xrdp server setup used for first robotics / wpilib

README.md

xrdp and lxc

This is a half-done attempt at making a rdp server in lxc. It was largely based on ubuntu-xrdp. I'm not sure all of the things are necessary, but the result is a functional xrdp server.

I did this to see if it is feasible to host remote development system for students.

At least one annoyance is that on linux you cannot install "for all users", so each user would end up with ~2.6G of ~/wpilib. That also manifests itself in updating dev tools.

build container

from ubuntu-xrdp

$ lxc launch ubuntu-daily:focal rdp-build
$ lxc exec rdp-build /bin/bash
% apt-get update
% apt-get install --no-install-recommends build-essential
% apt-get build-dep pulseaudio
% apt-get source pulseaudio
% cd pulseaudio-13.99.1
% dpkg-buildpackage -rfakeroot -uc -b
% cd ..
% sudo apt-get install --no-install-recommends libpam0g-dev nasm
% git clone --branch devel --recursive https://github.com/neutrinolabs/xrdp.git
% ./bootstrap && ./configure && make && make install
% cd ..
% apt-get install --no-install-recommends install libpulse-dev 
% git clone --recursive https://github.com/neutrinolabs/pulseaudio-module-xrdp.git
% cd pulseaudio-module-xrdp
% ./bootstrap && ./configure PULSE_DIR=/root/pulseaudio-13.99.1
% make
% mkdir -p /tmp/so

build the runtime system
