Files in the /etc directory (what each of them do) 
In my machine, there are 79 files in the /etc directory. 
  /etc/fstab       --contains file systems
  /etc/ftpusers    --list of users disallowed any ftp access
  /etc/group       --contains the group of the system
  /etc/hosts       --the hostname and their IP address that can be recognized by the local machine
  /etc/inetd.conf  --internet server configuration database
  /etc/netconfig   --the network configuration file
  /etc/netstart    --start network for user convenience
  /etc/passwd      --contains the users of the system
  /etc/rc          --start-up script
  /etc/rc.conf     --the configuration file of start-up script
  ... ...
Setting up a network 
In the file /etc/rc.conf, we can configure the network card.
Start-up scripts in FreeBSD 
In FreeBSD, the start-up scripts is in the /etc/rc.d directory. If you want to make them enable, you should set them in the /etc/rc.conf file.
