2 things:

1) You don't need to put the root user in the cron.allow file, root is all powerful. I initially thought you were talking about a normal user.

2) Another way of putting the username into /etc/cron.allow (as root):
echo "username" >> /etc/cron.allow

After that, just in case:
chmod 600 /etc/cron.allow

Hope this helps.

Hi, following is occurs
node2@node2-prudence:~$ echo "username" >> /etc/cron.allow
bash: /etc/cron.allow: Permission denied
node2@node2-prudence:~$ echo "node2" >> /etc/cron.allow
bash: /etc/cron.allow: Permission denied
node2@node2-prudence:~$ chmod 600 /etc/cron.allow
chmod: cannot access `/etc/cron.allow': No such file or directory

node2@node2-prudence:~$ sudo su
sudo: must be setuid root

Thanks

Hi,

As I stated before (post #8): it looks like something was not installed correctly (the setuid thingy). Maybe an Ubuntu user can help you with that one.

If you have the root password you can also do: su - (and type the root password).

You do need to have root access to create/change the /etc/cron.allow file, so the setuid problem needs to be fixed first (if the su - option is not possible).

Hope this helps.

Thanks druuna

Hi again,
