I istalled a dhcp client (dhclient3) in order to let my computer
interact with a router-switch (Netgear RP614) that contains a dhcp server.

The output of "ifconfig eth0" is:

This seems in order with the instructions from Netgear. Nevertheless,
when I try to reach any Internet site, I get an answer (helas I didn't
write it down) that lets me think that its name cannot be resolved. In
effect, I didn't give any piece of information concerning a DNS server.
The netgear unit also uses dhcp to get the ip address of its external interface from your ISP. You would normally expect as part of that process for it to be given the nameserver address it uses.
When it dishes up a IP address for your machine - it gives it self as the nameserver, but acts as a cache between you and your ISPs address.
If all is working, then dhclient on your end should then fix up so that you use the nameserver address (I can't remember if it writes to /etc/resolv.conf). You should be able to see what its picked up by logging on to the netgear router with your web browser and selecting the Router Status option. This lists the nameservers it thinks your ISP has given it.
Here is one problem. I cannot actually log on the netgear router. I tried to do it via Mozilla, but I got the answer "connection refused". 

Nevertheless, when I ping the netgear box ("ping 192.168.0.1"), I get:

PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: Echo Request

64 bytes from 192.168.0.1: icmp_seq=0 ttl=255 time=17.5 ms

--- 192.168.0.1 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 17.5/17.5/17.5 ms

So there must be something my ignorance prevents me from undestanding.

Thank a lot,
Piero.
