  • Tuxevaras Blog » AIX – NOTA BENE:Although the content of this guide is already five years old, I don’t want to remove it from the net. I suppose it should work also with a Windows 2008 Active Directory domain as well. But please do not ask me questions about AIX5L as I do not have access to any of those machines any more…

Furthermore we have an Offsite Replication Server, which ideally stands in a physically different position and replicates the configurations/storage from which ever node is active. In case of emergency this Offsite Replication Server can be used to restore the cluster and to deliver the services [...]
  • Using m4 with Nagios: Advanced Ideas – Nagios configuration has been traditionally cumbersome and extensive; there are a lot of things to configure. The addition of templating some time ago helped, but not entirely.

  • Random.org – RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive games and gambling sites, for scientific applications and for art and music. The service has existed since 1998 and was built and is being operated by Mads Haahr of the School of Computer Science and Statistics at Trinity College, Dublin in Ireland.<br />
