Network File System (NFS) Server and Client Configuration in Debian

NFS was developed at a time when we weren’t able to share our drives like we are able to today - in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment.

Setting Up A DNS Server On Ubuntu Edgy With MyDNS And MyDNSConfig

In this tutorial I will describe how to install and configure MyDNS and MyDNSConfig. MyDNS is a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. The advantage is that MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted. A secondary nameserver can be easily set up by installing a second instance of MyDNS that accesses the same database or, to be more redundant, uses the MySQL master / slave replication features to replicate the data to the secondary nameserver. http://www.howtoforge.com/mydns_mydnsconfig_dnsmasp_on_ubuntu_edgy
