Problem with F-secure Reflection server

[hzhengyang]

Hello, I'm doing my college internship attachment now... and I've been stuck with this problem, hope this is the appropriate place to post it :

I have to set up a F-secure Reflection client and server, to transfer files using bourne shell scripts. The client runs on a UNIX platform, while the server runs on a Windows XP Pro platform. Mode of authorization is via public keys.

Attached is the log i get when i run my script.
It always gets stuck, saying "server rejects signature". Can anyone kindly point me in the right direction, regarding what might have caused this problem??

Thanks!
