So, as I said, you'd want networking configured with ifupdown. The
documentation is good for that, so you should not have a problem if you know
a little how networking works. If you know less than little, you might have
to do some reading. Perhaps TLDP will have some reading material.

You shouldn't have to. It's just a matter of getting the contents of
/etc/network/interfaces correct. I'm not familiar with Gnome's network-manager,
but if you post the contents of your /etc/network/interfaces I bet somebody
could help you.

You're correct. If you want to restart ifupdown without rebooting, you can issue
'/etc/init.d/networking restart' (without quotes and as root -- use sudo if
you've got it). That'll save time, especially while you're debugging.

Good luck,

I can run gconf-editor, but there is no NetworkManagerApplet
under apps.

I see that there is something called NetworkManager and
NetworkManagerDispatcher
under /usr/sbin; but when I run gconf-editor, there's no
apps->NetworkManagerApplet
entry.

continued thanks...


I might be assuming wrong things here. Do you have network-manager-gnome
installed? Are you even logging into GNOME?


If you are logging into GNOME and do not have network-manager-gnome, try
installing it and then check gconf-editor again. If you already had
network-manager-gnome, try reconfiguring it ($ sudo dpkg-reconfigure
network-manager-gnome).


If you have no need for Network Manager at all (or if the above does not
solve your problem), which actually seems to be your case, you could
also try this:


Uninstall any network-manager packages ($ sudo aptitude remove
network-manager network-manager-gnome network-manager-kde) and setting
your interface to auto (in /etc/network/interfaces):


auto eth0
iface eth0 inet dhcp

Either approach should work in theory. Please post any further doubts.


Ok, my problem appears to be resolved. Just to recap...
I am running GNOME, and according to dpkg -l network-manager was installed.
I was unable to find network-manager-applet in gconf-editor->apps.
So, I uninstalled network-manager and network-manager-gnome, and at the
moment that appears to have resolved the problem. My system now comes
up with the network enabled.
Note that I made no changes to /etc/network/interfaces to resolve this.
Thanks for the help.
Ed
