freenx (Free implementation of the NX Server)
Freenx is an application/thin-client server based on nx technology.
NoMachine nx is the next-generation X compression and roundtrip suppression
scheme. It can operate remote X11 sessions over 56k modem dialup links or
anything better. This package contains a free (GPL) implementation of the
nxserver component.
Because a nx user with some default settings is needed for the server to
build, a script, preinstall.sh, is provided to be executed (sh preinstall.sh)
before running the slackbuild: it's pretty straightforward in his functions,
have a look at it. Also, after installation, you will need to run (as root)
"nxsetup --install" to complete the setup process.
This requires nx.
