RedHat

Getting started with RHEL4's built-in LVM tools

Post date: June 3, 2005, 16:06 Category: System Views: 6112 Comments
Tutorial quote: Many Unix administrators I know (you know who you are), always used to smirk when I talked about Linux. They could always point to the fact that regardless of whatever I could say, they had journaling file systems, which they could manage using various Logical Volume Management (LVM) tools, and I couldn't touch that.

Well, not any more! Not only does Red Hat offer ext3 as their default file system, but they offer great management tools to boot. As we know, ext2 had a great lifespan, but it was not an enterprise-ready file system that could handle large disk partitions, fast recovery from systems crashes, or large amounts of files. Journaling file systems give you the ability to recover almost instantly from a crash, as you do not need to run fsck after a restart. Similar to how databases recover from crashes, a journaling file system tracks changes to file system metadata and pretty much guarantees that either all or no updates have completed. Of course, these file systems also need elaborate tools to help better configure and manage them accordingly.

The PartImage Handbook

Post date: May 21, 2005, 15:05 Category: Software Views: 2573 Comments
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.

Change your Network card MAC ( Media Access Control) address

Post date: December 4, 2007, 10:12 Category: Network Views: 3077 Comments
Tutorial quote: Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

If you want to change your network card mac address you need to use simple utility called mac changer.MAC changer is a utility for manipulating the MAC address of network interfaces
