So I get stranger troble is disconnecting each computer together. This happened with random time, maybe about 15 minutes after running as well. In /var/log/message I got movement ARP entry to other MAC ADDR on the same IP ADDR. Everyone know what happen is? Is that ARP Poisoning. If the answer yes, how to preventing or resoloving this problem? Thanks You For Advance. -- budsz
