CentOS 5 Hardware :: Where To Go To Find Laptop Hardware Compatibility Information
Dec 10, 2010
I want to put centOS on a laptop with the i7-640M processor. I'm trying to figure out before I purchase a laptop which laptop (if any) will work sufficiently well with centOS. The software I'll be running is only qualified on centOS.Where do I look to find such information?Specifically I'm considering the hp online configurable dv5t laptop with the i7-640M processor.
I'm planning to leave it in a closet most of the time and VNC over VPN to get to it.Digressing still further, the performance for a single threaded application as well as the price and power consumption for "always on" make it a good choice for a server applicaion... not to mention the battery backup in the event of power failure. It may not be designed to operate under high CPU load for extended periods of time so I my use external fans to improve ventilation around the unit or take other steps to mitigate a cooling deficiency.Digressing yet still further, yes I do need the performance of the i7 so lower power processors are not an option. I just really only need one or sometimes 2 cores at most making the 32nm i7-640M ideal.

I'm in computer sales and I have a customer that wants to replace all his macs and windows computers with ubuntu. I don't know anything about linux but I heard that there is a strong community behind ubuntu He's asked me to send him an evaluation unit so that he can test it out with ubuntu and see how well it works. I personally support his idea of going with reliable, bare minimum spec computers to do a whole overhaul. But I don't want him to deal with compatibility issues on a regular basis..I was looking at the Dell D620-D630, what are your thoughts on these machines running ubuntu?

I am looking into 1026TT-TF and 6016TT-TF for a CentOS 5.4 or 5.5 64bit installation:
SuperMicro 6016TT-TF
SuperMicro 1026TT-TF
It will be used as a Web-server mostly. Since they are twin nodes, one node will be one strong firewall. I have been checking all over and I can't find any driver, bios, or issues with this specific motherboard from Supermicro and Intel 5500/5600 series CPUs. Is there anything that would concern you with these servers?
I am also looking to put in a 4-port Gigabit LAN card into one node which I doubt makes any difference in the whole equation. Further more, and most importantly, the first one takes only 2.5" HDDs and the second option accepts 3.5" HDDs. Other than size availability and price, are there any concerns regarding performance when chosing one over the other? System which accepts 3.5" HDDs only takes two per node so I have to opt for 1TB drives. For the 2.5" system I can go with 4 of 2.5" HDDs of 500GB in size. Either of options selected will be setup in RAID-1.

I am trying to install some NVIDIA drivers on my machine. I went through the process and got this message:
Code: Select allWARNING: Unable to find a suitable destination to install 32-bit compatibility libraries. Your system may not be set up for 32-bit compatibility. 32-bit compatibility files will not be installed; if you wish to install them, re-run the installation and set a valid directory with the --compat32-libdir option. URL...Where in I ran this in the terminal to create the 32-bit document tree.
Code: Select allsudo apt-get install ia32-libs
E: Package 'ia32-libs' has no installation candidate.
I really just want to get these NVIDIA drivers up and running. I already installed and updated the headers to just be able to half-way install the drivers (the second monitor works now).

I have installed Centos 5.6 (32 bit) in a virtual machine and would like to know if it is possible to update it to a 64 bit installation (probably I will also need to move to another version of the vm player too) or if there is any kind of compatibility lib(s)

I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.

Is there a way to find out information about a process based on the command used to run it?
Ideally I would like to get processes ID %CPU and memory usage back. I have written a short shell script which does this but I wonderd was there a command that did this.
Here's my shell script
Code:
#!/bin/bash
ExpectedArgs=1
ARGS=$#
if [ $ARGS != $ExpectedArgs ]

Where can I find comprehensive information on optimizing Linux? I keep searching online but seem to get only to performance monitoring. I don't want to run a lighter version of Linux or upgrade my hardware! Just want to get my current distro and future ones I might install to run at its best.

When I try to hit my jsp pages all that gets displayed is the source code.I cannot find any log files that give me any information. It seems as though apache is not forwarding requests to tomcat6 but I cannot verify this. I need some direction on what is happening here. I'm lost and have run out of options.Would JAVA classpaths cause this type of behaviour if they are wrong?

The default Emacs on Mac OS X, 22.1, appears to have some problems with the info/help stuff.
When you hit C+h i, it says:
Can't find the Info directory node.
It works in AquaEmacs, but I downloaded the 23 version of emacs precompiled binaries from here and I still have the same problem.

Back in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and [URL]. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.
I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:
How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr" What kind of disk-partitioning operation can be performed non-destructively, and why ? What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk. There are many free partitioning tools out there, which one is safe to used ? NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.

I know there are similar topics about this that have been posted, but the information I need I cannot find. Im in a situation where I have two new HP DL360 G6 servers, both have a HP Smart Array B110i Sata Raid Controller. Since the raid controller is so new CentOS 5.3/5.4 and RHEL 5.3/5.4 do not have support built into the installer.I do have a driver for the raid controller which I have used and successfully installed CentOS 5.3 on one of the systems.The reason I need to customize an ISO is because I need the raid controller driver as part of the installation disc. As these systems are servers and are going to be deployed remotely I will not have physical access to these systems if they need to be rebuilt. I also have to build machines remotely as well using iLO (having a floppy image or usb image of the drivers does not work through iLO).
The installation rpm's can be as is, I do not need to make any changes there. I just need to make sure that the raid controller driver is loaded into memory from the media rather than another media source, before the installer kicks in.

I am trying to get my head around my new server. I am using CENTOS 5.4 x86_64 with 300GB harddrive.
The 300 GB been partitioned with the following:
Device Size Used Available Percent Used Mount Point
/dev/md0 99M 18M 77M 19% /boot
/dev/md1 16G 8.7G 5.8G 61% /
/dev/md2 246G 40G 194G 18% /home
/dev/md3 4.8G 1.6G 3.0G 35% /var
/usr/tmpDSK 3.9G 432M 3.3G 12% /tmp
I have increased teh tmpDSK as it was getting full very quickly. My question is, what are these md0; md1, md2 and md3 are they harddrive partitions and as md1 is getting full will that have an impact on my sites.

One of our devices running CentOS 5--an 8e6 Technologies Enterprise Reporter network appliance--has started displaying the following three messages repeatedly, though not continuously.Best as I can tell, hard drive four may be experiencing sector errors.(The messages do differ slightly at times. For example, 16384 may instead read 49152 or 12285, and the two strings of colon-separated hexadecimal digits may also vary in content.)Other than these messages, the device seems to be running fine. Its internal diagnostics indicate no problems.I will, of course, call 8e6 Techonologies tech support. But, prior to that, I'd like to do some troubleshooting on my own. What other troubleshooting techniques may I employ to gather more information?

When I attempt to add software i get the following error:
Unable to Retrieve Software Information
This could be caused by not having available connection.

To get my browser to work properly, I have to specify a proxy (manual) and use the IP address of our proxy server. After this, I'm able to get out through the internet
using my browser. Not sure why I fail to get software updates though. I used the same setting in Proxy - Control Center. Repository Manager show's CentOS-5 - Addons mirror list as :

I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.
Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data

I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:
> uname -rmi
2.6.18-53.el5 x86_64 x86_64
> grep eth0 /etc/modprobe.conf

i've configured my laptop so i can use my domain account (active directory win 2003 DC) to logon to my machine. Now i'd like to browse and mount shares etc using my logon information. Now when i connect to a share with nautilus it tells me 'guest' can't log in and i need to re-enter my user info. This is a real pain since our passwords change often. Is there some way i can use PAM to authenticate? I've searched everywhere, but you only find info about the other way round (win->linux).
