- One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
- Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via http://onethingwell.org/post/134852940551/tsung ]
- Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

- AWS Performance Tuning – This guide introduces best practices for tuning Riak cluster performance in the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) environment.
- Guide to Windows Batch Scripting – /* steve jansen */ – This series will share some of the tips and tricks I’ve picked up through the years of working with Windows professionally. I’ll be the first to admit the Unix shells of the world are far superior to the Windows command prompt (or even Windows PowerShell). Windows is a fact of life for most professionals writing code for coporate customers; this series aims to make life with Windows a little easier.

- wg/wrk · GitHub – wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue. [ via http://onethingwell.org/post/56882294128/wrk ]
- Automate and manage systems installation with Cobbler – Cobbler simplifies system provisioning by centralizing the tasks that are involved in setting up and administering an installation server. This article discusses some of Cobbler's features, how to install it, and how to create a configuration suitable for automatically installing multiple client machines.
- Cobbler – Linux install and update server – Cobbler is a Linux installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux tasks so you do not have to hop between many various commands and applications when deploying new systems, and, in some cases, changing existing ones. Cobbler can help with provisioning, managing DNS and DHCP, package updates, power management, configuration management orchestration, and much more. (And you can integrate with chef or puppet)
- Redhat I/O Scheduler Configuration in a Virtual Machine. – FATMIN – […] However, because of the fact that ESX is its own built in elevator, the Linux kernel's elevator is not needed, and in fact can hurt disk performance. So its best to disable the elevator inside your linux VMs […] Da controllare comunque dovrebbe andare anche su altre distro
- RDP with NLA from Linux – Is there a way to connect to a Windows 2008 Remote Desktop Services with NLA from Linux? Yes! FreeRDP is a fork of Rdesktop. Rdesktop seems to have stopped developement, so a fork is very welcome. NLA is still not in the main release, but it isn't hard to check out a copy from GIT and compile the latest source yourself.

- AIX A-Z: Learning AIX’s spooler back-end programs – Summary: While most IBM® AIX® administrators know how to set up print queues and manage printing through the System Management Interface Tool (SMIT) or the general print commands, there's more to printing on the UNIX® system. If you want to learn more than just how to set up or manage virtual printers on AIX, this article is for you. Most successful AIX and UNIX administrators thrive on learning more about the system they administer. Printing is only one facet of their system, but it's an important one to know.
