Configuring your system - Remote display connections

Remote Desktop

Windows users will be familiar with remote desktop, which uses the RDP protocol. There are a number of linux clients that provide connectivity using RDP. Before you continue, you may want to ensure the rdesktop USE flag is set in your make.conf, or per-package as below.

The rdesktop package provides command-line functionality for RDP connections. There is a gtk based frontend for the redesktop package called grdesktop, which is what we will focus on here. 

$ sudo emerge -av grdesktop

Once the emerge has completed, you can start the gui and create an RDP connection using the Network -> Remotedesktop Client item in your menu.

Inbound Remote Desktop Connections

This is possible via a combination of tigerVNC and xrdp. First, make sure the server USE flag is configured for tigerVNC. 

$ sudo emerge -av xrdp

After the emerge, configure the tigerVNC server.

Configure VNC Server

You'll need to specify the user whose X environment should be virtualized, and the environment specifics. 

$ sudo nano /etc/conf.d/tigervnc

DISPLAYS="username:1"

# Specify any of vncserver(1) and Xvnc(1) options. See the respective man pages for more information.
VNC_OPTS="-depth 24 -geometry 1280x800"

You will also need to set a password for vnc. 

$ vncpasswd

When done, start the VNC server and add it to startup if desired. 

$ sudo /etc/init.d/tigervnc start
$ sudo rc-update add tigervnc default

Configure XRDP

This guide may be useful, but I found the following configurations necessary and sufficient. Note that the port is specified in the global section, and overridden in the user xrdp1 section: 

$ sudo nano /etc/xrdp/xrdp.ini

[globals]
bitmap_cache=yes
bitmap_compression=yes
port=<your port>
crypt_level=low
channel_code=1
max_bpp=24

...

[xrdp1]
#name=sesman-Xvnc
name=sesman
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
#port=5900
port=-1

Once you've saved your changes, start the xrdp server and add it to startup. 

$ sudo /etc/init.d/xrdp start
$ sudo rc-update add xrdp default

You may need to poke a hole in your firewalls, but you should now be able to connect to your server using a remote desktop client on the port specified above.
