RE: can't bring up eth0 correctly
I should have written /etc/network/interfaces.
In reading a few things on the net, a lot of people suggested to have the
autho eth0 commented out. This is for a laptop. I'm coming from redhat,
and once dhcp is set, you can more or less leave it that way.
All that I'm trying to do at the moment is get eth0 up and running. I get
alerts saying that there is no such process or device.
When I restart networking, I expect to see eth0 come up, but it doesn't.
In /etc/network/interfaces, I have the following information
I am basically looking to configure for dhcp only. I have removed netenv,
because it did not seem to work too well for me. Maybe misconfigured.

Shouldn't that be "/etc/network/interfaces"?
I'm a little confused about what you are trying to do, and what exactly is
failing. The line "auto eth0" that you commented out is the line that
causes the interface to be configured on boot. It is quite common to not
want the interface to be configured on boot for a laptop. However, if you
remove the 'auto' entry, you need manually bring up the interface using
'ifup eth0'. Have you tried doing that?

Did you bring up the interface after setting the address? Presumably you
are using ifconfig to set the address. Try "ifconfig eth0 up".

Your /etc/network/interfaces file should look something like this:
#auto eth0
iface eth0 inet dhcp
You should then bring up the interface by doing:
ifup eth0
If the interface fails to come up, check your system logs for error
messages.
I think you might need to post a bit more information before anyone can be
any more specific with an answer.
What is the network chip?
Is it pcmcia/pccard or internal?
What are the contents of your /etc/network/interfaces
What commands are you using to set the IP address?
What error message are you getting when you try to set the default route?
What related error messages are you seeing in your syslog?
What dhcp client do you have installed?
