yum update perl error in CentOS 5.3

03 Apr '09

Hello, if running 'yum update' on a CentOS 5.3 workstation, that was upgraded from CentOS 5.2, I run into the following error with perl.

I am booting 5.3 on an a770 biostar motherboard THe machine boots, I get the prompt from the DVD I hit return and the screen says kernel alive but it never gets past that. I tried booting again with noprobe on the command line same thing. I tried booting again with noprobe and noapic nolapic and same thing. Any thoughts on how to get past the halting?? Thanks, Jerry

suggestions on other packages
by Jerry Geis 03 Apr '09

Hi all - Since upstream patches the stock 2.6.18 kernel into something that is not 2.6.18 (for the rest of the world) I am having issues trying to compile some packages like v4l (latest is needed for a different project). When compiling packages like v4l that a doing conditionals based on kernel number - but - header files are messing other things up... is there some great trick to getting things to compile or behave nicely? What do others do in this circumstance? Note: If I did compile a kernel (2.6.17.10 for example) v4l works fine. however then I am not getting kernel updates with releases etc... Thanks, Jerry

dm-ioband RPM packages
by Ryo Tsuruta 03 Apr '09

03 Apr '09

Hi all, This is a good news for LVM users, especially for RHEL and CentOS users. You can control I/O bandwidth of your disks easily without hassle, because I've made RPM binary packages of dm-ioband and dm-ioband-config available at http://people.valinux.co.jp/~ryov/dm-ioband/binary.html The RPM binary packages are for Red Hat Enterprise Linux 5.x and CentOS 5.x. They were tested on CentOS 5.3 and will also work on other 5.x versions. Please refer to the on-line manual at http://people.valinux.co.jp/~ryov/dm-ioband/manual/index.html or the README file which is installed into /usr/share/doc/dm-ioband-VERSION for usage information. The dm-ioband-config package provides a configuration file and an init script to make it easy to assign bandwidth to LVM logical volumes. The merits of using this are the followings: - I'm sure you can use this script without any efforts since most of modern Linux distributions already make filesystems on LVM logical volumes. - You can enable and disable dm-ioband anytime you want. No need to modify any configuration files which refer to the logical volumes, because enabling/disabling dm-ioband doesn't make any changes to device names and numbers. - You can apply dm-ioband to a root device even if it is already mounted. The following diagram shows how dm-ioband is applied to the existing logical volumes. run "service ioband start" ===> ------------------------------- ------------------------------- | LogVol00 | LogVol01 | | LogVol00 | LogVol01 | | (dm-linear) | (dm-linear) | | (dm-ioband) | (dm-ioband) | |-------------------------------| |-------------------------------| | VolGroup00 | | LogVol00-orig | LogVol01-orig | ------------------------------- | (dm-linear) | (dm-linear) | |-------------------------------| | VolGroup00 | ------------------------------- <=== run "service ioband stop" Thanks for the device mapper infrastructure, any device mapper modules can be dynamically pushed into kernel or replaced with other modules anytime. Please refer to the README file at http://people.valinux.co.jp/~ryov/dm-ioband-config/README.txt or which is installed into /usr/share/doc/dm-ioband-config-VERSION for usage information. Any comments and suggestions are welcome! Thanks, Ryo Tsuruta dm-ioband is an IO controller which provides disk bandwidth control to Linux. It can controls bandwidth on a per partition, per user, per process basis and so on. If you use dm-ioband in a virtual machine environment, you can control bandwidth on a per virtual machine basis.

Can't connect to network even with no security. Is this possibly a firmware issue?

I can't seed > at home anymore for some reason... 8-/ Mine limits me to 40k up - leave it running long enough though, and it is easy to give back several times what you took. As far as home networks, I found that when I was running NAT on Linux (RH8 through FC2 days) - bt really screwed up my home network. However, when using hardware routers, even the cheap consumer kind (Linksys) the home network is fine. I think bt is very hard on software routing.

Centos 5.3 - NetworkManager applet
by Robert Moskowitz 03 Apr '09

03 Apr '09

So far I have upgraded 2 test laptops (no big servers or this, my main laptop). I am running from local repos. The OS repo is from downloading the isos and extracting them. The Update repo I get with an rsync command. On both laptops, the update ends with a dialog panel (oh, I am using gnome): The NetworkManager applet caould not find some required resources. It cannot continue. I don't see anything in /var/log/messages that might shed light on this. On both these systems, I have the NetworkManager deamon disabled. I was able to start it in a terminal window with the services command and it seems to have worked; I see the icon on the system tray. Meanwhile, going through messages I see a message at the end of the bootup about nm-system-settings about loading plugin ifcfg-rh. First it parses ifcfg-lo and then notifies that it is ignoring the loopback device config. It then goes on to read ifcfg-eth0 (which is set for ONBOOT=no, so nothing more happens). So is this dialog a 'bug' or just an artifact of upgrading from 5.2 to 5.3?
