You need root (administrator) privilege to use Ethereal - it's the
act of sniffing the network that's restricted.

Open a console window and enter the command "su" (without the
quotes). At the prompt, enter the root password. Now you have a
command prompt running with root privilege. Enter the command
"ethereal", ignore all the rubbish that scrolls by, adn you should
get a working ethereal window pop up. Don't close the command
prompt window until you have finished with ethereal, or it
will disappear again.

Use "exit" to drop out of root priv at the prompt as soon as
you can - leaving a root prompt open is dangerous (mistakes
in there have the rights to do lots of damage).
