Setting CDROM parms
by Robert 03 Jan '10

03 Jan '10

My apologies in advance for asking such an elementary question. I called myself searching the Installation Guide and Deployment Guide, with no success. The situation is that I bought a Lite-On ATAPI iHAP122 that will not burn DVDs unless I use hdparm to turn dma off. I bought that drive because it was a rare beige drive. Until I can find a decent DVD burner and/or get a Windows machine put together strictly for doing BIOS updates, running with dma disabled seems to be the best solution. (hdparm -d0 /dev/hdb ) So, my question is, where should I script the command without having to become root each time I wat to burn a DVD? 2.6.18-164.9.1.el5PAE #1 SMP Tue Dec 15 21:41:47 EST 2009 i686 athlon i386 GNU/Linux This is how it always fails: [rj@madeleine ~]$ growisofs -dvd-compat -Z /dev/hdb=/home/rj/KNOPPIX_V6.2DVD-2009-11-18-EN.iso Executing 'builtin_dd if=/home/rj/KNOPPIX_V6.2DVD-2009-11-18-EN.iso of=/dev/hdb obs=32k seek= 0' /dev/hdb: "Current Write Speed" is 16.4x1352KBps. :-[ WRITE@LBA=30h failed with SK=4h/ASC=08h/ACQ=03h]: Input/output error :-( write failed: Input/output error /dev/hdb: flushing cache /dev/hdb: updating RMA /dev/hdb: closing disc [rj@madeleine ~]$

reading -- and editing -- ebooks
by ken 03 Jan '10

03 Jan '10

Last week I bought a couple books, not ebooks. I considered buying the ebook, but don't want to need a special device/appliance to read it. I'd much prefer to read ebooks on the Linux (CentOS) machine I'm already using. Also, I'd like to be able to programmatically convert the ebook into a format I can edit myself, e.g., HTML. I have no experience owning or purchasing ebooks. Could people who have clue me in on how they work and if the above is possible. Thanks much. -- Without music, life would be a mistake. --Friedrich Nietzsche

kickstart and logins.def question
by Kwan Lowe 03 Jan '10

03 Jan '10

Hello all: Happy New Year to everyone and thank you for all the knowledge this past year. I have a hopefully simple question about kickstart. In the authconfig section I can enable ldap, credential caching, etc.. Using the GUI tool there's an option to create the user home directories on first login. The docs don't show a similar option for authconfig in kickstart. For now I'm using a sed script in the %post section of the kickstart to replace the entry in /etc/login.defs, but was curious if there is a standard method via a system utility to change this option.

Sparc?
by Slack-Moehrle 02 Jan '10

02 Jan '10

My 12 year old wants to learn more about servers and has memorized a lot of commands like ls, chmod, du, etc. He wants to have his own domain and server on the web and I have enough Static IP's, so why not foster this interest. I have an old ultra sparc 5. Are there any CentOS versions that support Sparc? Or recommendations? I know OpenBSD does, but I am more versed in Solaris and versions like Slackware or CentOS or Ubuntu. He also says that ZFS rules all and is pissed Apple did not adopt it. Kids will be kids! -Jason

chroot problem.
by Frank M. Ramaekers 02 Jan '10

02 Jan '10

First, I'm trying to following along on a document on "SecurityFocus" on "Securing MySQL: step-by-step". I'm on step 3.8 "Test the configuration". I have my CHROOT directory structure setup and the chrootuid is failing (haven't figured that one out, yet). So, I simply tried a 'chroot /chroot/mysql' and got: chroot: cannot run command `/bin/bash': No such file or directory I realized that the documentation didn't cover this so I simply: cp -a /bin/bash /chroot/mysql/bin I'm still getting the same error message when I try 'chroot /chroot/mysql': # chroot /chroot/mysql chroot: cannot run command `/bin/bash': No such file or directory It's there, I'm not sure what the problem is: # ls -l /bin/bash -rwxr-xr-x 1 root root 859120 Oct 24 2008 /bin/bash # ls -l /chroot/mysql/bin/bash -rwxr-xr-x 1 root root 859120 Oct 24 2008 /chroot/mysql/bin/bash (I'm performing this as root, since the mysql userid cannot login.)

need to free space on a root partition.
by Yan Yu 02 Jan '10

02 Jan '10

Hello, there, Happy new year everyone! I am puzzled here. Could some expert help me shed some light on this? this may not be a centos specific Q.. i have a linux machine. and the root partition (/) is full.. so I moved a dir from /data to /var (/var is on a different partition), and created a link from /data/fa to /var/xyz, the files under /var/xyz is about 8G, du /var/fa 8701248 /var/fa so I thought this should free some space for me, but when I used df, it gave me similar results before and after the move.. and my rpm installation would fail due to the lack of space.. Filesystem 1K-blocks Used Available Use% Mounted on /dev/cciss/c0d0p6 15235040 15232452 0 100% / /dev/cciss/c0d0p8 other partitions have free space.... I was confused on why moving a 8G file to another partition did not free some space for me? and I did see that the disk usage for the destination partition/disk increases after the move.. any pointer is appreciated! yan
