coderwall.com : establishing geek cred since 1305712800 – Setting up an EC2 instance on AWS used to be as straightforward as provisioning a machine and SSHing into it. However, this process has become a bit more complicated now that Amazon VPC has become the standard for managing machines in the cloud.
Set up public and private subnets using AWS VPC — Mike Melnicki’s Blog – This is a step-by-step guide on how to set up public and private subnets for running a service on an internal network within AWS. This guide will also set up a bastion host (or jump host) and show you how you can easily ssh in to the hosts within your private subnet via the bastion host. All of this stuff can be done via the AWS web console, but I thought it would be helpful to show the specific commands and provide some commentary about what is happening on each step.
WordPress Checklist (Infographic): 101 Easy Steps to Follow. – It’s a big struggle in remembering the steps involved in setting up a WordPress website. And we soon realized that, there were hardly any checklists that covered all the aspects of WordPress together! That’s when we decided to create “Killer WordPress Checklist” that would cover everything from the pre-launch directions and development process, to SEO, maintenance and security. Honestly, this checklist has worked wonders for us and hope it does for you too!
Monitoring EC2 Memory and Disk Usage In CloudWatch Using Custom Metrics | Celingest Blog – Feel the Cloud – With CloudWatch we can track and monitor a lot of metrics across many AWS’s products and set alarms when certain conditions are met. When these alarms are triggered, they can notify us or automate actions such as shrinking or increasing an AutoScaling Group capacity. CloudWatch knows a lot about our EC2 instances’ at the hardware level but it lacks the software’s point of view. In this post we will explain how to use CloudWatch to monitor important resources it can’t monitor by default.

SIAMO GEEK – Sperimentatori, entusiasti della tecnologia | Rigenerare le chiavi ssh – Quanto è vecchia la vostra chiave ssh? Rigenerare le chiavi ssh usate per collegarsi ai server è una rottura di scatole, ma potrebbe essere una rottura di molte unità di grandezza inferiore rispetto allo scoprire che una chiave ssh viene usata da mesi a nostra insaputa. Quanto sono corte/lunghe le chiavi ssh registrate nei file authorized-keys dei vostri server? Per fortuna a questa ultima domanda c’è una risposta veloce sotto forma di un pratico script shell.
Downloading Java RPM from wget | Giuseppe Paternò – This is a very basic post, but I consider it for myself rather for public consumption. I needed to download the Java RPM from the Oracle website from command line, as I’m connected to my systems from a low bandwidth site. I needed to find the cookies that Oracle website uses for “accepting” Oracle license to use properly wget from command line.

microHOWTO: Configure Apache to use Kerberos authentication – To configure Apache to use Kerberos authentication Kerberos is an authentication protocol that supports the concept of Single Sign-On (SSO). Having authenticated once at the start of a session, users can access network services throughout a Kerberos realm without authenticating again. For this to work it is necessary to use network protocols that are Kerberos-aware. In the case of HTTP, support for Kerberos is usually provided using the SPNEGO authentication mechanism (Simple and Protected GSS-API Negotiation). This is also known as ‘integrated authentication’ or ‘negotiate authentication’. Apache does not itself support SPNEGO, but support can be added by means of the mod_auth_kerb authentication module.

thomastk/kunjumon – Kunjumon is a framework that can be used to create plugins for Nagios monitoring system, without writing any new code. The plugins thus created are robust, and, can monitor complex scenarios by querying data from multiple databases. While efforts to build such plugins would require considerable scripting work, using Kunjumon framework, a a plugin that pulls input data from databases can be implemented by defining it in XML format, and, there is no need to write any code to support it. The Kunjumon framework has been tested on all the Linux platforms, and against MySQL, Postgres, Oracle and Microsoft SQL Server. However, in general, it would work with any ODBC interface configured on the Nagios host to access a data repository.

Sensu | The open source monitoring framework. – […] Sensu is often described as the “monitoring router”. Essentially, Sensu takes the results of “check” scripts run across many systems, and if certain conditions are met; passes their information to one or more “handlers”. Checks are used, for example, to determine if a service like Apache is up or down. Checks can also be used to collect data, such as MySQL query statistics or Rails application metrics. Handlers take actions, using result information, such as sending an email, messaging a chat room, or adding a data point to a graph. There are several types of handlers, but the most common and most powerful is “pipe”, a script that receives data via standard input. Check and handler scripts can be written in any language, and the community repository continues to grow! […]

DMX Homepage – Typical X servers provide multi-head support for multiple displays attached to the same machine. When Xinerama is in use, these multiple displays are presented to the user as a single unified screen. Xdmx is proxy X server that provides multi-head support for multiple displays attached to different machines (each of which is running a typical X server). When Xinerama is used with Xdmx, the multiple displays on multiple machines are presented to the user as a single unified screen. A simple application for Xdmx would be to provide multi-head support using two desktop machines, each of which has a single display device attached to it. A complex application for Xdmx would be to unify a 4 by 4 grid of 1280×1024 displays (each attached to one of 16 computers) into a unified 5120×4096 display. Xdmx was developed and run under Linux (ia32 and x86_64) and has been tested with SGI Irix.

Today's version of Hubot is open source, written in CoffeeScript on Node.js, and easily deployed on platforms like Heroku. More importantly, Hubot is a standardized way to share scripts between everyone's robots.
