mail.myleskennedygroup.com mail

Still not working.

Hi,

these are very basic DNS issues.

Try this:

On a command line, type in

nslookup

then type in your hostname. Does it return something? Post it here.

Cheers,

Sascha.

Kev,

Can you post the error messages that you are seeing.

The main thing that concerns me is that your localhost (127.0.0.1) entry in /etc/hosts is not correct.

It should read:

Code: Select all

127.0.0.1 localhost.localdomain localhost

You seem to have an extra "lisbon" in there.

This is a very annoying feature that the RedHat installation has if you do not enter a domain name when you run the OS install.

Cheers

Hi Sascha,

I get this on a nslookup:

Server: 192.168.10.1
Address: 192.168.10.1#53

Non-authoritive answer:

name: localhost
address: 127.0.0.1

Cheers,

Kevin

Hi Dave,

I have ammend the hosts file to read as you suggested. I'm still getting the FQDN error and still can't get Internet access etc. I was getting Internet access until I started messing about with hosts file, if this helps.

Cheers Kev

Can you post the exact error messages you are getting from the installer as this is going to help us a great deal. At the moment, you're only showing us what you have in /etc/hosts rather than what the installer thinks is the problem.

Also can you tell me what problems you are having with internet access. The /etc/hosts file does not affect network traffic in that respect. The file /etc/resolv.conf defines what name servers are to be used, if any. The commands route and ifconfig will show you if you have any problems with your network configuration.

Cheers

Agreed. DNS entries are probably not right ---- unless 10.1 is a dns server. But that's where it is trying to resolve hostnames (based on nslookup results).

Hi All,

Error message is as follows:

Network check failed - host file is not configured with fully qualified domain name (FQDN).
Network check failed - Invalid FQDN 'localhost.localdomain'
Network check failed - Could not find a host name in DNS that matches an IP address.
Network check failed - IP address assicated with host name 'localhost.localdomain' is 127.0.0.1.

Ifconfig command give me the IP address of 192.168.10.90, which I set-up as a static IP address. DNS server 192.168.10.1, i can ping this IP. I can ping 192.168.10.90 from another PC on network. Tried pinging www.google.co.uk and IP of google and can't.

The /etc/resolv.conf contains the following information:
nameserver 192.168.10.1
search localhost

thanks,

Kev

Please tell us what your local IP address is and what nslookup returns when you type that in.

Cheers,

Sascha.

Hi,

The following information is given on nslookup of server IP (192.168.10.90):

Server: 192.168.10.1
Address: 192.168.10.1#53

** Server can't find 90.10.168.192.in-addr.arpa: NXDOMAIN **

Thanks,
