Hello, are there any best practices for the length of user names? I tend to limit them to 8 characters and to follow the pattern 'first letter of the first name'+'first 7 letters of the last name' (e.g. mbaudier). But people are sometimes frustrated with having their last name truncated and I wonder if limiting the user name to 8 characters is not a kind of superstition coming

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

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

> 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)

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

Hello, I was not happy with the power consumption of CentOS 6 x86_64 on a new Lenovo Thinkpad x220 Tablet and I worked on reducing it. I just wanted to share with the list one of the changes which gave me the most significant improvement.

Within the LVM volume are two NTFS partitions formatted by Win2k8. Issue: How can I mount this? I need to verify file existence and run batch of file compare checks. If I try to mount

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

I have a quad core server in which I want to run 4 virtual servers. On this server I have a 1/2 terabyte raid 1 I have split between the 4 members that have the OS on it. I have raid 5 10 terabyte internal storage running on a 3ware 9690a card. I want to share this storage between the servers without partitioning it.

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:

I have a dom0 machine running CentOS 5.4 with all the latest updates using Xen as my hypervisor. I am using Xen in part because this machine was set up prior to KVM being included in RHEL, and in part because KVM's network bridging configuration is not nearly as simple as Xen's. The dom0 machine is a headless Mac Mini and I do all of my VM management via virsh from the command line. I

Can anybody tell me if it makes a difference if domU''s have separate LVM volume groups? For instance, the Xen User Manual ( http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000000000000) says, when setting up a domU''s disks with LVM, to do a vgcreate vg /dev/sda10 Should each domU have it''s own volume group, or can all the domU''s share
