Re: Lost Internet Access

Please don't top-post - it makes it really difficult to follow a
conversation (I know. outlook encourages people to do this, but mailing
list etiquette is different. And pre-dates outlook...)

OK - via samba running on the debian box.

Then you *do* have a network connectivity problem...

Things to look at:

routing: the box should have a default route pointing towards your
(adsl?) router. Running any of:
    # netstat -rn
    # route -n
(-n to force numeric output rather than trying to resolve things to
hostnames) should reveal the routes. The default route is the one with
a destination of "". 

Firewall: if the firewall is blocking traffic similar symptoms would
    # iptables-save 
If this gives any output, then some firewall rules are active. This
*could* cause problems ...

Router: Has it got any configuration to allow/deny access to the outside
world, e.g. by IP or MAC address? Worth a quick check...

( I presume you mean "Gnome", rather than "Gname" ? :-)

Interesting. This points towards something changing on the box. I know
you mentioned earlier that nothing was changed. But what if it only took
effect upon reboot?  ... What changed *before* the reboot?  (packages
installed/removed etc)

I doubt whether you *need* avahi in your setup. But it shouldn't get in
the way either though...

Interesting. nscd is a name service caching daemon:    

Was nscd removed recently? It appears that your problem is IP
connectivity, and not name resolution, so nscd shouldn't matter (yet).

probably the name of a function inside NetworkManager...

Well, I'm sure they appreciate the free advertising you give them.
Falling on deaf ears here though...
