So you see no SYN requests to your server on port 21 |

Chrooting is not going to get around needding root access to listen on |
| 27 |
port 21. Plus don't you still need to be root to chroot? |

This is my theory but I haven't verified it. Bittorrent clients are |
| 32 |
programmed to listen/connect to a range of ports by default (I think it |
| 33 |
starts at 6882). Your client is connecting and saying "connect to me on |
| 34 |
port 21". The other clients see this but it's not in their IP range so |
| 35 |
they refuse to connect to you. You might be able to tell your client to |
| 36 |
listen on tcp/21 but that doesn't mean everyone else has told their |
| 37 |
clients to connect. |
| 38 |
|
| 39 |
But if you are sure this *has* worked then that would make my theory |
| 40 |
incorrect. Like I said I've never verified it, but that seems like the |
| 41 |
likely scenario. |
| 42 |
|
| 43 |
The other scenario is if you're not even seeing SYN requests is that |
| 44 |
requests are being blocked to your computer from that port, possibly by |
| 45 |
your ISP. But again if this were the case then it should also be the |
| 46 |
case for Windows, Knoppix, etc. |
| 47 |
|
| 48 |
Can you verify your claim (i.e. go into knoppix or whatever, run |
| 49 |
rtorrent on tcp/21 and verify via netstat that clients are connecting to |
| 50 |
you on that port)? |
