Well top and ps list ftp without the 'd' on the end |
| 27 |
as running. And ftp starts with the ftp> prompt. If |
| 28 |
that's what you mean. |

Nothing in the logs. Maybe I need a LAN specific |
| 37 |
logger? All I got is syslog-ng on both machines. |
| 38 |
|
| 39 |
There is this, which is identical on both machines |
| 40 |
with different numbers of course: |

You'll notice that last number *is* the hardware |
| 64 |
address on the remote machine(see below). So there has |
| 65 |
been some sort of communication between the two but |
| 66 |
then it shuts off. |
