Thinkmate is opteron, and the Dell, xeon -- which some would say is a factor in Dell's favor; Dell includes a RH subscription whether you want it or not; Dell has three hard drives (the max), Thinkmate four. With the Dell, the memory comes from Crucial, which means there's a waste of two small modules; Thinkmate sells memory at a reasonable price (I'm figuring 32 gigs). The HP xw9400 is closer to the Thinkmate, but an extra $200 to $300, with memory from Crucial. I'm just leery of a maker that I don't know; I searched for reviews and comments, but found almost nothing. Maybe that's telling me something. Barry

Problems making custom isolinux.cfg
by treed＠ultraviolet.org 04 Sep '08

04 Sep '08

I have added a few custom RPM's to my CentOS 5.2 CD, dropped a kickstart.cfg file in the root of the CD, and now want to change the isolinux.cfg in the boot.iso so that it will automatically do a kickstart install when the CD boots up. I am using buildinstall to make the ISO. I edited the isolinux.cfg in /isolinux in my CentOS 5.2 distribution tree off of which I am building my ISO. But after buildinstall runs the isolinux.cfg is changed back! Where is it getting the original from? Where should I be changing it to get my modified isolinux.cfg into my cd? Just to get around the isolinux.cfg issue manually I tried booting and at the prompt I say: linux ks=cdrom:/kickstart.cfg But it says that it cannot find the kickstart.cfg file. Is it expecting it in the root of the boot.iso or of the CD? I put it in the root of the CD. I can mount the CD and see that it is there. I can't figure out how to put it in the root of the boot.iso (if it even needs to go there) because apparently that is getting remade by the buildinstall also and I'm not sure where it is getting the contents from. Here is the entire process I use for building and burning the ISO: /usr/lib/anaconda-runtime/buildinstall --version 5 --product CentOS --comps /var/www/html/centos/5.2/os/x86_64/repodata/comps.xml --release MyCentOS-5 --prodpath CentOS /var/www/html/centos/5.2/os/x86_64 mkisofs -R -J -T -r -l -d -allow-multidot -allow-leading-dots -no-bak -o /var/www/html/centos/5.2/isos/MyCentOS-5.2-x86_64.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /var/www/html/centos/5.2/os/x86_64/ cdrecord blank=fast -dev=/dev/sg1 -v -eject /var/www/html/centos/5.2/isos/MyCentOS-5.2-x86_64.iso Any help would be greatly appreciated! -- Tracy Reed http://tracyreed.org

OT: workstation recommends: Thinkmate?
by Barry Olddog 04 Sep '08

04 Sep '08

I'm looking to buy a new workstation, and it looks like Thinkmate makes what I need -- their vsx "virtually silent" variety. I hestitate because I wasn't happy with a laptop I bought a few years ago from a small outfit that sold Linux boxes exclusively. Does anyone have experience with Thinkmate, and in particular, the VSX line? If the later, is it really quiet. I run Centos on four machines now, three of which are Dells, and I'm hoping to do better. The Dell T5400 is close to what I want, but I get more for less from Thinkpad -- at least on paper. thx, Barry

kickstart problems
by Paolo Supino 04 Sep '08

04 Sep '08

Hi I'm having a problem with setting up a kickstart environment based on CentOS 5.2 x86_64, on a Sun X2200 M2 server (both the server and the client in the kickstart environment are Sun X2200 M2 systems): the first attempt to load stage2.img fails with the error screen: "unable to retrieve http://192.168.11.10/source/images/stage2.img". Pressing the "OK" button brings up the "HTTP Setup" screen with "Website name: 192.168.11.10" and "CentOS directory: /source" if I press OK it successfully loads stage2.img file and continues with the kickstart installation to a successful completion. I checked the apache logs on 192.168.11.10 and there is no attempt by the client to even load stage2.img before it prompts for the error. Has anyone encounter this problem and has a solution for it? -- ttyl Paolo

Re: [CentOS] OT: Migration from Evolution to Thunderbird (Thunderbird mbox files)

With the Evolution MUA, also using IMAP on gmail.com the mbox files are easily seen. in .evolution I suspect that I should post on a Thunderbird mailing list and ask where the mbox files are located on my Desktop, or, if using IMAP, as I am, there are no mbox files on my Desktop. Probably it's one or the other.

That is, you can access a device present at start up but it's not swappable. Given: [dave@bend ~]# lsusb Bus 001 Device 002: ID 154b:0005 PNY Bus 001 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 you can attach the device to a W2K qemu session by starting qemu with something like: qemu -usb -usbdevice tablet -hda w2k.img -usbdevice host:001.002 -m 256 -localtime & I tried swapping two different 1GB thumb drives and the content of the drive wasn't visible after the swap. If you decide to go the qemu route for a VM with W2K, I wrote about the problems I ran into on my blog at: http://davenjudy.org/wordpress/?p=29 Getting a basic W2K VM working was fairly easy but getting it fully updated was a real pain. I still have a couple of MS updates that I can't apply since W2K stops working if I do. Cheers, Dave -- Politics, n. Strife of interests masquerading as a contest of principles. -- Ambrose Bierce

VMWare Server doesn't like new CentOS installation?
by MHR 04 Sep '08

04 Sep '08

I just got a nice, shiny new machine at work, a Core 2 Duo, on which I just finished installing CentOS 5.2 with a fair number of packages, SeaMonkey 1.1.10, Adobe Reader 8.0, Adobe Flash 9.0, mplayer, mplayerplug-in (both from rpmforge), and I think that was it. Then I went and got the latest VMWare Server, 1.0.7, from VMWare, pulled down their rpm, installed it, and ran vmware-config.pl, which is what I have to do (at home) after every new kernel install, too. Except, this time it failed: Extracting the sources of the vmnet module. Building the vmnet module. Using 2.6.x kernel build system. make: Entering directory `/tmp/vmware-config0/vmnet-only' make -C /lib/modules/2.6.18-92.1.10.el5/build/include/..

Remember to use this port when connecting to this server. Unable to find any instance of the super-server "inetd" or "xinetd".

If you do have "inetd" or "xinetd" installed, make sure that /etc/inetd.conf or /etc/xinetd.d exists. The configuration will continue, but you should re-run /usr/bin/vmware-config.pl after you fix the super-server. Hit enter to continue. ----- I checked, and I am running xinetd, there _is_ an /etc/xinetd.d, and I have no idea what is causing this. I even went back, removed the 1.0.7 server and installed the 1.0.6 server, which I think is that last one I installed at home, and that got the same error (actually, the above is from the 1.0.6 install). My new h/w: Intel Core 2 Duo E6750 2.66GHz, 2GB 667MHz DDR2 RAM, 160GB hard drive, nvidia ge7300fs video card, not sure what mobo, but I can't help but wonder if that has anything to do with it (does it???). Running CentOS 5.2 32-bit with all the latest updates. Anyone know anything about this? I asked in the VMWare forums, but haven't got an answer yet (in fact, I rarely get answers there...). Thanks. mhr
