CentOS 5 on a Thinkpad T60 laptop
Hello, I'm considering buying a second-hand Thinkpad T60 (with 2 GB RAM), as a secondary laptop in order to run CentOS 5 on the field. My main focus is therefore to have something robust, reliable and above all well compatible with CentOS. Hibernate / suspend feature are important to me, because that's the main issue I have with CentOS on other laptops. I have found the following

Firefox slower on GMail since update to CentOS 5.5
Hello, since I upgraded from CentOS x86_64 5.4 to 5.5, I noticed that Firefox has become significantly slower on GMail (or Google Apps Mail). The page becomes slow to scroll as soon as there are more than a few mails in a conversation (like in a typical CentOS mailing list thread). Did anyone else notice that as well? (I guess that I'm not the only GMail user around) Could I have missed

Eclipse Helios on CentOS 5.5 (was Websites Up!)
> Then I hope to finish my tutorial on installing Eclipse > Helios for Centos 5.5 Is there anything special to be done? I just unzipped the SR1 distribution for RCP/RAP developers linux-gtk-x86_64 and it works without problem on an up to date CentOS 5.5 x86_64. (to be more precise: I install it as root under /opt, install some plugins like subclipse and regular users start it from there)

Best practices for LVM and virtualization
Hello, I'm currently setting up a virtualization infrastructure based on CentOS 5.4 x86_64 and KVM. I want to use LVM because of its flexibility, especially the ability to add more disk space to a guest if needed. We are considering using an hardware RAID1 with BBU as the lowest layer. My question is: where is it recommended to put the LVM? 1. On the host only In that case, the guests

Internet access not working on CentOS but on Windows when travelling
Hello, I'm currently travelling (in south-eastern Europe) with a netbook (Samsung NC 10) running CentOS 5.4 i386. I frequently try to access internet from bars or hotels (mostly via wireless). Although it works pretty often, it happens quite regularly that in some hotels I cannot access internet from CentOS while it is possible from Windows. This is the case in the hotel where I am currently

Supsend/hibernate on Samsung NC10
Hi, I cannot have suspend and hibernate working on a Samsung NC10 (netbook) running CentOS 5.4 i386. When I try suspending/hibernating the screen becomes black (with a few logs, like "shrinking memory" for hibernate) and then the computer hangs and I have to force a shutdown with the power button. This wiki page seems to say that it should work out of the box:

CentOS, Firefox, and Java Plugin
The latest updates to CentOS 5.5 seem to have broken the Java plugin, and have defeated any and all attempts to get it working again. I'm running CentOS 5.5 (32-bit) and Firefox 3.6.9 (installed from the CentOS repository); I've tried BOTH the openJDK plugin available through the Argeo repositories, and installing Java 1.6.0 directly from Sun/Oracle and creating the plugin soft link in

CentOS 6 - Does EFI have an impact beyond the boot sequence?
Hello, I am using an up to date CentOS 6 x86_64 laptop (Thinkpad X220t) and after struggling a bit I could install it a few months ago with a pure EFI boot. However, I am not really satisfied with such things as stability, power consumption, etc. and now that I have a little more time I want to investigate these issues thoroughly. So, my questions are: - Does EFI impacts other things than the

Power consumption monitoring
Hi, I have quite a few low-end development/test servers running continuously and I would like to better manage their power consumption. I have found interesting information on how to perform CPU scaling (e.g. [1] or [2]). But I cannot find if there is a way to (software) monitor power consumption on CentOS (or other such data like CPU temperature, fan speed etc.). What I read so far is that

Having less languages in Firefox (hunspell dictionaries provide too many locales)
Hello, on CentOS 6, I am routinely writing mails in English, German and French and using the related hunspell dictionaries for the spelling in Firefox (I'm using Google Apps). This works fine but the problem is that languages are added for all the possible locales (English US, UK, Philippines, Bostwana, Trinidad and Tobago, Denmark (sic!), ... and German Germany, Austria... and French

Changing default paper size to A4 on CentOS 5 (Kyocera FS1920 printer)
Hello, I have a Kyocera FS1920 network printer, and I run an up-to-date CentOS 5.6 x86_64 workstation. When I try to print with evince or Firefox the default paper size is always set to US Letter whereas the printer use A4. I have searched and other people seem to have the problem, but the only recommendations that I have found boil down to setting the default paper size to A4 in the CUPS

CentOS build scripts (or equivalent) acessible?
from [CentOS] CentOS 5.4? anyone? > Is that a big problem for the people who write the code and have every > revision preserved for posterity (and for others to learn from) in a > public revision control system? > I'm not sure that I understand. Is there indeed such a public repository of the build scriptds / RPM specs used by CentOS? That would indeed be fascinating and useful

Subversion server: v1.4 (centos) vs. v1.6 (rpmforge)
Hi, I'm planning to upgrade an old public/internal development infrastructure and will use CentOS 5.4 x86_64 as basis. One of the critical server is Subversion (as an Apache httpd module). We currently use Subversion v1.4 on the server and v1.6 on our clients. While I was very happy with the v1.4 server over the years, we now sometimes have weird issues which seem related to compatibility

Problem when opening files after installing OpenOffice 3.1 on CentOS 5.4
Hi, I have installed OpenOffice 3.1 downloaded from the openoffice.org website on CentOS 5.4 x86_64. The downloaded file is actually an archive containing RPMs. I did not use their setup tool but installed directly the RPMs I was interested in via 'yum localinstall' (my idea is in the future to put them on a custom yum repository, so that they can be managed via regular yum install /

Hello, I have a central repository of users/groups based on OpenLDAP which is working on a remote LAN (servers share users credentials and mount their home directories via NFS). They use non-encrypted ldap restricted to the local network. Now, I have a few servers in our local office and I would like them to authenticate from the remote LDAP server using encryption via ldaps://. (at this stage,

IP based VirtualHost: IP aliases vs. additional virtual interfaces
Hi, I have a virtualized infrastructure based on KVM/QEMU with CentOS 5.5 x86_64 hosts and guests, using bridge networking. I want to set up IP based VirtualHosts in Apache (because they will use SSL) and I have ordered an IP block. Now, in order to have the IPs available on some guests, I'm wondering whether I should: 1 - add additional virtual interfaces or 2 - set up IP aliases (eth0:1,
