I created a ram disk with this command: sudo mount -t tmpfs -o size=2048M,nr_inodes=500k,mode=777 tmpfs /var/cache/apt-build/build When I run apt-build, I got an error message that the disk is full (unable to copy file or something). But no disk was full when I checked with 'df'.
we know the maximum of files created from the nr_inodes number? Or is there any other option that determines the max number of files created?
On Debian Etch I used to understand how to change boot kernel parameters with Grub. You could just edit menu.lst.
With the newer Grub in Squeeze I am without a clue! I want to set up a ramdisk, say 128 Megs in size, and add that to my boot parameters so that it is created every time the machine starts. Do I set something in /etc/default/grub ?
How do I recursively generate a text file which has a list of all files on my server which contain a specific string anywhere in the files?
I know the following command can be used to replace a string recursively
find /var/www -type f -print0 | xargs -0 sed -i 's/old string/new string/g'
I do not want to replace the string, I just want a list of all files which contain the string.
Once I've booted my Etch install disc, are there some parameters in configuration files I can edit in the ramdisk filesystem that will allow me to install Squeeze instead? Or, even, paramters I can edit to point at the archive.debian.org repository to install Etch?
Why:
I've got a Sun Ultra10 with IDE drives (hard disk and cd drive) on which I previously had Etch installed. I recently tried to upgrade it to Squeeze, botched the upgrade, and formatted the drive. I'm now trying to install Squeeze from scratch.
When I use the Squeeze disc (debian-6.0.0-sparc-xfce+lxde-CD-1.iso), it cannot detect my IDE drives. I also have the disc I originally used to install Etch, way back when. It will boot and detect the drives, but cannot install because Etch is no longer in the repositories.
the permissions for my home directory were accidentally changed from 'access files' to 'create and delete files', and I changed them back, but ever since then I am not able to change any preferences/settings at all. power management, themes, panels, emerald, anything. my user account is supposed to be the administrator, and all the user privliges are checked. how to get control of my computer back?

Anyway, 11.04 has hit and since I'm dealing with office machines and software developers who expect a stable environment, I want to hold back 10.10 as long as possible (or at least "as long as I need to test things"), both on desktop and server installs. I'm looking at 130+ other updates in Update Managar today and when I hit the install updates button I had to fumble for the cancel button because it went to the dist-upgrade screen. How can I tell what packages will trigger the Ubuntu upgrade so I can freeze them?

I'm trying to boot windows 7 on virtual box, but it seems to demand quite a bit of memory. The "recommended" amount is 512MB, and upon checking my kernel only has 488MB total ram with not much room to spare:
Code:
billy@billy-desktop:~$ free -m
total used free shared buffers cached
Mem: 488 462 25 0 53 193
-/+ buffers/cache: 216 271
Swap: 1939 17 1921
I've tried giving the virtual machine memory sizes in the area of 192-256MB, but that's way too much and the system locks up and aborts from it. Memory sizes in the area of 128MB is just too small and it throws an error that there just isn't enough ram to boot. So the only thing I can do to make this work is to increase the size of the ramdisk for my host OS so I can give more to the virtual machine (not to mention things like flash animations are horribly slow and I'd like to see them get more fluid).
I see that I have 16 ramdisks available to me:
Code:
billy@billy-desktop:~$ ls -l /dev/ram*
brw-rw---- 1 root disk 1, 0 2010-02-17 09:54 /dev/ram0
brw-rw---- 1 root disk 1, 1 2010-02-17 09:54 /dev/ram1
brw-rw---- 1 root disk 1, 10 2010-02-17 09:54 /dev/ram10
[Code]....
I looked at some guides here and there, but apparently my setup isn't quite the same. I don't have a menu.lst file in boot/grub, and I don't have a grub.conf file anywhere. So I don't know what file I'm supposed to edit for this.
Trying to mount a ramdisk on demand when I need one, however gksudo is griping that the command is wrong. So, what's wrong with this command?
gksudo mount -t tmpfs -o size=1024m tmpfs /mnt/ramdisk

it's just that dpkg isn't picking it up.What is going on here, and how can I place a package on permanent hold?

sudo aptitude install wine1.3 ttf-mscorefonts-installer= but I don't believe that the package is actually on permanent hold.
I need to quiesce a VM manually and for that I need to somehow pause VM and hold incoming I/O requests.

