View 4 Replies View RelatedUbuntu Servers :: After Using Crontab With /etc/crontab / Giving Error "can't Find Command Root"?
Aug 26, 2010I have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)

Ubuntu :: Schedule A GUI App With At Or Crontab?
Mar 2, 2010I want to schedule a Java program to run at a certain time, which will open a GUI progress monitor while it runs, and then terminate when it's done. I can execute it fine from the command line, but I it doesn't seem to work when I schedule it with crontab. In fact, I can't make any gui by scheduling it, not even something like gedit or firefox.
I know it's pretty rare that someone would want to do this, but is there any way to schedule a GUI app?
Ubuntu :: How To Restart Gdm From Crontab
Jun 16, 2010I'm having problems trying to restart gdm from crontab and I'm not sure what I'm doing wrong. Basically what I want to do is a 'logout' every morning before I get to work so that by the time I get to my computer I would just have to log back in and have a fresh gnome session.
The command I'm using to restart gdm is:
Code:
/usr/sbin/service gdm restart
If I run this command from a terminal as root it works.
To edit my crontab file I'm doing:
Code:
sudo crontab -u root -e
And adding the following line to it:
Code:
25 08 * * 1-5 /usr/sbin/service gdm restart
My understanding is that this should restart gdm every day of the work week (Mon-Fri) at 08:25. But for some reason this is not happening.
I also checked that my cron deamon is running by:
Code:
~$ service gdm status
gdm start/running, process 27156

Ubuntu :: Rsync - .sh And Crontab
Feb 14, 2011I'm currently trying to have crontab to automatically backup files from ramdisk. It works perfectly when I run it myself by simply cd:ing to scripts directory and type ./save_world.sh.
The problem is, that crontab DOES (at least it looks like it) run that command every one minute. /var/log/syslog does show it executing that line every one minute without any errors. I'm currently very confused what I did wrong here. I have tried rebooting, fiddling with crontab line, tried sudo crontab -e but nothing seems to work.
My script is called save_world.sh and it is located in /home/phoe/minecraft/rpg/

Ubuntu :: Using Crontab To Restart Pidgin?
May 23, 2010Pidgin likes to randomly crash on me, and sometimes it takes me awhile to notice. So I thought why not make a script and cron job to see if pidgin is running and restart it if needed. Sounded easy but having all kinds of problems. Here's my cron line...
Code:
*/1 * * * * /home/justin/chkpdgn.sh >> /home/justin/test.log 2>&1
I run "tail -f /home/justin/test.log" to keep an eye on the cron output.
Here's the chkpdgn.sh script...
Code:
#!/bin/bash
SERVICE='pidgin'
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
echo "$SERVICE is not running"
$SERVICE
fi
Running that works fine when I do it, but when cron does it pidgin never starts and I get this error...
Code:
pidgin is not running
error: line 15: bad flag alias index: 0
error: line 15: bad flag vector alias
error: line 16: bad flag alias index: 0
error: line 16: bad flag vector alias
That goes on for quite awhile up to like line 60000 and pidgin runs but doesn't show up in the me menu. Any way to restart pidgin when it crashes?
Ubuntu :: Making Script To Be Run With Crontab
Jun 29, 2010Not strictly being applied to an Ubuntu distro but Linux all the same.Our company run a database server referenced by a number of mail servers; the database server is very soon to be replaced since it's old, decrepit and not as secure as it should be - indeed, when it decides it's had enough, the MySQL process will simply stop.You can restart MySQL if you need to quite easily; using Putty, I'll connect to the box and run the command:/etc/rc.d/ init.d/mysqld restart
Using /etc/rc.d/init.d/mysqld status you can get a response of either mysqld (pid 8354) is running... or mysqld is stopped - how can I use this information in a script so that mysqld is only restarted if every thirty minutes a check comes back to say it's stopped? this current server is replaced by someone who knows what he's doing in a few weeks but this will ensure less disruption to those who rely on the current incarnation...

Ubuntu :: 10.04 - Crontab And Daylight Savings?
Nov 12, 2010I recently set up some new cron jobs under Ubuntu 10.04 64-bit (all the latest patches as of Nov. 11th) and just happened to check right after one was supposed to run and it hadn't run yet. Checking the logs I found the previous cron job ran exactly one hour later than it was supposed to. Is there something going on with Ubuntu 10.04, cron, and daylight savings where cron pretends daylight savings never happened or something?

Ubuntu :: Crontab - None Of Job Apparently Running

Code:
# crontab -l
# m h dom mon dow command
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/managed_arp_data.pl >> /var/log/arpdb.log
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_fixed_sync.pl >> /var/log/crossref.log

0 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_excl_sync.pl >> /var/log/excl_sync.log
None of these jobs is apparently running, however they did run on the 31st (yesterday), but not on the 30th or any other day during the last 10 days that I have logs for. I think I've set cron to run at log level 1, but I don't know where that log goes, I don't see anything like /var/log/cron
So, couple questions:
* If I do something like "sudo -s" to get a root prompt and then do a "crontab -e", which user does that crontab get executed as?
* Where should I look for cron logs?
* Anyone know why a job would run on the 31st, but not any other day?
Ubuntu :: Does Anyone Know Good Gui / Frontend For Crontab?

As far as I can tell a good one doesn't exist anymore.kcron - what I used to use, no longer exists (and I switched to ubuntu from kubuntu)gnome-schedule - does not show all users, does not allow for fine control that kcron had.Does anyone know a good gui/frontend for crontab? I guess I'm just going to have to get in the habit of researching the file syntax, how to edit it, and editing manually.

View 2 Replies View RelatedUbuntu Security :: Crontab Disabling Internet From 7pm To 7am?
Apr 11, 2010I administer a desktop computer with ubuntu 8.04 in an university library. Since it works almost all night, to enable students to study, after some time I noticed some misuses of the computer during the evening, when there isn't many students. My goal was to disable users from accessing internet from 7pm to 7am, but also enable it if certain user was logged in (I use that user for torrent, and I seed on that computers from time to time). So I created a script that's being called by root's crontab, and here is the script's code:
Code:
#!/bin/bash
NUM=`who|grep myuser|wc -l`
#echo $NUM
if [ $NUM -le 0 ]; then
/sbin/ifconfig eth0 down
else
/sbin/ifconfig eth0 up
fi
Since I created the script, I actually never seeded anything, so I'm wondering now if that's going to work at all, and (also) is there a better solution for this.
