  • 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.

  • Introduzione a GlusterFS: uno storage scalabile e distribuito – Mia mamma usa Linux! – GlusterFS è un file system open source distribuito e scalabile orizzontalmente, la cui capacità può essere dinamicamente espansa mediante l’aggiunta di nuovi nodi. GlusterFS è in grado di arrivare a gestire fino a diversi peta byte, migliaia di client e diverse aree dati (storage) organizzandole in blocchi che rende accessibili su Infiniband RDMA (remote direct memory access, fibra ottica) o connessioni TCP/IP.
    Le risorse “memoria e disco” vengono rese disponibili sotto un unico punto di condivisione e tali risorse possono essere montate dai client mediante tre diversi protocolli: CIFS, NFS od il client nativo Gluster.
    Questo articolo effettua una prova su strada di GlusterFS, introducendone i concetti e sperimentandone le funzionalità.
  • 800 Open Source Packages for AIX Ready for Downloading NOW (AIXpert Blog) – [...] Instead of getting annoyed and complaining (like me), Michael decided to go and fix this short fall himself and a personal project and "give back" to AIX users world wide. So he compiles the open source packages on AIX and makes them freely available for download from:   http://perzl.org
       This website covers the AIX pre-compiled binaries for 800+ open source packages as RPM's and the other his hot project Ganglia for POWER, AIX and Power Linux [...]
  • Variable Expansion | Variables and Parameters in the Korn Shell | InformIT – Variable expansion is the term used for the ability to access and manipulate values of variables and parameters. Basic expansion is done by preceding the variable or parameter name with the $ character. This provides access to the value.

  • pWare – AIX Open Source software for IBM AIX 5.3 and 6.1 – AIX Open Source software for IBM System p server (formerly pSeries and RS/6000) machines running AIX 5.3 and higher. My name is Bill Jojo and I work at Hudson Valley Community College where we use a significant amount of Open Source software to manage our environment.
  • Create AIX NIM master – NIM is better in that you can install a new OS from a mksysb in as little as 5 minutes versus installing from CD which can take 40 minutes or longer. You can also keep your builds consistent if you have one mksysb image to build an AIX server. This also makes server builds easier at remote locations, no more swapping CD’s[...]
  • AixErrorLogCustomization < AIS < TWiki – AIX has a very flexible error logging daemon to log hardware and software errors. The log is typically accessed with the errpt command.
    Unfortunately, checking the log is a manual process. Using some custom ODM entries, we can cause AIX to run commands in response to errors, which can then be used for notification.
    Below I document a simple configuration which uses the ODM to log each error entry to syslog, and forward the complete entry via email.
  • c99madshell Security Review – Derek Fountain – A friend of mine got hacked recently. Some charming person managed to upload a rogue file to his server and replaced some of the software executables he produces with versions containing trojans and viruses.

    It seems there's not a lot of information available that describes just what is possible from an uploaded file vulnerability. So I grabbed a copy of 'c99madshell', which is one of the more popular scripts used by script kiddies, and had a look at what it can do. Here's what I found…
