Sorry for the confusion. Let me explain in more detail...
All Erlang nodes (a node is a complete Erlang system running on
some platform) can communicate in a transparent manner. For example on
an NT machine you could send a arbitrary Erlang message to any other
machine (solaris, freeBSD etc).
A couple of weeks before the OSE release we discovered a security
hole in the system and changed the implementation to deal with this.
We got as far as making the changes for the unix systems, but NOT
for the WIN32 systems. So all the unix systems CAN talk transparently
to each other but they will not be able to talk to the WIN32 system.
The Win32 build is more painful than the unix build so we
distributed the unix source + makefiles (with the new security fixed
protocol) and the win32 binaries (with the old protocol). These two
systems cannot talk to each other.
Last week tony () successfully built the
win32 system so that it can talk to the unix systems... We will put
this on the web site ASAP. Mail tony for more info.
