Subject: Automated ssh scanning

Hey Ron,

Guest isn't a admin so they let the tool get in. But the real questions
is, how does it get root access on a fully patched server? It appears to
use a local exploit to gain root access. This is a problem.  

Sorry about the eariler e-mail, I haven't had my coffee today. Trying to
cut back and spend that money on IT security =P

the real thing this user most likely suffered from was the weak account
passwd double, guest:guest.  Now, if the admin and other account were
setup with strong passwd's and this account was either setup with a
strong passwd or not setup at all might be a better test of the
stability of ssh and the debain setup in question.

Thanks,

Ron DuFresne

OK, so you're a Ph.D.  Just don't touch anything.
