Hi
there is no UC4 script function to transfer files - no matter if an agent is installed or not.
As the target server does not have a unix agent installed, you can't use a common File Transfer job.
The only solution is using means of your OS to transfer the file such as FTP, SCP, RCP, Samba, etc...
This can be done with a WIN Job or a Unix job from UC4.
