My first Opensource Server

I start learning Opensource seriously around year 2004 . During that time , i need to maintain 2 Freebsd server (Version 4.7) which used for external DNS . It was so pain since I'm a Windows lover that fall in love with 'mouse' .. Always need mouse and GUI to meet my server .
Unfortunately , the Freebsd server does not come with gui . I try to install Xwindows . But i'm too far to do that . Finally i decide to learn just DNS part . I start using easy editor to edit file . Since everything is in terminal , I lost all the GUI beauty and start digging in pain the DNS configuration from the server . From time to time I start to understand about named, dns table , and most importand is basic how DNS work in internet .
When my Office publish a new public server , i need to update the dns table . during that time , i thought i need to restart machine everytime i change the table .. hehehe . Finally i know i just need to restart named service ..
We have 2 dns server and act as Master slave . So i just need to update to master only . That's only my experience using Opensource about a year ...
