Hello all! Actually I use dual boot PC with CentOS4 (kernel 2.6.9-11) and WinXP (HDD 20GB, 512MB, PentiumIII 800MHz), but I have the following problem doing the image with g4u ----BEGIN ERROR MESSAGGE---- wd0: (uncorrectable data error) 8951MB 1.59MB/s wd0d: error reading fsbn 18333440 of 18333440 - 18333567 (wd0 bn 18333440; cn 18187 tn 14 sn 62) retrying wd0: (uncorrectable data error) 8951MB 1.59MB/s wd0d: error reading fsbn 18333440 of 18333440 - 18333567 (wd0 bn 18333440; cn 18187 tn 15 sn 52) retrying ----END ERROR MESSAGGE---- I review the HDD partition with the g4u command "parts" g4u>parts wd0 Found NTFS partition; size 20482812 (10001MB), offset 63 skipping existing NTFS partition at slot e Found Linux EXT2 partition; size 192780 (94MB), offset 20482875 skipping existing Linux EXT2 partition at slot f Found swap partition; size 2040255 (996MB), offset 20675655 skipping existing swap partition at slot g Found Linux EXT2 partition; size 17157357 18377 (94MB), offset 22715973 skipping existing Linux EXT2 partition at slot i 9 partition # size offset fstype [fsize bsize cpg/sgs] d: 39876480 0 unused 0 0 #(cyl . 0-39559) e: 20482812 63 NTFS #(cyl . 0*-20320*) f: 192780 20482875 Linux Ext2 0 0 #(cyl. 20320*-20511*) g: 2040255 20675655 swap #(cyl . 20511*-22535*) i: 17157357 22715973 Linux Ext2 0 0 #(cyl . 22535*-39556*) I'm not sure about the mean of d partition.

SiL311x SataRaid (sata_sil)
by Dag Wieers 18 Jun '05

18 Jun '05

Hi, On my x86_64 system I have a SiL311x controller that can do RAID. If I configure my 2 identical disks in a RAID1 setup, I would expect to see only 1 block device on Linux. Still I see 2 block devices. Is this intentional, and if so, isn't that dangerous ? (i.e. writing to both disks at the same time) Anyone with an insight, please explain :) -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power]

Does anyone know of any programs capable of fine tuning my screen display settings? I'm using the NVIDIA drivers, and everything is slightly blurry - regardless of how much (or little) I set anti-aliasing to.

Re: screen fonts -- LCD and Analog Connections ...

Ryan wrote: > I did, 1024x768. > Sorry, analog Matthew Miller wrote: > Maybe the problem is just in that adjustment, then. Yes. You need to have your signaling _exact_ when dealing with LCDs. Some are very good at taking the timings of VESA standards. But some support some eccentric Windows timings that are _not_ the exact same as VESA. Or maybe you have configured your monitor for X with bandwidths that exceed the typical VESA modelines. E.g., did you upgrade from a CRT and just leave your X configuration intact? If so, then you might be sending 70, 72, 75 or 85Hz modes for 1024x768. And even though your LCD might support that analog signaling, it's not as ideal as using the VESA standard modes (typically 60Hz for 1024x768 on a LCD). You need to open up your LCD user's manual, find the resolution you want, and input the _exact_ 1) Bandwidth 2) Horizonal Sync and 3) Vertical Sync for that mode into a modeline calculator. Then put those modelines into your XF86Config/xorg.conf. Otherwise, at 1024x768, you're going to see a lot of the distortions. It has nothing to do with fonts. Ideally you should be using DVI and not an analog connector. That removes the problem entirely. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Thank you all for the advice. I had cygwin installed many years ago but that machine has gone the way of all silicon. While not terribly involved it seems overkill for the present need, which is just to run a single x-windowed application on a very occassional basis. I will look into the rest of the proposed solutions this weekend. Regards, Jim -- *** e-mail is not a secure channel *** mailto:byrnejb.<token>@harte-lyne.ca James B.

X-Windows client for MS-Win2K
by James B. Byrne 17 Jun '05

17 Jun '05

An intermittent need to connect to a CentOS4 development box from a MS-Win2K workstation using X-Windows has developed here. However, I cannot seem to find a cheap (read free) X-windows client for MS- Windows to accommodate this. This seems very odd to me, displaying no doubt my profound ignorance of the issues involved. The few shareware versions that I have located expect registration fees in the $90-100 range, which is something I have never encountered before. Is there a free X-Windows client for Microsoft OS's? Why is this software so rare and dear? Regards, Jim -- *** e-mail is not a secure channel *** mailto:byrnejb.<token>@harte-lyne.ca James B.

