[PythonCE] PyCrypto binaries -- nearly there..

[Marc Horst]

Hi Alexandre,

Thanks for your help! I made the change to Agent.py and my PDA is now 
able to connect to the notebook, but then it crashes (see the logging 
below):

 >>> execfile('\\Flash 
Disk\\Programmabestanden\\Python25\\Lib\\demo_pda.py')

I'm a newbee in Python and with ssh, so I can't make any conclusions 
from this message; hopefully you can ;-)

Furthermore I tried the program you sent me as a replacement for demo.py 
(I just changed the servername, username and password; that was all I 
had to change, right?), but this didn't work (I tried it on my PC). When 
trying it in IDLE, it gives the following message:

...     stdin, stdout, stderr = client.exec_command('ls -l')

Could you please give me some help on this one too, as I would like to 
avoid using the demo.py script ?


Thanks a lot,

Marc
