Ubuntu Servers :: Ltsp Fails In Tftp Under U9.10 / Sort It?
Feb 17, 2010In Jaunty (9.04) I've setup a small (eleven-terminal) ltsp network at the local school. It handled around 6600 working hours with ease.
Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.
Ubuntu :: Getting Kernel Panics While Booting From LiveCD / USB
Feb 17, 2011I just built a computer with these specs:
Asus P7P55D-E Pro Mother Board
2 x 4gb GSkill RipJaw 1333
Intel Core i5-760 cpu
MSI nVidia GeFore GTX-460 Video Card
When I try to boot from a live CD/USB I always get some sort of kernel panic, most times about USB controllers and other times about cpu_idle. I have pictures of these that I can post but nothing from any logs because this is happening even before I install. I have left memtest running over night for 11 hours and had no problems, I have tried to boot with only one stick of memory, I have changed the video card to a GeForce 8800 and I have tried everything on a different motherboard and still no luck. Would I wrong to say that there is a problem with the CPU and should I return it? My only problem with all of this is that Windows installs perfectly fine on the computer with zero problems...weird.
Ubuntu :: Kernel Panics In Natty All The Time?
May 10, 2011I have been a happy Ubuntu and other distros user from 2007 to now. Had my old 7.10 Gutsy Gibbon (Ubuntu Studio actually) that I really felt was time to upgrade. Then I downloaded the ISO image for 11.04 Natty Narwhal past 4 day ago. It gave me an option to install on my old 7.10, upgrading it, then I chose that one not to have to lose my data.
At the very end of the installation (when downloading several packages from the net) I got a kernel panic.
After that I reinstalled from zero wiping the whole partition, with the same results. It only worked when I disconnected the net cable so it wouldn't download anything during install. Then I could run the 11.04, but kept getting kernel panics, and after some testings (I thought it was the nvidia video drivers at first) I think it happens after some ammount of network traffic happens.
Memtest went normal, I tried logging with no-effects and I tried some solutions from forums with no results. The pc can be on and working for hours, but after I start surfing the web for some time, I get a freeze. Sometimes Caps Lock and Scroll Lock leds are flashing, and sometimes just freezes to simply become unresponsive. When it was during the installation I got a message saying it would pop out into console because panic occured and then froze. Anyway I always have to press the reset button.
I would like to be sure if I have some of my hardware broken or if the newest kernel is still green on some hardware support; maybe network. I'd also like to know if I can install older versions of the kernel; I think that should fix the problem because other distros worked perfectly here before. I also heard about some kernel-image-pae being different from the ordinary kernel image. Could it help if I change that package? I'm waiting to install 11.04 in my wife's computer also but of course I don't want to bring any problems on her! My net card is Nvidia Nforce and my processor is AMD Athlon II X2 with a GForce 9400 for video card.
General :: App Segfaults Every LiveCD/DVD Kernel Panics?
Jan 23, 2011My friend's PC recently started acting up. He had me install Sabayon on it and everything was fine until a few days ago. Every app I try to run after the PC boots results in a segmentation fault. I figured maybe something was wrong with the HDD, so I tried to boot from a DSL liveCD to run fsck, but it wouldn't boot; it freezes right away. I then tried the Sabayon LiveDVD and got a kernel panic.Does anyone have any idea what the problem could be? I am completely clueless; I've never had anything like this happen before.
View 3 Replies View RelatedGeneral :: Kernel Panics - RAID Or XFS Related?
Jun 21, 2010After building a new system I have been getting kernel panics randomly. I have been able to look at /var/log/messages and determine that either my RAID card, XFS, or something along those lines is causing the problem. It has now gotten bad enough that any heavy use of the RAID will cause it to panic and die.
There is one large file on this that I need which is not on my backups but when I try to get it off, the transfer will cause a kernel panic within minutes. What is causing the panic? Is there any way to resolve it? The RAID card is an LSI SAS3081E-R and I am using the built in drivers/modules within Ubuntu 10.04 x64 (pretty sure the kernel itself has the driver included). There is source available for the driver from LSI's site but I'm not sure if that will solve the problem and in addition to that, I can't figure out how to compile and install it. It has a Makefile already but make just complains "no targets".
Code:

