Diskless client installation

In the RHEL documentation (Chapter 4. "Diskless Environments", item #4) there is an in-accuracy in the rsync syntax usage.

JPPF offers an alternative, enabling a true heterogeneous nature of the Grid components, an ease of use that permits ...

OpenVPN my first trial

This note describes establishing VPN connection between my laptop and my remote Linux server. I was inspired by the first example in " Casting Your Net with OpenVPN " by Paul Duncan article that was published in the Linux Magazine.
