samsung sata disk pb
by David Amiel 08 Mar '09

08 Mar '09

Hi there, I'm running a centos 5.2 (with a centos 5.3 kernel) on a box with a samsung 1To green edition, and this disk looks a bit slow to me and it's not recognized by hdparm : # hdparm -iI /dev/sda /dev/sda: HDIO_GET_IDENTITY failed: Invalid argument HDIO_DRIVE_CMD(identify) failed: Invalid argument # hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2252 MB in 2.00 seconds = 1125.57 MB/sec Timing buffered disk reads: 94 MB in 3.05 seconds = 30.81 MB/sec I've got a samsung 640go on my desktop running ubuntu (kernel 2.6.27-11), hdparm -iI is working and benchmark is a lot better : $ sudo hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2392 MB in 2.00 seconds = 1196.00 MB/sec Timing buffered disk reads: 226 MB in 3.02 seconds = 74.81 MB/sec the green HD is a 5400rpm, though the other one is 7400rpm, but a factor 2 in performance between them looks very strange to me. As the green 1 To disk is not identified by hdparm I think it's not configured properly. Any hint to make my 1To disk flying like the other one ? :) cheers, David

I have a test system that hangs hard...
by Robert Moskowitz 08 Mar '09

08 Mar '09

I have a test system: Centos 5.2 on an OQO, that has been hanging hard. I have to unplug it and pull the battery so I can then cold start it. This last time all I did was open a terminal window and SU to root, then start the lastest build of SIP Communicator (which uses JRE 1.6.0_10). I was not even making a test phone call at the time. Oh, and the system only runs IPv6, no v4 addressing. So how do I find out what is causing the hard lockups?

Please test kmod packages for CentOS-4
by Akemi Yagi 08 Mar '09

08 Mar '09

Hello, There are currently 3 kmod packages in CentOS-4 that require re-installation upon each kernel update: kmod-drbd kmod-drbd82 kmod-xfs CentOS is going to offer a kernel-independent version of these kmod packages. With this version, you install once, and they should survive kernel updates. They are in the testing repository at the moment and need to be tested before they can be made available from the regular place (extras repo). Getting enough testing is important because CentOS may not be providing kernel-specific kmod-packages any longer. If you have never used the testing repository, please refer to the Wiki article: http://wiki.centos.org/AdditionalResources/Repositories Happy testing! Akemi

topbanel and bottompanel on gnome
by Jerry Geis 08 Mar '09

08 Mar '09

I am doing the following commands to "hide" the top and bottom panels on gnome. gconftool-2 -t int --list-type int --set /apps/panel/toplevels/top_panel/auto_hide_size 0 gconftool-2 -t bool --list-type bool --set /apps/panel/toplevels/top_panel/auto_hide true gconftool-2 -t int --list-type int --set /apps/panel/toplevels/bottom_panel/auto_hide_size 0 gconftool-2 -t bool --list-type bool --set /apps/panel/toplevels/bottom_panel/auto_hide true When I do this I still see 1 pixel worth of panel after it hides. How do I get rid of that 1 pixel (it looks like a line at the top and bottom of my screen). Or better yet how do I completely disable the top and bottom panels using gconftool-2? Thanks, Jerry

Mail delivery failing with 450
by James Pifer 07 Mar '09

07 Mar '09

I'm not sure why this started, but apparently I'm having a DNS problem. Yesterday mail started bouncing with this error: 450 Unable to find obrien-pifer.com I think the messages eventually get delivered, but not sure. I guess I'll see if this one makes the list. I checked my domain using http://www.checkdns.net/ and it gives me a couple warnings. One is that there's no MX record, but there is. I use a smarthost for sending mail. My DNS records are: http://www.obrien-pifer.com/mydns.txt Anyone see any problems in my DNS records? Thanks, James

If possible, can SIP Communicator be configured to use IPV4 instead of V6? If so, does the problem persist? > So how do I find out what is causing the hard lockups? > I'd start with enabling IPV4 addressing since it's fairly trivial to do and then work back toward running an earlier version of the program. You may find something like the JRE wants an IPV4 connection (just wildly speculating here). Cheers, Dave -- Politics, n.

Easiest way to get samba up and working for Windows users?
by Noob Centos Admin 07 Mar '09

07 Mar '09

Everytime I have to setup samba to handle Windows users, sometime inadvertently goes wrong or doesn't work the way I expected, or takes forever to setup, especially when there are many users and various policies. So far, the easiest, sureest and quickest method appears to be install WindowsXP into VMWare and use it to handle Windows sharing. Needless to say, this strucks me as rather ironic and stupid. Thus could anybody please suggest a working frontend to samba that makes it easy to add users, set their permissions and get something that works like basic windows file sharing? So far I've tried the following which all don't quite work. 1. CentOS's samba configuration tool - added users never show up on the share configuration so the only shares it could create was for public access. 2. Webmin - thinks it added the users, but again they never show up when checked against the bundled CentOS tool and needless to say, the shares never work too 3. Samba SWAT - Very confusing tool, selecting shares sometimes end up as another share, and again, doesn't seem to work. So I just need a very basic tool that will reliably allow me to do the following - specify user name, specify password, and maybe specify a group - specify a share the user or group has read only or read/write access - force new files/folders to take on group ID so that it behaves like a normal windows share Don't need print services or anything, it's just far easier to dump a hardware print server into the network than to contemplate the additional complexity of making something like CUPS work. Just need to make sure that the Windows users can browse to the folders, get a prompt for their login and password where needed. Thanks!
