  • Puppet is system administration – Automated. – Puppet is a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.
    By saving you countless hours of frustration, monotony, and/or reinventing the wheel, Puppet can change your life. Here are some key points about Puppet:
    Puppet lets you perform normal administrative tasks (such as adding users, installing packages, and updating server configurations) on any number of systems, even if those systems are running completely different operating systems. Through the use of providers, Puppet takes a generic instruction from you (such as ensuring MySQL is installed) and performs the task the "right way" for each system.
    Whether you have a small, heterogeneous network of user workstations or a cluster of rack-mounted number-crunchers, Puppet can help reduce your overhead and get the everyday management of your network under control so you can concentrate on the real problems.

  • Performance Tuning with "nmon" – Use this WebWizard to start Performance Tuning your IBM pSeries running AIX. This WebWizard assues you are using a freely available and very useful tool called nmon – full detail on getting this are below. nmon – is strongly recommended as it provides all the AIX statistics constantly updated on a "dumb" screen.
  • IBM Performance Management for Power Systems : overview – Your IBM Power™ Systems model (including the IBM System i®, the IBM System p® and the new POWER6™ models) can be one of your company's most valued assets.

  • Tuning the AIX file caches – Wikistix – By default, AIX is tuned for a mixed workload, and will grow its VMM file cache up to 80% of physical RAM. While this may be great for an NFS server, SMTP relay or web server, it is very poor for running any application which does its own cache management. This includes most databases (Oracle, DB2, Sybase, PostgreSQL, MySQL using InnoDB tables, TSM) and some other software (eg. the Squid web cache).

    Common symptoms include high paging (high pgspin and pgspout in topas), high system CPU time, the lrud kernel thread using CPU, slow overall system throughput, slow backups and slow process startup.

    For most database systems, the ideal solution is to use raw logical volumes. If this is not acceptable, then direct I/O and concurrent I/O should be used. If for some reason this is not possible, then the last solution is to tune the AIX file caches to be less aggressive

  • Samba e Active Directory .:. PippoFante.it – Unire una macchina Linux (*BSD, Solaris, …) a un dominio (Active Directory) Windows talvolta è comodo, talvolta è utile, talvolta è necessario. Per ottenere questo risultato si usa Samba.
  • Squid e autenticazione su Active Directory .:. PippoFante.it – È giunto il momento di rifare il proxy aziendale – ovviamente Squid – e con l'occasione cambio il metodo di autenticazione appoggiandomi al dominio: una password in meno per gli utenti e controllo più centralizzato. Le condizioni al contorno sono sempre quelle: Debian come guest su VMware ESX così aumentiamo la percentuale di virtualizzazione con tutti i pro (ma anche i contro).

  • 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.
