Since that machine is now running Ubuntu, I had to do the same thing, but use a shell script with SCP and SSH instead. SCP pulls the files from the email server, and I then use SSH to clean up the files once I have them copied. The problem is that when you use SSH or SCP you are normally prompted with a password right?
Well to remedy this all you have to do is generate a key pair to use for authentication instead. To do that do the following from a terminal as root (sudo su):
- ssh-keygen -t rsa
- ssh-copy-id -i ~/.ssh/id_rsa.pub user@remotehost
- ssh-copy-id -p PORTNUMBER -i ~/.ssh/id_rsa.pub user@remotehost
Once that is done you can now run SCP or SSH without being prompted for a password. Here are the commands I added to my shell script to first pull the backup files I wanted, then once I had them downloaded SSH deletes them from the server:
scp -P PORTNUMBER user@remotehost:/bak/*.cpt .If you are wondering what the *.cpt extension is, I explained that I first encrypt my backups in a previous post. Also the '.' at the end of the first command assumes you want the files downloaded to you current directory. You need to change that if you want it downloaded somewhere else.
ssh -p PORTNUMBER user@remotehost rm /bak/*.cpt
Anyway, now I have my script being run as root weekly via cron on my home computer, and once again I have some peace of mind!
