RE: Lost Internet Access

To transfer files I save the file to \home\jan and then go to my Win Xp
machine and under the work group folder I can see the contents of the
\home\jan folder on the Debian machine. I can read the files there no
problem. As these are new files just created, the network has to working (at
least partially).

I can ping internal addresses like, but could not ping the
external address you suggested, neither by IP or Name.

Now interestingly enough I used to be able to (using Gname desktop) click on
Computer -> Network -> Windows Network -> at which point I see an icon for
my LAN's workgroup and clicking on it used to show me the computers on the
network, but now nothing.

Looking in the Syslog I found the following;

May  1 15:48:58 debian avahi-daemon[2661]: Registering new address record

What is nm_spawn_process?

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

Can you ping hosts out on the interweb using IP addresses? E.g. try:
    $ ping

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)
