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.

This will display as.. 18 5 * * 2-3 ksh $HOME/testScript.sh > $HOME/testscript.out3. Logged in a root and restarted cron deamon using "/etc/init.d/crond restart"As per my understanding now my testScript should start running at 5:18 am Thuesday

View 2 Replies View RelatedI had my BIOS complaing that there were no OS. (worked since releaseday of 11.2).
partition setup:
sda1 : primary : swap
sda2 : primary : ext3 : Kubuntu
sda3 : primary : ext3 : opensuse (flagged as bootable)
sda5 : logical
sda6 : logical
opensuses GRUB is primary and Kubuntus is chainloaded.
The problem occurred after I tried to boot kubuntu for the first time since I installed opensuse. Kubuntu didn't boot. so I probably set up chainloading wrong. No big deal, this I can fix.
The big problem was that after trying to boot Kubuntu no OS was marked as "Boot" in MBR. This is VERY strange. somehow the boot-flag is removed!
After setting the boot-flag (with a live-CD) everything works again. I can reproduce this.
I've tried to find answers but could'nt find any.
Is GRUB supposed to remove the boot-flag when chainloading? have I found a bug?
We have started using ACLs on our fileserver and we are having a problem with getting Samba to behave correctly. When we create a file in Linux, the permissions and ACLs are set correctly. Files are set to 640 and directories are set to 750. However, when we create it in Windows through Samba, regular files are being set with 650 and directories are set to 770. It's adding execute on files and execute+write to directories for groups.

View 8 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 have and entry in a crontab for my user (appadmin) that when it executes it does not start with the proper path. It needs to start as the appadmin user as appadmin owns all the directories for glassfish. However, once glassfish restarts, the hudson application cannot find the default JDK. I get an error. If I initiate the restart via command line, all works as it should. I believe it has something to do with PATH in the crontab but am not sure what I need to set the PATH to in crontab.

I've recently been trying to restore a Debian installation back to it's previous state after a serious operation system crash. Efforts are largely going well however I've run into problems since reinstalling Wine. Previously I could execute a Windows executable by simply entering ./executable.exe in the bash shell but this no longer seems to work as now I have to include the "wine" command in front of the executable. how to configure Debian to automatically use Wine to execute using the ./executable.exe format?

View 2 Replies View RelatedI 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 have set up my crontab and whilst Im logged in and it works (It runs my shell script), however when Im not logged in, the script does not run. Initially I set the time/date to 0 0 * * * (Midnight every day), as this did not work, I tested it with to 0 * * * * (every hour) whilst logged in and the script starts.
I use crontab -e to set it up under the root account..Im sure you dont have to be logged in for it to run?, but maybe im missing a step or just overdosing on Linux and need a holiday:-)

I have a "time-server". It's sending time to different devices through different ports/protocols. The problem is that it has no operator and that makes some extra difficulties.
Now when i try to start it using terminal Code: Select allsudo ./myprogram works fine and
Code: Select all./myprogram doesn't work.
It is so because without sudo i have no access to ports. As a result If i add my program to System->Preferences->Startup Applications it has the same problem. So i need to start it as root, auto-start, right after auto-login to system but without entering password cause nobody will do it.
Also I need to start ntpd but it also asks password sometimes I've tried googles but it offer a few ways with entering password that isn't suitable for me or writing some scripts/changing system files but with no example I'm afraid to break it all. So is there a way to start Myprogram and NTPD as root with no password entering?

For my dissertation I created a debootstrap install of Lenny. When I boot this system I just can login with root without a password. When I want to ssh this machine with the debootstrap install I can't just login with root. I'm asked for a password which I don't have.
So I created one with passwd root and after that I can connect to the machine with ssh and the given password. But the machine still logs in with without a password.
I'm configuring some security and i'd like to run arpon to a specific device everytime wicd connects.So, if Wicd connects to a wireless, i'd launch gksu arpon -d -i eth2 (for example.) But this doesn't work, because it seems that gksu only works for X apps.I found that if i do: gnome-terminal -e 'sudo arpon -d -i eth2' It works, but it leaves me with a terminal window open, and i'd like to be asked for a password gksu style.I've also tried this: gksu -- arpon -d -i eth2which also works, but the program quits right after it's started.Am i missing something here?
