Steve,

the output is:
Server: 192.168.18.10
Address: 192.168.18.10#53

Non-authoritative answer:
Name: datacenter5.papa
Address: 61.140.3.66

And none of them is the address of datacenter5(192.168.52.129). How can 
I solve this problem?
BTW, I can ssh to datacenter5(master) without password.

thx!
