xmx - an X protocol multiplexor
SYNOPSIS
xmx [:displaynum] [-option ...] [display ...]
DESCRIPTION
Xmx is an X protocol multiplexor. It connects to some number of X
servers as a client, then accepts connections, as an X server itself,
from some number of X clients. It passes packets unaltered between the
clients and one controlling server. As it is doing this, it filters
and modifies the requests and passes them along to some number of slave
servers.
The effect is of an X session controlled by one server broadcast to the
other servers. The windows controlled by xmx on the slave servers do
not accept input, they are a visual echo of the controlling process.
OPTIONS
:displaynum
Specifies the display number for which to be an X server. This
number need not correspond to a real display - in fact it must
not if a real X server is running on the same machine.
-display display
Specifies the name of the master X server to connect to. If
this option is not specified, the value of the environment
variable DISPLAY is used. If DISPLAY is not set, the first
slave server listed becomes the master.
-f filename
Specifies a file which contains a whitespace-separated list of
display names to use as slave servers.
-p Echo pointer motion of master server to slaves.
-i Run in interactive mode. Commands are read from stdin.
-S Run in slave only mode. No controlling X server display is
opened. This option should only be used to run an xmx process
whose only client will be another xmx process. No interaction
is possible unless the topmost xmx has a master X server con‐
nection. This option is used to fan-out multiplexing to
increase speed or overcome system resource limits when broad‐
casting to a large number of displays.
-maxfd Set NOFILE to the maximum possible value. On systems that per‐
mit it, the number of active file descriptors is raised to the
system maximum.
-msb num
Increase the size of the outgoing slave socket buffers (SNDBUF)
by a factor of num. Can improve performance dramatically for
protocol intensive applications (clients that putimage large
images will benefit, for instance). However, making the buf‐
fers very large can wedge xmx's host machine. Setting num
larger than 4 is not advised.
-help Print a helpful message describing usage and options.
display...
The list of slave server displays can also be specified on the
command line. If the -f option is also specified, the lists
are merged.
SEE ALSOrx(LOCAL), X(1), Xserver(1)BUGS
Pointer motion could be improved. Interactive mode is currently a
hack. Does not support any extensions yet.