OpenSSL on CentOS 3.4?
by Peter Loron 17 Jun '05

17 Jun '05

I'm running a CentOS 3.4 box. According to yum, the OpenSSL 0.9.7a-33.15 package I have installed is the latest available. A check of the OpenSSL website shows 0.9.7g source being the latest. Is the CentOS 0.9.7a package patched to cover the same isues that the generic 0.9.7 source covers? If not, what's my recourse? Build it by hand? If I need to build it, has anybody crossed that bridge? Thanks. -Pete

This is a newly installed server running CentOS 4 with all current updates. It's been cruising nicely since installation a week ago until this morning. Then everyting started timing out and the attached messages appeared in the log (this is a short and sanitized extract). Load went sky high. Had to reboot to restore service and all looks happy again now, but if anyone can provide some input on these messages... TIA Brian

Serial Console + VGA Console
by Gerald Waugh 17 Jun '05

17 Jun '05

Hi, Trying to get vga console and a serial console to both work. I can get either one to fully work but not both. When using serial, I do still get a login prompt on the vga, But not all the boot up output. Seems like half to the vga and the rest to the serial port I added lines to /etc/inittab # console port T0:12345:respawn:/sbin/agetty -L ttyS0 115200 And added to /etc/lilo.conf append="console=tty0 console=ttyS0,115200n8" I tried to add to "serial=0,115200n8" lilo.conf, but this gives error unsoported baud rate, commenting the line out seems to work. Any ideas on how to get both VGA and serial console to fully work? Maybe, I can have one but not the other? Gerald

turning off prelinking?
by alex＠milivojevic.org 16 Jun '05

16 Jun '05

In short, the reason considering (and still only considering) turning it off is to make tripwire usable again (security vs. performance, I guess). Is it possible to completely turn it off system-wide? Any additional steps needed on the existing system (that already have half of the binaries prelinked)? What order of performance degradation to expect? If it is minor, nobody is going to cry about it. My old RH 7.3 systems don't have prelinking, and I don't see them being any slower than FC2 and newer systems that have prelinking... ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Big trouble: can't start server after new kernel
by Mário Gamito 16 Jun '05

16 Jun '05

Hi, I have this file server with CentOS 4.0 Each time a new kernel comes out, i have to recompile it, becuse i need Appletalk support and the kernel doesn't have it. I've done this before many times and in other servers, and all went well. Now, in this particular server, with the new 2.6.9-11, after i've recompiled it, created the .img and edited grub, the machine doesn't start at all. It says it can't find the kernel image. I cannot even boot with older kernels. To worsten things, i have LVM, so "linux rescue" tells me there's no Linux installation in the server and leaves me with a prompt. Now, i can mount /boot because it is outside the LVM, but when i do it, i lost access to any command, even a mere ls. Tried to pre-copy vi before the /boot mount and could access /boot/grub/menu.lst Everything seems fine, the files are all in /boot ...!!! Do i need to run grub command after editing menu.lst ? Never did that. And why can't i boot from older kernels ? Now, the really nasty thing: somehow, i don't have the smallest hint, i had a 500 GB external USB disk to make the backups, and the "linux rescue" erased it :( :( :( Bogles me!!! Please help me. This one can cost me the job. Loosing 300 GB of files from ~ 100 users on the file server is unforgiven. Any help would be apreciated. Warm Regards, Mário Gamito

CentOS 4.1
by alex＠milivojevic.org 16 Jun '05

16 Jun '05

Question about differences in RHEL 4.1 and CentOS 4.1 organization. Does CentOS follows same organization as RHEL? I don't see separate directory for 4.1 on Red Hat's ftp server (well, the public part of it, with SRPM packages), seems like all the updates were simply dumped into the 4.0 updates area, so basically doing normal system upgrade will bump all RHEL 4.0 systems to 4.1. On the other hand, on CentOS site, there is a separate directory for 4.1, with distinct set of packages for 4.1 that are not present in 4.0 update area. So basically, one would need to manually point yum to 4.1 directory tree to fully update system with latest bug fixes. Is this difference in approach intentional? Or the acutal update process (for those with RHEL subscriptions) is actually like the one for CentOS? How do you determine what packages were "regular" updates, and which packages were part of U1? ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

