    |- Charlie,
    |- 
    |- That looks like our winner.  As you can see, you have three interfaces.
    |- The "lo" interface is your loopback interface.  This should be
    |- configured with the IP address 127.0.0.1.  Apparently it isn't.
    |- 
    |- The quick fix is to run "ifconfig lo 127.0.0.1" as root and you'll be
    |- able to ping localhost.  I'm not sure you'll be able to configure CUPS,
    |- as I think this is a name resolution issue as indicated in the CUPS
    |- logs.
    |- 
    |- There is a reason for this however and I hope someone else will chime
in
    |- here with some comments.  In your email off list your /etc/hosts file
    |- has the following line at the top:
    |- 
    |- 127.0.0.1 localhost
    |- 
    |- Let's change this to:
    |- 
    |- 127.0.0.1 localhost localhost.localdomain ariestao
    |- 
    |- I haven't seen your /etc/network/interfaces file, but make sure you
have
    |- a stanza in there somewhere along the lines of:
    |- 
    |- # The loopback network interface
    |- auto lo
    |- iface lo inet loopback
    |- 
    |- I *think* when your lo interface is restarted it should be assigned the
    |- address 127.0.0.1.  Just for further verification, can you make sure
    |- your /etc/nsswitch.conf has a line like this:
    |- 
    |- hosts:          files dns
    |- 
    |- We want to make sure that when CUPS starts and looks up the host
    |- "ariestao" it is configured to look in "files" (/etc/hosts) where it
    |- resolve correctly.
    |- 
    |- Anyway, once you have verified nsswitch.conf is correct, restart CUPS
    |- and that name resolution error should be gone.
    |- 
    |- Post again with your results.

Jeff, you have it. Absoloominlootly marvellous, you are a legend.

I had to change nothing at all, and you just caught me in time. I went out to
cut some Tagasaste for the sheep, and thought, before I reinstall, I would
have another look. There was your post.

I just did as you said:-

ifconfig lo 127.0.0.1

And then in Firefox tried http://localhost:631 and there it was, CUPS up and
ready.

My /etc/hosts file is:- 

127.0.0.1 localhost 
<my netaddress for this machine> ariestao

Thanks to Mirko, and the way to find the address for this machine, because of
my doubt, and it still not working to Clive.

My /etc/hostname file is:-

ariestao <my netaddress for this machine>

I think that's all that is different. Have a worked on several files, but have
returned everything else to "as was" when it didn't work.

Now I will configure my printer and see if that works as it should.

I have to thank you for your time and perseverance, and timing as well.

Thank you very much indeed.

Charlie
