Hi,
I am not too familiar with csh, but it appears to be fine.
Are you using a key based authentication that works for the user that the
script runs under? You could test by trying the scp line from the command
line.
How is roots password provided (or is it key?)
Is root allowed to access the remote systems via ssh?