From: centos(a)911networks.com > Hi, > I have just installed 4.1 on a new Dell Latitude d610. It does > not automount the CDs. When I mount the CD manually I get: > $mount /media/cdrecorder > mount: block device /dev/hdc is write-protected, mounting read-only First off, there is a multitude of understanding that is required. Most consumers are not aware of many differences between CD-R v. CD-RW access, CD-R v. CD-RW filesystems, etc... In Windows, some of this is hidden from you to a point, but not all. E.g., you use a program to "record" whereas you directly access the drive letter to to "read/write." Windows only lets you "record" to CD-R (or CD-RW emulating CD-R), and won't "read/write" to anything but CD-RW (with a non-ISO9660 fs). These two processes are actually _different_. What type of CD did you insert? A CD-RW? CD-R? Or CD-ROM? Also note that CDs are not "formatted read/write" with ISO9660. ISO9660 is a linear, byte-by-byte track, that is not modifyable (most specifically, data is a "Yellow Book" track of ISO9660). You have to use _another_ filesystem to have "read/write." UDF is its replacement, although almost any filesystem can be used. As I said, a multitude of understanding. > The CD writer is an Philips IDE: CDRW/DVD-ROM CDD5263 There is some "read/write" support for CD-RW in kernel 2.6. I haven't messed with it personally. Otherwise, you pre-master an .iso file with "mkisofs," and then you record with "cdrecord." There are GUI tools build around those 2 programs to help you. That's for CD-R (or CD-RW emulating CD-R). > Here is my mtab: > $ cat /etc/mtab > /dev/mapper/VolGroup00-LogVol00 / ext3 rw 0 0 > none /proc proc rw 0 0 > none /sys sysfs rw 0 0 > none /dev/pts devpts rw,gid=5,mode=620 0 0 > usbfs /proc/bus/usb usbfs rw 0 0 > /dev/sda1 /boot ext3 rw 0 0 > none /dev/shm tmpfs rw 0 0 > none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0 > /dev/hdc /media/cdrecorder iso9660 ro,nosuid,nodev,user=froggy 0 0 > How do I change /dev/hdc /media/cdrecorder iso9660 ro to rw? You can't. You can't really "read/write" anything that is ISO9660. It is clear that this CD media (CD-RW?) was written as ISO9660. All you can do is append additional sessions/tracks (if CD-R), or re-format it (if CD-RW). These are just things that some Windows tools "hide" from you. But you still probably need to know about them. > $ cat /etc/fstab > # This file is edited by fstab-sync - see 'man fstab-sync' for details > /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 > LABEL=/boot /boot ext3 defaults 1 2 > none /dev/pts devpts gid=5,mode=620 0 0 > none /dev/shm tmpfs defaults 0 0 > none /proc proc defaults 0 0 > none /sys sysfs defaults 0 0 > /dev/VolGroup00/LogVol01 swap swap defaults 0 0 > /dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0 Stick in a new CD-RW media that has been formatted UDF and see what happens. -- Bryan J.

Re: New Server Recommendation -- Hot-Swap SATA enclosure ...

[ Yes, SP^M'n the list with follow-ups to myself ;-] From: Bryan J. Smith > If you are building a new system with such storage requirements, > I would really push you towards a 3Ware Escalade 8006-2 or 8506-4. When cost is supreme, then just a Escalade 7006-2 or 8006-2 with (2) [P]ATA or [S]ATA drives is what you want. It only adds ~$125 to system cost. When you want to minimize cost, but also minimize troubles, I recommend an Escalade 8506-4LP with an EN-8721A02 (Beige) or EN-8721B02 (Black) 5.25" x 3U (3xHH) internal enclosure. SATA was explicitly designed for hot-swap with fixed, SCA-like, staggered, fixed-position connectors with _no_ extra interconnect (i.e., like SCA SCSI drives, SATA drives _should_ connect _directly_ to the backplane, and the "can" is just a frame/handle), so _avoid_ doing such with [P]ATA which is only asking for issues. The EN-8721x02 will only set you back $150, so it's well worth it (especially when you're already spending $300 for the Escalade 8506-4LP, it's only 50% more). It's also nice to have an "extra can" for either holding a spare, or mounting a replacement without having to take one of the existing drives out before it is replaced.

