Hello, On the Intel Core 2 Duo processor based systems, we have the option of installing either x86_64 or the i386 distribution. I would like to know your experiences with the x86_64 port. How does it compare with the i386 distribution in terms of stability, reliability and performance ? How significant are the performance benefits gained by using the x86_64 linux instead of i386 on the same

Has anyone created or rebuilt a Linux Software RAID having mirrored partitions on unequal sized hard disks ? There is a CentOS 5 server having two 400 GB hard disks with five mirrored partitions (software RAID 1) and one of the hard disks is dying. Since new 400 GB HDDs are not available here, we are exploring the possibility of replacing the faulty hard disk with one of a higher capacity (500 GB

Hello, Is there any command / option available on CentOS to expire a user's password immediately ? I remember using "passwd -e" on some other distribution but the -e option does not seem to be present on CentOS 5.x. Thanks, Manish

I have a doubt. If you use such a script monitoring the link status with ping and then reconfiguring, why do you need the DGD patch? You need to do some reconfiguration (change multipath to a single default route) anyway if you use the script, right? Also, the DGD patch uses src to lookup the routing table entry, but if you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this approach

Hello! I read the Split access and Load balancing sections into LARTC (Chapter 4). However I have one gateway only and the LARTC says about 2 links. I need to know how to make a load balance with my links. Thanks in advance. Eriberto - Brazil

Hello, Does CentOS 5.4 support large ( > 2 TB) external storage devices using GPT (GUID Partition Tables), while the main OS resides on smaller hard disks using MBR. In this scenario, what can be the largest possible size of an ext3 partition (and filesystem) which can be created on the storage array under CentOS 5.4 ? Thanks, Manish

I have recently installed CentOS 6 on a system with a Realtek 8180L wireless card. The wireless card is detected properly and uses the rtl8180 driver. But it connects to our wireless network only after logging to the Desktop Environment (GNOME) and using the Network Manager Applet. In order to make the wireless card connect to the network automatically at system start up, I edited the Connection

Are the RPMs for the latest GFS kernel module GFS-kernel-2.6.9-72.2.0.8 to be used with the version 2.6.9-55.0.9.EL available ? I tried to compile the Source RPMs available from the Red Hat site but the modules can't be loaded because of invalid module format arising from version magic issues. The syslog shows: node0 kernel: gfs: version magic '2.6.9-55.0.9.ELsmp SMP 686 REGPARM

Hello, I had installed CentOS 5.0 on my desktop PC having a Realtek 8180L based PCI wireless card. Since the drivers for this chip are not available in the kernel, I created RPMs for ndiswrapper-1.43 from the source code and installed them. I could configure the wireless card and use it but invariably the system freezes after sometime. No such thing happens if the wireless card is disabled. In

How are the updated kernels released by Red Hat / Cent OS related to the latest vanilla kernels ? Are the changes, new features and drivers, etc. available in the newer kernels also ported to the updated kernels released by Red Hat in their entirety ? For the lifetime of a distribution like RHEL 4 or RHEL 5, Red Hat would stick to the same major and minor number of the kernel and would just

What is the maximum number of nameservers mentioned in /etc/resolv.conf which will be queried while looking up a hostname or IP address in the present version ? Earlier implementations had a ceiling of 3 name servers which could be queried. Has there been any increase ? Thanks, Manish

I am facing problems assigning the owner and group to an ext3 filesystem being mounted from an external storage. I created a mount point /vol and changed its owner and group to alpha and beta respectively (as required). The ext3 filesystem (LV from the external storage) was then mounted on /vol using the mount command. However, after mounting the filesystem the owner and group of /vol changed
