8. Linux x BSD
The main difference between Bind on FreeBSD and Bind on Linux is the path of the files or how to start the server on boot time, but major things are the same. Like the content of the configuration files.
===Gregory Katherine Masseau===
Differences in DNS between freeBSD and Linux:
'''Differences'''
I think the most difference of DNS between Linux and BSD is the path. Linus's named path is /var/named/ when FreeBSD uses /var/named/etc/named/. And the start up binary files are also stored in /etc/sbin/named
There Actually, there are not much different of name server between linux and BSD. Since BIND is an open source package, and linux and BSD are using it. The way to configure name server are the same too. Althought Linux and BSD save config files in different location since they have different file structure.
