Forgive my obtuseness.

My workstation is, let's say, DeskBox.  At work, I log onto DeskBox
directly, and from there I use a terminal windows to ssh to the other
development machine, let's call it DevBox.

When I work from home, I use the Win7 VM to PuTTY in to DeskBox, and
from that pseudo-terminal window attempt to ssh into DevBox.  This is
where the pass phrase and password demand occur.

The connection is always between DeskBox and DevBox.  The only
difference is whether I am sitting at the desk and connected directly
to DeskBox via its keyboard, mouse, monitors and terminal window, or I
am logging into DeskBox remotely (via my Win7 VM and PuTTY).

Thanks.
