CVS is Deprecated for FreeBSD Ports

Please update your csup.conf remove ports from cvs/cvsup, new tools is portsnap (i dunno it will eat more bandwidth or not). Here is the announcement:


As announced in September the ports tree will no longer be exported to
CVS after February 28th 2013. All users who still use CVS, CVSup or csup
to update the ports tree are encouraged to switch to portsnap(8) or for
users which need more control over their ports collection to use
Subversion directly [1].

A migration guide from CVSup/csup to portsnap is also available in the
FreeBSD handbook [2].

More information regarding the end of ports CVS can be found in the
initial announcement [3].

My First TIme Using MacBook

How to replace Hostname/ComputerName ?

Apropos hostname didn't show any thing about how to replace hostname. Then try other command, i'm usually using man when seeking manual on BSD Unix & Linux, and from man  i got other command  scutil(8)., aha a new command. What is scutil?  From manual page give me information about scutil (Manage system configuration parameters). 

Now how to replace ComputerName & Hostname? :

$sudo scutil --set ComputerName Monyet
$sudo scutil --set LocalHostName Monyet
$sudo scutil --set HostName Monyet
