Plus, they integrate the media server, so upnp/DLNA clients like the PS3/Xbox360 and an increasing number of network-connected TV's can view the same pictures with their built in protocol without yet another setup. -- Les Mikesell lesmikesell(a)gmail.com

That's *almost* what I want, except I want the directory listing to show the actual images instead of just links to the images.

RPM python subroutine for (epoch, version, release) comparation?
by Robinson Tiemuqinke 26 Jun '09

26 Jun '09

Hi, all, On Centos 5 I am programming RPM with python recently. When I read the online RPM python programming guide at http://docs.fedoraproject.org/drafts/rpm-guide-en/ch16s05.html, I got confused at the EVR() function as the function returns the (epoch, version, release) as a string “%epoch-%version-%release”, and so the RPM comparing process is simplified as string comparing – which doesn’t look correct, am I wrong? See the code from the page: -------------------------------------------------------------------------------------- file_h = ts.hdrFromFdno(fd) file_ds = file_h.dsOfHeader() inst_ds = inst_h.dsOfHeader() if file_ds.EVR() >= inst_ds.EVR(): print "Package file is same or newer, OK to upgrade." else: print "Package file is older than installed version." -------------------------------------------------------------------------------------- I’ve see another function in rpm object: rpm.versionCompare(h1,h2) which compare two rpm headers, Am I supposed to use this function or the EVR as documented? The former one is not well documented, though. Thanks. -- Robinson

CentOS 5.3; x11 lost keyboard
by George R Goffe 26 Jun '09

26 Jun '09

Howdy, I have an IBM thinkpad with it's "standard" monitor and keyboard. It's been connected to a larger monitor and usb keyboard and usb mouse. The xorg.conf is a dual head config. This has been working for a few weeks now but has started failing. During boot and subsequent login the keyboard and mouse (gpm started) and display (larger monitor) work fine. When I startx, the keyboard becomes "dead to the world". NO signals are sent from the keyboard as far as I can tell. I had just configured VNC server and made it start at boot time when this problem appeared. I am sadly in need of hints/tips/suggestions as to how to trouble shoot this problem. Thanks, George...

More awk help
by Joseph L. Casale 25 Jun '09

25 Jun '09

Hey guys, Looking through my book and the web and I am not having any success returning data from a search. I need to have awk search for a string and print the first field which is no problem but now its returning two options as the input data has changed. The change is reliable, I only want the first field if it ends in a regex that I have, and I only want what that regex matches to be printed. Is it possible to do this in a one liner so I don't need to construct an awk script? I suppose I could pipe it into grep and cut but that's not very sexy :) Any ideas? Thanks! jlc

Unexplained reboots in DRBD82 + OCFS2 setup
by Kris Buytaert 25 Jun '09

25 Jun '09

We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0 disk and mounting it on both nodes, basic functionality seems in place but usually less than 5-10 minutes after I start bonnie++ as a test on one of the nodes , both nodes power cycle with no errors in the logfiles, just a crash. When at the console at the time of crash it looks like a disk IO (you can type , but actions happen) block happens then a reboot, no panics, no oops , nothing. ( sysctl panic values set to timeouts etc ) Setting up a dual-primary disk , with ocfs2 only mounting it on one node and starting bonnie++ causes only that node to crash. On DRBD level I get the following error when that node dissapears drbd0: PingAck did not arrive in time. drbd0: peer( Primary -> Unknown ) conn( Connected -> NetworkFailure ) pdsk(UpToDate -> DUnknown ) drbd0: asender terminated drbd0: Terminating asender thread That however is an expected error because of the reboot. At first I assumed OCFS2 to be the root of this problem ..so I moved forward and setup an ISCSI target on a 3rd node, and used that device with the same OCFS2 setup. There no crashes occured and bonnie++ flawlessly completed it test run. So my attention went back to the combination of DRBD and OCFS I tried both DRBD 8.2 drbd82-8.2.6-1.el5.centos kmod-drbd82-8.2.6-2 and the 83 variant from Centos Testing At first I was trying with the ocfs2 1.4.1-1.el5.i386.rpm verson but upgrading to 1.4.2-1.el5.i386.rpm didn't change the behaviour Anyone has an idea on this ? How can we get more debug info from OCFS2 , apart from heartbeat tracing which doesn't learn me nothing yet .. in order to potentially file a valuable bug report. thnx in advance Kris

LinuxTag day One
by Didi 25 Jun '09

25 Jun '09

The guys [3] at LinuxTag want to share some of the stuff they have been doing today. After setting up the booth [1] we started the usual socializing by doing this, we met Brian Schueler again who created a PowerPC 32 version of CentOS and even a ARMv5. This is quite impressive and we all gathered around to see a little demonstration. Further we talked to the usual suspects from Fedora and Red Hat which was represented quite strongly this year. Nothing special about the booth [2] this time we have an iMac on display on which we are showing some information about CentOS. Then we went on dismantling a thinkpad to see how it looked on the inside and some members of the team visited some talks. We are now off to the pub for some food and German Beer. Cheers [3] [1] http://picasaweb.google.com/ribalba/LinuxTag09#5350925153100143234 [2] http://picasaweb.google.com/ribalba/LinuxTag09#5350925123075083122 [3] Chris, Chris, Dag, Didi, Tim ---- My www page: www.ribalba.de Email / Jabber: ribalba(a)gmail.com Skype : ribalba