CentOS 5 :: Install DVD Starts And Then Kernel Panics
Apr 29, 2009I'm trying to use and old Dell Dimension 2350 workstation with 1GB of RAM and a 200GB drive as a home server. I boot the CentOS 5.3 install DVD, get to the splash screen and hit ENTER to start the install. The install routine starts and then kernel panics with a very long trace I can't make sense of. I've used the DVD for other installs so I know the media is good.Are there any known quirks to installing linux on a Dimension 2350? Maybe some kernel line parameters like no acpi?? As a test, I took an Ubuntu server cd, and the install actually completed but on reboot it kernel panicked with a similar long trace error. Obviously this is most likely a hardware issue.
View 4 Replies View RelatedCentOS 5 :: Random Kernel Panics / Correct It?
Jul 8, 2009I'm running CentOS 5.3 x86_64 on my laptop (dell vostro 1400, core2duo, 3GB RAM, intel 3945ABG wireless, nvidia video and LAN). The problem is that some times (like 15-20% of times) I shutdown the laptop, I get a kernel panic related always to the wireless kernel module (I haven't been able to get screenshot or anything). I'm using the latest centosplus kernel. I never get these panics with the standard CentOS kernel, however the standard kernel doesn't light the wireless led, and that annoys me a lot. Therefore I'm forced to use centosplus kernel. The question is not how to solve this (i know I've not given enough details) but what to do to diagnose better the cause of the panic and then correct it.

Sep 22, 2010I have this weird issue which only appears when I am using 64 bit Ubuntu. Every now and then my laptop seems to go into a kernel panic (system unresponsive, numlock and scrollock lights flash repetitively) only when I am using the broadcom wireless. I can connect to my wireless router and use the internet and local network, but eventually, kablamo, crash, bang, boom. The only way out of the crash is to power off completely. After repowering, the wireless network is fine until the next crash. There does not seem to be a pattern or time period to cause this crash either. I have purged network manager(which I couldn't get to use my wireless) and am using wicd, which allows me to connect wirelessly.
Here is the details of my system:

OpenSUSE Install :: Update To 11.3 And Getting Kernel Panics Randomly
Jul 22, 2010Since the update to 11.3 i'm getting kernel panics randomly. Because the X server freezes and I can only force an "unexpected reboot", there is not much information I have. I installed kdump and activated it with the Yast module. I'm collecting dump files, now. But I'm not sure what to do with does files.
View 7 Replies View RelatedUbuntu Installation :: Firefox Started To Crash Randomly And Led To Kernel Panics
Aug 2, 2011A while ago, when I was using Maverick, Firefox started to crash randomly and led to kernel panics.
So I upgraded to Natty (clean install) and Firefox there too crashed.
Then I was getting graphics and make problems.
Today I tried to install Fedora 15. It first boots to a Live desktop that warned me that my hard drive had 65000+ bad sectors. Sixty-five thousand.
So I got a new one. A WD Scorpio Black, 750GB 7200RPM with Advanced Format.
Again I boot into Fedora 15. OK, no bad sectors. I tried to run Disk Utility Self Tests but it constantly crashed. Fedora warns you about this.
In the Live session, I opened Firefox. It also crashed just like back in Ubuntu. Then the screen flashes black and got warnings after warnings that a kernel module has crashed.
So I took out my old Maverick installation CD and first tried a Live session. However, Disk Utility told me that SMART is not supported while on Fedora, it was.
So I tried to install. But soon after that, I got a warning that the installer has crashed because a file copied to the disk did not match the file on CD. Right now I am in the Maverick Live session.
Ubuntu Servers :: Kernel Errors - Syslog Output At Random Intervals
Jan 28, 2011I am running a headless Ubuntu 10.04 server with the 2.6.32-28-generic kernel. For what I can figure out no single direct cause I get a high load average and the following syslog output at random intervals. Generally the load average will drop back down to normal however the kernel errors will still continue What little I have been able to find has pointed to memory issues. I am not totaly convinced this is the cause as the server will be showing >50% free when the errors are happening.

CentOS 5 :: Install, Recurring Kernel Panics Crashing System?
Dec 27, 2009Recently switched my home server from Gentoo to CentOS and have been getting kernel panics consistently since I made the server "live". The machine was built with all new hardware. I'll post relevant configuration info and picture of the kernel panic below. So far all kernel panics have been with kernel "2.6.18-164.9.1.el5.centos.plus", right now I am testing with the kernel listed below to see if it does the same thing (2.6.18-164.9.1.el5).

Ubuntu :: Kernel Panic With LTSP And 10.4?
Sep 1, 2010I'm trying to set up a thin client to connect to an Ubuntu 10.4 64bit. The client itself is 32 bit.When booting the thin client, I get the following:
Code:
Begin: Running /scripts/init-premount...
No interfaces found! Aborting...
Done.

My main worry is, obviously, the kernel panic.When booting 64bit machines (a laptop and a desktop), everything works fine, but when booting a 32 bit netbook or thin client, I get the above panic.
Ubuntu :: LTSP Kernel Panic - Nothing Seems To Load ?

