Aha, so here goes nameservers definitions on Debian Lenny?
I remember on Debian Etch I used for this /etc/resolv.conf file.

So the form is:
nameservers 2.2.2.2 3.3.3.3 4.4.4.4 ??

No.

I can't to paste here the exact ouput of 'ifconfig -a' command but have
the following interfaces: lo, eth0 & eth1. I use another PC Box to mail
here for help.

So I find the cause of my problem, I think! eth1 is the usb-ethernet
device and not eth0. eth0 is there because I used it when I installed on
this PC Box the present Debian Lenny system, but through an Ethernet
card. But now I want to configure this Box through USB port of a Cable
modem, so that's why is there the eth1 interface.

So, when I give today morning the MAC address to my ISP, I give the
Ethernet card MAC address, instead of the USB-Ethernet aka eth1 MAC
address to associate it with my new static, public IP address! 

I will correct this soon as possyble (here was a storm and my ISP is
busy now ;).
