Debian Configuration :: Cron.daily Not Running Daily On Laptop?

May 31, 2011

I am running on a laptop and cron.daily is set to run at 0625 So I wonder what happens if my machine is not turned on at that time.. At that rate it could also be off for the other periods as well (weekly, monthly) Is there solution that will allow them to run once they are online after the appointed time? using a cron entry that runs every 15 or 5 or 1 minute.

Fedora :: No Output From Cron Jobs In /etc/cron.daily

Jan 29, 2011

I have added some executable scripts to /etc/cron.daily but don't get the stdout/stderr output from them as mail (or anywhere else I have found). At least one of them is running (because I can see that it has added a file to the disk).

The peculiar thing is that I do get the output from /etc/cron.daily/0logwatch (part of the logwatch package) as an email each day.

The MAILTO line in /etc/crontab is "MAILTO=root" (unchanged from default). Same for /etc/anacrontab.

I do have an alias at the end of /etc/aliases which redirects root's mail to my own account, but this alias works fine for mail I send manually. (It also appears to work fine for the output from the file /etc/cron.daily/0logwatch.)

CentOS 5 :: No Items From /etc/cron.daily Run On 5.3

Oct 26, 2009

I'm having a very strange issue with cron on centos 5.3 64-bit. I have 3 cron scripts in /etc/cron.daily which run backups. They are as follows:







The contents of the 3 /usr/local/bin scripts are ...

synbak -s srv1 -m rsync
rsync -av --delete /data/backup/srv1/* root@::share/srv1/

To explain this, the 1st active line does a synbak backup and the 2nd active line rsyncs the backup data to a remote server.

synbak -s srv2 -m rsync
rsync -av --delete /data/backup/srv2/* root@::share/srv2/

Ubuntu Servers :: 10.10 - Daily Cron Script Does Not Run

Feb 21, 2011

I'm with Ubuntu server 10.10. I created a script and put it in /etc/cron.daily. But looks it doesn't run (it didn't generate any log). The following is all I did.
root@chonseng1:/var/log# cat /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab' command to install the new version when you edit this file and files in /etc/cron.d. These files also have username fields, that none of the other crontabs do.

CentOS 5 :: Emptied Cron.daily Accidently ?

Nov 25, 2010

I made a big rookie mistake in a script in cron.daily, which emptied the directory when I tested it... now I'm left with an empty cron.daily directory, and from what I know there definitely were more scripts there than only my own. Does anybody know what scripts CentOS 5.4 (Final) needs in the cron.daily?

Fedora :: Executable File Into The '/etc/cron.daily' Directory

Jan 19, 2011

I have noticed that in the /etc directory there are some subdirectories of /etc/cron.daily and /etc/cron.hourly. Also I have determined that there is a service included as part of the Fedora OS 'crond' which I have started with the use of 'service crond start'. My question is this. If I drop an executable file into the '/etc/cron.daily' directory will it just run? If not what configuration files should I go about editing to run my executable daily? There seems to be a pretty large network of cron related files. I'm trying to make sense out of all of it.

Ubuntu :: Archive Daily Images From Webcam-Server?

May 12, 2011

I was just wondering if there is a way (and seeing as how this is Linux we are talking about here, there probably is...) to make a fully functional webcam-server on Ubuntu 10.04.2 save images daily, or weekly? I have a perfectly installed webcam-server running on my website that you just refresh, and it gives you a current image, but I was wanting to have a daily type of archive thing with it, just because.

Ubuntu :: Do Cron Updates Erase Cron Entries

Sep 19, 2010

I put in my cron entries to run my backup script which rsyncs my data to my 2nd drive, however on a hunch I checked my backup drive which mounts automatically via fstab and I realize it had not ran in a while. I checked cron and there were no entries for it. I got to wondering if I should ever be worried about a cron update coming down and over-writing my existing cron file with the backup entries in it to run.

I want to make a cron job for my webserver, only it seems not to work...

I have now the followig to test (every 16th minute of the hour, write test to a file), but it doesn't show up. When I write out the cron, it is done to the file: /tmp/crontab.QXsBIO/crontab . How to make cron work? It must be very easy, but I have real troubles getting it fired up.

My Linux version is debian lenny and the cron file looks like (crontab -e):

Server :: Cron Job Not Working?

Jun 1, 2011

I have a cron job to run every 15 minutes. The cron job is running per /var/log/cron. It lists the job every 15 minutes.


I do not see any errors. I also looked in /var/log/messages for any errors and it does not list any. I added a line to the script that is running to send an email to me to see if it is running or not. When I run the script from the command line, the script runs without error and I get an email. I have searched and can not find what it going on. Is there some where else errors might be? Could there be a permission issue? The cron job is not being added by the root user.