But my key goal is to get ASUS K8S-MX motherboard with sis 190 lan to boot so that I can set up a computer lab.
All seems to go well on boot but
When loading essential drivers, nothing seems to load and I get a done.
Then running /scripts/init-premount I get no interfaces found.
Then mounting root file system It starts Running /scripts/nfs-top and drops into kernel panic.
Ubuntu Servers :: 9.10 To 10.4 Upgrade And LTSP?
Apr 30, 2010Version 9.10 had been installed via the alternate CD as the LTSP Server Edition. In place upgrade to 10.4 completed normally via Update Manager. However, LTSP terminal boot now fails with error "Forbidden directory" and "Access Violation". The following was found . Ubuntu 10.4 uses tftp-hpa. Either this is a change from Ubuntu 9.10 or the default behaviour of tftp-hpa has changed. So now, the filename argument given in /etc/ltsp/dhcpd.conf must include the full pathname. The previous requirement was to exclude the chroot path. If this is documented somewhere, I missed it. And after modifying /etc/ltsp/dhcpd.conf, do not forget to restart the dhcp daemon $ sudo /etc/init.d/dhcp3-server restart

Dec 4, 2010I got myself a HP t5000 series Thin client to use on my LTSP 10.04. I changed the Bios to boot PxE. When i restart the thin client it asks for a DHCP and finds the LTSP-DHCP server all is good. Its got a IP address ok, the boot process starts. ok I get the Splash screen for Ubuntu. and all is going well. ok I no get a login screen. All is going very well. (As normal with Ubuntu). I can login all is good the login starts and i get the start up sound.But then where normally one would expect to get a desktop, one gets a login screen. Not knowing the full boot procses im not sure where to start to look. Knowing linux there would be a log file somewhere, that stores the LTSP Terminal Bootup/login process and would tell me where its stopping/failing.
The good news is that when i boot a fat client in all works ok and i an able to get in with a desktop.

Ubuntu Servers :: 10.04 LTSP Locks Up After 23rd Login?
Sep 3, 2010I am currently running LTSP on Ubuntu 10.04. It is a dual gig nic setup with 16GB of ram and dual AMD quad core 2.4s. I installed all the latest updates as well as likewise-open so we can use AD authentication. When testing the configuration in the lab, I boot 32 clients that successfully reach the login screen. Here comes the interesting part, I can log in, using all unique AD accounts, up to 22 clients. When I attempt to log in to the 23rd client LTSP hangs. If I restart a client it will retrieve an IP address, but TFTP will eventually time out. All of the clients are connected to a Gigabit switch along with the server so network speeds are not an issue. When I run system monitor it only shows 3.6GB of memory in use and the processors are all under 10% utilization. I have beating my head against this issue for 2 days .
View 1 Replies View RelatedUbuntu Servers :: Running Localapps In 10.04 LTSP Clients?
Dec 8, 2010I've successfully built my server, and any fat or thin client that I connect to it boots wonderfully, with great response. I've gone through this exercise because we need a more efficient way of testing computers before delivery to our customers. So, I'm trying to run Passmark's BurnInTest. I've run it before with previous versions (9.something, I think) and it worked well, but I needed to build a new server so we can test more computers concurrently, so I figured I'd get the latest release.
My problem occurs when I try to run BurnInTest - it must have root access to test the local USB, parallel, and serial ports, and the optical drive. For the previous iteration I used a script that dropped into a local xterm session, su'd to a root session, and called the BiT GUI. In this attempt, the same scripts, even when I single-step them manually, results in 'authentication failure' when the su is attempted.
I have enabled the root account and created a password for it in the chroot /opt/ltsp/i386, and rebuilt the image, multiple times, no joy. Using ctrl-alt-F1 I can log in as root, and using dmesg I can see the USB device register when I connect it, so as far as I can tell the root account is alive and well, just not available in a local xterm session for some reason.

Ubuntu Servers :: Install Ltsp On 10.04 Without Hard Brainfucking?
Apr 1, 2011In internets there are lot of successless stories installing ltsp on ubuntu 10.04. Most problems are in ndb, init scripts and somewhere else, which are hardly debuggable. It seems like ubuntu 10.04 has ltsp packages completely broken and abandoned. Have someone succeeded to install ltsp on 10.04 without hard brainfucking? Maybe it's better to install ltsp from scratch, or choose another distribution?

Ubuntu Servers :: Installing LTSP When Using A Separate DHCP And TFTP?
Mar 17, 2010I want to install Ubuntu LTSP on top of an already existing system. However, I want to use a different DHCP and TFTP server. Do I simply just install 'ltsp-server-standalone' with apt and run 'sudo ltsp-build-client', stop the DHCP and TFTP server and stop them from starting automatically? Would I then just copy over the pxelinux.cfg/default file from /var/lib/tftpboot along with the initrd.img and vmlinuz images to the TFTP server?
Edit: Do I need to actually copy the whole /var/lib/tftpboot/ltsp directory over to the TFTP server?
