Ubuntu Servers :: Crontab Not Running Script?
Jan 27, 2011
Cron seems to be running the script below (According to /var/log/syslog) but I'm not receiving the email it should send. This does work when I invoke it manually. checkraid (-rwxr-xr-x 1 root root)
Code:
#!/bin/bash
echo `/sbin/dmraid -s > /etc/check-raid/check_state`
index=0
while read line; do

I 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)

I am using Linux 64 bit Redhat Linux. I am trying to setup simple crontab as follow...1. Edited crontab file using crontab -e2. Listed the file once to verify it using crontab -l.

Code...
I opened "crontab -e" in the Terminal and in nano I copied and pasted the first line of this copied script, leaving all the notated lines out. Each time I manually run changer by clicking and selecting "Run" it changes my Wallpaper but this does not happen automatically no matter how many times I reboot.

I have the following set up in my crontab:
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
00 23 * * * /usr/bin/perl /usr/local/bin/perl/infoblox_host_sync.pl >> /var/log/host_sync.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?

Both of these files are owned by root, is it a permissions thing? How can I get get cron to run the files?

I'm using crontab to start and stop music playback (its like start and end of a brake in school). The problem is that some of the entries should be run on even weeks and some on odd.
exp:
This should be played on even weeks
00 08 * * * audacious -p
10 08 * * * audacious -u
and this on odd
05 08 * * * audacious -p
15 08 * * * audacious -u
There are about 20 entries for even and 20 for odd. I found here on the forum that maybe this should work but for it is not working for me
00 08 * * * [[ $(expr `date +\%W` \% 2) = 0 ]] && audacious -p
If I put it like that its not working at all

I am planning on running a script once every five minutes, and the syntax that comes to mind in doing this is the following:
Code:
5 10 15 20 25 30 35 40 45 50 55 * * * * /apps/<script>.pl
Is there a better syntax to use to accomplish this task, or is the above example the way to go?

Yes I have tried exporting my paths and variables aab still will not run my script. 'm sure I am doing something wrong.I have a shell script which runs a jar file. This is not working correctly. After reading around I have read this is commonly due to incorrect paths due to cron running via it's own shell instance and therefore does not have the same preferences setup as my profile does.here is what my script looks like today after several modifications:
Code:
#!/bin/bash --
. /root/.bash_profile

I have a shell script which is configured for the user. The main task of the shell script is to email certain user with a particular result.
The shell script runs perfectly when run from a Konsole terminal and configured through a crontab generates empty entries.
Below is my crontab for my user.
Code:
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.XXXXSyNyp1 installed on Wed Jan 6 09:14:14 2010)
# (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)

I have been searching for a few hours now trying to figure out the best way to have Ubuntu Server 8.10 copy and replace a file every week.
So for example:
File A (original file)
File B (replacement file)
I would want to copy File B from its location and replace File A each week automatically with out removing or destroying File B.
I've thought of doing a cron since I already have a job set for email piping. but I'm unsure of the best way to complete this task.

As root, I use crontab to run mirrordir to backup directories. Everything gets copied over properly, but owner information isn't preserved and root is the owner of all the backed up files. I can deal with that, but crontab reports tons and tons of chown/chgrp errors for mirrordir every time I do back ups--which is every day--and the multiple emails to root of thousands of chown/chgrp errors is very annoying. The error is "Operation not permitted," but that doesn't make sense to me because the job runs as root (right?) and clearly the job is permitted to create the backup files, so why would it fail to chown and chgrp?
I've had the exact same setup on another server for years, and crontab has always run mirrordir without error. Any suggestions how to clear the errors on my new server?

We are running IPmonitor to monitor the disk usage on our Linux servers. It does not seem to coincide with what is reported when running df -h. For example on a Red Hat 5.3 server - our IPmonitor shows that 85% is used on the /usr partition, however when I do a df -h on the server it shows that 91% is used. Why there would be a discrepancy? IPmonitor uses SNMP.

I am running ubuntu 10.04 as a web/file server. I have set up several cron jobs in the past which until recently were executing normally. However, a few days ago, cron jobs stopped executing after a restart. I was able to fix the problem by deleting and reentering the cron jobs, but only until the next restart. ps -ef lists cron.
Summary:
1.) Cron was working --jobs executed without error and restarts worked fine
2.) Cron jobs stopped executing after a restart about a week ago --ps -e still lists cron
3.) Removing all cron jobs and reentering them by copying and pasting fixes until next restart
4.) Cron job syntax is known to be correct since they were executing before this problem arose.

I am running apache2 and tornado web servers on the same server with one ip address.
The apache2 listens on port 80. Tornado listens on port 8888. I want to redirect requests from a specific ip port 80 to port 8888. I don't have the ability to change the port request on the device. It wants is looking for a web server on port 80.
Any other web server request should go to the apache.
I tried adding the following to /etc/ufw/before.rules
When I run iptables -L it doesn't appear. I have disabled and enabled ufw with no help.
