When I setup crontab as a local user (settings shown below), then it can pop-up a xmessage windows * * * * * DISPLAY=:0.0 /usr/bin/xmessage -center "warning message here" but when I switch to root, and setup the same things in crontab, why it cannot pop-up a xmessage windows? Any special limitation for root to use crontab?

I've just discovered that crontab is creating a new file in the root directory every time it executes a cronjob, and it doesn't erase over the old file so there are thousands of files in the root directory, they have the same name as the script file (appended with a numeral) but are all blank.here is what one of the cronjob's looks like[URL]
View 10 Replies View RelatedI 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 can use Ubuntu from my flash drive, but I want to install it in a partition alongside windows. When I try to do this, I come to an 'allocate drive space' window, but whatever I do I get the error message: 'No root file system is defined. Please correct this from the partitioning menu.' I just don't know what this means, or what to do next. I'm loathe to ditch windows, and I don't want to have to use a flashdrive all the time.

I have been having trouble setting up a daily backup script with cron. It would basically never worked. Searched the net for answers but didn't find anything. I finally figured it out !! When root crontab is edited the execute flag is removed from #/var/spool/cron/crontabs/root. I change it with #chmod a+x /var/spool/cron/crontabs/root and all is good.

View 2 Replies View RelatedI'm trying to install CentOS 5.5 on an old Pentium 4 desktop PC I have, which is not being used for much other than being a MTA, and I want to migrate this functionality onto the CentOS platform for stability (Windows is a perpetual nightmare. I partitioned a spare 20GB to experiment with, and I want to install CentOS into here to play around with first so I can move my files around between Windows and CentOS, until I'm happy all of the stuff is gone, then I can scrub the Windows partition and claim the space for CentOS.
So, I've downloaded and burned the DVD and tried to install. I start the install with no args from the main install menu, and the process goes through some probing and then comes up with the "Welcome to CentOS" menu. I go through this, and then it tries to start X Server. It fails, and falls back to text mode. I get the "Welcome to CentOS" screen again, and then proceed through it. I set my keyboard layout to UK, then this message comes up at the bottom of the screen:
"_X11TransSocketINETConnect() can't get address for localhost:6001: Temporary failure in name resolution"
then on the next line: "Cannot open display :1" If I force the install to text, by typing "linux text" at the first menu, I get about the same way through, but the install just hangs doing nothing, and no disc access to the install disc.
I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?
