Ubuntu :: Schedule Unattended Updates To Install At A Specific Time?
Dec 8, 2010
I've been quite puzzled by the behavior of unattended updates - it seems it runs the updates at or before 7am (on all the server installs I've got). They are only set to do security updates unattended, but what I am wondering is if there is a way to change the time that they install? I want the updates to install early in the morning, at like 3am or such, so I can reboot the machine when I get up if needs a reboot.I found a few mentions about it, but nothing specifically talking about the time.[URL]..
When I leave my computer and later return, depending on how long I've been away, I find the screen-saver running, the screen turned off, or the computer suspended, i get the error as specified below on a black screen:
Quote:
Ubuntu is running in low-graphics mode.
Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.
The message gives several options. Despite some experimentals, The only solution which I have found is to reboot and everything becomes fine as before.
My Internet service provider here in South Africa is Vodacom (Vodafone) and I pay a huge amount of cash for 2.5Gigs per month. They do, however, give me the same amount of data for free that I can make use of between midnight and 5.00am.For this reason, I would like to be able to schedule my update manager to download all updates at, say, 10 past midnight.Can any of you guys out there offer any suggestions or is there a way that we can make a request for the Ubuntu developers to include this in "Update Manager"?
I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.
I've been running 10.04 on an old tower for a few weeks now. I've updated the software with no problems. Yesterday I let Update Manager go ahead with installing some updates. Now, the computer will crash while unattended. The screen stays off, and the machine doesn't respond to pings. I've found nothing of use in the syslog. The display going to sleep isn't the trigger, as it will turn off and come back before the issue presents. It seems to occur after 15 minutes or so of idle activity. Also, after an update a couple weeks ago, linux-headers and linux-image won't install cleanly. I'm going to try disabling power saving features to see if it continues occurring.
I've recently installed the unattended-upgrades package on a few Ubuntu 9.04 servers, and it's working great to automatically install security upgrades. However, is there a way to have non-security upgrades automatically installed as well? The README for unattended-upgrades says it'll do security ones only.
My main goal is to have all package upgrades be installed unattended except for kernel and libc upgrades (I want to do those manually on my own time). I guess I could write a script that does 'apt-show-versions -u' to get a list of upgradable packages and then do 'apt-get install' on the packages if their names don't match linux-server, linux-image-server, or libc*, but I was hoping there's an easier way to accomplish this.
I've looked at 'aptitude safe-upgrade -y', but I think that'll install kernel and libc upgrades.
I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.
I have Ubuntu running as a Virtualbox, and every time it upgrades the kernel, the Guest Additions stop working.The install process in Linux requires using a virtual CD, running scripts from the command line, etc.Is there any way to keep the guest additions constantly working even when the kernel is upgraded? Can they be installed as Ubuntu packages instead of installing off the virtual CD?
I have a select few users (finance dept.) at work who want to be able to write to a calendar based program on the network that allows them to schedule time / days off. The calendar or program needs to be writable by only a few administrators so that once time off is approved by their manager, he or she is the one who would access the application and submit the entry on it's specified date / time.
I would prefer if the back end is SQL database compatible but doesn't need to be since at this point I need to find anything that will fulfill this request. Obviously this sounds like a web / php based application that would run on my Apache Intranet web server
I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.
I have to create an unattended install from an USB with special instructions. Unfortunately I'm a newbie and I have no clue as to where to start. We did recieve one link to use and I still don't understand what I'm supposed to do. The link is on the CentOS home page.
Can an unattended Kickstart support both IDE (hda) and SCSI (sda)? The goal is to to create a new virtual machine from scratch. What I have works for Parallels in which a new VM defaults to emulate an IDE hard disk. It does not work for VMware Workstation which defaults to emulate a SCSI disk.
The relevant Kickstart section: bootloader --location=mbr --driveorder=hda --append="rhgb quiet"
I would like to create an unattended install ubuntu 10.10 cd. I have followed the ubuntu [URL].. on creating the preseed file, however, I can't find any useful tutorial on how to set the kernel parameters to perform an unattended install using my preseed file.
When I installed 10.10 I uninstalled gwibber, empathy and ubuntuone. Twice now in Update Manager I've subsequently found gwibber on the list of possible updates. Is there a way to tell Update Manager not to include in future some programs, which I've uninstalled and don't want?
So at work I usually forget to shut down my computer at the end of the day 5:30 and they switch the breaker off at 6pm which cant be good way to shut down a computer. So i was doing some googling and this is what i come up with.
this is the example i found online Code: #crontab -e -u root Code: 0 20 * * * /sbin/shutdown -h now since the above turns it down at 8pm i need to edit it to 5 30pm
Code: 0 17:30 * * * /sbin/shutdown -h now would this be correct?
