I'm having 2 problems with cron. The first one is that the root cron doesn't
seem to be running. I have 3 tasks entered and none of them seem to run. The
second is that I'm no longer able to edit my user cron when logged in as the
user.

What could be causing these?

Take the file that you're calling with crontab, and make sure you have valid
CR's at the end of each line.. Look at it with a good editor like vim, for
example. Also make sure the items you have listed in the file are executible
(chmod a+x filename). Often I messed up the fields when I started using
cronjobs, so you might also check that.. this is an example of a cronfile for
crontab that works here:

03 0-23 * * * /home/bbbs/mailvlad.sh
07 0-23 * * * /home/bbbs/tonymail.sh
08 0-23/6 * * * /home/bbbs/jdavismail.sh
10 23 * * sun /home/bbbs/mail/forsven.sh

The first line is executed every hour at 3 min. past the hour.
The third line is executed every 6 hours at 8 min. past the hour.
The last line is only executed on Sunday at 10 min. past the hour.

You have to add the user to wheel group I believe in /etc/group:

wheel::10:root,janis,bbs

Take care,

here is the root crontab in question :

# MIN HOUR DAY MONTH DAYOFWEEK COMMAND
0 0 * * * /usr/bin/ntpdate -b time.nist.gov
0 0 * * * /usr/bin/emerge sync
30 0 * * * /usr/bin/emerge -Upv world | mail -s 'emerge -Uvp world' downtime

my user account is in the wheel group. but i think i may have tried to manually
add it when i did it. is there a command i should be using to add a user to
group?

So anyway, it was like, 23:52 CEST May 05 2004, you know? Oh, and, yeah,

Nothing to do with that in this case, I think:

'man crontab'
-----8<-----
If the allow file exists, then you must be listed therein in order to
be allowed to use this command. If the allow file does not exist but
the deny file does exist, then you must not be listed in the deny file
in order to use this command. If neither of these files exists, then
depending on site-dependent configuration parameters, only the super
user will be allowed to use this command, or all users will be able to
use this command.
[..]
FILES
/etc/cron.allow
/etc/cron.deny
----->8-----

Add your user name (and you might need to add root too, if you create
the file) to /etc/cron.allow and you should be able to create your
own, personal jes^H^H^Hcrontab.

Your user has to be in the cron group to use crontab. Also check you don't
have it blocked in /etc/cron.deny or cron.allow. The usemod command is
usermod, read the man for more info.
