Newbie:DBus message bus on multiple host?

[soulskylove]

Hello guys.I'm just a newbie in dbus.
Is there any step-by-step documentaion for message bus on different hosts?
 
 
session.conf on the host running dbus-daemon
<listen>tcp:host=0,0,0,0,port=6681</listen>
<auth>ANONYMOUS</auth>
 
then I restarted dbus-daemon ,ran dbus-launch tested the exapmle in the same host,It's ok.
 
Next, on another host, I set the DBUS_SESSION_BUS_ADDRESS=tcp:host
=192.168.0.1(ip of host),port=6681,then I ran the example.It says:Did not receive a reply. Possible causes include:...
 
Is there any thing I missing? Thank you very much.
