I'm trying to remotely schedule a shutdown using cron but I can't get it to work. I did setup the following 'sudo crontab -e'
Code:
For some reason doesn't this work, since I was able to login and get this output when using 'date'
Code:
Have a headless server running Lucid 64 bit. Everything is working great except for a couple of Cron jos I'm trying to have run at boot.
My user crontab looks like this:
# m h dom mon dow command
01 * * * * /home/ceallred/Scripts/SambaBkup.sh
@reboot /usr/bin/SpiderOak --headless &The SambaBkup script works like clockwork...
The SpiderOak job doesn't start. It works if I type the command in manually.
syslog only shows:Jul 13 22:45:33 RavenWing cron[1010]: (CRON) INFO (pidfile fd = 3)
Jul 13 22:45:33 RavenWing cron[1022]: (CRON) STARTUP (fork ok)

Can anyone tell me how i change the default domain name for cron?everything i cron runs it emails from and to user@com.com
this leaves me with a massive list of failed mails in postfix.i have mailto on my main crontab but i cant do it on all of them.
I have this symlinked into my /etc/cron.d folder:
Code:
*/5 * * * * python /srv/bidsite/manage.py send_mail
* * * * * echo `date` >> /home/bidsite/what.txt
but it does nothing. What I really want to happen is the first line. The second line is just for testing.
After I create a cron job to shred some documents it seems to start and then immediately stop. What am I doing wrong? For instance, here is my cron:

I'm not sure exactly which version it was, but it was the most recent version a month ago. I ran the uninstaller which ships with webmin.Well, now everyday my root account gets the following email:

I am running a headless Ubuntu server accessed through Webmin. The server is running 10.4.2 64 bit version. I have a number of cron jobs including a simple back-up job which is:
Code:
rsync -av /media/server/ /media/backup/backup/
All of the other jobs run fine but for some reason this job which is scheduled to run each day at midnight does not run. If I SSH into the server and run the job manually it works fine.
The output of 'crontab -l' is:
@daily rsync -av /media/server/ /media/backup/backup/

I am unable to run my cron tab job without root password.I made a little research on the forums and appearantly it should be changed.Must I change "passwd" part with my root password?

I am using my ubuntu server as my home router.Everything is working as expected with one exception.y DSL modem is a POS and every now and again it looses connection to the router. Sometimes it needs to be reset and sometimes it does not.Either way, when this happens my ubuntu server needs to reacquire an IP from my ISP. If it screws up when I'm at home it's no big deal, but if it happens when I'm not around my housemates have taken to hitting the reset switch on the server. I'm not a big fan of this so I wrote a script to ping my ISP's gateway. If it's unavailable it bounces the eth0 interface and tries to get an IP. I am running this script every couple of minutes in a cron job. Now I'm getting syslog entries like
Code:
Aug 9 20:31:01 portal CRON[9602]: (root) CMD (/opt/ChkAndFixNetwork.sh)
every few minutes. This is annoying and makes the logs useless for troubleshooting. I

So far I found when I use corn following part not working, nothing goes to the processedfiles file. ls -l /var/lct/mou2/processed | grep $TODAY | awk '{print " " $8}' > /home/trans/mou/processedfiles ls -l /var/lct/mou2/processed | grep $YESTERDAY | awk '{print " " $8}' >> /home/trans/mou/processedfiles This work perfect in command line. Corn job and command line use by the same user.
I've read a lot on how to setup a task in crontab. I think I understand how to edit the file, but when I try to save the changes, it says "no crontab for xxx." Then it says that it cannot create a new crontab. I have ubuntu desktop 9 running as a webserver. I've read the details in these posts and it isn't helping.

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.

My backup script works fine after some effort to get it where I wanted it. So the script is fine when I run it.
sudo bash backup.sh
now I have a sym-link to /etc/cron.daily but I do not see any new backups
Code:
#!/bin/sh
chown -Rc steven:users "/home/steven"
I have more lines in the script but each line does the same error. This is run in a cron job but it always returns.
Code:
chown: cannot access `/home/steven

But it is a valid directory I have even tried adding an / and even a space on the end and still same error.
I recently set up exim so that I could test emails sent from my php sites. I have now been getting daily emails that either report errors from cron jobs or report a failure to send emails to root@cory-laptop or cory@cory-laptop about cron errors.I first of all don't want mail sent to the above addresses, because they are obviously not actual email addresses. Second, I'd really prefer not to get emails when an email failed to send to these addresses.

I am running a series of operations on executable matlab scripts which are connecting python and fortran scripts. I schedule the executables in cron. The problem:
- My original matlab scripts work perfectly.
- My executables work perfectly if I run them from the terminal. - Using the gui scheduled tasks and running the scripts once from a button, everything also works fine.
- But when I leave the scheduled tasks run on their own, I get an error! The error can be that the script hangs in general (I have some text logs exported every step to track the progress), or I get an error which never appears when I run the script with any of the other mentioned ways.
- I tried both cron command prompt or the GUI scheduled tasks
- I am running on Ubuntu 64 bit
I'm getting the following messages sent to my root account mailbox. It appears to be reporting an issue finding ntpdate, however when running the following command:
aptitude show ntpdate | grep State
It shows as installed and any ntpdate commands work with no issues, so I have no idea why this is getting regularly reported?

I made a Bash script that is fired by a Cron job every morning. It dumps an SVN backup on some Samba shared drive. I would like to know how I can make sure the job worked correctly without having to verify the shared drive every morning. Right now, I take the job's output, save it to a log file and send this file by email. But the ouput isn't so great.

I'm running a cron job every night to dump a MySQL database to an external hard drive. It works, however when I check on it the following morning the external is no longer mounted and the XFS log file is corrupted. If I run
Code:
xfs_repair -L /dev/sdf1
It works, but then I get these issues:
Code:
XFS: Filesystem sdf1 has duplicate UUID - can't mount
I can reset the UUID, but it's difficult to have to do this every day.
I have a ts3.desktop file in my /usr/share/applications folder that I want to run on system boot. I have typed the following commands which don't work
Code: Select allcrontab -e
Then in the editor, I typed the following line at the bottom of file. I also made the necessary carriage return after this line.
Code: Select all@reboot gtk-launch ts3 /usr/share/applications
Then I pressed ctrl+o to save it.
After I put these commands in, I did the following command to troubleshooting this issue, see below.
Code: Select all$ crontab -l

$ps -ef | grep cron | grep -v grep

I'm running cygwin 1.7 on a vanilla win2k3 r2 server. I've put together a simple crontab that I'll paste in her in a sec. The crontab entries call several shell scripts that do either scp's or rsync's from linux servers to this win2k3 box under cygwin.
The problem is that the scripts work and run fine from the commandline. Just not when called from the crontab. I'm running from the root equivalent administrator UID. The crontab log files are empty of errors.

Like I said, the scripts execute fine from the command line.