View 2 Replies View RelatedI can think of a lot of different situations when being able to "autoclick" would be really useful. By autoclick, I mean that I want to be able to hold down the left-click button and have it rapidly clickity clickity clickity as fast as the processor can handle.
One example is games where I have a semi-automatic weapon and I have to hammer the mouse button with my finger. It would be nicer to reduce the wear and tear on my trackpad.
I would like to configure the eth0 manually. I can configure the ip address and sub-netmask but the system can't hold my gateway ip address (I added). It will keep it 0.0.0.0. I have no problem when I getting IP address from DHCP server.
View 1 Replies View RelatedInitially on a fresh install, I install an icon theme to /usr/share/icons and a few extra icons that I use in desktop, taskbar, and menu launcher icons to /usr/share/pixmaps. Anyway, it all works just fine. Again, no problems at all.
Today, I decided why in the world would I separate the two, and why not just put all my icons inside my icon set in /usr/share/icons, and then just reset those launchers. No biggie.
However, for some odd reason icons that I've set in launchers on my taskbar and in the menu won't stay/hold, and it just remains a generic icon. Why? They are the EXACT same icons that were in /usr/share/pixmaps. All I did was put them inside /usr/share/icons/my-theme. I don't get it.
And just to see if it worked, I put them back inside the /pixmaps folder and they work. So obviously, not a big deal, but I would love to know why. What is the difference that is preventing me from having them all work in my /icons folder?
I've refreshed, restarted, and retried over and over to see if it was just a glitch, but to know avail.

Having trouble figuring this out. I've got a package that I've installed from out-of-repos and Kubuntu feels the need to "upgrade" this package to a version that I do not want to use. I've found out how to do this in Ubuntu, but not in Kubuntu. A commandline solution would be fine, although I've googled it and not come up with any working results.

For example, sometimes when I create a bookmark in Chrome, you click the Folder button to have it popup a list of folders where you can put the bookmark. Sometimes clicking this causes it to pop open and stay open. Other times clicking it opens it for a second and then it immediately closes. To be able to select a folder when its acting like this I have to click and hold the mouse button and then select what I want while continuing to hold the button. This doesn't only happen in Chrome. Sometimes it happens while setting ubuntu settings in the OS itself or in other applications.
Is this a bug? Why is the behavior inconsistent?
how could i mount the whole system into the ramdisk?I follow the article "http://www.linuxquestions.org/questions/red-hat-31/building-a-diskless-redhat-enterprise-linux-cluster-765393/",and it works.when i use the "df -h" on the diskless client .I find many system driectory is mountted from image_server.when i stop the connection between img_server and diskless client,the diskless client stop working. my question is how can i mount the whole system into ramdisk.

I use another kernel on my eeepc which is specially adjusted for the Hardware Needs of this little machine.
The source of this kernel is: [url]
But since today I have the problem that the updater would like to update the vanilla kernel from the Fedora Repos.
Even though there aren't any versions of this vanilla kernel already installed. So I don't know what causes this mistake and would like to prevent this kernel from auto-updating.
I have seen a few options out there but, has anyone know of a real good piece of software that you can use a internal voice modem in place of a on hold music device? I think it's out there but I haven't found a decent one. I have seen them for answering machines and such, but an on hold would be cool.

I'm using some milters on a Sendmail box that recommends using a RAMdisk [tmpfs] to store temporary files, the performance benefits of which are quite noticeable. However, the problem is if a huge number of messages are all delivered at once this partition can be pushed off the physical memory and into swap. When this happens the performance tanks to about 1/20th to 1/30th of normal.Is there anything I can do to keep a tempfs from being swapped to disk?
