You are missing a star '*' character before '/2' near the beginning of
the line immediatelly above. Try this instead:
*/2 * * * * root /home/ken/rn
Then make sure /home/ken/rn is executable.
I'd also suggest moving your `rn' script in `/root/scripts/rn' and
making `root:wheel' its owner. The crontab entries from `/etc/crontab'
are executed with root permissions, so giving the user `ken' control
over what runs is creating a backdoor for anyone who gets access to that
non-root user account.
