Ubuntu Security :: Is Restart After Updating Necessary?
Apr 4, 2011
Every now and then, ubuntu update includes new image (initrd.img or something like that - a new kernel as I understood) that requires a restart of server after installation. How safe is it not to restart (and still use old kernel) for a while (until next scheduled service in a month or two)? The computer is a server and I don't want to restart it unless there are security concerns. Is there a page that tells you what are the changes in the new kernel? And if there are any security holes that have been patched? I'm currently using img version 2.6.32-28-server (and there is already 2.6.32-30-server).
I've installed Ubuntu server and got everything setup pretty well.My problem is apache.I put my website in /var/www and changed the security on the files to allow them to be executed by other, which is what I finally discovered was my first problem (access denied). But now whenever.I go in and edit my page, the changes aren't reflected on the site unless I completely restart apache.I know I'm doing something wrong because I used to pay for a host and every time I edited a page, it was instantly updated on the site. Could one of you gurus tell me where I screwed up?
way of updating only the security packages on CentOS?
If I do a yum update. It updates everything and creates a new version which will unnecessarily uses space along with the old version. I don't want this to happen. way of updating only the security packages and keeping my old version of CentOS?
I had a buddy that swore he was such a linux guru he could bypass the lock screen easily but refused to elaborate. Was he just being faseeshis or was he legit. I don't accept starting a new X session using the terminal or restarting and using recovery tool to change password as an answer.
I'm using RHEL 5 with the Enhanced Security. Using the suggest NISPOM Red Hat documented settings (located on the system; copy - paste) I have managed to audit failed file open accesses however, this setting only retained if I enter it at the command line (/sbin/auditctl -a ). If I reboot the system or restart the service all my -a (not -w) located in the /etc/audit/audit.rules are not retained.
I run apache on a non standard port(82).I just installed unity to play around with it and while I was playing with it I installed prixfixe through software center to edit the menus.While prixfixe was installing my computer was acting very slow which was odd, but not completely unusual.During this time I ran ps aux which showed that my apache server was taking up most of the processing power.I was about to stop my web server,but I waited just in case the web server was updating a few things (I run ampache).
My computer finished installing the software and then I ran some command with sudo (I can't remember what the command was), but it threw back some message saying "setid blabla". I restarted my computer and when I got to my gdm my normal user account did not show up. There were no accounts and the restart/shutdown buttons didn't work.Now I'm running on a livecd and checking out my apache access logs, apache error logs,and kernel logs,but nothing looks out of place..
I have a 3dsp pci wifi card, and the last kernel it supports is Ubuntu 10.04 2.6.32-(21-24) I want to update but dont want to accidentally update the kernal.
I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)
"name@name-desktop:...$ "
I'm on my phone now so I don't actually have the symbol for before the dollar sign but your know what it is. The raised S on a 90 degree angle.
I have a suspend problem in my laptop. Sometimes, when resuming from suspend, the network adapter is down (that is, the network does not work and the light of the network adapter is off). Restarting the network service doesn't work, because I think that the system forgot about the hardware, and probably the driver should be reloaded.Does anyone knows how to do that?(ps. /etc/init.d/networking restart does not work, because the hardware driver is not being recognized anymore).
i have installed dhcp,there i declared the subnet and network,i used command include "/etc/dhcpd.conf.jutu1"; to start and other files, but it show me this error when i want to restart the DHCP, if you need more information contact me, i have configured this file too jutu1, but it don't let me to restart dhcp from /etc/init.d/dhcpd restart, this show me this message
Whenever I choose "Restart" from the GDM screen, GDM appears to shutdown, and the first TTY is displayed with a login prompt at the bottom (assuming I haven't used that TTY). I am by no estimation a patient individual, but I waited a solid minute or two for something to happen, but nothing ever did. I end up logging in as root on that TTY and running "shutdown -r now" to get the job done. This is a shared computer, and ideally any user should be able to perform shutdown options graphically from GDM.The only mentioned workaround doesn't apply to me as I am using the nvidia driver, not intel.
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
Due to networking issues within 10.04, I can't connect to the internet to update to 10.10.
I've created an install CD, but want to confirm if I'm doing it right, or how to fix some issues I'm seeing.
First, I get the option to create besides my other OS (Vista and currently 10.04). I've tried to select this option, and it gives 3 options to install:
An SD card I've left in my computer
Sharing my Vista HD Sharing with 10.04.
The issue is that when I got the computer, I partitioned my second HD (320GB) in half, one that is shared with Vista as a storage dump, the second half Ubuntu (160GB partition).
Currently, using this option forces me to split this half partition between Lucid and Maverick. For some reason, if I try and "use entire partition" the bar shows 2GB as the size of the partition. If I choose use entire HD, it shows the full 320GB. Using the slider can reduce the footprint of Lucid, but can't wipe it out.
