2way authentication for SSH?
by Rudi Ahlers 05 Feb '13

05 Feb '13

Hi, Does anyone know of a stable / working "2way authentication" system for SSH, and even web authentication services? Most of the banks in South Africa have a system that, when you want to make a payment, they send you an SMS and you need to verify the action with a secret code which was SMS'd to you. gmail also has this. Does anyone know of a "universal" plugin / application that can be used with SSH and even websites like Wordpress / Joolma / Webmin / etc? Any pointer would be appreciated. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Cell: 082 554 7532 Fax: 086 268 8492

pymol
by m.roth＠5-cent.us 05 Feb '13

05 Feb '13

Anyone familiar with pymol? We're getting an error I find references to from a few years ago when we try to run remotely on a headless server. I can run it fine on my machine (CentOS 6.3, NVidia video), and on another person's workstation remotely, with other make video, but the server's got a Matrox - which shouldn't matter, since I'm running this after ssh -Y. pymol yum installed fine, no problems. I found, and did a export LIBGL_ALWAYS_INDIRECT=1, which allowed glxgears to work, albeit slowly and unevenly, but pymol always gives me freeglut (pymol): ERROR: Internal error <FBConfig with necessary capabilities not found> in function fgOpenWindow X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x0 Serial number of failed request: 24 Current serial number in output stream: 27 PyMOL: abrupt program termination. I read that this is two errors, not one, but other than the environment variable, can't find any other fix. Anyone? mark

CentOS on IBM Z Series.
by Rafał Radecki 05 Feb '13

05 Feb '13

Hi All. I manage some IBM Z Series servers. But currently there are no system tools (like OMSA tools for Dell servers) installed. Is there a repository with tools/firmware updates for IBM servers for Linux/RHEL/CentOS? I've googled around but with no luck. I have found only this for power servers: http://www-304.ibm.com/webapp/set2/sas/f/lopdiags/yum.html Best regards, Rafal Radecki.

recent ruby packages?
by m.roth＠5-cent.us 05 Feb '13

05 Feb '13

Does anyone know of a repository that's *trustworthy* (gotta worry 'bout malware) with newer ruby rpm's than RHEL has? OT: the more I deal with ruby, the less I like it. Someone here was ready to move to a newer version, and from the ruby.org website, they're apparently actively hostile to all RH-related distros, even though we're the most common in North America. They've got a how to do it from debian and arch, how to use their own installer, and, oh, yes, they say a lot of their community feels you should build from source. Sorry, that's not my idea of a stable language that I'd ever recommend to someone.... mark

Java app not observing ACLs
by Nikolaos Milas 05 Feb '13

05 Feb '13

Hello, I have inherited a Java app, available as a jar, which has been moved from an HPUX server as is. [This app simply downloads a data file from an ftp server, processes its data and creates graph files.] It works fine on a CentOS 5 x86_64 machine with: jre-7u9-linux-x64.rpm but I've noticed it does not respect Linux ACLs. When run by a user who has access to a directory (where the app creates a file) only via ACLs (and not by basic user/group permissions), then I get "permission denied" issues. I've googled for the problem but have not been able to find references. Is anyone aware of such behavior and can suggest a solution? Thanks, Nick

As the man says, Ruby is open source. If you have an itch then scratch it yourself. I had much the same issue with Ruby albeit on three platforms simultaneously, MS-Win, Apple-OSX and RHEL-Linux. In the end I went with Ruby Version Manager to save my sanity. However, RVM is a very intrusive bit of environment scripting and so I later switched to RBENV. That is a little lighter but I was still not satisfied with the amount of background work required to get Rails deployments to work with RVM/RBENV on different hosts. For development either RVM or RBENV is almost certainly the way to go for non-sysadmins. For deployments I am not so sure. I ended up building my own rpm packages using rpmdev and mock. After avoiding the issue for years I discovered that rolling your own rpms for Ruby is pretty simple, once you get a working spec file (which I eventually discovered and stole). If you care to go down that road I have provided a write up (spec file included) online at: http://byrnejb.wordpress.com/2013/01/30/building-ruby-1-9-3-for-centos-6-3/ > > Sorry, that's not my idea of a stable language that I'd ever recommend > to someone.... > > mark Yeah, well I can recall spending weeks on the phone with HP's tech response centre in Raleigh trying to get Cobol II to work as documented. Nobody asked me for my recommendation either. As for providing the packages, I am willing to send them to whoever wishes to host them. Even to CentOS extras if anyone would be kind enough to guide me through the administrative procedure to do so. -- *** E-Mail is NOT a SECURE channel *** James B.

intel_iommu=on => No root device found
by Nils Caspar 04 Feb '13

04 Feb '13

Hi all, for some reaseon, my message wasn't published. Second try, this time without the giant attachment. I have an Intel server (SR2600URBRPR) in front of me. The disks in my server are connected via PCI card (Adaptec RAID 3405). Now I would like to passthrough a PCI-E graphics card to a KVM guest. As this requires Intel VT-d, I configured the following options in the BIOS: Intel VT for Directed I/O [Enabled] Interrupt Remapping [Enabled] Coherency Support [Disabled] ATS Support [Enabled] Pass-through DMA Support [Enabled] Everything works so far, but when I add intel_iommu=on to the kernel line of my grub.conf, Dracut gives my a kernel panic while booting. I added "rdshell" to the command line and extracted the boot messages via dmesg (http://nilscaspar.ch/centos-dmesg.log). I think the main problem is this: dracut Warning: No root device "block:/dev/disk/by-uuid/280234d1-dff5-4e04-b1ef-93d54cdcd825" found But I doesn't make sense to me... As soon as I remove intel_iommu=on, everything works again (except the passthrough :P). Regards, Nils -- nilscaspar.ch

The moving of VNC port from 580n to 590n
by Robert Moskowitz 04 Feb '13

04 Feb '13

On my 'older' systems that include Centos 5.5 and Fedora 12, vncserver is running on ports 580n where n is defined by userid in the /etc/sysconfig/vncserver I just spent a bit of time getting it working on my new Centos 6.3 server and found it listening on ports 590n. When did the change occur? And guess I should test out where it is on Fedora 17...

weird issue with qemu-kvm network...
by skull 04 Feb '13

04 Feb '13

Hello CentOS mailinglist I am running CentOS 6.3 with qemu-kvm and libvirt. I was experimenting with bridged VM networking. Usually the VMs run over the network device virbr0. So i created a new bridge with brctl and added my eth0 to that bridge. Not touching virbr0 or it's configuration at all. Then i edited the configuration xml from my VM with 'virsh edit vmname'. After that i decided to restart my server, basically just to 'reset' my network. I know, that's not necessary. But it's easier than risking connection loss and having to get physical access to the server ;) After the restart my virbr0 network device was gone! cat /var/log/dmesg | grep virbr0 returned nothing. cat /var/log/messages | grep virbr0 brought up nothing aswell. I tried to reinstall all relevant packages with yum reinstall qemu-kvm python-virtinst virt-top virt-viewer libvirt libvirt-client libvirt-python qemu-kvm-tools But with no success :( Does anyone have an idea how to recreate the default virbr0? Is it doable via virsh? I don't have a DE installed on this server, so no virtual-manager. I am willing to go that far if it's worth it though.
