Red Hat company has recently opened its Knownedge Base – great collection of answers to frequently asked questions about linux systems. You no longer need to login to access it.
Red Hat Knowledgebase is a library of tips, troubleshooting advice, and current information updated daily by Red Hat technicians.
As for me, it is great news, because RHKB is one of the best libraries with information about linux systems.
