kickstart install using url location
by Carlos Santana 21 Jul '09

21 Jul '09

Hi, I am working on a kickstart install method and it works fine with cdrom as installation media. I would like change this media to an online resource. I saw option as - 'url --url http://<server>/<dir>'. I am not sure what should be the directory contents? Should we put all ISOs in that directory or what? Any insights? Thanks, CS.

Centos 5 samba with AD integration and XFS with extended ACLs
by Coert Waagmeester 21 Jul '09

21 Jul '09

Hello all, Firstly, I have checked on google, and there are indeed howtos on this subject. Have any of you done this or something similar on CentOS? If so, could you send me the configs maybe? How can I find out if the centos version of samba supports extended ACLs? I ran a modinfo xfs, and XFS supports it. I want to set up a samba server that authenticated to AD. I have that up and running, only the extended ACLs still to do. Thanks in advance, Coert

TwinView (on NVIDIA graphics card)?
by Toralf Lund 21 Jul '09

21 Jul '09

Hi, Is anyone here using TwinView with NVIDIA graphics drivers under CentOS 5? Just tried this configuration (I've been using dual monitors as separate X screens in the past), and while it works in a sense, there are a few issue that will probably prevent me from using it for real. Notably, which screen new applications start on (when using the Applications menu or panel launchers) seems to be quite arbitrary. I expect windows to open on whichever screen I initiated their creation, I suppose, but they will often appear on the other one. This is using the GNOME desktop. Another slight issue is with the notification icons. I really want to display duplicates of these, so I can view them on both screens, but is seems like the Notification Area doesn't work this way, i.e. it will never display more than one of each icon even when there are several instances of the area. But this is a problem I also have when using separate X screens. So, what are other people's experiences with a dual monitor setup? - Toralf This e-mail, any attachments and response string may contain proprietary information, which are confidential and may be legally privileged.

SSH without password on CentOS 5 ?
by Niki Kovacs 21 Jul '09

21 Jul '09

Hi, I'd like to use SSH without password so I can use it in scripts (for example in combination with rsync to do backups). I have Carla Schroder's "Linux Cookbook" and I'm trying out the various receipts, but the one for SSH without a password doesn't work. The book is slightly dated, and I wonder if SSH included in CentOS works differently. Any suggestions? Niki

CentOS on IBM Bladecenter HS21
by Andrei F 20 Jul '09

20 Jul '09

Hello, I have CentOS 5.2 installed on two of the afore-mentioned blades. I've noticed that the OS started to crash lately (kernel panic) and I've been assigned the task to troubleshoot this issue. I would like to know what is the best way of recovering the kernel dump after the OS crashes. I know there are two software implementations that would enable me to do this, kexec and 'crash' , redhat's own implementation that allows you to pust the dump via network to a remote machine. What would be the best thing to do at this point? Regards, -Andrei F

Glibcxx_3.4.9 not found
by Chris Heaton 20 Jul '09

20 Jul '09

Hi, I am running CentOS 5.3. 64 bit version. I have tried updating the OS but every time I run an application I need it reports that Glibcxx_3.4.9 is missing. I tried to do a search for this but cannot find it for my system. When CentOS upgraded to 5.3 I had hoped that the new Glibcxx would have been included but it is not. Is there an easy way to update the OS to include this? You can probably tell from the question that I am a Linux Newbie so please try to keep the answers simple. Many Thanks Chris

NUT problem
by Anne Wilson 20 Jul '09

20 Jul '09

A little while ago I changed my UPS to Leibert and installed NUT. Everything worked as expected. Today I tried to use the MultiLink Viewer icon from the desktop, but it simply accepted the root password without apparently doing anything. I can run the viewer directly (as root) from a file manager. The icon is owned by me, but the application is set to run as root. I suspect that the problem is with 'kdesu'. The command 'kdesu /opt/MultiLink/bin/Viewer' which is what the icon runs, brings 'kdesu /opt/MultiLink/bin/Viewer' bash: kdesu /opt/MultiLink/bin/Viewer: No such file or directory From a root terminal, however, /opt/MultiLink/bin/Viewer /opt/MultiLink/jre/bin/java -cp .:/opt/MultiLink/lib/em.jar - Djava.compiler=NONE com.liebert.dpg.app.LxExecutor mainViewer /opt/MultiLink cfg/executor.cfg What changes do I need to make to be able to use the desktop icon again?

Anaconda crashing on new machine
by fred smith 20 Jul '09

20 Jul '09

Hi! I'm building up a new computer and this evening have had several events during installation in which Anaconda has crashed. It's not clear that there is a lot of commonality between the different crashes. the first time I got all the way through package selection (selecting at the individual package level) before it crashed. the second time I made a mistake in partitioning and did BACK several screens to fix it, then when clicking NEXT several times to go forward to where I had been, it blew up. then it blew up while partitioning. then it blew up there again, though at a different place. I don't think there should be any problem with making /home 200 gigs,... doesn't ext3 have a limit something more like a terabyte or more? it's a gigabyte GA-MA770-UD3 board with an AMD Phenom II X2 550 clocked at 3.1 Ghz, and 4 gigs of g.skill ram (which has run for several hours under memtest86+ with no problems.) Anyone got any helpful suggestions! BTW, I ran 3 different live-Cd distros on it today, for several hours, just looking for problems, and didn't find any, so I'm thinking the hardware is reasonably stable. (one always wonders, when it's all brand-new.)
