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.
urlwatch – a tool for monitoring webpages for updates (thp.io) – This script is intended to help you watch URLs and get notified (via email or in your terminal) of any changes. The change notification will include the URL that has changed and a unified diff of what has changed. The script supports the use of a filtering hook function to strip trivially-varying elements of a webpage.

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.

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.
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:
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.
