Asus Xonar DX PCIe sound card?
by tony＠softins.clara.co.uk 09 Feb '10

09 Feb '10

Can anyone here report success or failure at making the Asus Xonar DX PCI-express sound card work under CentOS 4? Or failing that, 5? Google only turned up people using it on Ubunt or SuSE... I need to specify the addition of audio outputs to a HP DL360 system, and don't want to buy stuff that will be a pain to get working. :-) Or can anyone recommend any other simple sound cards for PCI-express that have been trouble-free under CentOS 4 or 5?

auto mounting group shares
by Carlos Santana 09 Feb '10

09 Feb '10

I am using autofs to mount user's home and group directories. The setup works fine for home directories which are mounted after user logs in. The group shares are also mounted, but user has to manually do cd or ls command on group shares, e.g.: ls /groups/chemistry will mount chemistry group share. Is there any way to mount group shares automatically? I noticed that after successful login 'some program' performs chdir (cd) which probably tells autofs to mount home dirs. Which program does this operation? Is there any way to do this for group shares also? - CS.

slowness in sendmail - 60 second timeout

iSCSI + kickstart
by Ugo Bellavance 08 Feb '10

08 Feb '10

Hi, (I'm using RHEL, but I posted on redhat.general and rhel5 mailing lists and didn't get an answer, so I'm taking a chance here as well) Two of my servers have 2 nics (HP DL495c G5). Using RHEL 5.4, I'd like to do a network install to boot from iSCSI, as the NIC supports it, following this document: http://kbase.redhat.com/faq/docs/DOC-6875. However, since my data network is on a network segment that is separated from the SAN (iSCSI) network segment, I'd need to install from pxeboot using the LAN VLAN, but configure another nic so that it has access ot the SAN VLAN. From what I can see, it is not possible to assign a vlan in kickstart, and kickstart can only configure one NIC using the --network parameter. However, I managed to configure another nic using a %pre%. It also looks impossible to create a bonded interface in kickstart, which I'd like to be able to create. Ideally, I'd like a bonded interface in failover mode, and some vlan'd interface on top of the bonded interface. But I could manage that afterwards, I guess. It looks like only my first physical NIC can boot from the SAN, so ideally, I'd need to have a eth0 to be in the SAN segment, and configure eth1 for the LAN, so that it can see my dhcp, pxeboot and tftp server. Then I guess I must change the boot mode of my NIC so that it boots using iSCSI instead of PXE (after the install). But then, will multipath be configured? Since I have two controllers, the lun shows me two disks... If anyone has had experience with this kind of installation, please let me know. Thanks, Ugo

Changing size of a xen guest filesystem
by Jussi Hirvi 07 Feb '10

It should be easy, but I have not yet found a solution. Only some methods involving use of dd, but that sounds a little scary to me on a production server. I wish there would be a command "virt-resize", but no... Maybe "virt-clone", with the option --file=DISKFILE, could be bended to do this? - Jussi Hirvi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi(a)greenspot.fi * http://www.greenspot.fi The point is that what each one of us does from the time we wake until the time we sleep makes a difference. - Jane Goodall

