Please try my suggestions the actual way I suggested doing them before declaring that cron isn't working. You're supposed to use the crontab command, not edit files by hand! This will allow it to warn cron that the table's changing, as well as potentially warn you if you have any syntax errors in your crontab that'd prevent it from running.

There may well be additional problems preventing cron from running your script, so I'd also recommend sticking to the 'touch' command until you get that working. One problem at a time. Try calling touch with the absolute path, whatever it may be for your system.

What is your system, anyway? Last time I used ipkg, it was on a wireless router...

No crond is nt running, only cron.
I am quite new to this, I do not know the diff between cron and crond.
Code:
$ ps -fe | grep cron
  741 root        608 S   /opt/sbin/cron
18436 root        504 R   grep cron

In the log I have this
Code:
$ ls -la /var/log/cron/
drwx------    3 root     root         1024 Jan 14 15:13 .
drwxrwxrwt    4 root     root         1024 Jan 17 11:50 ..
drwx------    2 root     root         1024 Jan 14 15:13 crontabs

 cd  /var/log/cron/crontabs/
$ ls -la
drwx------    2 root     root         1024 Jan 14 15:13 .
drwx------    3 root     root         1024 Jan 14 15:13 ..

My system is a Western Digital 4 disks RAID1 ShareSpace.
It runs Linux.
I am programming a ssh backup system, I also have problem with the rsync public private key stuff.

There is a link to this :mybookworld.wikidot.com/sharespace
I did what they said but since I am stuck with this cron issue.

Does your system not have crontab -e, then?

Is your root user in the cron group, did you check?

etc, etc, etc.

Thanks Corona688.
yes I use crontab -e
there is no cron group available here since usermod is not on the system, neither in ipkg.
Is there a way to check this group permission by hand?

Yes, the method I suggested earlier, checking the contents of the /etc/group file. It is a text file, so it may be possible to edit it manually, if you're very, very careful.

I did not get that message
I try and get this:
Code:
$ more /etc/group
root:x:0:
daemon:x:1:
bin:x:2:
sys:x:3:
adm:x:4:
tty:x:5:
disk:x:6:
wheel:x:10:root
utmp:x:43:
staff:x:50:
admin:x:98:admin
nobody:x:99:
ftp:x:14:ftp
users:x:100:
nfsnobody:x:65534:
jewab:x:1000:

What do you recommend?

Hmf... You don't even have a cron group, which makes this awkward. Most of the suggestions I'd make wouldn't apply to your embedded system. Maybe it's not even supposed to have user cron tables.

You could try editing the global /etc/crontab instead of the user ones. Note that its syntax is slightly different than the usual crontab, it takes the usual five time parameters, then the user, then the command, like so:
Code:
*/10  *  * * *  root    test -x /usr/sbin/run-crons && /usr/sbin/run-crons

If you have to create the file, be sure to chmod 644 it after, some crons are very picky about what permissions it wants. And you may have to restart the system for it to start using it.
