I was finally able to get SETI going by installing it from ADEPT (I'm running
Kubuntu). As soon as it was installed, I was able to input the data by hand,
from an email in my Windows partition that had the data. Once I figured out
to use ADEPT, it all just fell into place.

Just this morning, I installed Firestarter, so I am now running a firewall,
although I'm still having some growing pains with it.
