your other two questions when I figure out how to get to ifconfig and ip-addr.
for some idiotic reason ( and not a good one) novell dose NOT have you make a separate root account with it's own password
( a pet peeve with OpenSUSE 12.1)
so did you make a root account WITH it's own password
open a terminal ( r-click , actions,open terminal here)
your root password when asked
there should be a listing for "io" -- no network connection ( unpluged )
my cable connection is listed as "eth_s0_0 "
you can also use the GUI "yast"
there is a "icon where the MS windows "start" is ( assumming you ARE using the DEFAULT kde4 desktop )
click on yast
type in your root password
then in that gui menu you can get to the network gui