Somewhat off topic: Building Android on CentOS 5.4
by Paul R. Ganci 07 Feb '10

07 Feb '10

I asked this question on android-platform(a)googlegroups.com but never received a response. I suspect most (if not all) people compiling the Android platform are using some version of Ubuntu ... hence the lack of response. I would not normally cross post but am hopeful that another CentOS 5.4 user (not on the android-platform forum) might have successfully built the Android platform. I would be extremely grateful if he or she could publish the procedure they used to do so. In any event here is the motivation of why I want to build the Android platform and a description of the problem I encountered: I have a Samsung Moment which the Android module adb will not detect due to a bug in usb_linux.c. Therefore I have been trying to compile a patched version of adb on Centos 5.4. I have followed these instructions in effort to build adb on cupcake: > > cd $HOME/download/android > > repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake > > repo sync > > cd system/core/adb > > patch -b usb_linux.c usb_linux.c.patch > > cd ../../.. > > make adb > build/core/product_config.mk:261: WARNING: adding test OTA key ============================================ TARGET_PRODUCT=generic TARGET_BUILD_VARIANT=eng TARGET_SIMULATOR= TARGET_BUILD_TYPE=release TARGET_ARCH=arm HOST_ARCH=x86 HOST_OS=linux HOST_BUILD_TYPE=release BUILD_ID= ============================================ /bin/bash: line 0: cd: dalvik/libcore//mnt/home/ganci/download/android//dalvik/libcore:/ No such file or directory /bin/bash: line 0: cd: dalvik/libcore//mnt/home/ganci/download/android//dalvik/libcore:/ No such file or directory dalvik/libcore/Android.mk:150: dalvik/libcore//mnt/home/ganci/download/android/dalvik/libcore/sub.mk: No such file or directory make: execvp: /bin/bash: Argument list too long make: *** No rule to make target `dalvik/libcore//mnt/home/ganci/ download/android/dalvik/libcore/sub.mk'. Stop. Everything works until the make. I have tried several different variations including making everything but everytime it seems the make is very confused about the directory structure. It is as if make is concatenating the relative directory dalvik/libcore with the full path /mnt/home/ganci/download/android/dalvik/libcore. I am open to suggestions.

OK, this is the perfect sequay for me :-) Assuming you only want Linux, and at that CentOS Linux - which are both the case for me - what Config Management system would you use? What is out there? A few months ago I sort of had a similar thread going and got the following : Slackmaster - looks like this is from google chef - have not looked it up yet puppet - got a test bed going and just bought the book because have not found much on line in terms of complex configs and how to actually use it to manage your environments bcfg2 - have not looked for it yet CF Engine - am vaguely familiar with it. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Virtualization - what do You recommend?
by Rafał Radecki 06 Feb '10

06 Feb '10

Hi All. I plan to use virtualization in my production environment. I plan to use one of the following options: - KVM; - VMWare Esxi; - VMWare Workstation. I plan to install Windows 2008 as a guest. I want to use something like LVM snapshots for backups. Stability is also very important, the guest will be used as a production server. Which option could You recommend and why? Thank You very much in advance :) With regards, R.

Dear All I want to use XEN to install Windows XP as guest on CentOS 5 as host . I tried as the followings : #yum install xen virt-manager kernel-xen #chkconfig xend on #reboot Then I booted my CentOS server using XEN kernel . I tried as the followings : #virt-manager & But when continuing to create the virtual machine , under Installation Method menu , I cannot select 'local install media (cdrom)' and just the Network install tree is highlighted . So I tried to reach the desired one , by issuing as the followings : #virt-install --paravirt --name WindowsXP --ram 128 --file /vm --location /mnt/cdrom But it didn't get through as well . Can you please let me know how can I do it correctly ? Thank you Hotmail: Trusted email with powerful SPAM protection.

I have a fairly high disk i/o intensive email server I am thinking of upgrading. I was thinking of upgrading it to CentOS 5.x 64bit. I was also thinking of running it as a guest under XEN. Would this allow me to more easilly transfer it to faster hardware in the future? Or would running as a guest seriously hurt disk i/o?

VMWare ESXi & CentOS5.4
by Thom Paine 05 Feb '10

05 Feb '10

I have a brand new Dell Poweredge T310 server with 4G ram and 1TB raid-5 hard drive in it. I Really only need to be able to run a copy of CentOS 5.4 on it, but I'm wondering if in the build process should I stick on ESXi 4 and then run CentOS as a vm? This would give me the options to roll out other VM's if I want over the life of the server (which I likely won't need) but the convenience of having them might be there. I'm only thinking of doing this because ESXi is free, and won't add any cost to this server. This server is going to be a domain controller for 5 workstations which will run Windows XP, as well as host 1 website with email. It will setup a few shares for samba, and have one network printer attached to it. Any thoughts to this, or should I just put on CentOS 5.4 and be done with it? I know it's like asking what everyone's favourite colour is, but maybe a few replies will give me some ideas. Thanks. -- -=/>Thom

