XMX is an X protocol multiplexor. It is a standalone utility for displaying
|
||
|
|
an X Windows session on multiple displays. XMX takes advantage of the
|
||
|
|
networked nature of the X Window System by tapping the communication link
|
||
|
|
between an X client and an X server. In this way, XMX works with any
|
||
|
|
X clients and any X servers, without the need to modify either.
|
||
|
|
|
||
|
|
It's tempting to call this "broadcast software," and that is certainly the
|
||
|
|
effect. In reality, though, XMX is "multicast" software. It must know
|
||
|
|
all the slave machines ahead of time and it connects to each one directly.
|
||
|
|
XMX is more like mail than news.
|
||
|
|
|
||
|
|
XMX connects to N servers like an X client, then accepts connections from
|
||
|
|
M clients like an X server. One of those servers is designated the "master"
|
||
|
|
from which input is directed to the clients. The other servers are "slaves."
|
||
|
|
Slave servers receive only those protocol requests that are necessary for
|
||
|
|
them to maintain a visual look-alike of the master server's display.

This software was developed at Brown University for use in our electronic
|
||
|
|
classroom. Some version of it has been in use here since 1988.
