  • Checking UCS Settings from the UCS Manager CLI – I was recently using the UCS Manager CLI and I wanted to share my findings. You can SSH to the UCSM (UCS Manager) and then run commands to figure out information about your hardware configuration. Whenever working with Cisco UCS Servers, the first thing we need to figure out is how Service Profiles are used in a UCS Environment.
  • Add a VLAN to a UCS blade via the CLI | VirtuallyMikeBrown – What I really wanted to do was add a couple existing VLANs to the vNIC of an ESXi host on a blade (so I could vMotion some stuff around). Of course, with the GUI, it’s a few clicks. Without the GUI (and not knowing where to go in the CLI), I was at a bit of a loss.The UCS CLI guide wasn’t helpful as it was more for managing the hardware or upstream configs – not so much for what would seem like a task made for UCSM. So to get on with it, let me share the quick config for adding VLANs to vNICs.

  • Zsoldier’s Tech Blog: Add Portgroups/VLANs to vmware standard switches via PowerCLI – Wrote a simple little script to insert a portgroup into a targeted vSwitch of all VM hosts in a targeted cluster. This is not an issue if you use distributed vSwitches.

  • Hardening Framework – […] Server hardening is a well-known topic with many guides out in the wild. Why this project? At Deutsche Telekom we need to manage thousands of servers for customers and ourselves. All servers need to be configured properly and maintained, which is difficult and time-consuming to get right. To answer these needs for security, compliance, and maintainability, we decided to launch this project as a common ground for requirements and their fulfillment.[…]

  • High availability clustering on AWS | Zoran’s Blog – How do we keep legacy applications highly available on AWS? I have already written about this previously and there are many good alternatives with the upcoming Cloudwatch instance recovery the easiest to implement. Yet Cloudwatch instance recovery or autoscaling group with min=1,max=1 still requires failure to be detected (1-2 mins) and new instance to be booted up (2-3 mins). If the application can not tolerate outage of 3-5 minutes then high availability clustering may be a good alternative
  • jordansissel/pleaserun: An attempt to abstract this “init” script madness. – Pleaserun is a tool to generate startup scripts for the wasteland of sorrow that is process launchers.

  • JavaScript: The World’s Most Misunderstood Programming Language – JavaScript, aka Mocha, aka LiveScript, aka JScript, aka ECMAScript, is one of the world's most popular programming languages. Virtually every personal computer in the world has at least one JavaScript interpreter installed on it and in active use. JavaScript's popularity is due entirely to its role as the scripting language of the WWW. Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. How can this be a secret? Why is this language so misunderstood?
  • Dynamic multi-point VPN with OpenNHRP powered linux hub – This post aims to explain how to configure a dynamic multi-point site-to-site VPN over IPSEC between CISCO routers and a Linux machine using the NHRP protocol. […] To support the NHRP protocol I used OpenNHRP, an open-source implementation of the NHRP protocol. To bring up the IPSec tunnels, I used racoon with pre-shared key based authentication.

  • 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.

  • ipfs/ipfs · GitHub – IPFS (the InterPlanetary File System) is a new hypermedia distribution protocol, addressed by content and identities. IPFS enables the creation of completely distributed applications. It aims to make the web faster, safer, and more open. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. In some ways, this is similar to the original aims of the Web, but IPFS is actually more similar to a single bittorrent swarm exchanging git objects. You can read more about its origins in the paper IPFS – Content Addressed, Versioned, P2P File System. IPFS is becoming a new major subsystem of the internet. If built right, it could complement or replace HTTP. It could complement or replace even more. It sounds crazy. It is crazy. [ via http://blog.quintarelli.it/2015/12/ipfs-davvero-figo.html ]

  • Come suddividere il log di WordPress in file separati tramite Apache – Otherplus Tech – Quando usiamo WordPress su un server Apache siamo quasi sempre abituati ad avere un solo file di log per gli accessi del nostro sito e alcune volte due file per dividere gli accessi normali da quelli in errore. Ultimamente ho avuto un’esperienza da un cliente proprio su questo argomento specifico e abbiamo dovuto generare i file in maniera tale da dividere le informazioni che riguardavano la sezione classica da quella admin, ajax, wp-content etc.

  • Tiny Puppet – Yet Another Puppet Abstraction Layer – Tiny Puppet is a Puppet module that allows management of virtually any application on any Operating System: It’s based on the assumption that its user knows and wants to control how to shape the managed application’s configuration file: It’s not a joke, it just works like that, as long as our application can be installed via a native package (Tiny Puppet can manage also additional repos) and we know how to configure it.
