Like this ?

Add the following line in localdomain zone file :

"
server IN  A      127.0.0.1
aaa   IN CNAME  server "

then reload the named service .


But when I run this command "ping aaa" , it has no result .
And it print "Unkown host aaa" message.

By the way , aaa is not the domain name, it maybe the hostname alias.
