non-graphics install or fix xorg.conf?
by Robert Moskowitz 24 Sep '08

24 Sep '08

Trying the to install on the OQO, and hitting up against one problem I see a lot in the comments about installing various distros on it. That is its screen size. So I could install using the text installation except... What is the command line for text install and askmethod so I can use HTTP to access my local repo? What do I add to 'linux askmethod'? And if I go the text install route, can I do all of my custom disk partitioning? I seem to recall from when I fell intotext install on a system without enough memory, that I could not work with LVM in text mode. Or Can I set the video size in that 'linux askmethod' line? Here is a sample xorg.conf I have found: Section "Device" Identifier "Silicon Motion, Inc. SM720 Lynx3DM" Driver "vesa" # Driver "siliconmotion" # need to modify the driver first before using BusID "PCI:0:6:0" EndSection Section "Monitor" Identifier "Generic Monitor" Option "DPMS" Modeline "800x480" 40 800 864 928 1088 480 481 484 509 +HSync EndSection IF I have to go with a custom kickstart file from diskette (Drive a:), I suppose I could put the hardware together for it. I would need a powered USB hub (around here somewhere), my USB diskette drive, along with the USB CDrom.... How best to proceed? Oh, for my custom disk partitioning, besides the ext3 partition for /boot, I create a separate swap partition of memory x 2 (=2Gb). Then the LVM partition has two ext3 partitions, one for / around 12Gb, and the other for /home as the rest. The drive is a 60Gb drive, so I might make / bigger: ext3 /boot 100mb swap 2Gb LVM Rest of drive (to 512byte multiple) ext3 / 12Gb ext3 /home rest of LVM

kernel and memory question
by Mag Gam 24 Sep '08

24 Sep '08

Currently at my university we are running many servers with Centos 4.6 and everything is okay, but when a user does a large operation such as 'cp' or 'tar' or 'rsync' all of the physical memory gets exhausted. Our lab servers have 32GB physical to 64GB of physical memory and when a user does a large copy which involves very small but over 10k files eventually we see a kswap process. I would like to control swapping so these files don't go into memory instead they get flushed out. These computers are used for fluid dynamics calculations and I would just like to have the memory do a FIFO and use the least swap as possible. I tried setting the swapiness to '10' or '0' but that really does not help. Also, has there been a major memory management advancement from 4.6 to 5.2? If so, where can I read about the changes? TIA

Hi everybody, we using our centos server with vsftpd and windbind. our users can log on via ftp on the centos server by using their windows-ad-domain-accounts. That's working fine. But vsftpd doesn't auto create user home dirs, if the user connects the first time to the system. Anybody some suggestions why?

More on Linux on the OQO
by Robert Moskowitz 24 Sep '08

24 Sep '08

I am going over: ftp://ftp.oqo.com/unsupported/linux/OQOLinux.html This is for the 'older' model 1, I have the model 2. The files are 18 mo old, and relate to kernel 2.6.10. Of course I want to avoid a custom kernel, but please help me understand what is being covered here: "2. Enable crusoe processor in kernel .config CONFIG_MCRUSOE=y" What is the crusoe processor? 3. Programs such as 'hwclock' synchronize on the RTC periodic interrupt for accuracy. We need to disable RTC IRQ support in the kernel as we don't get the periodic interrupt. In the kernel .config set CONFIG_HPET_RTC_IRQ to 'y'. This enables the high performance event timer irq and in the process disables the rtc driver interrupt code: CONFIG_HPET_RTC_IRQ=y" How do I do this with the Centos kernel? "4. ACPI processor module (idle handler) interferes with transmeta longrun scaling. Set ACPI_PROCESSOR to 'n' or not set # CONFIG_ACPI_PROCESSOR is not set" Does this mean I have acpi=none in the kernel line? I really hope not. "5. Kernel preempting option currently causes a bug to show up in the wifi drivers, turn it off CONFIG_PREEMPT=n" I would hope to be using the dkms madwifi stuff. Do I need this? "6. Download the latest rtl8150 drivers from CVS at: https://sourceforge.net/cvs/?group_id=15970. The drivers in the base 2.6.10 tree will kernel panic upon removal of the dock. Copy the new driver to linux/drivers/usb/net/rtl8150.c" Don't see this as a problem as Centos has rtl8150 support. "7. In drivers/input/serio/i8042-io.h, add 'i8042_noloop = 1' in the function i8042_platform_init(). You only really need to do this if you have OQO subprocessor version 10/5 (It'll say 'EC Build 10/5' on BIOS post)." What is this all about? Still haven't actually tried an install.....

