Well top and ps list ftp without the  'd' on the end
as running. And ftp starts with the ftp> prompt. If
that's what you mean.

Nothing in the logs. Maybe I need a LAN specific
logger? All I got is syslog-ng on both machines.

There is this, which is identical on both machines
with different numbers of course:

sarawak heathen # tcpdump -v

You'll notice that last number *is* the hardware
address on the remote machine(see below). So there has
been some sort of communication between the two but
then it shuts off.
