Nick I think you are misunderstanding what Ray is asking. scp (without the -i <keyfile> arg) will ask you for your SSH password. BUT, the keyfile itself can be generated to have a password also! On the SSH server as the user you want to scp from apache as, run "ssh-keygen -t dsa" and it will generate a key file in the current users ~/.ssh/ folder named id_dsa and id_dsa.pub As part of this generation, it will ask you for a password for the KEY, this is NOT the SSH password. If you want to run SCP without any passwords, you need to just hit return at the password prompt so that it will generate the keys without a password. You will want to put the id_dsa.pub file on the web server and make it readable by Apache. Test it yourself as a normal user on the webserver and double check that it doesn't require a password. Hope that helps Col.
