Many times, you want to execute a command not only on one server, but also on several servers. For example, find out * Version of kernel * Version of Apache web server * Update static html or images files on all web servers via rsync * Find out user information, server information, memory usage etc * Security/patch checking tentakel I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.

A good way to see how your Web applications and server will behave under high load is by testing them with a simulated load. We tested several free software tools that do such testing to see which work best for what kinds of sites. If you leave out the load-testing packages that are no longer maintained, non-free, or fail the installation process in some obscure way, you are left with five candidates: curl-loader, httperf, Siege, Tsung, and Apache JMeter.

Pootle is a user-friendly web portal that makes the translation process so much simpler. It allows online translation, work assignment, gives statistics and allows easy volunteer contribution. You can run Pootle as an Internet server like these projects or run your own copy on an Intranet (for individual work, team work or Translate@thons). Pootle makes use of the Translate Toolkit. Together, these tools are part of our project to make translation easier and of higher quality by creating better tools and user-friendly, central information.

djbdns is a very secure suite of DNS tools that consists out of multiple parts: dnscache, a DNS cache that can be used in /etc/resolv.conf instead of your ISP's name servers and that tries to sort out wrong (malicious) DNS answers; axfrdns, a service that runs on the master DNS server and to which the slaves connect for zone transfers; and tinydns, the actual DNS server, a very secure replacement for BIND.

Swift is a fully OOP Library for sending e-mails from PHP websites and applications. It does not rely on PHP's native mail() function which is known for using high server resources when sending multiple emails. Instead, Swift communicates directly with an SMTP server or a MTA binary to send mail quickly and efficiently. Swift is comparable to PHPMailer except that it implements an extremely flexible and innovative plugin system meaning you can get the most out of sending emails from your PHP applications. The interface for Swift is both tighter and more intuitive.