I've been looking > for a recommended installation guide for RHEL4/CentOS4 giving > recommended disk partitioning I have personal recommendations I follow. One thing I really try to do is make 2-3 "classes" of filesystem sizes, with 1 "spare" for each. That way I can flop around filesystems, accomodate additions, etc... LVM/LVM2 helps reduce this, but I still like to use the approach (except I just don't make spares, I just reserve 15-30% of disk space for LVM/LVM2). E.g., the "essential" class is typically 2-8GB each. The "support" class is typically 8-64GB each. The "discretionary" class is typically 64+GB each. For all systems, I typically do these "essential" classes: / /tmp /var I also typically create the following "support" classes: /usr /usr/local (and a symlink from /opt -> /usr/local) And more "support" class filesystems for servers: /var (instead of an "essential" size) /srv (newer FHS 2.3+ compliant systems) /var/log /var/lib (application, database, etc... servers) /var/mail (mail servers) /var/spool (mail, print, etc... servers) /var/www (web servers) /var/ftp (FTP servers) In some cases -- FHS 2.3+ compliant -- these are under /srv instead of /var. If I want local data/temporary storage, I typically create of the "discretionary" size: /export|home/(systemname) I like to make at least _3_ "discretionary" size, 2 mounted with 1 spare, so 1/3rd each. Again, in the day of LVM/LVM2, I typically just reserve 15-30% of the disk allocation instead of making pre-made spares of each class -- but I would at least make _2_ "discretionary" size (instead of one big one). I also use "/export" when I know I'm going to be exporting them via NFS (and setting up my NIS/LDAP autmounter maps accordingly). Otherwise I use /home. Even if I'm not sure I'm going to export via NFS, if I'm sharing via SMB, then I put them under /export. In a nutshell, if they are network mountable (for whatever protocol), they are under /export. > as well as quotas. I've not used quotas with LVM yet. Don't quote me, but quotas are a filesystem issue and shouldn't matter with LVM/LVM2 disk labels. I'd personally like to see a performance evaluation of Ext3 v. XFS _with_ quota operations. Most comparisons these days seem to be "raw" block operations -- whether big or small -- instead of disk operations sysadmins would normally do day-to-day. > This box is going to have an 80 IDE system drive, an 80G SATA and a > 250G SATA for everything else.

If you are building a new system with such storage requirements, I would really push you towards a 3Ware Escalade 8006-2 or 8506-4. Have you already purchased the hard drives? If so, then merely buy a 2nd 80GB SATA and 2nd 250GB SATA with a 8506-4 and use RAID-1 for each. If not, then just buy a cheaper 8006-2 and use RAID-1 with (2) 300GB disks (you might consider this even if you already have some drives). > Does anyone know of a guide for this online?

New Server Recommendation

I'm about to deploy a new server for hosting sites and email for a number of small individuals using a CentOS 4 box. I've been looking for a recommended installation guide for RHEL4/CentOS4 giving recommended disk partitioning as well as quotas. I've not used quotas with LVM yet. This box is going to have an 80 IDE system drive, an 80G SATA and a 250G SATA for everything else. One thing I want to be sure of is that I don't run out of space for the mail spools in /var/spool/mail. Does anyone know of a guide for this online?

system environment variables

15 Jun '05

CentOS 3.x Don't know how this got by me, but for years I've been previously using /etc/profile to set system wide environment variables and now I just noticed it doesn't work any more (sort of). If you log in via console it works, log in via gdm, it does not, but use to work. Now I noticed if I create script files for the vars I want exported and include them in /etc/profile.d/ the vars get set either way. Is this now the correct way to set system environment variables by using script files in the /etc/profile.d/ ????? Sorry, I couldn't find info on this, most info says to use /etc/profile

