The talk presents the status, concepts and techniques of the Debian-LAN project. It shows how Debian-LAN is capable of deploying a complete Debian based network out of the box including kerberized services, central user management, diskless clients and roaming machines. The deployment of a whole system environment in a local area network is an involved task. The Debian Local Area Network Project aims for making it as easy as possible without loosing flexibility. The Debian-LAN project uses FAI (Fully Automatic Installation) to deploy the system. It provides instructions and a FAI config space to install the following machines: A server providing DNS and DHCP, a Kerberos KDC, LDAP, GOsa for user management, ICINGA and Munin system monitoring, home directories via NFSv4, disk quota, squid proxy, apt-cacher-ng, a local APT repository, etckeeper and system backups. The workstations offer Xfce, LXDE, Gnome desktop enviroments and a customized package selection. In addition, diskless and roaming workstations (allow off-line use) are available. After the mainserver has been set up (from CD or by conversion of a minimal Debian installation) in a few steps, the other machines are deployed by just booting via PXE.
