Ok, what you do is this:
Install all the SETI files into their own directory.
If you want the graphical version then from a terminal session within X
run
./setiathome -graphics & ./xsetiathome
the -graphics tells it to format it's output for the graphical front end
(xsetiathome).
As Abe said, it will ask you for account details the first time it is
run - that will either create a new one, or connect you to your old one.
Note - whilst you can run multiple instances of SETI, they must each be
in their own directory. Also, you can only run one with the -graphics
switch.
If you want to be able to view multiple instances graphically, try
Look@Seti (http://www.jhochwald.de/linux/lookatseti/e_index.html).
Try it - you'll like it...