For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.
How do you find a file modified March 17, 2010, between 3:30 pm and 4:05 pm? I know that I must be missing something somewhere.How do you search for info like this? I goggled "search files time Linux" and got about 38,300,000 results. I looked through the first four pages and did not see what I was looking for.Do I need to calculate how many minutes ago that is and give that to find.I really want to do this in the GUI so that I can operate on the files found without typing in so much stuff.
How to refresh a page automatically?Say for example i need to refresh page in ubuntuforums to get new questions.I feel lazy to refresh the page often.Is it possible to refresh the page automatically in a specific time interval?I have tried ReloadEvery Firefox Add-on.But it refresh all the tabs.What i want is i want to refresh a page in a particular TAB.
I'm running Ubuntu 10.10 in a computer with a 7200rpm HD, 8Gb Ram, and a Core i7, and the time it takes to load the desktop is insane. There are threads that mention the problem of gnome looking for nonexistent floppy drives and to solve the problem by disabling that in the BIOS (option I don't have). Anyway, besides that problem, by running at startup a gnome-terminal with the iotop command, I noticed that two processes have a huge i/o load on the system: google desktop and ubuntu one. I would like those programs to run as part of the startup process, but be launched after several seconds (to allow the rest of the programs to load). Is there any way I can achieve this? I think there should be a way modifying the commands under startup application, but I cannot find anything that works.
I'm looking to find a way to schedule my computer to wake up at say 7:00am. Every night before I go to bed, I put my computer into suspend so the fan doesn't wake me (old computer). I can't seem to find a task scheduler that allows me to be able to wake the system.
I have looked high and low for this, but to no avail. I am looking for a script to shutdown my computer when it reaches a specific time (say 10:00). I know about the shutdown command but if I use that I cannot shutdown my computer manually. I would like to be able to shutdown manually AND automatically.
I've just put together a 10.04 server using a GA-D525TUD atom board. I've installed gnome desktop too. I'm trying to get 4 sata drives to go into standby, but hdparm seems to be ignoring the settings. If i issue hdparm -y /dev/sdx the drive duly goes into standby and stays in standby until accessed. I've put entries in rc.local along with the hdparm.conf settings, but still no joy.
I am trying to extract just a few files/folders from a Time Machine backup, but can't seem to find them. The drive is automatically mounted in Ubuntu, and am able to access after enabling view hidden files, the HFS+ Private Data Directory. But that is a jumbled array of thousands of numbered folders, with each taking a fair amount of time to open on this aging Dell running 10.10.
I've tried running the standard Places - Search for Documents, with 'Show hidden and backup files' enabled, but that won't pull up any of the search times I'm going for (and seemingly won't find anything at all on the drive). So, is there any way to decipher the directory tree so as to be able to access this data from Ubuntu? Or perhaps a file embedded somewhere in there that lists out the original structure, so that I can use it as an index to see what number correlates to what originally named folder?
Can anyone shed some light in this? Using Fedora 14-64, new install, 185 Opteron x 2 gig ram, sata hard drives formatted Ext4.However, in my home directory I have a folder for all my digital photos of which I have more than 20,000, and in another folder I have images and clipart of which I have almost 8,000. That is a lot of read only access to a significant number of files in my home directory.
How can I tell Fedora to not update the LAST ACCESS TIME of those files (specifically images) that will never actually be changed other than just being read. I want to leave that feature enabled for the rest of my home directory. I am trying t; improve my disk performance in Nautilus because whenever I access the folders with my images the system literally slows to a crawl and sometimes even the mouse stops working for several minutes until Nautilus has finished having its heart attack.
I am using openSUSE 11.2 and had the same issue once before in openSUSE 11.1 After some time, two domains I use very often can't be accessed any more, these are: Google and [URL]... (am doing some OO development recently). At the time where I write this post, only these two are "blocked".
When I try to access these two domains using Firefox, w3m or telnet, it tries to open the connection forever. Ping works fine. I tried opening the IP directly in the browser, but same problem, the connection never reaches. I know it's not a router issue, as the other computers can access these domains. Still, I tried to restart the router, but the issue persists. I tried restarting the network service (/etc/init.d/network stop + start), also nscd, without success. The only way I found to make it work again is to reboot. This problem reappears from time to time, after using the computer for a long time, and accessing these domains a lot of times. Note that I also use suspend to disk, so the "blocked" state is kept after resume. Only reboot "cures" it.
