C5 64-bit and software RAID 6?
by Scott R. Ehrlich 08 Mar '08

08 Mar '08

I have a Dell PowerEdge 2950 with 6 SAS disks and a PERC 5/i controller what won't do RAID 6. I plan to have 2 drives as RAID 1 for the OS, and the remaining 4 as RAID 6. Granted the PERC can do RAID 1, I'm tempted to do everything via software RAID. Thus, if anything goes wrong with the controller, I just need to obtain a new SAS controller and I'm back up. I learned my lesson about not using RAID 0 for important data storage when a drive goes bad! What are peoples' performance and reliability experiences with 64-bit C5's software RAID, particularly RAID 6? Thanks. Scott

Syntax question: svn propset on multiple file types?
by Niki Kovacs 08 Mar '08

08 Mar '08

Hi, I'm currently using SVN for writing some docs with LaTeX, and I wonder how I could possible tell SVN to ignore all *.log, *.aux and *.dvi files. I know how it can be done for one at a time. Let's say my files are in the docs/ directory. Then I'd go into the parent directory and do: $ svn propset svn:ignore *.log docs/ But what should the command be if I wanted to ignore *.log, *.aux and *.dvi? thanks, Niki

Getting JRE working in Firefox
by Robert Moskowitz 08 Mar '08

08 Mar '08

I have installed both: jdk-6u5-linux-i586-rpm.bin jre-6u5-linux-i586-rpm.bin But no Java plugin in Firefox. I go to: http://java.com/en/download/help/enable_browser.xml And yes, Java is enabled but still get the dreaded 'download plugin'. I seem to recall some magic linking needed, but my docs are in Freemind that I can't get installed either.....

firefox always goes to tw/youtube.com
by P Marvin Eberly 08 Mar '08

08 Mar '08

Hello list, I'm sure this is something simple I'm missing. On CentOS 4.6 fully updated, stock Firefox, if I type in http://www.youtube.com in the address bar it always goes to http://tw.youtube.com and has the encoding all messed up. Same happens if I click on any link to youtube. SeaMonkey does not display the same symptoms and works correctly. firefox-1.5.0.12-0.10.el4.centos.i386 Can someone help me get this fixed? TIA, -- P Marvin Eberly <eberlyml(a)wjtl.net>

Re: [CentOS] Unable open raw socket in CentOS 5 - SE Linux and kernelcapability interaction?
by Ross S. W. Walker 07 Mar '08

07 Mar '08

The raw socket option in the kernel only allows privileged processes to open them. Selinux controls which privileged processes have the right to. To allow an unprivileged process to access a raw socket you will need to write a proxy daemon that runs privileged and is allowed in selinux to create a raw socket. This daemon can then provide a unix socket to unprivileged processes whose access can be granted with it's security modes and ownership either manually or through udev. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 07 17:44:15 2008 Subject: Re: [CentOS] Unable open raw socket in CentOS 5 - SE Linux and kernelcapability interaction?

Hi, I was wondering what would be the best way to learn AIX, Solaris, or HP-UX, for someone who knows Linux very well? Books? Courses? Self-teaching in a home lab? Thanks, Ugo

Re: [CentOS] Problem getting JavaRuntime EnvironmentinstalledintoOpenOffice
by Ross S. W. Walker 07 Mar '08

07 Mar '08

You may need to look at 'alternatives' and see if Sun java is still set and set it again if it isn't. If it still doesn't work after that try uninstalling OOo and reinstalling it. If it doesn't work after that, well you may want to try the 32-bit versions to see if they work together. Another good question, are you running the 32-bit or 64-bit version of OOo? I believe the 32-bit OOo will only work with the 32-bit Java, not sure if that is true the other way around though. Is there a reason the GNU Java won't work for your needs? -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 07 17:40:07 2008 Subject: RE: [CentOS] Problem getting JavaRuntime EnvironmentinstalledintoOpenOffice >> Sure I'll give that a try.
