Infos

Gerade für den Administrator kleinerer Netzwerke kann es interessant sein, sich über Open Source Tools zu informieren. Inzwischen gibt es schon einige Tools, die teilweise mit den Produkten kommerzieller Anbieter konkurrieren können.
Insbesondere für mittelständische Unternehmen, für die der Preis käuflicher Produkte zu hoch ist, kann das eine Alternative sein. (S. auch die Beschreibung meines Umstiegs von Windows auf Linux)
