Are you an experienced Windows system administrator who has just begun to work with CentOS or another Linux server distribution? With the help of the Webmin configuration tool you can perform your new sysadmin duties from a simple web interface.
If you routinely use multiple computers, it can be a challenge to keep your data files organized and to manage multiple login IDs. OpenSSH can help you with those tasks. It's a powerful, secure tool that lets you share files without having to set up a file server, run applications remotely, and perform remote administration chores quickly and securely. You probably already know how to use OpenSSH for file transfers. Here we'll uncover some less well-known OpenSSH tricks that can make life easier for roaming computer users.
Last month saw the release of CentOS 6. The move from 5 to 6 establishes the foundation for this community-run enterprise Linux distribution for the next five years. CentOS brings a new kernel, new versions of key server components, and improved virtualization support.
While you can install any software on the Linux desktop with just a couple of mouse clicks, enterprise apps are a different story, because they require a lot of infrastructure software, from high-end web and database servers to basic libraries. As a system administrator you may spend hours putting together components before you can deploy an app on the network. Fortunately, some convenient software tools can do the grunt work for you. Packages such as XAMPP, BitNami, Turnkey Linux, and JumpBox can help you deploy a new server app you've been wanting to try in no time. Some solutions install on bare metal, while others can install within a virtual machine, or even on a cloud-based hosting service such as Amazon EC2.
