All the computers in our house are networked. The main server (tux) is based on Ubuntu Linux The services provided include NIS/yp, DNS, NFS, cups, dhcpd, Apache, Samba (for Windows workstations) PostgreSQL and MySQL for the Intranet. E-mail uses postfix/fetchmail. Time synchronisation is maintained by the use of ntp.
A recent addition is the Asterisk PBX to provide a VoIP telephone system.
The network supports IPv6 and is full routed via a tunnel/subnet from SixXS http://www.sixxs.net.
