When you tranfer files back and forth between machines: Do you use their
names or their IP addresses?

So, basically, you internet connection is OK, but that specific machine
has got a problem.

No error messages at all? you might have missed something - check
/var/log/syslog - things like filesystem repair and the like might be
interesting...

Can you ping hosts out on the interweb using IP addresses? E.g. try:
$ ping 82.69.56.225
Also try:
$ ping galileo.jorgensen.org.uk
If the first command fails, then you have a network connectivity problem
- time to check that the network interface actually has a (correct) IP
address and that routing and firewalling doesn't get in the way.
(obviously you'll check the cable first, right? :-)
If the first command works, and the 2nd fails, then you have a name
resolution problem - and you should check /etc/resolv.conf.
If you're using dhcp (and it sounds like you are), dhcp should take care
of setting up /etc/resolv.conf

we have /sbin/ifconfig (note that /sbin isn't in the path for normal
users) which will show the current configuration of the network
interface. If the interface is connected and set up correctly, it
should list a network address.
I cannot remember how to control dhcpclient off the top of my head -
hopefully somebody else can help here. But this might help:
# ifdown eth0
# # wait for a bit
# ifup eth0
(assuming that eth0 is your network interface)
