untrusted
$ xauth -f ~/.Xauthority2 generate blue:2 . untrusted
You can then query a specific authority file to get the token:
$ xauth -f ~/.Xauthority1 list blue:2
These tokens can be transferred to different remote machines as needed.
Effective use of the X Security extension mildly improves the basic cookie scheme to
improve privacy, but the gains are minimal.
13.11 Low-Bandwidth X (LBX)
X provides a mechanism that is supposed to reduce bandwidth and latency requirements
for X applications and that is called LBX??”but it doesn??™t make any appreciable
difference for most applications. Nonetheless, it??™s interesting to know how it works
and why it??™s fallen into disuse.
LBX was part of the ill-fated Broadway remote-access initiative, and it consists of two
parts:
LBXproxy
A proxy server that runs on the client host. X clients connect to LBXproxy
instead of the X server; LBXproxy then communicates with the server, using
compression and caching in an attempt to reduce traffic.
The LBX Extension
If data is being compressed on one end of the connection, it must be decompressed
at the other end. The LBX extension to the X server provides the other
end of the link.
Before attempting to use LBX, confirm that your server supports it.
