It would take me about 2-3 additional hours, to reinstall CentOS5 and restore everything. Installing Windows and it's applications it *VERY* time consuming. But, if I dont redo my CentOS installation, I won't have room for VMware Server. I won't have time to do this for 2 or 3 days, so I still have time to decide on the path to take. :-) Minimum, I will wipe MS Windows and install it with the new English language CD I got from Dell last week. >You could also use Xen in CentOS 5 for your Windows virtualization. I'd wait for 5.1 though which will be more refined then version 5. Does Xen require a special CPU or motherboard? Thanks much, for all of your ideas! Lanny

ntp queries not being answered
by Engineer, Gaurav 20 Nov '07

20 Nov '07

Hello All, My name is Gaurav, and I am tasked with configuring a linux box with NTP. I am having a problem that I hope you can help me with. We have installed CentOS V5 on 1 processor down in the lab. The rest of the processors on the network are AIX boxes versions 3.2.5 and 5.2. I worked through the entire initial NTP configuration; setup the /etc/ntp.conf file to point to the server, etc. Now when I run the ntpdate -d <address of server> on the linux box I get all the right information. Also, when I run the same command with the address for another non-linux box (AIX): ntpdate -d <address of non-linux box> I get all the right information again. The problem is that the linux box does not answer queries of the command to it. So if I enter the following on the non-linux box: Ntpdate -d <address of linux box>... all the values for offset, etc. are all zeroed out. So the linux box is not passing any information back to the querying processor, even though the command works the other way (executed on the linux box querying the non-linux box). Also, I don't see the usual "transmit....recieve" pattern for the command.... just the "transmit...transmit...". Are there any reasons that the box can query the server and other boxes successfully, but not answer queries sent to it? And in an effort to troubleshoot, I have commented out everything in the /etc/ntp.conf file except the server address to see if there was something in that file causing the problems, but that didn't work either. Do you have any information on this that could help me? Anything at all would be appreciated. -thanks.

Xen and multiple block devices
by Francois Caen 20 Nov '07

20 Nov '07

Hello, CentOS 5.0 on x86_64 I'm trying to set up Xen paravirt guests with access to 2 block devices: One for / and one for swap. The block devices are LVM LVs, but that shouldn't matter. When I create the guest using either virt-manager or virt-install, I get asked which device to use for xvda. But I want more block devices: xvdb for swap. I know how to add this as an option to the config file in /etc/xen 'phy:/dev/vg1/guest1-swap,xvdb,w' But that file only appears AFTER running the installer. How do I make xvdb visible DURING the install of CentOS? Thanks, -- Francois Caen

Re: [CentOS] Dual boot box: WinXP & CentOS 5: Impossible torestoreWinXP?

I wouldn't necessarily wipe the whole HD, just the windows partition. You could also use Xen in CentOS 5 for your Windows virtualization. I'd wait for 5.1 though which will be more refined then version 5. I've been thinking of setting up a Xen machine of my own with a Windows HVM and a couple of Linux PVMs with their GUIs/consoles pinned to different virtual consoles. It has always been a dream to Alt-FX to the OS of my choice. I'll need more then 1GB of RAM to do it right though. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS Mailing List <centos(a)centos.org> Sent: Mon Nov 19 18:18:28 2007 Subject: Re: [CentOS] Dual boot box: WinXP & CentOS 5: Impossible torestoreWinXP?

I recovered the data from the NTFS partition this morning, so I am ready to "learn by destroying". The consensus of opinion from Ross and you is that I should bite the bullet and do it correctly. Wipe the HD and do fresh installs. Time consuming it will be (especially installing the Windows aps), but, I will have a better system and I will learn. For several months, I've wanted to install/use the free VMware Server, but I don't have space on the HD to do much with it now. One of the suggestions, from Alain, was to have WinXP running virtually, under CentOS. I am contemplating devoting about 75% of the HD capacity to CentOS. Installing a lean WinXP in English, and dual boot with CentOS, and then install VMware Server and install WinXP in English, in virtualization. The "KISS" technique (fdisk /mbr, run the anti root kit program, reinstall GRUB and restore grub.conf) is tempting and would probably work, and would be much faster, but I still wouldn't have the kind of system I will have with the more time consuming approach. All the ideas everyone who has responded to this thread have thrown into the basket for consideration are deeply appreciated!

Question: What would you suggest I run? Suggestions are most welcome and solicited! BTW, the system has been shut down and rebooted a bunch of times (in Linux) since the Trojan Horse hit. I have the AVG Free anti virus program running in Windows and it told me about the Trojan Horse and that the user32.dll file was damaged. It's possible that because the box is Spanish in Windows, I clicked incorrectly and made this problem much worse, but I'm not sure of that. > I would run all Windows accounts as restricted users from now on. I'll try to figure out how to do that in WinXP. I won the box in a raffle and it has WinXP in Spanish, which is not my native language. If I need to reinstall everything (I believe I can avoid that, with the suggestions you and others on this mailing list have made), Dell sent me an English language WinXP CD, last week, and I'll install in English, if it comes to that. All of your comments and suggestions are greatly appreciated! I am beginning to *hate* MS Windows, but there are still a few things we use it for. Lanny

Hi, I've installed CentOS 5 on a Dell pe1950 with 2 dual port NICS. One of the NIC is an Intel and use the e1000 module. The problem is when the server is rebooted it does no asign the ethx name to the NICs, instead the so assign something like _dev377362... so i dont have networking on the server. Any ideas what is happening and how to solve it? Thanks.

Patricio, I had a very similar issue with a wireless Intel device coming up as _tmp29384792. I found that if I did a service network stop and removed the kernel module, loaded the kernel module and then service network start, everything went back to normal. I have not bothered to see why it loads this way, as its only every few boots on my personal laptop. If I remember correctly people noted the hardware timeout before it completed loading, but this is just a guess as to what it was as I never confirmed any comments people had made. This isn’t a solution obviously to the issue, but does give you some steps to see if the devices can be reloaded and work or not.
