Ubuntu :: Force Grub To Ignore Specific Kernel Version?
Feb 7, 2011
I just upgraded my storage server to maverick and it seems the 2.6.35-25 kernel doestn like the hardware im using
since im pretty sure its a hardware related problem and the previous kernel hastn the issue im currently booting this old kernel everytime i need the server by hand (using Shift during boot for the grub menu to appear)
well, it narrows down to the following question:
how can i exclude a specific grub entry - in my case the current kernel 2.6.35-25 - so only previous kernels OR future kernels from the next updates will have a chance to boot?

I run a bunch of CentOS 5.6 servers, where we continuously deploy our software. Our software comes in self-made rpm packages from a network-local yum repository. As bugs happen in software development, I sometimes want to downgrade to the previous release, so force the installation of a specific version of the package.I tried the allow-downgrade plugin, but so far no luck. Neither yum update nor yum install seem to work with allow-downgrade. (It does not seem to do anything?). Does anyone have a working example for yum --allow-downgrade?
This is what I tried:
1) Show current yum version
[root]# yum --version

I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:
1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.
I've asked some people and I've just been told to "learn LD_PRELOAD". I've googled and can't figure how I could even apply that to my current problem

I am trying to run Ubuntu 9.10 from a USB drive on an old laptop with a dead hard disk.An added complication is that it does not support USB boot, only CD boot.So with the help of URL..., I am running grub from a cd and then booting the kernel from the USB (or something like that).
The problem is that after I do this, I get about 6 minutes of error messages as the kernel tries unsuccessfully to read my dead hard disk ("buffer I/O error on /dev/fd0" or something like that). I can post again if the specific error message would be useful. (But it takes so long to reboot that i'd rather not). I can tell it is trying to access my hard disk as I hear the disk occasionally spinning (it intermittently spins and does not spin). After many failures, the system successfully boots and runs from the USB drive.I tried removing the hard disk from the machine entirely, but this triggers an ASPI error and the kernel hangs.So ideally I would like to modify the kernel command line above to instruct it to ignore the hard disk. I read some kernel documentation but it proved a little bit too advanced for me.

I am just too tired and am missing something in the man pages for aptitude and not getting my search terms right but I can't seem to find a way to make aptitude ignore a couple of supposed broken packages (they work just fine by the way). The only way I can find to remidy the situation is to remove those couple of packages or upgrade several things to their Squeeze counter parts. I really don't want to try and do the upgrade as at home I am stuck on a 56k connection. Removing the broken packages I guess won't be too bad if I can find the debs again after I install a couple of things I want to add to my system. I would however just like to make aptitude ignore the state of my system and try to install what I want anyway.

I have a csv file that has around 3 million rows. I want to process this file so that it creates a new file that contains only the rows that have 2 characters or less in the first column column.At the moment i am using SQL Loader but its taking too long so im wondering whether this would be easier if done in Unix?

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?

I'm currently using Centos 5.4 but I wanted to avoid this upgrade but it seems impossible.
Is there a particular block /ignore list so that yum doesn't upgrade the system in future?

I've got a machine running 9.10 with two network interfaces, one being motherboard based (atl1) and the other in a PCI slot (e100). By default at boot the interfaces come up in the wrong order. I'd prefer to have the e100 come up as eth0 instead of eth1. And then have the atl1 come up on eth1 instead of eth0. Both interfaces use static addresses and IP4 routing should be active across them. Where do I configure things to force the specific settings?

I need to actively make sure some files, in a specific directory, are chmod 750 and owned by transmission:media-daemons. Other users will save to this directory, with other permissions and UID/GID but I must make sureto reinforce this default.
So I have this on my /etc/crontab:
Code:
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

concerning controlling the windows in virtual desktop.
a) Say to a application to be launched to virtual desktop 2 for example.
b) How can you ask from a virtual application to be only visible at one virtual desktop. For example I work on virtual desktop 6 and I want to start skype that should be on virtual desktop 2. Right now If I launch the app on virtual desktop 6 it will appear on the same one. Would it be possible to ask for an applicaiton to be launched on an other virtual desktop. If yew how?

