Re: Printer & localhost:631 -- Don't Give Up Yet

these words:
|- 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

It is all you say Jeff, I have removed the surplus lines that I added to
/etc/hosts and /etc/hostname
hosts: files dns is in my /etc/nsswitch
Thanks for all your help. I am now able to connect to localhost:631 and the
printer administration etc.
It is really appreciated.
Now I have to learn a bit more about firewalls in Debian..... so to some
reading.
Charlie
