Simple Synology Linux Manual Cron Job Setup - repost

On my Synology ds211j I want to setup a scheduled job using CRONTAB. I need someone that knows Linux to: 1) Loginto the Synology server 2) Ensure that a suitable editor is in place in order to perform the crontab setup manually (there is no controlpanel setup of CRON jobs on a Synology server) 3) Use the editor to modify the crontab so that a daily cron job calls a specified link / file on the server (e.g. http:///joomla/components/com_icebooking/[login to view URL] 4) Make the necessary restart of the crontab in order to start the daily scheduled call. Competence needed: - Knowledge of the Linux / Synology ds211j server OS - Knowledge of Crontab setup manually for daily jobs According to userguides this job should be quite quick to perform for a skilled Linux / Snologyserver programmer.
