CentOS 5 Server :: Cron Job Doesn't Run, But Doesn't Error. "shutdown -r Now"
Aug 28, 2009Is 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 RelatedUbuntu :: Mp3blaster Doesn't Work With Cron
Mar 2, 2010I have a problem with mp3blaster.
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.

Server :: My Cron Job Doesn't Work
Jun 1, 2010I 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?

Ubuntu Servers :: Cron Will Not Run Rsync Job
Mar 30, 2011I 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:

Ubuntu Servers :: Cron Is Filling Up Logs?
Sep 1, 2011I 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)
