dxpc for Debian
---------------
Notes from Joe Reinhardt <jmr@debian.org> Sat Dec 16 22:27:43 CST 2000:
dxpc is an X protocol compressor designed to improve the speed of X11
applications run over low-bandwidth links (such as dialup
connections).
To be useful, you need to have a compiled dxpc running in "Client
Proxy" mode on another computer. If the other computer is a
non-debian machine, you may need to obtain the dxpc archive and
compile it yourself on the non-debian computer. Precompiled binaries
for many systems are available from http://www.vigor.nu/dxpc/.
The executable in this package can run as either a client or a server.
For more information, see http://www.vigor.nu/dxpc/.
Additional notes:
dxpc is a very useful tool, but it can be complex to figure out the
setup from the documentation. For applications in which both machines
can access each other's IP addresses, the examples in the manual page
should be sufficient. Here's a simple recipe for using it from a host
behind a firewall to access another host, tunneling dxpc through ssh.
This assumes you are sitting in front of 'local' and are logging into
'remote' with ssh.
# Get the xauth key for your current local display for later use
local% xauth list localhost.localdomain/unix:0 | awk '{print $NF}'
# Map local port 4000 to remote-host's port 4000
local% ssh remote -x -L 4000:localhost:4000
# On the remote host:
remote% dxpc -f
remote% xauth add localhost.localdomain/unix:8 <key-from-above>
remote% export DISPLAY=:8
# In another window on the local host:
local% dxpc -f localhost
Now you are ready to run X applications on 'remote' displaying on
local with reasonable performance even on a slow link.
