I have just installed Centos 5.4 on my box and run "yum update", but to my surprise it says there is nothing to be updated:

Setting up Update Process No Packages marked for Update test
Consider the following scenario: you have two disks that are kept synchronized by some method. Could be RAID, could be LVM snapshots, could be a script. However, something has gone wrong. The disks are out-of-sync and you don't know which disk received which updates. You want to manually re-sync the disks but how do you figure-out which file to copy where?
I'm thinking of saving recursive directory-listings of the entire disks to text-files. Sorting them on last-update and removing all identical entries from the files.
I have a feeling that this is something that can be done with just a few command's but I need some help to get me started.
My server started to throw the following errors at me:

I don't think none of the above gives deterministic answer. Since I have 32-bit & 64-bit different system all of above spit out the same info.
How do I determine which nVidia kernel to use with my system? I'm running a GeForce9800GT
View 11 Replies View RelatedI was wondering how can I determine among the modules loaded at boot which of them are really necessary and which are not, in order to reduce the boot process time and have a more "elegant" system start.
I know this theme is a little bit of complicated because it depends of the user's point of view and demand a high knowledge of which things are happening in your system but I need somewhere to start improving the performance of my debian system.
I have installed Arch Linux quite a few weeks ago; but I'm still trying my best to install the nividia display driver for my graphics card (nVidia Geforce 2 MX 400). Not only in Arch but have tried installing on other distros and still failed. I have read up all the documentations and I still find it hard to do this task. When I used the terminal and executed the NVIDIA-Linux-x86-94.43.01-pkg1.run file without any window manager running, I get this problem:
ERROR: Unable to determine the version of the kernel sources located in '/lib/modules/2.6.35-ARCH/build'. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option.
ERROR: Installation has failed. Please see the file '/var/log/nvidia-installer.log' for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at nvidia.com.
Now I'm using Arch Linux Kernel 2.6.35 and I have got the source. But where am I suppose to put it now? I do not want to change the kernel. I just want the nVidia installer to identify that there is a kernel source so that it can install. I have searched up a lot on websites and ended up with no proper guide.
This is a very old driver. So since now I have the nVidia driver installation package and also the kernel source,

View 2 Replies View RelatedI have recently graduated from uni and during my time there I have developed an interest in HDL, specifically Verilog. As my current job doesn't lend itself to doing anything in verilog so I decided to keep myself sharp by designing a 32 bit processor that is similar to (but not the same as) the MIPS processor it will certainly be RISC. While starting work on it I have decided to start a blog detailing what I have done including the source file as I am entering my work into the wide world I think it needs a licence but I am not looking to make any money or even to derive any fame from what I'm doing. Like I said the main reason to do it is to keep me active in using HDLs.
I hope to gain from the blog suggestions for alternative(better) ways to do what I am doing, for people to use what I have done as an example of a medium sized project in verilog and to force me to have some form of documentation on my project. That's enough self publication to the question. Is the GPL (either version 2 or 3) applicable to work in HDL as it is not a traditional programming language but shares many of the same features? It certainly does not feel like I should use a CC license. I'm not sure this is the correct forum for this question but it seems most applicable.
I wrote this little function that I use from my '~/.bashrc' (from a script I also made, with help) to run a program on a timer, however there is one small issue I'm having.
Code:
##### Run program on a timer
# Usage: program-timer <program> <runlength (in secs)>
function program-timer()
{
$1 &
mypid=`eval ps ax|grep "$1"|grep -iv "grep"| awk '{print $1}'`
[Code]...
Basically, it works just fine, but the issue I'd love to get help with is when the timer runs out, it doesn't shutdown the program. That is, not until I close gnome-terminal. I've tried 'exit' in several places, but it doesn't seem to close it.
Now, the above script does what I want, but using 'killall gnome-terminal' not only closes the gnome-terminal window I am running the function on, but ALL gnome-terminal windows I may have open.
Does anybody see a simple way to fix my small dilemma, to have it close only the gnome-terminal window I'm running the function on?
After spending many frustrating hours, I finally found a solution to easily re-mux m2ts/mts files produced by Sony HDR-SR12 or other similar camcoders in order to stream them smoothly over DLNA to Samsung C-Series (55C8000) TV in full HD quality. But the solution is generic and can be used for any rendered.
First the problem: Above mentioned Sony camcoder produces 1920x1080, 60i video. However, the time-stamps on the frames in each interlaced field are wrong, both frames of a filed having same time-stamp. This is very problematic for almost all rendering devices. My first approach was to re-encode these mts files using Handbrake to convert to m4v. This worked though at a heavy computing cost. The conversion is very intensive and for 50GB of videos could easily take more than 12 hours on a core-2 processor.
One day, I was browsing Ubuntu forums, I came across this thread. This actually produced the re-muxed file in a fraction of a second as opposed to re-encoding with Handbrake that took very long time.
1. It is using mencoder + lavf, a known broken combination in presence of B-frames.
2. It does not allow to copy the subtitle track (PGS) that Sony camcoder produces. This subtitle track is very important as it contains the recording date/time information which will be valuable when using these videos in future.
The following solution overcomes all the above-mentioned problems, is rock-stable and preserves the sub-title stream as well. I use ffmpeg to simply copy all the streams and output them in an mkv container. No information is lost/re-encoded. Here is the simple answer (as often observed in scientific research, the useful answer to a complex problem can often be stated very simply ):
Code:
ffmpeg -i input.mt2s -scodec copy -acodec copy -vcodec copy -f matroska input.mkv I have written a script that converts all the m2ts files in a subfolder to mkv. The script is as below:
Code:
#!/bin/bash
# m2tstomkv_subs (Fix the faulty fps (dual frames in the interlaced fields with same time-stamps) and repackage in matroska mkv container)
time {
[code]...
The conversion is lightening fast. Finally I am able to watch the videos in their true quality.
the best repo. of them all which includes all the software needed.?ans is there any repo which allow latest softwares in centos like fedora.????cause i don't want to install all repos.in centos 5.5.
View 1 Replies View RelatedAfter doing an update a couple of days ago (had previously upgraded to 5.6), the font size in firefox (file forward reload, etc), terminal and the panel (using xfce) are significately smaller. Searching the web, mail lists and the forums have not resulted in finding anyone else with this problem. I did notice that glibc has a bug that is currently being worked on at Redhat but it is unclear if the font problem I am seeing is related. Note also, that the initial upgrade to Centos 5.6 was successful.

