IntroductionThis page describes how to configure the HP-UX LDAP client services to authenticate against OpenLDAP. For the OpenLDAP configuration see: LDAP server configuration RHEL 5.The OpenLDAP directory server must be prepared and configured in advance before the HP-UX LDAP clients can be configured and the HP-UX system will authenticate against the directory.

It has been a while since our last post. But two days ago we started work on an interesting, though perhaps a bit weird, challenge: to get xubuntu 8.04 Beta to work on an old Dell Latitude CPi. This is the trouble we get into when we boast about how great Linux is and that it is more than ready for the desktop ;-). We choose xubuntu because of it's claim to be light and easy on the hardware.We

Two weeks ago we had the opportunity to do some work for a customer in Brussels, Belgium and to use a Hewlett Packard blade system. The HP blade rack was stored in a separate computer room from the training room and we used full remote access to install Red Hat Enterprise Linux 4 from a USB key attached to a laptop running SuSE Linux. The USB key contained ISO images from the 4 RHEL 4

1. IntroductionRegularly during our classes, especially with a more 'advanced' audience, over the last few years we have had to explain in quite some detail the basics about installing Red Hat Enterprise Linux manually from the CDs (this link points to version 5 now, RHEL version 5 will be covered in the future). Happily nowadays the process is quite straightforward, as long as the underlying

At meetings with our customers and during the actual courses we teach we regularly need

Quite regularly during our Linux courses and other work we have had the need to quickly demonstrate X-Windows' ability to provide full graphical logins into a "central" Linux (e.g. Red Hat Fedora or RHEL) system. Every time we try to do this it is a struggle to remember how to do so, as the security of the central host prohibit us or some misunderstood behaviour of the XDMCP protocol plays up
