This document outlines a project to simulate a centralized data center architecture by configuring operating system components like DNS, DHCP, and LDAP on Linux servers. The objectives are to set up DNS and DHCP servers, an LDAP server, and an Oracle database on three Linux servers connected by a switch. The current status shows the Linux clients connected to one Linux server running LDAP, DHCP and DNS. The document describes configuring each component and the significance of learning about technology infrastructure and tasks in a corporate environment.

15. Configure DNSDomain Name Server Identifying DNS servers Creating DNS Configuration files (named.conf file and the named directory) Starting the named daemon Monitoring named activities 11/20/2008 Minor Project Presentation 13

16. Configuration file (/var/named/chroot/etc/named.conf) - The main DNS server configuration file. Zone directory(/var/named/chroot/var/named) - The directory containing files that keep information about Internet root DNS servers (named.ca file) and information about the zones that are created for DNS server. Daemon process (/usr/sbin/named) - The daemon process that listens for DNS requests and responds with information that the named.conf file presents. Debugging tools (named-checkconf, and named-checkzone) - used to determine whether DNS Configuration is correct. 11/20/2008 Minor Project Presentation 14
