Re: Unable to edit or list crontab
What does your 'crontab' command look like?
This is from an 11.11 system, but the permissions and ownership should be similar though the file size / date will differ.
root@prod1:/
# which crontab
/usr/bin/crontab
root@prod1:/
# ll /usr/bin/crontab
-r-sr-xr-x 1 root bin 28672 Aug 24 2006 /usr/bin/crontab

Re: Unable to edit or list crontab
Try restarting cron:
# /sbin/init.d/cron stop
# /sbin/init.d/cron start
Then try the cron -l command again.

cron stopped
cchost0[133]/ #/sbin/init.d/cron start
cron started
cchost0[134]/ #crontab -l
cchost0[135]/ #date

Re: Unable to edit or list crontab
Well, here's your problem.
#ll /usr/bin/crontab -r-sr-xr-x 1 root bin 0 Dec 22 2009 /usr/bin/crontab
Somehow your crontab executable has been wiped out. It is zero bytes. That will definitely not work.
You need to restore it from a backup.
