If I was to set up a Cluster, I know it wouldn't make much difference to loading up my browser, but would all heavy duty programs (Video Encoders mainly) work with it, or would I need to use programs specifically designed for cluster use?
View 1 RepliesI'm planning on setting up a server cluster specifically for 3D video rendering. In order to maximize speed I wanna use OpenGL hardware acceleration for that and I'm pretty sure that I have to use an NVIDIA video card if I want the whole thing working reliably. Will I be able to start an X-Server with GLX on an NVIDIA video card that doesn't have a monitor connected to it? And what will be the maximum "virtual" display resolution that I can use?
Since I wanna have several servers running side-by-side I really don't have the room for any monitors.Just to avoid misunderstandings: It is not my intention to show what's being rendered to anyone in real time. I will only create video files that can be downloaded later. I'm already pretty sure that this will work, probably using "CustomEDID" or something like that, but I don't have a suitable setup available to test it right now.
Does linux kernel 2.6 support suid & guid?. I just read somewhere that "latest linux kernels does not support suid & guid as it can pose a security risk if the setuid attribute is assigned to executable programs that are not carefully designed". I need a confirmation about what I say is correct or if not please correct me.

Is there some secret syntax I could put in the exceptions to the effect of "all and not firefox" (as in, make all programs an exception, except Firefox)?
I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.
View 9 Replies View RelatedI'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :
[Code]...
And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.
configure a separate NIC for the heartbeat. what i need to add to cluster.conf to achieve this?
View 1 Replies View RelatedUsing CentOS 5.5. I have ssh setup to use a radius server for authentication. When I use filezilla to test sftp I can successfully authenticate and get directory listings, but every time I try to download or upload a file filezilla attempts to re-authenticate which fails because the radius server uses token auth with one time passwords, so the original password used to authenticate is no longer valid. However I can browse directories all I want and it never tries to re-authenticate.
1. is this re-auth just how sftp protocol was designed? like re-auth anytime a user tries a different action, like browse vs download vs upload?
2. or am I just missing something? (very likely, I'm not real experienced with linux)
Which is why I'm glad KDE still values the good old desktop paradigm. I'd like to use unity, but unfortunately, it is impossible to customise in any significant fashion. I will be switching to Kubuntu now. I think a "start bar" is the perfect mouse & keyboard GUI paradigm.
My recomendation to the Ubuntu devs is to give unity an option to replace the awkward (for a mouse) application finder with a "start menu", and also give an option to have the old style of task bar as well.
I am not complaining here. like I said, I like KDE and have no problem switching over. The only reason I care about unity is; I don't want somebody to try Ubuntu, find out you can't customise the GUI at all, then go right back over to windows or OSX.
I am writing a script that is designed to verify an application is running. The if...else statement in question is the following:
Code:
# Check if <application> is running.
ps -ef |grep <application> > /dev/null
RC=$?
echo $RC
[Code]....
I have started testing by disabling the application in question, and then running the script. The problem that I am seeing is that even though the application is not running, I am getting an output code of 0 due to the successful running of the ps command. What syntax change(s) do I need to make in order to accurately determine when the application is not running?
I want to be able to connect these machines to the domain and use active directory on them.

I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...
The Preferred Applications applet doesn't do what I need it to do.
What I'm looking for is a Win 3.x style File Association applet or config file so I can have .mp3's handled by Audacious and .m3u's handled by VLC, and so on. I'm sure it's out there somewhere, but I can't find it.
I mainly do c/c++ development in linux...also i sometimes use java and i would really like it if i had mono also.. so i am pretty much looking for support for all major languages with ides...can u suggest me a distribution?

View 9 Replies View RelatedI'm really new to Ubuntu, and am running 10.04. Anyway, I accidentally got rid of the Evolution icon in my Notification Area. Every time I try to put an icon in that section, it will not let me, and makes me put the icon on the left side of it, like on the main part of the panel. I do not know if I just hid the icon, or if I actually removed it, and I am sure the fix is really simple, I just can't seem to figure out how to do it. Also, I opened the Universal Access program when checking out all the cool things in my new OS, but I can't figure out how to hide that icon.
So if you could tell me how to unhide Evolution and hide Universal Access, in the Notification Area, that would be awesome.

View 1 Replies View RelatedI have successfully installed a Ubuntu chroot (Maverick) on a running Linux appliance (an old Thecus N5200PRO box) which has been running various services for me quite happily.
When I attempted to add a webcam (for snapshotting) to this mix, I've come up against a problem. Since the chroot by default uses the kernel of the Thecus appliance, there appears to (understandably) be no support for the Logitech UVC webcam in the appliances' kernel; consequently inside or outside the chroot I can't access the UVC webcam.
I think I can get around this in a simple way if I can run a standard Ubuntu Maverick 32-bit kernel in the chroot.
Does anyone know how to chroot with alternative kernels, or quite simply, how to get a UVC webcam accessible on a Thecus N5200PRO?

Is there a Linux competitor for Zune and iPod out there? - any portable media or mp3 player that is specifically made for or by Linux? I know there are enough players that simply play mp3s off a flash memory and are therefore compatible with any OS but I am rather looking for something like Zune or iPod - doesn't have to be with touch screen but with some library interface and easy synchronisation options.

View 2 Replies View RelatedOur Apache server is pretty much configured straight out of the box, and I've noticed it is using far more CPU and less memory than another server where I have the following:

The Apache documentation says that if these aren't set, the values are obtain from the OS. How can you tell what those are? I'd like to see if I can tune Apache's performance, but I don't even know if these values are higher or lower than what it's currently using...

View 14 Replies View RelatedI've looked all over the web, but don't see an answer to my particular case. I'm in GParted in Ubuntu Live CD 9.10 amdx64 To prep for Ubuntu install, I'm attempting to resize and re-partition my second hard drive which was FORMERLY my primary boot drive for Vista before it crashed a few days back. It is CURRENTLY my Vista User data file and is about 250Gb in size. The drive is a SATA 500Gb total.
But GParted now all of a sudden gives me several "Cluster accounting failed at blah blah: missing cluster in $Bitmap" error messages. Is there a good way to 'fix' these errors? (besides reformatting it) I deleted the long-winded background, so let me know if you need more info. Short version: I installed vista by reformatting my 120Gb data drive as the primary master now. Then I plugged in my 'previous' 500Gb Sata drive, and pointed Window's User folder to my old User folder, and voila, was back up and running in Vista... minus all my programs. but now, both drives are recognized by GParted as "boot" drives.
