Hello Ringo,

     I am having (or should I say, "was having") the same problem with my
laptop. I only discovered this error when I could not set up remote
printing from my laptop. I have a Dell Inspiron 4000 Laptop with Fedora
Core 3rc3 installed on it. I also have a wireless card attached to it. I
am able to connect to the internet and everything seems to be okay except
for the fact that I cannot see the DHCP local address when I go to the
command line but I am getting a similar error which says "Local Host
Unknown". The wireless card applet shows the DHCP local address but when I
ping the localhost (that is, the laptop) , I get the "Local Host Unknown"
error. The only difference between my setup and yours is that I am on a
local are network and your computer is a standalone computer. What I did
to get the remote printing up and running again was to go back to putting
Mandrake Linux 10.0 back on the print server (the desktop where the printer
is attached) where Fedora Core 2 was previously running.

     When I get more info on this error, I will notify you.
