I'm trying to get my backup script to run every week, but as a normal user, and not as root as it is done when the script is placed in /etc/cron.weekly. Anacron fits my needs in the sense that it doesn't require my computer to always be on, as opposed to cron, and will just run my script when it can, but at the most each week. Cron fits my needs in the sense that I can run the script as the user I am logged in as. The particular script backs up my home directory with rdiff-backup, and it is very convenient that I am the owner of that backup, since when root performs the backup, I am unable to browse my own backup files and must use "sudo" to do this.
Is there a way to let me use the feature of anacron that allows my computer to not always be on, but still get a weekly execution, and also run the script as a normal (non-root) user?
I am working on a large program in C to run on Puppy Linux. I have multiple pthreads running. I want to be able to set the pthread SCHED_POLICY and priority in my program but I want a user to be able to run the program without root privilege.
Using a sticky bit and root ownership gives the user too much power because they will be able to write and compile their own scripts. Is there a way to use 'sudo' when I set the thread parameters from my program or something like this?
I have a machine that I leave on overnight, and noticed this morning that it had suspended. Interestingly enough, the syslog makes it look like it's resumed during the same second that its suspended (or it might just be that it's very early here and I'm reading this wrong). I am certain that I didn't catch it that quickly. I've attached the relevant bits:

Ubunto 8.4, running on 2nd partition on Apple Intel iMac. Several months ago, following a routine update, I found I could no longer install routine updates. Investigating further, I find
"You don't have permissions to..."
then sudo: /etc/sudoers is owned by gid 1002, should be 0.
That's not me! I am the owner and root user of this computer. How could this get changed? How can I change it back to me? The Linux platform of the computer has not been exposed to the net except for Ubuntu forums and updates. No one else has used this computer.
building an install cd or dvd media that will automatically install the Linux software on a client pc. There is no network connectivity so the client can only be loaded with Linux from CD or DVD media. The crux of the matter is that I can not automatically install the Linux software on client WITHOUT typing linux ks=cdrom:/ks.cfg at the boot prompt.
I want to avoid any user prompts and just have the software install with the RPMS that I need for this client pc at the boot prompt. Actually, when the boot prompt commences, I would like the software install to start with no user intervention. I've tried several different methods in isolinux.cfg, but the OS always wants boot prompt for the cdrom. Can the boot prompt information be read automatically from the isolinux.cfg with out user intervention? I'm looking for the same behavior as a LIVE CD that kicks off with no boot prompts after a few seconds. Here's a copy of my isolinux.cfg
default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg

I haven't used my VB for a few weeks however all of a sudden it refuses to work for my normal non-root user. It's almost as if it can't find libraries in the /opt/VirtualBox directory. Initially it refused to start completely so I linked the required libs into /usr/lib64 ( yip real hack. Then it started but a vm would not start, and comes up with an error about a missing lib again which is definitely there. My non-root user is in the vb group and nothing besides system updates has changed. vb 3.2.10 slack64-current.
View 14 Replies View RelatedSo, it is my understanding that Ubuntu's automatic updates do not install ANY updates that are not "important security updates." For example, it did not upgrade me to Firefox 4 automatically; I had to do it myself (Don't all new browser versions usually contain new security features/patches? Oh well...That is a separate question entirely).
ANYWAY, is there some way to get the latest stable versions of all of my open-source software automatically (or at least all at once, on command), instead of just security updates? It seems silly to have to install new versions for every program manually.
Also, related/side question: Now that I have installed Firefox 4 myself (via apt-get by adding the mozilla-stable PPA), will I stop getting security updates for Firefox through the standard Ubuntu update manager?
Actually, a really thorough explanation of the whole automatic update system (or a link to one) would be great too.
I wondered if there is a way for quick installation, what I mean to install without any details given by user, just type one command and installation will begin and untill finish. Installation will not ask any details from user (like the user is passing next next next ... to all installation screens).

View 5 Replies View RelatedI am running on 11.2 and i have added some repositories, like Packman, KDE 4.4 Factory, KDE 4.4 Community.I would like to have this packages automatically updated which seems not to happen. If I look into software management every now and then, I always have to "switch system packages" to get the updates via the the updated applet.So I was wondering, if it could be due to a wrong priority for those repositories? Is a high or a low priority the point where the applet is looking from which repo to update? If not, what is this priority used for?

View 1 Replies View RelatedUbuntu 9.10 Karmic Koala. Dial-up Internet connection. I turned off automatic updates before ever connecting to the Internet. When I checked for updates manually a few days ago, forty-some files downloaded. A few of them were quite large, perhaps a megabyte or two. Several of the files near the top of the list were marked as "Failed". There were no failures farther down the list.
After they were all downloaded, Update Manager tells me that 315 updates are available, under the two headings, "Important security updates" and "Recommended updates". The "Changes" box at the bottom of the window says that the list of changes failed to download. I ran the Update Manager again but it quickly told me (in effect) that there was nothing new since the previous check, and nothing more was downloaded. The descriptions of the updates are horribly inadequate. And I *am* looking at the long decriptions in the box at the bottom. For most updates the information is not adequate to determine what it does, whether it would have any effect on my particular system, or whether it would benefit me. For example, near the top of the list of 315 updates:

However, I really don't have a need to know the root password; as the only thing using root, is for ssh authenticating via ssh keys. What I want to do is automate the root password change monthly via a cron job, to a random value. Is there a way to do this without knowing the previous password?

View 2 Replies View RelatedI no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.

All this is fine when the installation is complete, it asks for reboot. Reboot done. Then I went to terminal. Did a SU - root to get into the root. Then I did a firstboot command to enter information. I created a user for myself and at the end rebooted the virtual box.
When it starts up, it does not show my user. It just shows "Automatic Login" and it logs in as Live System User. Even if I try to switch user then it gave me a authentication failure when I enter the credentials of the user which I created. If I try to create users manually using system administration, the user is lost after reboot. I have tried all possible steps...as instructed on the net.

I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.