OpenSSH-5.3p1 selinux problem on CentOS-5.4.
by James B. Byrne 04 Feb '10

04 Feb '10

Note: I am digest subscriber so if you could copy me directly on any reply to the list I would appreciate it very much. I sent this to the OpenSSH list (secureshell(a)securityfocus.com) yesterday and received no response so I am asking here in hopes that someone else has run across this problem on CentOS. We have encountered a situation that requires sftp access to one of our server by an outside agency. This will be used for a data push application only and we need to secure our server from trespass via this access. After a modest amount of research we decided that the best answer was to use a more recent version of OpenSSH (5.3p1)that supports chroot as a configurable option. I obtained the software from the openssh.org website and built it using the libedit packages from the CentOS testing repo. These were the option used: ./configure --prefix=/opt --with-libedit --with-md5-passwords --with-pam --with-selinux --with-tcp-wrappers The new server software works fine for regular ssh/sftp users. However, when logging on as a member of the chroot group we obtain this error: ssh_selinux_getctxbyname: ssh_selinux_getctxbyname: security_getenforce() failed I have found reports of this exact error via Google in several places dating back to 2006, but these all seem to devolve into either: this has been fixed in version x.y.z on distribution Q, where x.y.z is less than 5.3 and Q is not CentOS. Or, the selinux filesystem has to be mounted inside the chroot directory. Since I assume the former is never going to happen for CentOS, at least not in time to do me any good, I am looking for an explanation of what the latter means and how it is accomplished. Our current SELinux status on that host is: # sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: permissive Mode from config file: permissive Policy version: 21 Policy from config file: targeted Our chroot directory path is: /var/data/sshchroot The questions are: 1. Is it possible to mount the selinux filesystem twice on the same host having different roots? 2. If so, then how is this accomplished? 3. If not, then is there anything else that I can do, besides disabling selinux support in the sshd daemon, to get this to work? Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

Yum: strange dependencies
by Fajar Priyanto 04 Feb '10

04 Feb '10

Hi all, On Centos 5.4 minimum installation, I tried to install these packages (notice the dependencies): =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Installing: mc i386 1:4.6.1a-35.el5 base 2.1 M mdadm i386 2.6.9-2.el5 base 827 k ntp i386 4.2.2p1-9.el5.centos.2.1 updates 1.3 M sudo i386 1.6.9p17-5.el5 base 218 k Installing for dependencies: exim i386 4.63-3.el5 base 1.2 M mysql i386 5.0.77-4.el5_4.1 updates 4.8 M perl i386 4:5.8.8-27.el5 base 12 M perl-DBI i386 1.52-2.el5 base 600 k postgresql-libs i386 8.1.18-2.el5_4.1 updates 196 k Transaction Summary =================================================================================================================== Install 9 Package(s) Update 0 Package(s) Remove 0 Package(s) Total download size: 23 M I didn't want all those dependencies, especially exim and mysql. So, instead of installing mc, mdadm, ntp, and sudo at the same time, I installed them one by one and this time no exim and mysql (mc still wanted perl, fine) dependencies. Any thought why was that? Thank you.

Updating gfortran in CentOS 5.4?
by Jon Forrest 04 Feb '10

04 Feb '10

We're finding that several of the packages we need don't compile using the version 4.1.2 of gfortran that comes with CentOS 5.4. So, I've built the latest version of gfortran (e.g. 4.4.2) but I've done it so that all the new version's files go in /share/apps/gnu so that they don't interfere with the standard gcc distribution (building gfortran requires building some parts of gcc). Although I can compile and run a simple fortran "Hello, world" program using the version of gfortran I built this way, trying to run a more complex application, such as charmm (a molecular dynamics program), fails. When I run charmm, I get the message "Killed". Running strace ./charmm shows execve("./charmm", ["./charmm"], [/* 43 vars */] <unfinished ...> +++ killed by SIGKILL Since "Hello, world" compiles and runs, but charmm compiles and doesn't run, there's something wrong with how charmm is linked. Also, although the 'file charmm' command shows an ELF 64-bit dynamically linked file, 'ldd charmm' says " not a dynamic executable" (note no file name). So, something is strange. What have other people done about building new versions of gfortran on CentOS 5.4? Is this worth the trouble? Or, is it better to just go with Intel Fortran?

