How to connect to a server using pbrun in winscp

Hi,

we connect to the required host machines by running the pbrun command on a jumper machine. I am able to connect to the jumper box using the Winscp but I need to copy some files from my windows machine to the end host which connects through pbrun.

steps that we follow to connect to the end server through putty
1. connect to jumper box through putty.
2. Run the command pbrun -h 'hostname' -u 'usergrp' ksh

Can we run the pbrun command to connect to that host or is there any other means to transfer the files to that end host

It's the same as with su/sudo, see
