you need to enable the rsh on the filer side using options command
and if u have password for ur root user, then no output u can get...this is due to rsh cannot specify the password for user.
so the workaround is to use plink or other remote shell which can specify the password for user.
u need some basic knowledge about coding. u need to change the .pl source code
change the rsh to plink
and put the password in the command line.
another workaround is temporarily removing root password, run the .pl and change the password back.
