scp host1:file1 host2:file2 -> Permission denied??????

[Daniel Tourde]

Hello Ben,


Thanks for your answer.

Yes. I know that, considering that I am already on host1, a simple "scp 
file1 host2:file2" could also do the trick, somehow.

This is were you are loosing me.
Is there a fondamental difference between:
scp host1:file1 host2:file
and
scp file1 host2:file ?

If yes, what is it then and how a system is supposed to be configured to 
make it work whatever the user types.