install of Pod::Simple through CPAN
by Al Sparks 23 Sep '08

23 Sep '08

I'm running CentOS 4.4. I'm trying to install swatch (a log watcher) using CPAN. It's getting hung up on trying to install a dependency, Pod::Simple So before I get too wrapped up in this, I have the following questions: 1. Is there an alternative way to install swatch? I didn't get a hit when I tried yum. 2. I'm not wedded to swatch. Is there another log checker out there that will work with CentOS? 3. Lastly, here's the error I get when I attempt to install Pod::Simple through CPAN: Test Summary Report ------------------- t/xhtml01 (Wstat: 512 Tests: 26 Failed: 2) Failed tests: 24, 26 Non-zero exit status: 2 Files=53, Tests=1095, 9 wallclock secs ( 1.30 usr 0.10 sys + 7.22 cusr 0.78 csys = 9.40 CPU) Result: FAIL Failed 1/53 test programs. 2/1095 subtests failed. make: *** [test_dynamic] Error 255 ARANDAL/Pod-Simple-3.07.tar.gz /usr/bin/make test -- NOT OK //hint// to see the cpan-testers results for installing this module, try: reports ARANDAL/Pod-Simple-3.07.tar.gz Running make install make test had returned bad status, won't install without force Failed during this command: ARANDAL/Pod-Simple-3.07.tar.gz : make_test NO

ASUS P5GC-MX/1333+ WD SATA
by Eduardo Grosclaude 23 Sep '08

23 Sep '08

Hi, I'm puzzled by an ASUS P5GC-MX/1333 with a WD320AAJS disk. My 5.2 DVD refused to see the hard disk. As the CD happened to have a bad MD5 sum, I assumed this was due to a bad burnt image. Backed off to 5.1. Installation of 5.1 to /dev/sda went OK, then I upgraded by yum to 5.2. But, at the next boot, the new kernel can't see the disk. Only when BIOS IDE Setup is "compatible" I can boot the new kernel. However, the disk shows up as /dev/hdc and performance is noticeably slow. If I choose any other mode, nash complains that any LVM groups can't be found and panics away. I/O in general is terrible. Copying a CDROM to a file with dd renders the machine nearly unusable. The kernel provided in 5.1 can work in the BIOS IDE Setup "enhanced/SATA" and performance is really good. Hdparm when under the current kernel says 3.51 MB/s buffered speed, whereas for the older kernel it claims some 111+ MB/s. I have updated the BIOS ROM to no avail. What am I missing? Is there anything I can do except keep trying kernel updates? TIA -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

Centos Kernel 4.7 Compile Help
by Steve Moccio 23 Sep '08

23 Sep '08

Hello Everyone, I wanted to recompile the kernel from source. I downloaded the source rpm (kernel-2.6.9-78.0.1.EL.src.rpm) from centos and installed the rpm. In /usr/src/redhat I unzipped and untard the linuxx-2.6.9 base files. After doing that I wanted to patch the kernel with the numerous patch files that came with the src rpm. The problem that I am having is that a lot of the patch files fail an example: patch -p1 < ../linux-2.6.9-megaraid-update.patch patching file drivers/scsi/megaraid/mega_common.h Hunk #1 FAILED at 27. 1 out of 1 hunk FAILED -- saving rejects to file drivers/scsi/megaraid/mega_common.h.rej patching file drivers/scsi/megaraid/megaraid_mbox.c Hunk #1 FAILED at 10. Hunk #2 FAILED at 217. Hunk #3 FAILED at 244. Hunk #4 FAILED at 286. Hunk #5 FAILED at 340. Is this not the right procedure for patching the kernel? Any insight would be appreciated. Thanks, Steve
