Im a newbie, so be patient
Im using the vmware version of backtrack. I start it without problems but i cannot connect to internet. Im using the l0 device. Its the default one, i think. With backtrack 3b i didn't have this problem.
Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69
For that matter you may want to make sure you have settings. The standard commands still apply in a vm.
ifconfig eth0 up
the lo interface is the loopback interface, use the eth0 interface instead.
or ath0 if you have the Atheros wifi.
The command ifconfig -a will tell you all of your interface devices, even if they are powered down.
