I've tried to get cron to run a script, but it does not work. At first I put it into /etc/cron.hourly, with no succsess. Then i added the line
Code:
To the crontab, with the same result.
I'm sure cron runs fine besides that Problem, because commands like
Get executed.
Is there something that blocks cron from running a shutdown command? I'm doing a daily bounce to break an attack (I have thread about that in security forum), but I always end up doing it manually. The cron log shows it being fired off at the right time...but the server never bounces. I thought maybe I just missed it, but there is nothing in messages that shows the server restarting (unlike when i do it manually, you see the start-up logging).
View 2 Replies View RelatedI have a simple cron job that runs every night & I tested this manually by just running the command as root in bash and all worked fine. It took some time but the crob job finished and I got my results emailed to me perfect / as expected.
Here is root's cron job listing:
Code:
Now I noticed that I never ever got anything emailed to me the following day so I am wondering if perhaps the Cron daemon doesn't have permissions or has an issue running / executing the command rather than when I test the command as 'root'? When I view my logs, I can see the command being executed and don't see any errors however I don't get email results when Cron runs the job rather than me taking the command and running it manually in Bash...then it works. What am I missing?

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 want cron to act as an alarm clock: first, it plays an mp3 file and then it runs the speech synthesizer festival which tells me to get up and do stuff.
Now, mp3blaster doesn't do anything when I run it from cron, but festival works without problems.
I've found some possible causes for mp3blaster not working through cron. Someone suggested that pulseaudio is not started. This shouldn't be the problem for me, since I don't even have pulseaudio installed, and festival is playing sound without problems...
I don't know what I should do to make it work.
Here is my script - runalarm.sh:
Code:
I don't want to include the wakeup text here since it contains profanity.
The mp3 player could be another one too. mp3blaster happens to be the only player I know that is easy to run from console, like this "mp3blaster goodsong.mp3", without and playlist creation or other stuff like that.
I can run the runalarm.sh from SSH console and it works fine, the mp3 starts playing and festival speaks after that. When run from cron, festival starts speaking right away and no mp3 is heard.
I'm trying to start a script through crond. The record in crontab is: 30 16 * * * /home/alex/razhodilim.pl 1>/dev/null. The script razhodilim.pl works perfectly if I start it manually. But cron fails to start it.
What could be the reason?

I created a very simple cron job for testing my first Linux system but It doesn't work.

The script does exist. And so does the directory /home/usr/log and writable. /var/log/syslog only has a bunch of these:

I don't see any file gets written to the log directory. That suggests to me that cron didn't run the job, as confirmed by /var/log/syslog.
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 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.)
It seems that cron is not upgrading my Ubuntu 8.04 LTS Server, no GUI installed. I changed /etc/crontab and watched apt running:
Code:
ps -A | grep apt
showed it for a long time,

sudo tcpdump tcp
showed communication with canonical sites,
but:
Code:

did not show any apt using CPU

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.
View 2 Replies View RelatedI have set up a cron in /var/spool/cron/root
*/15 * * * * /usr/bin/phplist.sh
I can see in /var/log/cron that it is running every 15 minutes but it has no effect. It is not doing the commands in the bash script.
If I run /usr/bin/phplist.sh right in the shell it works great.
Is my vixie-cron broken? i have "0-59 * * * * root /usr/sbin/logrotate /etc/logrotate.conf" but it is not running in /etc/cron.d.
Code:
I have a php script that checks versions of a remote stock file every 15 minutes. When it discovers that a new version is available it downloads the new file and runs it through a series of scripts that prepare it for an e-commerce application. It takes about an hour to import the file and process it. Otherwise, it echos "file on remote host not newer than local file". The stock file is updated every 3 or four hours and it's never at the same time. So we would like to run this script every 5, 10, or 15 minutes to make sure we have updated files.
So what happens when my php script finds a new file and takes an hour to do its work? Will the cron be activated three more times during this span? In other words, will it keep starting over even if its still running from a previous cron? Is there a way to stop the cron from running while the file download and processing occur, and then resume when its finished?
I have this script:
#!/bin/bash
## cifro un fichero
/usr/bin/gpg --encrypt --batch --no-tty --yes --recipient Mypubkey /home/joseba/salida.txt > /home/joseba/logcronjob.txt
#EOF
If I use the line
joseba@server$ /usr/bin/gpg --encrypt --batch --no-tty --yes --recipient Mypubkey /home/joseba/salida.txt > /home/joseba/logcronjob.txt
I dont have problems, salida.txt has encrypted
But by crontab -e (for user joseba) dont work and dont encrypt nothing If I use 'sudo crontab -e' same result, dont work
Mypubkey exists
On logcronjob.txt nothing, 0 bytes I think env its ok for the users

View 5 Replies View RelatedHow can one have commands in cron? I do not know much but do know that there is something called cron. I read the manpage[quote=Cron Debian Man page]cron - daemon to execute scheduled commands (Vixie Cron)[/quote] and it says to make files in /var/spool/cron/crontabsWhile I went to /var/spool/cron/crontabs I did not find anything there. I just want to tell cron that it runs $sudo aptitude autoclean at some time in the background. Is this possible? If yes, then how ?

why my second cron job isn't running? The first one runs fine but the second one does not run at all. If I manually run the script using ./check.sh then it does what it is supposed to but will not run from cron. It should run every weekday at 9:45am, it looks good to me but clearly I am doing something wrong.
Code:
# m h dom mon dow command
#This will backup my hosted websites.

#This will run check and upload it's contents to the net.

Cron refuses to work for a newbie.I am trying to setup a cron job to backup a folder in my home directory ('/home/scratch') to a folder ('home/internet_backup') that is mounted (using nfs) to a network folder.the folder ('home/internet_backup') is mounted correctly to the network folder upon system startup, so this part works.
