Ftping files through scp

[Hyperblaze]

I'm in the process of writing a shell script with copies files from one linux box to another using scp. I wish to run this through a cronjob so it cannot be interactive.

This is what I have so far.

#!/bin/sh
PASSWD='passswd'
dateset=$( date | awk '{print $2 $3 $6}')
for dates in $dateset; do
dateset2=$dates
done
cd /home/user
scp -r user@host:/home/user/$dateset2.db.gz . << END_SCRIPT
quote PASS $PASSWD
END_SCRIPT
exit 0

it still asks me for the password though.

It works if I use ftp (but I'd rather use something more secure)

Might anyone be able to offer suggestions?

Google "SSH public key" (which works for scp/sftp also).

you can also use sftp -b and supply a batch file (read the manpage for more info).

Although you should be using key's anyways with ssh because its more secure.

another vote for keys

otherwise I think expect might be a better language to script this in

Yeah. And if you're using unencrypted private keys, try to set up a seprate user on the other machine that doesn't have write access to anything except the directory you're scp'ing too. I think there's also a way to restrict what programs can be run when logged in via certain keys (in the authorized_keys file on the line for the key?)
