Autorenporträt

Carla Schroder is a self-taught Linux and Windows sysadmin, who laid hands on her first computer around her 37th birthday. Her first PC was a Macintosh LC II. Next came an IBM-clone, a 386sx running MS-DOS 5 and Windows 3.1, with a 14" color display, which was adequate for many pleasant hours of DOOM play. Then around 1997 she discovered Red Hat 5.0, and had a whole new world to explore.Somewhere along the way she found herself doing freelance consulting for small businesses and home users, supporting both Linux and Windows users, and integrating Linux and Windows on the LAN; primarily Linux servers and Windows clients. She is the author of the Linux Cookbook for O'Reilly, and writes Linux howtos for several computer publications.Carla is living proof that you're never too old to try something new, computers are a heck of a lot of fun, and anyone can learn to do anything.

Rezensionen

"Dieses Buch richtet sich an alle Administratoren, die schnell und ohne großen Zeitaufwand Lösungen für ihre Probleme suchen. Sehr abwechslungsreich geschrieben, sind hier für verschiedene Fachgebiete interessante Rezepte zu finden. Neben allgegenwärtigen Netzwerkthemen wie SSH, Routing, Firewall-Konfigurationen und VPN, findet man unter anderem auch die Einrichtung und Konfiguration eines Asterisk-Servers. Kurzum, das Buch ist ein echter Geheimtipp und sollte in der Sammlung eines Administrators nicht fehlen." - Linux UG Saalfeld/Rudolstadt, Februar 2009 "[...] Die Anleitungen sind [...] sehr schlüssig und es wird deutlich, dass sich Schroder sehr gut mit Linux-Networking auskennt. Hilfreiche Webseiten sind ausnahmslos genannt, an wichtigen Stellen geht die Autorin ins Detail. Fazit: Informativ und interessant, mit guten Projekten. Es gibt viel über Linux-Networking zu lernen, wenn man sich durch die Projekte arbeitet." - it-administrator, Juli 2008
