ssh through cron scripts.

[knome]

I'm having issues setting up cron scripts that log into a server automatically via ssh.

I created the automatic ssh login using this:
http://www.ccp4.ac.uk/peter/programming/automatic_ssh_login.html

i followed this how to in order to set the the cron job:
http://www.tech-geeks.org/contrib/mdrone/cron&crontab-howto.htm

I tested the scrip manually but it still requires me to enter the password for the ssh login. But if i manually type it in the console it logs me into the server instantly without a password.

So how do you get the auto ssh login to work inside of scripts?

How do i check to see if my cron job has been added?

here is the scrip i am trying to run

#!/bin/bash

rsync -v -r -z -u --exclude '.DS_Store' user@myserver:/media/extra/backups/projects/ /Users/myusername/Documents/Projects/

Here is the code that i injected into the crontab

0 * * * * /etc/periodic/hourly/*

I do this myself. Here's my command:

rsync -avz -e "ssh -i my-rsync-key" user@domain.com:folder ./

It doesn't look like you're making use of a key when logging in. Notice my piece for my-rsync-key. Here's the article I used when I originally was figuring this out. Maybe it can help you.

Thats what has me confused. I did this about 9 months ago with a different computer and the same server for backups and i don't have a line like that in the cron file and it works just fine. I have absolutely no idea what i did.

Well now i have to start from scratch. I was messing with it and now not only is my old one not working but i can't get any type of auto login to work now.

Use:
crontab -l [optionally -u username]

Keep in mind that every user has their own crontab file, and their own .ssh/authorized_keys file

It sounds like you may not be running your script with the same user that is allowed in the remote authorized_keys
