Ubuntu Servers :: Cannot Find A Particular Cron Job?
Oct 25, 2010
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
Return-Path: <root@DOMAIN.com>
Date: Mon, 18 Oct 2010 00:42:01 -0400
Cron for root does not run,it's 8.04LTS ubuntu server,however Cron runs for other users,Can anyone help?i've checked many times that i have the right syntax.
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.
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'm trying to setup a cron with screen. the purpose of running screen is because i want to resume to see the status of the job while it is running. anyone can enlighten me how i should setup my cron. I've tested with
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

I 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) every few minutes. This is annoying and makes the logs useless for troubleshooting. I
Have a headless server running Lucid 64 bit. Everything is working great except for a couple of Cron jos I'm trying to have run at boot.
My user crontab looks like this: # m h dom mon dow command 01 * * * * /home/ceallred/Scripts/SambaBkup.sh @reboot /usr/bin/SpiderOak --headless &The SambaBkup script works like clockwork...
The SpiderOak job doesn't start. It works if I type the command in manually. syslog only shows:Jul 13 22:45:33 RavenWing cron[1010]: (CRON) INFO (pidfile fd = 3) Jul 13 22:45:33 RavenWing cron[1022]: (CRON) STARTUP (fork ok) Jul 13 22:45:33 RavenWing cron[1022]: (CRON) INFO (Running @reboot jobs) Jul 13 22:45:33 RavenWing CRON[1048]: (ceallred) CMD (/usr/bin/SpiderOak --headless &)Yet ps -A doesn't show a running SpiderOak process. It shows after starting manually.
Code: #!/bin/sh chown -Rc steven:users "/home/steven" I have more lines in the script but each line does the same error. This is run in a cron job but it always returns.
Code: chown: cannot access `/home/steven ': No such file or directory But it is a valid directory I have even tried adding an / and even a space on the end and still same error.
I recently set up exim so that I could test emails sent from my php sites. I have now been getting daily emails that either report errors from cron jobs or report a failure to send emails to root@cory-laptop or cory@cory-laptop about cron errors.I first of all don't want mail sent to the above addresses, because they are obviously not actual email addresses. Second, I'd really prefer not to get emails when an email failed to send to these addresses.
I'm getting the following messages sent to my root account mailbox. It appears to be reporting an issue finding ntpdate, however when running the following command:
aptitude show ntpdate | grep State
It shows as installed and any ntpdate commands work with no issues, so I have no idea why this is getting regularly reported?

I wrote/cobbled-together this nifty sendmail script to read some logs and take some disk stats. basically i'm reporting on rsnapshot. When I run it as
Code: sudo /etc/rsnapshot/mailSta.sh Everything works wonderful and the emails arrive as expected and fires off an email to two accounts at a remote server
I made a Bash script that is fired by a Cron job every morning. It dumps an SVN backup on some Samba shared drive. I would like to know how I can make sure the job worked correctly without having to verify the shared drive every morning. Right now, I take the job's output, save it to a log file and send this file by email. But the ouput isn't so great.
I'm running a cron job every night to dump a MySQL database to an external hard drive. It works, however when I check on it the following morning the external is no longer mounted and the XFS log file is corrupted. If I run
Code: xfs_repair -L /dev/sdf1 It works, but then I get these issues: Code: XFS: Filesystem sdf1 has duplicate UUID - can't mount I can reset the UUID, but it's difficult to have to do this every day.
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.
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.)
I have an Ubuntu 11.04 server with lighttpd installed as my web server. It was working fine, but now when I restart it it gives me the following error...
"can't bind to port: 80 Address already in use"
Is there a way for me to find out what is using port 80 in it's place?
Having had an old machine running SMEServer for some time, I've decided it doesn't suit my needs and I've gone the Ubuntu Server 10.04 root. I'm having trouble connecting to a HP LaserJet 5P attached to the parallel port of the server. I had no trouble connecting to it when the server was running SMEServer, however, as this distro is aimed at Windows clients, the printer was configured as a Samba share.
In the new 10.04 configuration, I do not have Samba installed as I have no need for it. I'm exclusively Linux based (Ubuntu 10.04 desktop). Surely I do not have to install Samba in order to print?
Where to find SSH Server Configuration Howto for Dummies? To Ubuntu 10.04 LTS Server? Must work like FTP/SFTP and user accounts must be in MySQL. Just for File Transfer and user can open only his / her own ./ where is public_html in root..
I have Ubuntu 10.04 Server running on an old pc in my basement. I installed samba and samba4 on it. I added users, etc. However, i cannot find it in my network locations on my Ubuntu 10.10 laptop