I'm hoping some of the Linux network experts can help me with this problem.
Situation: I have a technology which is a WebLogic JEE application that communicates to an Oracle database. Everything is installed in a single Linux virtual machine running in VirtualBox. Traffic from the JEE application goes via JDBC over TCP to the local running database. What I want to do is test a new database firewall server that wants all traffic destined for the database to flow via another virtual machine running the DB Firewall software.So therefore want I need to do is have DB traffic forced out over one interface only to return on another interface on the same VM listening on a different address.
JEE application running in WebLogic bound to 192.168.111.12 (eth1 a VirtualBox hostonly interface). Makes a request for 10.0.111.12 (eth2 a VirtualBox internal interface) which the database is listening on. Because both IPs are on local interfaces, Linux is going to handle the traffic and not route the 10.x traffic via the 192.x interface.I also have running the database firewall server which has a bridge (br0) between the HostOnly network and the Internal network.Both systems are running Oracle Enterprise Linux R5U4, which is basically the same as RedHat.What I want to do is have the request for 10.0.111.12 forced out via 192.168.111.12, bridged over the br0 connection and back into 10.0.111.12 and to the database. My networking knowledge is pretty good, but i'm stuck right now on the right way to do this. I'm pretty sure it is possible, I just need clear advice.
Reason for setup: Ideally I would build the system with the database on a separate machine so that I can easily route the traffic. Unfortunately we have many VirtualBox based demonstration systems with both the application and database installed on the same VM and therefore the amount of work to migrate these two dual VMs is going to be significant, also many of these VMs are demonstrated from laptops which have limited resources and creating a new database VM reduces overall performance. If I can create a way to force the traffic in this manner off and back onto the same VM via the other VM bridge, it would be fantastic.

I generally have at least 4-5 distro's installed at one time - I always install grub to the boot partition of other distros -that was I control grub from the individual distros - I use ubuntu's grub as the default boot loader.
Rather than the method that ubuntu uses with the update-grub.I normally edit the grub.cnf file to add other distros but when update-grub launches it also adds links in grub.How can I prevent the upadte-grub script automatically adding lines for other distros i.e - I just want it to add ubuntu entries and ignore other partitions.

Added software from a PPA I use to get up to date programs, during the update empathy was deleted. I went back and deleted the new software causing the conflict but empathy still won't install. I see there are two versions, 3.1.1.1 and the ubuntu 11.04 2.3.4 I think. I want to install the natty version but whenever I try force version it gives me an error. Is the solution removing the ppa? or is there a work around like downgrading back to the original software?

I have the suspicion that the latest gdm update (2.28.1-0ubuntu2.2) broke something because the login screen isn't displayed anymore on my desktop. My question is the following:How can I revert an update or force a package version via command line? It's pretty straight forward via Synaptic but I only have access to the recovery command line so that is not really an option.

I've recently installed openSuse 11.4 64bit with KDE 4.6 and that's when the trouble started. If I put a data or mp3 cd in the drive it can be mounted. Simple audio cds refuse to mount, giving me only the option to play on one of the audio players. Since I wanted to move some music to the computer I've had to resort to windows to copy files then transfer them. How can I force KDE/Suse to behave the way I want or do I have to revert to an earlier version with KDE3.5? I suspected that System Settings/Removable Devices was where I needed to be but nothing I did worked. So then I tried playing with System Settings/Device Actions and again nothing seemed to work. I can't mount the CD manually,I get this (using su -c "mount etc"
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can't read superblock

Sometimes a kernel image seems to have the same version as the backported kernel image, for example:
linux-image-2.6.32-bpo.5-amd64
linux-image-2.6.32-5-amd64
What are the differences between the two?

I have set the kernel selection time out to 3 seconds. However, sometimes it just hangs indefinitely on the kernel selection screen until I manually select the kernel. This is bad news since it is a VM started up from a script and _has_ to start automatically. The VM is a re-constructed cloud backup made by rsync and re-running grub.
Is there any way to force Ubuntu to NEVER, under any circumstances, not time out on kernel selection.

I'm using VirtualBox on MacOS and I need to install version 10.0.4 of Ubuntu.The setup for VirtualBox only allows you to specify Linux > Ubuntu (64-bit).How can I install a particular version? I've been told that you can download it as a disk image and install it in VirtualBox somehow: can anyone point me at more details?

At the moment I am using kernel 2.6.31-14-generic. I'm not one of those people who needs to have the latest and greatest kernel to be happy, I just rely on the update manager. I swore that I saw an update for a new kernel, but my kernel version hasn't changed. I'm just curious if there was a new kernel that was released or if that was just an update to the kernel listed above.

I've been using Linux for over a decade, so no need to worry about the obvious. I'm positive that I have my partitions/install correct. What has me baffled is that Fedora 14, which uses GRUB 0.97 (GRUB legacy) - boots Windows flawlessly every single time on the same hardware, but Ubuntu's (or the upstream Debian's) GRUB legacy do not - even though they are based on the same upstream code from the GNU Savannah servers.
No matter what I've tried I cannot get the Debian or Ubuntu version of GRUB/GRUB-legacy to boot any recent Windows 64 beyond XP (Vista or 7). All that it does is resets the computer when Windows attempts to boot, without an error. GRUB is notoriously difficult to compile, so before I try to compile code from RedHat's archives - any thoughts,experiences, similar issues - whatever?