Since I haven't screwed around with partitions too much in the last 3 years, I am not too comfortable with using the advanced option, but it seems like the only chance I have to erase 10.04 completely. This is reinforced by it asking about "device for boot loader"
So I have given up on running slackware on my labtop, beacuse I lack the knowledge on many of the settings and configs in linux. So I have decided to install Ubuntu on my labtop. But I know that I have to install 7.10 beacuse of mye graphic card, ATI Radeon Xpress 1100. I have allready downloaded the driver install file for my graphic card.
The thing I am wondering on is this : I am thinking on installing the drivers right after I install 7.10 and after that I am thinking of uppgrading to 9.10 if its possible. And the thing is, will I keep my ATI drivers installed if i update?
I have uploaded a newer edition of WINE through a ppa to 'sysyem-admin-software sources', but would like to know how to update wine so that it utilises this ppa upgrade as i cannot get linux to recognise the update.
I recently re-installed Ubuntu Karmic on a new PC (about a month or so ago), and I just noticed that my PPAs are not updating when I run the update manager. I'm not a complete noob but I'm not all that hardcore or experienced. Is there something I am doing wrong?
When adding a PPA I open System>Administration> Software Sources and click on the "other software" tab. After clicking "add" I enter the APT line (*eg. ppa:banshee-team/paa) and hit "add source". I hit close and let it reload and that's it.
This method worked fine for me before but now when I run Update Manager it never shows any updates for the PPAs I have added even though I know there is a newer version of the application available.
Ive just insalled Ubuntu 9.10 and installed Filezilla from the Ubuntu Software Centre, however this is only version 3.2.7.2. How do I update this to 3.3.2? Ive downloaded the tar.bz2 file and extracted it in Downloads but how I do install it from here?
I have installed ntp using Code: apt-get -y install ntp.Logging to /var/log/ntpstats has been enabled in /etc/ntp.conf however this directory is not getting populated with anything. I have also tried removing it with apt-get --purge remove ntp and reinstalling but to no avail.
I was just wondering once the 10.04 LTS is officially released will it be possible to just update the packages of 10.04 beta 2 to make it the official release or will you have to update, or will you have to actually do a reinstall?
I'm having some issues with Amarok not displaying songs in the "local collection" as well as not shutting down properly. I see that I am running 2.3.0. If I run apt-get upgrade amarok I get a message saying nothing was upgraded. But I see on their website that 2.3.1 is the current version. I'd like to try to update to the current version, but can't seem to find the right repository to add. Anyone know who I might be able to achieve this?
How do I get into safe mode of something of the sort? I thought all I had to do was tap F6 as the computer boots up, it was running perfectly untill I updated it, when I pressed restart it started to shut down and then it just got stuck in a black screen with a small white cursor flashing, and there it stayed I've restarted it a load of times and no luck, I was getting ready to reinstall it when I remembered that I have no other cd burner in the house other than the one on the machine that's just packed up and though I could use a flash drive neither of the 2 I have with me are big enough, the bigger ones are both at work along with my ubuntu instalation CD.
On a second probably unhelpful note I'm getting really fed up with ubuntu it's proving to be about as unreliable as windows, every other week for whatever reason it fancies it just packs up and more frustrating for me is that while I know my way around windows and can usually sort it out I haven't got a clue about how to sort Linux problems out and before anyone mentions it yes it was a relatively new instalation, all I had installed on it other than the OS was the updates up unlit now and XBMC and it all had been working flawlessly for 2 weeks or so!
I have just created a back up script that would backup my system into two (root and home) tar.bz2 file. that was good and well. The thing is though I also created one that I thought would update the tar.bz2 files using the "u" (update switch). it seems that it won't work though. I did a search on the matter and found a thread in the Linux Forums that was saying that "gzip" couldn't be updated.
Is this the same with bz2? Is there a way to get it working? it would be handier than creating new bz2 file every time as it takes so friggen long to run the full backup (and thats even after excluding what I don't need).
I had Ubuntu 8.04 & Windows Xp installed on by 80GB Hard Disk by giving 40GB each to Ubuntu & Xp. Due to some problem in Windows Xp (nothing new) i had to reinstall Windows Xp. I had taken backup of all data on Windows & Ubuntu fully knowing that Grub would go haywire.
Now i want to install Ubuntu 10.04 on the 40GB that was earlier occupied by Ubuntu 8.04 from CD.

I am running 10.04 32-bit on my compaq nc6320 laptop and I am just wondering if there is an easy way to do the upgrade to 10.10 but upgrade to the 64-bit kernel.
I was using 9.10 because of my wifi not working in 10.4 (still does not but thats not the problem in this thread) well after getting my updates to update to 10.4 I run the package manager to update kernals and such, first it says theres an error failed to fetch CD then I reset my computer and it says my system is up to date but I do not have an option to upgrade to 10.10 and im sure theres updates my computer does not have..
