Ubuntu Servers :: 10.10 - Daily Cron Script Does Not Run

Feb 21, 2011

I'm with Ubuntu server 10.10. I created a script and put it in /etc/cron.daily. But looks it doesn't run (it didn't generate any log). The following is all I did.
Code:
root@chonseng1:/var/log# cat /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab' command to install the new version when you edit this file and files in /etc/cron.d. These files also have username fields, that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user command
17 * * * * root cd / && run-parts --report /etc/cron.hourly
25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#
root@chonseng1:/var/log# ls -l /etc/cron.daily/ntpdate
-rwxr-xr-x 1 root root 52 2011-02-18 13:22 /etc/cron.daily/ntpdate

Debian Configuration :: Cron.daily Not Running Daily On Laptop?

May 31, 2011

I am running on a laptop and cron.daily is set to run at 0625 So I wonder what happens if my machine is not turned on at that time.. At that rate it could also be off for the other periods as well (weekly, monthly) Is there solution that will allow them to run once they are online after the appointed time? using a cron entry that runs every 15 or 5 or 1 minute.

Fedora :: No Output From Cron Jobs In /etc/cron.daily

Jan 29, 2011

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.)

CentOS 5 :: No Items From /etc/cron.daily Run On 5.3

Oct 26, 2009

I'm having a very strange issue with cron on centos 5.3 64-bit. I have 3 cron scripts in /etc/cron.daily which run backups. They are as follows:

script1:

#!/bin/bash
/usr/local/bin/backup-script1

script2:

#!/bin/bash
/usr/local/bin/backup-script2

script3:

#!/bin/bash
/usr/local/bin/backup-script3

The contents of the 3 /usr/local/bin scripts are ...

/usr/local/bin/backup-script1:
#!/bin/bash
synbak -s srv1 -m rsync
rsync -av --delete /data/backup/srv1/* root@::share/srv1/

To explain this, the 1st active line does a synbak backup and the 2nd active line rsyncs the backup data to a remote server.

/usr/local/bin/backup-script2:
#!/bin/bash
synbak -s srv2 -m rsync
rsync -av --delete /data/backup/srv2/* root@::share/srv2/

[code]....

CentOS 5 :: Emptied Cron.daily Accidently ?

Nov 25, 2010

I made a big rookie mistake in a script in cron.daily, which emptied the directory when I tested it... now I'm left with an empty cron.daily directory, and from what I know there definitely were more scripts there than only my own. Does anybody know what scripts CentOS 5.4 (Final) needs in the cron.daily?

Fedora :: Executable File Into The '/etc/cron.daily' Directory

Jan 19, 2011

I have noticed that in the /etc directory there are some subdirectories of /etc/cron.daily and /etc/cron.hourly. Also I have determined that there is a service included as part of the Fedora OS 'crond' which I have started with the use of 'service crond start'. My question is this. If I drop an executable file into the '/etc/cron.daily' directory will it just run? If not what configuration files should I go about editing to run my executable daily? There seems to be a pretty large network of cron related files. I'm trying to make sense out of all of it.

Ubuntu :: Scp From Shell Script Using Cron

Oct 12, 2010

I have a script that I would like to run using 'cron'. I want to use 'scp' to transfer files from one machine to another. I have set up the SSH keys on both machines. When I run the script from bash terminal, it works flawlessly. But when I schedule a 'cron' job to run the same script, 'scp' does not transfer the files.

'Return value' is 0 when the script is run from bash directly. But when it runs from 'cron', the 'Return value' is 1. That means, surely, that 'scp' is throwing an error. I don't know which error is being encountered. Could anybody let me know how to make it work?

Red Hat :: Servers Don't Send Out A Daily Logwatch Email?

May 9, 2010

Gidday, for some reason some of my RHEL servers don't send out a daily logwatch email (most do, but two don't) - and sadly I have no idea how to troubleshoot this.

Can anybody give some help/hints as to where/how I may troubleshoot this. I should add that these servers can/do send emails (I have some cronjobs that fire off emails upon completion of their jobs, so I know its not a sendmail config issue).

Fedora Servers :: FC8 Dell Poweredge Crashes Almost Daily?

Jan 5, 2009

I have a Dell Poweredge, 6 months old, running Fedora core 8. I have 2GB RAM and 500Gb SATA HD. I am running 3 VMWare machines. Two Win2003 Servers and 1 XP Pro. My server crashes almost daily. It doesn't actually reboot, it just freezes. It got to the point where I had to get a device that automatically reboots the server when it can't ping the server anymore. /var/log/messages has no entries that indicates the server crashed. It just stops at the point where it dies. The windows VMWare server also have no errors in the event log to indicate a problem.