To me, I really could care less about benchmarks except when real performance issues arise. All throughout 2.4, every other filesystem -- Ext3, JFS (from OS/2**), ReiserFS, etc... required hack after hack after hack. XFS, with its "core" additions to kernel 2.4 provided _everything_ standard from day 1 -- Quotas, POSIX EA/ACLs, etc... It was ported directly from Irix, and was _entirely_ GPL -- which you'd figure that's something Red Hat likes. The only bug that it ever ran into, which resulted in XFS 1.1, was something that bit me on 2 /var filesystems. Otherwise XFS, like Ext3 but _unlike_ JFS or ReiserFS, benefits from being the _exact_ _same_ organization for 10+ years. Which means not only is its on-line operation well-trusted, but it's off-line fsck/repair as well (something that plagues ReiserFS heavily due to design focus). Because I could care less how a filesystem works when it works. I want to know what happens when its inconsistent, and a journal reply won't solve the problem. I trust e2fsck and xfs_repair. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Since 2002, this is the #1 reason I've been advocating that Red Hat adopt XFS as its' 2nd, officially supported filesystem. xfsdump for XFS does this, and always has. You don't have to use "getfacl" to save POSIX ACLs (although that was always an option, even back in the early 2.4.x days for XFS). Everything (short of SGI-integrated hardware API support) came over from Irix in XFS for Linux, and that included POSIX ACLs, Quotas, etc... This is in stark contrast from IBM JFS which came from OS/2 instead of AIX (because of the legal issues with Monterey), and ReiserFS is a non-traditional UNIX design (I won't go there, even if it is very innovative in most respects). Most of these features in kernel 2.6 ere thanx to the SGI XFS team, and the team also worked with the Ext3 and Linux & co. as of 2.5.3+ in ensuring POSIX EAs were uniform across all filesystems c/o the VFS. I haven't wanted to bother Tweedie and/or Red Hat in getting an explaination why they aren't looking at supporting XFS, but I think it would solve a lot of scalability issues. I always assumed it wasn't merely a "NIH" attitude, and they had real reasons for not wanting to support it until Ext3 proved to be a serious limitation for them.

I have to be honest, I've never used xfsdump and verified SELinux attributes were preserved. But it should bring _all_ POSIX EAs with it. I've just typically relied on it for ACLs. -- Bryan J.

A questiong about replacing my failing drive
by Doug Eubanks 15 Jun '05

15 Jun '05

First, I am not a RedHat or linux newbie. I simply have not had to do what I am getting ready to do, and I want to see if I am going to run into a problems... My HDA drive is failing (I can hear the occasional click from it and I am seeing Smart errors, the transfer rate is slow but all my data is there). I have 3 partitions on it, the /, /boot/ and my game servers (this is also the drive the bootloader is on). Will this proceedure work ok to replace it with the minimum of downtime/reinstalling A> Make bootable floppy B> Start in single user mode C> Create same partition structure on hew drive D> Move all files from old partitions to new partitions E> Switch drives F> Boot off floppy, mount, reinstall grub and boot manager on new drive G> Profit! Any hangups or snags doing it this way? Thanks, Doug Eubanks doug(a)simflex.com

Still no go.... I have downloaded the SRC rpm for kernel-2.6.9-11.EL.src.rpm <http://mirror.centos.org/centos/4.1/os/SRPMS/kernel-2.6.9-11.EL.src.rpm> I did rpm -i kernel....src.rpm cd /usr/src/redhat/SPECS rpmbuild -bp --target i686 kernel.xxx.src.rpm cd /usr/src/redhat/BUILD/kernel.XXX/linux.XXX make bzImage make modules_install make install When I reboot I get the same error about "mount: error 19 mounting ext3" Where should I go from here? Thanks, Jerry

John, Thanks for the info. I am having trouble with the downloading of the src.rpm. Is that just on the mirrors somewhere or is there an easy place to grab the i686.src.rpm? I tried "rpm -Uvh kernel-2.6.9-11.EL.src.rpm" and got an error. Where on the mirrors is the i686.src.rpm?

I actually think it is kind of worthless and we will probably stop including it. Try this instead :) Download the kernel-xxxxx.src.rpm do: rpm -Uvh kernel-xxxxx.src.rpm go to the SPECS directory and do this: rpmbuild -bp --target i686 kernel-xxx.spec then go to the BUILD directory and go down to the kernel directory and build there. (substitute the versions for xxxxx ... also use the correct --target for the kernel you are trying to compile) This will get all the target related patches applied.

THe size of the ramdisk is not even close to the original. Which since I am using the same config I would have thought it to be the same size. initrd.2.6.9-11.ELcustom 307K initrd.2.6.9-11.EL 390K Jerry ------------------------ That is supposed to happen in the "make install". In fact I looked at /boot and it is there.
