  • Simplify Advanced Shell Scripting With Ruby | AIX | IBM Systems Magazine | System p, System p5, Power System | Ruby, SSH, shell scripting, Bull Freeware, sysadmin, – IBM Systems Magazine – Ruby is just for experienced programmers. right? False! Originating in the mid-1990s, Ruby is a fantastic language, made popular recently by the Web application framework—Ruby on Rails. It’s a massively flexible and easy language to learn. You can find Ruby for AIX in the AIX Toolbox at the Bull Freeware. The script we’ll be creating will do the following:

     

    * Go through a large list of servers.
    * SSH them and determine whether the server is AIX.
    * If so, it will go through all disks, returning their type.
    * It will do all of this completely in parallel in batch at 25 sub-processes at a time.

  • Recovering a lost partition table with a VMFS volume | vInfrastructure Blog – Vi possono essere diversi motivi che portano alla perdita della tabella delle partizioni o alla sua corruzione. Nel caso di datastore VMFS le possibili cause sono: resignature da un altro sistema (ad esempio il backup server, nel caso funzioni in SAN mode), un errore umano (basta eseguire, su dischi condivisi, da vSphere Client un Datastore / Delete da un ESXi non ancora collegato al vCenter Server), o anche a causa di qualche problema lato storage (mi è capitato proprio questo caso di recente su uno storage entry level)[…]

    (Mi è capitato, ho seguito la kb di vmware e ne sono uscito. Comunque sto sudando ancora adesso…)

  • 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.

  • Top 10 things you must read about vSphere 5.1 – Welcome to vSphere-land! – There has been so many documents, white papers, videos and blog posts posted about the vSphere 5.1 release that it’s hard to keep up with them all. I have at least 250 links gathered in my vSphere 5.1 Link-o-rama and it is still growing. With so many links it’s easy to miss some of the really good ones so I thought I would put together a top 10 list that highlights the ones that you don’t want to miss.
  • Three things you should never put in your database | Revolution Systems – As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things". I don't mean you or your development staff is "dumb", it's easy to overlook the implications of these types of decisions and not realize how bad they are for maintainability let alone scaling. As a consultant I see this stuff all of the time and I have yet to ever see it work out well for anyone.

  • 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.

  • Tony’s VMware Site – I have assembled a package which you can download which will allow you to have Sound, Network, and CD ROM in your Windows For Workgroups 3.11 Virtual Machine.  I also have found a copy of Netscape 4.0 which will work with Windows 3.11.
  • Michele’s blog » Temperature in your server room – At work we bought a couple of Ethernet Boxes from MessPC to keep an eye on our different server room and monitore temperature, humidity and the presence of smoke. These Ethernet boxes are quite neat: they have one network port (10 Mbps half/duplex only, beware) and four RJ-45 ports where you plug-in the sensors you need. We got sensors for temperature, humidity and a smoke alarm.
  • Nagios plugin debugging – This little perl-scripts captures STDOUT and STDERR of a nagios plugin. It writes the captured output to a temp. file. Then the output is returned to Nagios for further processing.

    This allows to track down some problems when using plugins within Nagios. You'll get some information if you have problems accessing files, can view the expanded command-line parameters of service checks, view the performance data returned in a text file, etc.

    It did help me several times – so feel free to try this out.

  • ESXi – Come resettare la password di root | vInfrastructure Blog – […] In VMware ESX 3.x resettare la password di root era banale, visto che era scritta in un filesystem Linux in una partizione facilmente modificabile da qualunque distribuzione live. Già con ESX 4.x è cose si erano fatte leggermente più complicate, visto che la service console non risiedeva più su una partizione fisica ma dentro un vmdk.

RVC can be installed on a Windows, Linux or Mac OSX system and it's built on RbVmomi which is an open source Ruby library/bindings to the vSphere API.

  • VMware Monitoring Appliance with Nagios, NagVis, PNP4Nagios, Smokeping, Cacti and OpenNMS – Monitoring in just a few minutes! This VMware appliance based on Ubuntu Server Edition 10.10 64-bit contains the most important monitoring software packages, installed and ready-to-run:

    Nagios 3.2.3
    NagVis 1.5.5
    PNP4Nagios 0.6.7
    MK Livestatus 1.1.8
    Cacti/Spine 0.8.7g
    Smokeping 2.3.6
    OpenNMS 1.8.5

    You can start immediately. It is especially suitable for comparing these different monitoring solutions. Note that OpenNMS is written in Java and produces a high load on the system. Starting and Stopping OpenNMS takes a long time (several minutes!).

  • Squid Block – DNSBL Redirector for the Squid Proxy – dnsbl_redir is a shamelessly derived redirector based on the asqredir redirector written by Thomas Zippo < thomas at zippo dot ch >. Thanks!
    Its been rewritten to use a DNSBL list (RHS type) to check for and block sites listed in the DNSBL. It will redirect your users to the page/site listed in the top of the dnsbl_redir.h file.

    dnsbl_redir is written in C. It consists of one small source file and a small(er) .h file. It has been tested and runs on the current Squid versions. It performs very well on Linux (RedHat/Fedora), BSD and technically should compile and run on any gnu/linux.
