  • /bin/bash based SSL/TLS tester: testssl.sh – testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. [ via quasi.dot: https://delicious.com/farmando ]
  • Policy NAT for L2L VPN • LearnIOS.com – I kind of missed the wood for the trees here. The static policy NAT is failing because you are trying to map a network 192.168.0.0 to a single IP address 172.20.n.1. However it's just occured, why are you doing policy NAT for the Internet. I tested in lab and if you do this
  • Encrypted Data Bags on Cloud on AWS – Many customers have asked us how they should handle shared secrets, passwords and other sensitive data in Chef and now we have a good solution. With the release of our stable-v4 stack, we introduced Chef 10 to the platform, and with it came data bags. Now with the 3.0 release of the engineyard gem, we can officially support data bags and encrypted data bags. You may be wondering what data bags are, how data bags work or how to implement data bags. This blog post will walk you through the entire process.
  • How to set disk alignment in Linux | Dirty Cache – As you might know, if disk partitions containing Oracle datafiles are not aligned with the underlying storage system, then some I/O’s can suffer from some overhead as they are effectively translated in two I/O’s. If you want more info, google for “EMC disk alignment” and you’ll find plenty of information, explaining the issue.
  • Add Private Route 53 DNS to your AWS VPC | CloudTrek – A really cool feature of Amazon’s Route 53 DNS Management Service is the private hosted DNS zone.  Basically, you get the ability to manage the DNS in your private VPC without setting up your own DNS infrastructure (yuck!) [ Just a friendly reminder Note 1: the resolution is working only inside the VPC. Note 2: if you don't have the AmazonProvidedDNS in your DHCP-OPTION you won't resolve the zone. Note 3: if you are using linux, you can use as DNS 169.254.169.253 it won't work on windows 2008 Ref: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_DHCP_Options.html http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/hosted-zones-private.html http://aws.amazon.com/route53/faqs/ ]

  • 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.

  • Nuova “vecchia” vita per il Samsung NC10 | Gioxx’s Wall – Il mio vecchio Samsung NC 10 mi ha servito egregiamente negli anni passati e dopo un upgrade di RAM ed una prossima sostituzione disco può ancora rivelarsi un fidato compagno di lavoro per chi non necessita di prestazioni particolarmente elevate. Ad Ilaria basta ad esempio navigare in internet (Firefox), gestire la posta elettronica (Thunderbird) e utilizzare la suite Office di Microsoft, che funziona ancora perfettamente in coppia con l’anziano sempreverde Windows XP, si, proprio lui!

    Ecco quindi cosa fare con una chiave USB da 512 MB o più (ne avete ancora una in giro, ne sono quasi certo, nascosta da qualche parte) che verrà utilizzata una prima volta per installare il sistema ed una seconda per effettuare un backup completo del disco pronto.

  • Changing Windows RDP port | MWalker | Technology Cadre – Sometimes it's nice to change the default listening port of the Remote Desktop Protocol (RDP) service. Running standard services on non-standard is a simple way to avoid scripted attacks against your systems. Turns out changing the RDP port is as simple as a registry setting and a reboot.
  • Portable-VirtualBox | Download of Portable-VirtualBox – Portable-VirtualBox is a free and open source software tool that lets you run any operating system from a usb stick without separate installation.

  • Graphvis visualisation of Nagios Config – Nagios Exchange – Graphvis visualisation of complex Nagios configs.
    I have written a couple of utilities one to walk a nagios config tree and turn it into a perl hash (called nagparse)and another to use that hash converting the tree into a graphvis directed graph (called graphit). These are then brought together with a CGI program called explorenagios that lets you select what parts of the config to graph. If you have a non trivial config then showing it ALL in one graph is not fun!

    You can use the two component programs on the command line too – and feed the output into dot (it has been optomised to make nice dot graphs) or one of the other engines like neato if you want to do some hacking of the output options.

    It is now useful enough to be worth sharing. Not prefect yet but useful. Surprisingly fast.

  • Nagrestconf README – What is Nagrestconf?
    Nagrestconf is a REST interface and configuration GUI for Nagios.
    Nagrestconf is written in Bash and PHP.
    Specifically, Nagrestconf:
    allows Nagios configuration files to be written using a REST api.
    allows the server to be restarted using the REST api.
    provides a configuration Web GUI built on the REST api.
    It can be useful for:
    Bulk loading
    Bulk editing
    Automation
    Catching common configuration mistakes
    Configuration Delegation (using additional tools)
    Distributed monitoring (using additional tools)
    Not all of the Nagios directives are implemented, refer to the Status section.
  • Oracle Linux: A better alternative to CentOS – We firmly believe that Oracle Linux is the best Linux distribution on the market today. It's reliable, it's affordable, it's 100% compatible with your existing applications, and it gives you access to some of the most cutting-edge innovations in Linux like Ksplice and dtrace.

    But if you're here, you're a CentOS user. Which means that you don't pay for a distribution at all, for at least some of your systems. So even if we made the best paid distribution in the world (and we think we do), we can't actually get it to you… or can we?

    We're putting Oracle Linux in your hands by doing two things:

    We've made the Oracle Linux software available free of charge
    We've created a simple script to switch your CentOS systems to Oracle Linux
    We think you'll like what you find, and we'd love for you to give it a try.

  • configure time service on AIX host – Waldemar Mark Duszyk – First, you have to decide/select the appropriate devices to be your time providers. It could be one or more “official/public” time servers or maybe your routers. When you decide what these servers are you should validate that they deliver what you need and that you are (your host) is capable to receive and use what is delivered.

  • Plan your Exchange 2007 Backups based on Server Roles – When Microsoft created Exchange Server 2007, one of the biggest changes that they made was the creation of server roles. The concept of roles existed in Exchange server 2003, it was very limited. In Exchange server 2007, there are five different roles which serve five very specific purposes.

    Because these roles are so different from one another, the tasks that an Exchange Server performs, and the code that is installed is entirely dictated by the role that the server is configured to perform. That being the case, it is necessary to completely reevaluate your backup strategy.

  • Oracle LSNRCTL – Listener Shutdown and Startup Procedures – Starting up and shutting down the oracle listener is a routine task for a database administrator. However a Linux system administrator or programmer may end-up doing some basic DBA operations on development database. It is critical for non-DBAs to understand the basic database admin activities.

    In this article, let us review how to start, stop, check status of an oracle listener using Oracle listener control utility LSNRCTL.
