Migrate your Linux application to the Amazon cloud
Cloud computing and Infrastructure as a Service (IaaS) are well documented, but what's often not discussed is how to get a running application into a cloud computing environment. Discover how to move an application into the cloud and take advantages of the features this setup has to offer.
Virtio: An I/O virtualization framework for Linux
With all the virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization? The answer is virtio, which provides an efficient abstraction for hypervisors and a common set of I/O virtualization drivers. Discover virtio, and learn why Linux will soon be the hypervisor of choice.
Boot Linux on the Beagle Board
The Beagle Board is an open-hardware single-board computer that is both inexpensive and capable of running Linux at a reasonable speed. Get to know the Beagle Board, and learn how to get a Linux development environment together on the cheap./l-beagle-board/index.html?ca=dgr-lnxw07Beagle-Boarddth-LX&S_TACT=105AGx59&S_CMP=grlnxw07">Get to know the Beagle Board, and learn how to get a Linux development environment together on the cheap.
Postfix Backup MX eMail Server Anti-Spam Configuration
According to RFC2821 the lowest-numbered records are the most preferred MX for domain. So a target Postfix backup server is used to keep the messages in a queue waiting for the primary server to become available. This ensures that if my primary MX goes down you do not loss any emails. However, spammers are connects to backup MX to avoid anti spam filters that are running on the primary MX server. This also hides their real IP from my primary MX. This tutorial shows how to configure anti-spam and anti-virus for Red Hat / CentOS Linux ver5.3 based Postfix mx server.
Worry-free Linux power-downs with Anacron
Linux ordinarily uses Cron to automatically perform routine system maintenance on desktop or laptop computers, however not running Cron routinely can result in monstrously large log files and other problems. You can offload most or all of your usual daily and longer-interval Cron jobs onto Anacron enabling your computer to run regular maintenance jobs whenever the computer is powered on, even if those times are unpredictable.
The Squirrel portable shell and scripting language
If you don't want to commit to the idiosyncrasies of a specific shell running on a particular platform, try the Squirrel Shell. The Squirrel Shell provides an advanced, object-oriented scripting language that works equally well on UNIX, Linux, Mac OS X, and Windows systems. Write a script once, and run it anywhere.
Amazon cloud computing SimpleDB boto processing
Amazon SimpleDB (SDB) is a fast, scalable real-time dataset indexing and querying framework that makes it easy to store and retrieve structured data for Amazon Web Services-based applications in the cloud. In this article, learn some of the basic concepts of Amazon Cloud computing and check out some of the functions provided by the third-party open source Python library named boto. You will get familiar with Amazon Cloud computing and SDB by running small snippets of boto code in a Python shell.
Avoid virtualization overhead with Linux Containers
Linux Containers provide lightweight virtualization that lets you isolate processes and resources without the need to provide instruction interpretation mechanisms and other complexities of full virtualization. In this step-by-step tour of Linux container tools (LXC), the author introduces you to the Linux container tools and shows how to get up and running on them. This article will show you how Linux containers significantly lower the overhead of using true virtualization, while still providing isolation.
Linux buffer overflow issues on Power-based systems
Buffer overflows occur when a process tries to store data outside of the bounds of a fixed-length buffer. When that happens, all sorts of erratic system behavior can result. In this article, all examples of buffer overflow vulnerabilities in Linux running on Power/Cell Broadband Engine Architecture processor-based servers.
Install and Configure Nagios to Administer a Networking System
Nagios is a very powerful platform because it is easy to extend. The previous chapters talked about check command plugins and how they can be used to check any host or service that your company might be using. Another great feature that Nagios offers is the ability for third-party software or other Nagios instances to report information on the status of services or hosts. This way, Nagios does not need to schedule and run checks by itself, but other applications can report information as it is available to them. This means that your applications can send problem reports directly to Nagios, instead of just logging them. In this way, your applications can benefi t from powerful notifi cation systems as well as dependency tracking. This mechanism can also be used to receive failure notifi cations from other services or machines—for example, SNMP (Simple Network Management Protocol) traps. This is described in more detail in Chapter 9. Nagios also offers a tool for sending passive check results for hosts and services over a network. It is called NSCA (Nagios Service Check Acceptor). It can be used to send results from one Nagios instance to another. It can also be used by third-party applications running on different machines to send passive check results to a central Nagios server. This mechanism includes password protection, along with encryption, to prevent injection of false results in to Nagios. In this way, NSCA communication sent over Internet is more secure.
