When I make ping to other machine from the server, the server will again restore and accept connection. This is weird, so my temporary solution is to let the server continually ping other machine. Please help. Thanks again. junji aisalen.wordpress.com Linux Registered User #253162 Send instant messages to your online friends http://uk.messenger.yahoo.com
