Do you *ever* actually do any research before spewing onto the NetBSD
lists?  I suspect you have the mistaken impression that everyone else
on these lists is here just to provide the service of detecting your
*particularly* idiotic notions.  Cut it out already, would you?

The fact of the matter is that SSH with cipher 'none' is, though faster
than with cipher blowfish depending on your host CPU, at least five times
slower than rsh.  This difference appears to be due to cache effects of
the CRC performed on every packet, as well as extra copies required to
assemble the relatively complex SSH packet format.

If you want to not enter your password, and you don't give a damn about
security (because with SSH and cipher none, you aren't getting any!) just
use rsh and .rhosts.

  foolish and bewildered and astray: can any man?
