Mark,
I can PING the GATEWAY from NOVSTART but not my pc. My pc is not running a FTP
server so it should not respond, right?
Gateway

Can you ping your default gateway from the Linux system? If so, then see if
you can do a traceroute to your desktop IP address from the Linux system. If
you can get to the next hop past your default gateway, then my first guess is
that your firewalls aren't allowing incoming connections on FTP and SSH.

Technically speaking, no. But, it doesn't hurt, and if at some point you are
playing around testing something, and you decide (for whatever reason) to
uncouple the NIC, then forget to re-couple it, this will save you some hassle.
