Woody Maniac – DNS Server (English Version 2)

We’ll cover setting up a LAN DNS server for a small LAN where the workstation addresses are statically assigned. If you have a larger LAN that uses DHCP, you’ll need to set up the server to respond to DDNS update requests because a system’s A record will need to be updated when DHCP assigns the system a different address.

In setting up a LAN DNS server we need to:

• Create the forward and reverse zone files.
• Update the named.conf configuration file with things called “forwarders”
• Update the named.conf configuration file so that the server knows it’s authoritative for the LAN domain.

DAS – Debian “Woody” Client Configuration (English Version)

The latest stable release of Debian GNU/Linux, 3.0r2 “Woody”, can easily be setup as a DAS client. All of the required packages can be installed with the built-in Advanced Package Tool, or APT. Updated Kerberos, PAM, and NIS packages are available. Configuration is fairly simple. Debian also supports the Name Service Cache Daemon, or NSCD. NSCD reduces the load on the NIS servers and the network by caching lookups for a period of time. It also helps with performance when the DAS-M (master) is unavailable.
