Kernel-utils stupidities (readahead and cpuspeed)
by Simen Thoresen 12 Jul '06

12 Jul '06

Hi all, I think I've spotted a few stupidities (bugs) in the current version of kernel-utils (kernel-utils-2.4-13.1.80). I'm sure these are all propagated from upstream, but I hope someone could have a quick look to verify this and see if we either can push complaints upwards, or provide local fixes. The kernel-utils package provides several 'kernel-type' functions - readahead and readahead_early and also the cpuspeed have a few problems; readahead 'reads ahead' (stats to copy to cache for speedy access?) the files found in /etc/readahead.files. While most of these files are various images and common binaries, some are libraries which have been replaced by newer versions, thereby reducing the usefulness of readahead. Readahead.early uses a different file (/etc/readahead.early.files) to cache useful system libraries, including a few kernel modules - for the 2.6.3-2.1.238.2 kernel. Both readahead and readahead.early are installed as disabled. chkconfig lists them as 'off' in all runlevels. Worse, cpuspeed. This is from an Athlon64 system, so it is possible that this behavior is different on non powernow-k8 systems. On the CentOS4-x86_64 kernels, the cpuspeed-drivers are built into the kernel. Here, cpu speed-management works, as the /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver -file exists (tested for in /etc/init.d/cpuspeed). On CentOS4-i386, the powernow-k8-module is not built into the kernel, so the above test fails, and the cpuspeed startscript exits. There seems to be a plan for this. The /etc/cpuspeed.conf file can specify a DRIVER variable, but no attempt is made to insmod this, so even if this is set, cpuspeed still fails. A simple fix is to check for the presence of the above /sys entry, and if that is missing, modprobe $DRIVER. Without this, cpuspeed will never work on my systems. Does it work elsewhere? Yours -S -- Simen Thoresen, Dolphin ICS

3ware SATA RAID Card
by Jon 12 Jul '06

12 Jul '06

I've a 3ware Escalade 8006-2 and run Centos 4.2 using the latest kernel 2.6.9-34.0.2.ELsmp. I see that the card comes with some disk management tools called 3DM2 Management Utility. Is this ok to install? Is it good for reporting failed drives? Thanks Jon ___________________________________________________________ All New Yahoo! Mail Tired of Vi@gr@! come-ons?

Notebook suspend instructions -- Gentoo to Centos
by Robert Moskowitz 11 Jul '06

11 Jul '06

At: http://www.linux.com/article.pl?sid=06/05/24/1716222 are instructions for implementing suspend mode on a Linux notebook, but the script is for Gentoo and it seems like Centos needs something else. As this puts my system REALLY fast into Suspend, but it never comes back out. Further the temp file: var/tmp/video_state.XXXXXX is empty, so something is not right. Now for my system, HP NC4010, cat /sys/power/state results in: standby mem disk (I think that is the list, definitely 3 items with the 2nd being mem). I ASSuME that this meets what the instructions tell you need to see if your notebook supports acpi suspend. But grep ACPI_SLEEP KERNEL_CONFIG does not seem to have a SLEEP line. Well maybe I was not looking in the right place for the kernel_config. I was looking in /usr/src/ But echo -n mem > /sys/power/state really puts my system into a suspend mode fast. Perhaps part of the problem is with cat /proc/bus/pci/$ID > $TMP_FILE as there are a couple of directories in this directory. It is rather hard to supply more detailed information, as I have to keep rebooting between XP and Linux until I get Thunderbird migrated...

Hosting
by Mace Eliason 11 Jul '06

11 Jul '06

Hi I am using Centos 4.3 to host various web sites that I maintain. I am finding that I am getting more and more, and I have thought of setting up a hosting server to make things quicker for my self. I have setup webmin with virtualmin and it seems to work fine so far. What is everyone else using. I don't want to invest alot of money, but would like some thing that is quick and easy to setup a domain and mysql database, ftp etc. Right now I have to edit httpd, etc etc. Thanks Mace

SATA RAID Cards
by WipeOut 11 Jul '06

11 Jul '06

Hi, Which SATA RAID cards work natively on Centos 4.x?? I have heard that the only one supported is the 3ware cards but not sure if that requires a driver to be added or if it just works out the box.. Also would like to know of alternatives.. Thanks..

If you use the Bastille Scripts or the iptables to help secure access to webmin, you can defeat some of the exploits.

I never trusted webmin, seeing how many exploits (even root exploits) were available for it. usermin was the last I saw a warning for.

Hi, I recently installed centos for the first time and I like it! Also, I just started working with lvm. The following warnings are genertated whenever I run one of lvm commands on the external usb disk (MyBook by Western Digital). * What could be the source for those messages? * Should I worry about them (writing into the created LV's seems to work)? * If yes, how to fix them?
