I just tried and those linux kernel updates for
linux-image-3.0.0-15-generic
linux-image-3.0.0-16-generic
linux-image-3.0.0-17-generic
still show up (and make me wait about 5 minutes for it to complete). (see
'a' at the end) After I removed it I tried the second command you gave me
and it said 'command not found'.
Then I tried to ssh out of the ubuntu but got the connection refused error,
so I reinstalled it and could again..

I thought that was the only way to run ssh.

all lines are commented out., (see 'b' at end) Perhaps I should create an
allowed range?
from my investigation of the man page that would look like this:
192.168.0.0/255.255.255.245 (to allow for 10 units)
is that correct?
then I guess uncomment 'paranoid' in the deny file
