There are plenty of reasons why people would need to encrypt a partition. Whether they're rooted it in privacy, security, or confidentiality, setting up a basic encrypted partition on a Linux system is fairly easy. This is especially true when using LUKS, since its functionality is built directly into the kernel. Installing Cryptsetup ...
If you often mount and access a remote NFS share on your system, you will probably want to know how to improve NFS file access performance. One possibility is using file caching. In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such as NFS. FS-Cache is built into the Linux kernel 2.6.30 and higher. ...
From 2daygeek.com Server patching is one of the important task of Linux system administrator to make the system more stable and better performance. All the vendors used to release security/vulnerabilities patches very often, the affected package must be updated in order to limit any potential security risks. Yum (Yellowdog Update Modified) is RPM Package Management utility for CentOS and Red Hat systems, Yum history command allows administrator to rollback the system to a previous state but due to some limitations, rollbacks do not work in all situations, or The yum command may simply do nothing, or it may remove packages you do not expect. I advise you to take a full system backup prior to performing any update/upgrade is always recommended, and yum history is NOT meant to replace systems backups. This will help you to restore the system to previous state at any point of time. n some cases, the hosted applications might not work properly or through some error due to recent patch updates (It could be some library incompatibility or package upgrade), what will be the solution in this case? Get in touch with App Dev team and figure it out an issue creating library' and packages then do the rollback with help of yum history command. ...

Last weekend I had a small weekend project to move my All-In-One Printer/Scanner from my Xen host server to a spare NAS200 I had lying around. Since the NAS200 has a i486 compatible CPU, and I had been able to run a CentOS 5 distro before, I figure it would make a good server with low power consumption. For that I updated my NASCC firmware so that it would boot a USB key, and update my CentOS image creation script. This worked well, I was able to boot CentOS without that much effort altogether. I myself have an Epson Stylus CX5500 which unfortunately only comes with binary drivers. This was not much of a problem since the NAS200 has a i486 compatible CPU. I find this is relatively unique among different NAS models. Alas, the performance was quite disappointing. I should be used to the NAS200 underperforming. But really, this was truly sad. I did not bother to test the printing, but I did try scanning with it. Running scanimage to scan a single page was taking over 15 minutes before I hit Ctrl+C. It was an idea, but the results were so sub par. The only take-aways of this are: ...
In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such as NFS. FS-Cache is built into the Linux kernel 2.6.30 and higher. In order for FS-Cache to operate, it needs cache back-end which provides actual storage for caching. One such cache back-end is cachefiles. Therefore, once you set up cachefiles, it will automatically enable file caching for NFS shares. ...
