  • Howto: Change the IP address of a Dell 4/P DRAC from the command line without rebooting the server – Normally you configure a Dell Remote Access Card (DRAC) when a server is initially commissioned. Once the card is set, administrators rarely if ever need to modify the settings. If you do need to change the settings, the server needs to be restarted so the DRAC BIOS can be modified, which obviously results in system downtime and requires a physical presence at the server console.
  • bash ini parser | /var/log/ajdiaz – In some situations i like to use INI files as configuration files, as python do. But bash do not provide a parser for these files, obviously you can use a awk code or a couple of sed calls, but if you are bash-priest and do not want to use nothing more, then you can try the following obscure code:
  • Jugg Monkey: VMWare HA Agent had an error – I recently had a problem with one hoste in a 3 node VMWare ESX 3. 5 cluster. For some reason, the HA Agent would not start after I applied outstanding software updates. I kept receiving "VMWare HA Agent had an error" in the alerts after the host came online. I had recently needed to change the IP address of the VMWare 3.5 ESX host, so I figured that was the root cause.

  • andihofmeister/squidGuard · GitHub – squidGuard cleanup/rewrite

    The version here is a rewrite of most of the code. While it provides (almost) all features found in SG 1.5, the configuration is not entirely compatible.
    This repostiroy does NOT contain an official version of squidGuard (see below)

  • eAccelerator – eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.
  • Server World – Build Network Server – This site explains how to build home server connected to internet with static IP address. You need to get at least one static IP address from your ISP. Please make sure the terms of use from your ISP, and Get one or some IP addresses if possibles. It's possible to build a network server, not with static IP address but with dynamic IP address by using Dynamic DNS, though. But I don't recommend it because there are some limits. It's the best to get at least one static IP address in order to build a network server, there is no limit. To get one static IP address is not so high costs. It's easy to build network server at your home.
    This site explains how to configure a server with commands basically, not with Graphical User Interfaces.

  • Optimizing WordPress with Nginx, Varnish, APC, W3 Total Cache, and Amazon S3 (With Benchmarks) | danielmiessler.com – So I’ve spent the last couple of weeks tweaking my web server stack. I like my site to pop, and I’ve finally achieved a configuration that I’m somewhat happy with.

    In sum, I’m running Varnish as a front-end to Nginx which is running WordPress loaded with the W3-Total-Cache plugin. The W3-Total-Cache plugin is configured to use both memcached as well as Amazon S3 as its CDN. All of this sits on Ubuntu Linux with Linode as my host.

  • A Varnish Primer | danielmiessler.com – Despite the title, this article has nothing to do with painting. Here I'm going to talk a bit about the Varnish Cache — a web application accelerator designed to dramatically improve how quickly your website loads. Varnish works by caching and serving as much content as possible as "static", including dynamic results, e.g. blog posts from a CMS like WordPress.
  • Varnish best practices « Kristian Lyngstol’s Blog – A while ago I wrote about common Varnish issues, and I think it’s time for an updated version. This time, I’ve decided to include a few somewhat uncommon issues that, if set, can be difficult to spot or track down. A sort of pitfall-avoidance, if you will. I’ll add a little summary with parameters and such at the end.
  • Cain Manor | Setup logging for Varnish – So far, we’ve got Var­nish installed and have a cor­rect default.vcl. Now let’s make sure AWStats/JAW­Stats can read them.

  • DNS e Postfix: come non generare "spam" | Kreations Collective – [...]Ho recentemente configurato alcuni server per l’invio di email. Parte del lavoro ha riguardato la corretta configurazione di Postfix e del server DNS per evitare che le email inviate venissero rilevate come spam.[...]<br />
    La configurazione ha riguardato tre punti principali:<br />
    Impostazione del record A e del reverse address<br />
    Impostazione di SPF<br />
    Configurazione di DKIM e DomainKeys<br />
    [...]
  • How to build your own CDN using BIND, GeoIP, Nginx, Varnish | UNIXy – In this article, we shall outline the steps required to build a private Content Delivery or Distribution Network (CDN) using a VPS with Varnish Cache and Nginx. The goal is to build a CDN using free, readily available software but most importantly spend the least amount of funds possible. To this end, all nodes participating in this network are going to be virtual machines (Xen, Virtuozzo, OpenVZ, etc). Should you have any questions or comments on the configuration of this CDN, please post them in this forum: http://www.varnish-cache.info/
  • Comandi testuali per i sistemi Windows – [...] Al lavoro, spesso mi capita di dover eseguire le stesse operazioni su più server, più volte alla settimana. La maggior parte di queste operazioni riguardano utilità di sistema di Windows, come la gestione utenti di Active Directory, o quella del DNS od altro ancora. Certo, un collegamento sul desktop è comodo, ma in talune situazioni può tornare decisamente comodo (e più veloce) conoscere il nome degli eseguibili relativi ad un determinato pannello MMC, piuttosto che l’apposita applicazione contenuta nel Pannello di Controllo.<br />
    <br />
    Quello che segue è un elenco della maggior parte di questi comandi, tutti lanciabili direttamente dal pannello “Esegui” situato nello Start Menu di Windows. Alcuni di questi comandi possono essere distruttivi, portando addirittura alla formattazione del disco ed alla conseguente perdita di dati, per cui usateli solo se ritenete di essere in grado di farlo [...]