Ubuntu :: Cron Runs Shell Script - But Only First Line Of It?

May 18, 2010

I have a cron job that runs a shell script. But it only runs the first line of that shell script and not the rest of the file. I'm a little stumped as to why. If I run the shell script manually, it runs and executes every single line as it should. I think I must need some additional syntax to make this run correctly?

Here is the crontab ...

Code:
root@kchlinux:~/macs# crontab -l
# m h dom mon dow command

Ubuntu :: Timestamp Format - Shell Versus Cron Job

Jun 16, 2010

Setup: 10.04 server with "bash" as /bin/sh
When I run "ls -l" in a shell I get the following format:

Code:
-rw-r----- 1 syslog adm 0 2010-06-13 06:53 /var/log/user.log
Whereas if "ls -l" executes from a cron job the format is:

Code:
-rw-r----- 1 syslog adm 0 Jun 13 06:53 /var/log/user.log
Notice the different time format. Now I could fix this by changing the cron job to

Code:
ls -l --time-style=+%Y-%m-%d %H:%M ...
but I'm interested in knowing why this behavior occurs. What's different between the cron job and the shell?

Ubuntu :: Creating Shell Script From Source Code For Cron?

Jan 31, 2010

This is regarding the KDE application Basket:

I want to create a shell script that I can run as a cron job to do automated backups. how to proceed. I have the source code and have pulled out the backup source files. Here is the link for the source code. The download is at the bottom of this page. The backup files can be found in the src folder listed as backup.cpp and backup.h [URL]

If someone can do this, I believe it will make a nice addition to the Basket application for all.

Also I am not running Kubuntu I am running Karmic 9.10 64 bit

General :: Running Shell Scripts With Cron

Sep 24, 2009

I've been having a bit of trouble running a shell script with cron. A friend of mine does a community radio show and the station has a live stream but no podcasts, so I've set up a script to record the stream and encode it as an mp3 while I'm away using mplayer and lame -that's what I'm trying to do anyway.

Here's the script, but it doesn't seem to run- at least, I don't see any of the files it should be outputing, would they be in the cron.weekly directory (where I have the script) or in my home directory?

#This is a script to record 'The Unnamed Show'

#it will record the show from the live stream, then convert the output #to an MP3

#Finally, it will delete any files no longer required HOME=/home/byron/

Software :: Running A Shell Script From Cron ?

Jul 1, 2010

Im having some difficulties with running a shell script from cron which I am unable to resolve for almost 2 days now.

For testing purposes, im trying this with simple shell script test.sh with chmod 777

This script is located at /var
When I type /var/test.sh it runs perfectly and prints asdasdasd
When I type /var/test.sh > /home/log it writes asdasdasd to /home/log - works

The problem occurs whenever I add it as a cron job to var/spool/cron/crontab/root

There is: 11 10 * * * /var/test.sh > /home/log - however, at 10:11 there is no file at /home/log

Cron as a service works, forexample, every day at 4 am it makes this backup sshpass -p xxxx rsync -avz -e ssh root@x.x.10.7:/data/backup/ /home/backups/isp_admin

However,

doesnt makes the folder

Where is the catch?

Ubuntu :: Script Fails In Cron But Runs Fine In Regular Shell?

Ubuntu Servers :: Cannot Find A Particular Cron Job?

Ubuntu server 10.04:I had webmin installed on my server, but I found it was using too many resources for what it offered, so I went ahead and uninstalled it. 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:

From root@DOMAIN.com Mon Oct 18 00:42:01 2010

Ubuntu Servers :: Cron Will Not Run Rsync Job

Mar 30, 2011

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/
11 3 * * * /etc/webmin/package-updates/update.pl
@daily tar czf /media/backup/serversystem.bz2 --exclude=/proc --exclude=/lost+found --exclude=/backup.tar.bz2 --exclude=/mnt --exclude=/media --exclude=/sys /
@reboot inadyn --username ********** --password ********** --update_period_sec 600 --alias **********
@daily /etc/webmin/backup-config/backup.pl 12978522112842

The output of 'crontab -e' is:
Error opening terminal: unknown.
crontab: "/usr/bin/sensible-editor" exited with status 1