'Determining IP information for eth0... failed; no link present.'

I am running a CentOS 5.6 32 bit installation under VMWare ESXi and have been experiencing some very high load values from time to time. The server is running multiple installations of gameservers, and the load fluctuates from around 1 to 9, with more or less the same amount of players playing (give or take 5-10 of a possible 80). I've been running DStat with almost all possible metrics, and, except for the large fluctuations in load, nothing else out of the ordinary seems to happen when load is rising. (Log data can be provided, if anyone wants to see it). Disk IO, Network throughput, memory consumption, CPU usage, process count, all stay at the same levels when the load is 1 as when it is 9. How I can begin to troubleshoot this, and find out why the load goes to such high values?
View 1 Replies View RelatedSince an Aptitude upgrade to my Debian Squeeze operating system (using video driver NVIDIA-Linux-x86-195.36.24) some weeks ago, which installed linux kernel 2.6-32-5-686, grub has been giving me two boot options (in addition to MS Windows). I expect that this is quite normal so far ...
However, if I try to boot using this new kernel, rather than kernel 2.6-32-3-686, I can only get the command line interface. Everything seems to work after boot with the new kernel, except (although the system seems to load kdm successfully) I cannot start X. Booting with the old kernel still takes me to the desktop as normal (I've set KDE to automatically bypass kdm, as I'm the only user of this standalone PC), and because of this I've been slow to address the issue with kernel 2.6-32-5-686, but since the problem doesn't seem to be going away with more recent upgrades, I suppose a request to the forum is the only way to go:
So, is the problem I'm having the same as was addressed in this thread? If not, would I only need to reinstall the same NVIDIA video driver so that it recognises the new kernel? If not, would installing NVIDIA-Linux-x86-256.35 solve the problem, and would I have to deinstall the old video driver first? Finally, if and when I solve the problem, can I safely deinstall the old 2.6-32-3-68 kernel?

View 5 Replies View RelatedI've noticed a bad behaviour with the latest 2 Fedora kernel releases:
- it happens with 2.6.31.12-174.2.19.fc12.x86_64 and 2.6.31.12-174.2.3.fc12.x86_64
- but 2.6.31.9-174.fc12.x86_64 is OK
The problem is as follows: Any kind of terminal application (any X based terminal and the console itself) hangs on certain operations involving colors from what I've seen
E.g. 'ls -F --color' as predefined in Fedora works but 'ls -F --color -a' hangs. Midnight Commander also hangs but works on black and white.
My terminal is xterm-256color under X and linux under console.
Other observations:
- it happens on a AMD machine but not on an Intel i.e. not all hardware is affected (couldn't narrow it more)
- same machine, same software stack but with kernel 2.6.31.9-174.fc12.x86_64 works OK

Is this the latest version. i don't know how old 11.4 is, but there weren't a great deal of updates. have added a few repos like packman etc.
Kept /home as the same and what a difference that made. i used to do a fresh install every time, it saved just about all my settings!!! just needed a few more programs and stuff but nothing major.
Really quick, clean install. just need to delete my old root partition for the old 11.3 system.
Would also just like to know are there many differences between 11.3 and 11.4?
I reported a bug at [URL].., then I had been asked to test the latest generic kernel in order to test whether the bug exist in latest kernel or not. I had read the information at [URL]...

Then, I restart my computer by turning off and on again, select the older kernel, successfully boot into Ubuntu to post this thread. What can I do since I am required to test the latest generic kernel?
