gspca and motion
by m.roth＠5-cent.us 27 Jun '13

27 Jun '13

We recently rebooted a lot of systems with the new kernel in 6.4, 2.6.32-358.11.1.el6.x86_64. Suddenly, we're having real problems with our cheap surveillance cameras in the "computer labs". What I see of video and jpg is only about 20%-25% of the top of the picture, and the rest is green. When the service starts, I see, in both dmesg and /var/log/messages, gspca: bandwidth not wide enough - trying again And they worked fine before. Anyone else seeing this, or have some thoughts on how I can attack the problem? The most recent post with this error I can find is from '10, and isn't really relevant. Oh, and at least one's on a Dell R420, I think, while another's on an old Penguin, an Altus 1300, I think, so it's not specific to one set of hardware. mark

CentOS 6 SFF motherboard or complete system
by Glenn Eychaner 27 Jun '13

27 Jun '13

I am trying to assemble or purchase a set of CentOS 6 compatible SFF workstations, and am finding it incredibly frustrating to do so. hardware.redhat.com is so slow as to be useless and provides almost no information about each of the 1,300 or so products listed in their database; clicking through them one at a time is incredibly frustrating (and about half of them are discontinued or out of stock when I actually go looking for them, like the Intel DQ series motherboards I was interested in). Vendor web sites are almost no use; they trumpet their Windows 8 compatibility all over the site, but finding information about Linux compatibility is next to impossible. My requirements aren't overwhelming; an i7 processor, four memeory slots preferred, dual 24" (1920x1200) monitor capability, and dual ethernet (or an expansion slot for a second Ethernet card). Anyone have any advice on how to attack this these days? I've been out of the hardware-purchase game on the Linux side for years, and most of my bookmarks no longer point anywhere useful, sadly. -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

Server hangs after installing KVM
by Guy Boisvert 27 Jun '13

27 Jun '13

Hi, I just received a Supermicro server back from factory repair. Installed CentOS 6.3 x86_64 fresh from DVD (tried with 6.4, same result). Everything goes fine until i install Virtualization* yum groups. Virtualization is enabled in BIOS. Server boots, CentOS loads and i have even a login prompt. If i'm fast enough to enter login name and password, shell works for about 10 sec. Then, it seems to hang. Pressing CTRL-C seems to work as i see it on screen (CTRL-C text). I'm used to Xen in CentOS 5 where we can choose a non-Xen kernel at boot time. With CentOS 6 and KVM, i'm kinda lost! I Googled a lot and didn't find anything to disable KVM / select a a non-KVM kernel a boot up time. The server has been repaired but i'm not sure if there is still other problems that prevent KVM to work. I know that they installed the last BIOS version. I have other identical servers that works well with KVM. I tried to disable all i saw for virtualization support in BIOS, result is the same. I did memtest86 tests without problem. Here are the specs: Supermicro 6026T-3RF (mainboard X8DT3-S) BIOS 03/17/12 15:50:21 Ver 2.1 Xeon E5520 Kingston 12 Gig RAM (Triple Channel) LSI 9240-8i What should i do to debug this? Any pointers, URL, etc would be greatly appreciated! Thanks all. Guy Boisvert, ing. IngTegration inc. http://www.ingtegration.com

Http tunnel via a http proxy to another http proxy server
by Heng Su 27 Jun '13

27 Jun '13

Hi All, Is that possible create a http tunnel to remote http tunnel server via a middle http proxy? Here is my situation : My Company only allow http protocol and they created a http proxy server. So when we want to access internet we have to set the http proxy settings for the browser or application. Now I want to access outside without restrictions of http protocol and also not limited to 80 port. As they blocked the ssh, so the SSH reverse binding is not possible. So is that possible to create a http tunnel via the http proxy of my company and aim to my own server outside? Or there is any other good idea? Thank you very much. -- Thanks & Best Regards, Su Heng

I kicked out VMWare and their "Windoze" tools i hate (i know that now they offer a VM with command line tools). I'm not saying VMWare is not good though, it's just i hate their tools. On top of that, it can cost a lot of money. But they have the features! I moved to KVM and i'd say i like it a lot. I'm planning to test OpenStack. For storage, big names (3Par, Netapp, etc) offer nice things but it is rather expensive. I'm testing iSCSI servers with DRDB, STONITH, etc. Idea is to use commodity hardware and standard software. Nothing new and i'm not against commercial solution with support and all. It's just we try to offer affordable and open solutions.

15 min pause during boot - Setting up logical volume management
by aurfalien 27 Jun '13

27 Jun '13

Hi all, I rebooted a server having a 20TB XFS volume under LVM and wait about 15 min to boot. It stays at; Setting up logical volume management For 15 min then proceeds to boot fine. During this time, I see the 14 disks of the 20TB volume flashing quickly as though being read. Nothing in my logs to indicate bad behavior. I am running the latest 6,4 kernel. Any one see this before? - aurf

No more support for chrome/chromium on rhel6
by Robert Arkiletian 26 Jun '13

26 Jun '13

https://plus.google.com/u/0/100132233764003563318/posts/Y1s6T44Soby Not 100% this is true but the problem apparently is that rhel6 uses an old version of gtk2. If this is true, then it affects my school and my students. I like google-chrome and it works very well with google services. I was planning on using C6 for a long time. Does anyone know of a repo that intends to keep Chromium working for C6? -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

CentOS 6 guest OS does not detect reboot/shutdown signal from virt-manager
by Arun Khan 26 Jun '13

26 Jun '13

My setup is as follows: Host OS: Debian Wheezy amd64 stock kernel (3.2), virt-manager v0.9.1 Guest VMs: A bunch of Linux based servers - CentOS 6, Debian 6/7, Ubuntu 12.04 (all amd64 with stock kernel). All of them defined using virt-manager GUI interface. >From the virt-manager, I am able to shutdown/reboot the Debian and Ubuntu guest OSs but not the CentOS 6 guests. For the CentOS 6 guests, I have to resort to "Force off" I have looked at the syslog and messages log files but do see anything to correlate between host and guest OS. Any pointers on how to debug this problem would be much appreciated. Thanks, -- Arun Khan Sent from my non-iphone/non-android device
