I looked into this some more, and found the cause of this problem - the sen=
ding
server isn't properly getting the UDP port to send to from it's own configu=
ration.
The work-around is to add the line=20

listen=3D6789

to the file /etc/webmin/servers/config on the sending system.

Ok, I see what is going on how - Webmin isn't handling a packet being
received twice from the same address in the same scan. This will be fixed
in the next release though.
