slow Perl on CentOS 5
by Florin Andrei 18 Sep '08

18 Sep '08

If your Perl apps are unusually slow on CentOS 5, have a look at this blog: http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/ In a nutshell: some Perl apps are 100x slower on RedHat / CentOS 5 compared to other distributions.

Problems with writing Dual Layer DVD
by Chris Geldenhuis 15 Sep '08

15 Sep '08

Hi, I am running Centos 4 (fully updated on this box). I removed the old DVD writer (/dev/hdc) and installed a new LG GH20 "Internal Super Multi DVD Rewriter" with a SATA interface - this shows up as /dev/scd0. When I insert a pre-recorded DVD autorun mounts it and displays the contents without any hassles. It appears to me that the required kernel modules are loaded - as copied below from lsmod output. sata_nv 18629 0 libata 111261 1 sata_nv sd_mod 17217 0 scsi_mod 125261 3 sr_mod,libata,sd_mod I am using Verbatim DVD-RDL blanks. When I try to write a pre-recorded iso to the DVD I get the following error message: [user@test]$ growisofs -dvd-compat -Z /dev/dvdwriter=<pre-recorded>.iso :-( /dev/dvdwriter: media is not recognized as recordable DVD: 10015 I have tried to do this as root with the same result. /dev/dvdwriter is a link to /dev/scd0 and has full read/write/execute permissions. Output of growisofs -version: * growisofs by <appro(a)fy.chalmers.se>, version 5.21, front-ending to mkisofs: mkisofs 2.01 (i686-pc-linux-gnu) Any suggestions will be welcome - if any further information is required I will do my best to supply it. I have Googled with the error message but only get reports of this problem and no solutions. TIA ChrisG

Configuring an Intel 3945 wireless card: partial success
by Niki Kovacs 05 Sep '08

05 Sep '08

Hi, My wife has a new ASUS laptop with an Intel 3945 wireless card. I'm running CentOS 5 on all our desktops here (at work and at home), and I'm quite happy with it. I had a partial success in configuring the wireless card. Basically I'm using [base], [updates], [extra] and [rpmforge] repos, configured with the yum-priorities plugin. Priority 10 for RPMForge, 1 for the others. From RPMForge, I installed dkms-ipw3945, the driver for my wireless card. I gave it a first go with the most basic setup, that is: static IP, no encryption. After installing the driver, the card shows up as eth1. I removed /etc/sysconfig/network-scripts/ifcfg-eth0 and edited a minimalistic ifcfg-eth1. After a restart, the interface comes up OK, and I can connect to my access point as well as ping machines on the internet. But now I'd like to install and use NetworkManager. I've read the according Wiki entry on the CentOS site. Here's what I did: 1) Added the 'NetworkManager' and 'NetworkManagerDispatcher' services (using chkconfig) 2) Removed the 'network' service (also using chkconfig) 3) Rebooted to be sure Result: 1) The NetworkManager icon shows up OK on the upper right side of my GNOME desktop. 2) When an Ethernet cable is connected to the machine, NetworkManager configures a connection OK (cable connected to router). 3) The wireless ESSID of my access point shows up OK in NetworkManager. Ethernet cables get some sort of priority in NetworkManager, so I unplugged the cable and clicked on the wireless connection. NetworkManager tries to establish a connection for about 30 seconds, but fails. ... which leaves me clueless. Any suggestions? Last detail: for the moment at least, I'm using no encryption at all on the access point. We live in a very remote place in the south French countryside, there's only hunters and wild boars around, so it's not a very friendly place for wlan-hackers :o) Niki Kovacs

Changing swap resume signature location
by Patrice Guay 03 Sep '08

03 Sep '08

At boot time, the system is looking for a resume signature on the default SWAP partition that was defined during the OS installation. On several systems, I changed the location of the SWAP partition. How do I change the location where the system looks at boot time for the resume signature? Thanks, -- Patrice Guay patrice.guay(a)nanotechnologies.qc.ca
