What command do you try to execute? Try specifying the username 
explicitly (this may be a good idea anyway if you are going to run it as 
a cronjob):

$ scp [options] <fileglob> <user>@<remotehost>:<destination_path>

Works for me without the hosts.equiv part.

If you are going to run this as a cron job, consider using rsync to 
speed up the transfer.

If you really want to know everything you don't need to know, O'Reilly 
has (yet another) book on SSH.