atime, relatime query
by Rajagopal Swaminathan 04 Feb '10

04 Feb '10

Greetings, I am aware that mounting filesystems with noatime option greatly increases speed. I have tried to follow discussion on the pros and cons of using noatime. I have however not been able to mount with the option relatime in centos 5.2. But in a production db server, which is backed up by HP DP, is it advisable to mount with noatime? Anybody care to share their experience on it? Regards Rajagopal

subversion 1.6.9 and sqlite 3.6.22
by Benjamin Franz 03 Feb '10

03 Feb '10

I'm in the process of setting up subversion and since the version packages with C5 is, shall we say, showing its age, I've built an updated version. In order to do that I had to upgrade sqlite from the default 3.3.6 (which the current subversion will not build with) and I went with 3.6.22. Has anyone else had any experience with whether or not that breaks anything? I'm a little nervous because sqlite is used all over the place (rpm, X11, apache, yum, selinux, system-config-*, various perl modules, gnome, gimp, php, and so on). -- Benjamin Franz

Good > luck. > Hi Brent, Thanks for taking the trouble to reply to me personally. I'm using CentOS 5.3 on my PC simply because that's the latest version which I had downloaded and burnt to CDs! I'm afraid I'm a bit slow in keeping up with the fast-moving development of CentOS and am always a bit reluctant to rebuild/reinstall the operating system on my PC. However, I thought that 5.3 was sufficiently up-to-date for my purposes, but was disappointed when I found that neither the wifi on my laptop nor skype on my PC worked properly! I'm now using Ubuntu 9.04 on my laptop which seems to work brilliantly and is very user-friendly. I'm thinking of using Ubuntu (server edition?) on my PC, after years of using RedHat and CentOS, because as a 'semi-tech' user (and great supporter of linux) I do like the user-friendliness of Ubuntu!

Logrotate in CentOS 5.4 more brutal (to httpd at least) than in 5.3?
by Christopher Thorjussen 03 Feb '10

03 Feb '10

I've just updated a few CentOS 5.3 servers to 5.4. One of them were a Apache Webserver. Doing a diff/check on the new ".rpmnew" config files that are made, I saw that the logrotate command for apache was changed. In 5.3 it did a reload, but in 5.4 it does a hard kill: CentOS 5.3: /var/log/httpd/*log { missingok notifempty sharedscripts postrotate /sbin/service httpd reload > /dev/null 2>/dev/null || true endscript } CentOS 5.4: /var/log/httpd/*log { missingok notifempty sharedscripts postrotate /bin/kill -HUP `cat /var/run/httpd.pid 2>/dev/null` 2> /dev/null || true endscript } Isn't this a bit harsh in 5.4? Wouldn't the 5.3 method be better? -Christopher Thorjussen

VMware Workstation 7.0.x and CentOS 5.4
by Akemi Yagi 03 Feb '10

03 Feb '10

VMware Workstation 7.0.1 Release Notes has a list of supported OS: http://www.vmware.com/support/ws7/doc/releasenotes_ws701.html According to that, RHEL 5.4 is listed as supported for both host and guest but CentOS 5.4 is only for guest. This is quite strange and, if it is true, that could be a serious issue. If you have VMware Workstation 7.0.x, could you tell us what you find? Did you encounter any problem when running CentOS 5.4 as a host? Thanks to nikkilocke who reported about the above release notes in the CentOS forum. Akemi
