Help with cron

Both myself and a colleague have had no luck in trying to figure out how
to get cron up and running. I’d like to run a process at 1:00am every
day. Here’s what I’ve done so far:

  1. Logged in as root.

  2. Created a cron.allow file in /var/spool/cron and added the following
    entries:

root
joeuser

  1. Started cron (/usr/sbin/cron &)

  2. Still logged in as root, created a crontab file (crontab -e) with the
    following entry:

          • (echo -n " "; date; echo) >> ~/test.txt
  1. Still logged in as root, created a crontab file for joeuser (crontab
    -e -u joeuser) with the following entry:
          • (echo -n " "; date; echo) >> ~/test.txt
  1. Checked the home directories for root and joeuser, and the test.txt
    entries are both there and are being updated every minute as expected.

  2. Logged in as joeuser and tried to edit the crontab file (crontab -e).
    I get a warning saying that cron has not been started and a memory fault
    causing a core dump.

Can anyone help? Thanks in advance.
