The Interface Does Not Exist
 
eth0
When I try to configure it to allow access to my Windows network, the "Wired Connections" in Network Settings look like Modem pictures, and I can't update the "picture", even though the settings can be updated. So I try Network Tools, and BOTH devices give me the dreaded "The Interface Does Not Exist".

I am a real Ubuntu newbie, although comfortable with computers overall... I would appreciate for your help.

/sbin/ifconfig command will show you the interfaces that exist.

It shows me this

Your ifconfig from above shows that your ethernet address is up and pulling a valid IP address.
You should be able to
Code:
$ ping 192.168.179.128
to verify that the interface is working.
then
Code:
$ route
or
$ ip route
should show the ip address of the default gateway and you could ping that address to verify connectivity to the network.

What are the names of the Interfaces that are showing as "non-existant"?

Thanks so much John. I had installed Ubuntu on vmware . What I did was to remove the ethernet adapter and installed a new ethernet adapter and I selected Bridge type adapter from VMware. Then I was able to ping.
The second problem then I faced was that I was not able to update ubuntu ,the mistake was that I did not configure network proxy. Now everythingh is working fine.
