ok, i found something odd
i can't locate zimbra.asi.com when i do nslookup from slave server
Code:
[root@mail2 ~]# nslookup zimbra.asi.com
Server: 192.36.253.120
Address: 192.36.253.120#53
*** Can't find zimbra.asi.com: No answer
ok i think i found the root problem
my slave server cannot see the master server..
any ideas on how to resolve this?
