please help me connect to BUBBA

[nb000]

Hi everyone.

I have a BUBBA mini-server and I run run rtorrent on it.
I would like to manage it from a winXP PC.
Here comes the problem.
It does not work :-(

Details:
- OS: win XP sp2
- rtorrent: 0.7.9 (with xmlrpc-c-1.06.27)
- libtorrent: 0.11.9
- n2hell: 0.5-20080528

.rtorrent.rc intresting parts:
directory = /home/nb/download
session = /home/nb/session
port_range = 6666-6666
scgi_port = 127.0.0.1:5000

BUBBA IP: 192.168.2.102
winXP PC IP: 192.168.2.100

n2hell setup params:
id: bubba
on different machine
startup cmd: screen -dmS rtorrent rtorrent
cfg path: /home/nb/.rtorrent.rc
ssh host: 192.168.2.102:22
for authentication use: login and password
user: nb
pass: ******* (not shown here :-)
and the checkbox is checked before nb

When I try to connect the log is the following:
C:\Instant\n2hell>java -jar "C:\Instant\n2hell\\n2hell.jar"
