NetBSD RDP/VNC survey

This page aims to provide a complete list of VNC/RDP implementations which can likely be ported to NetBSD. As a further goal, documentation will be added on how to install and configure the particular implementations.

Client implementations

Name License Protocol pkgsrc Linux FreeBSD port
Remmina ? VNC, RDP, NX3, XDMCP ? ? ?
EchoVNC GPL VNC, RDP, RAdmin1 no yes1 no
KRDC GPL RDP, VNC no yes no
RealVNC GPL VNC yes yes no
TightVNC GPL VNC yes ? ?
rdesktop GPL RDP 5 yes yes yes
FreeRDP2 GPL RDP 5 no yes yes

Server Implementations

Name License Protocol pkgsrc Linux FreeBSD port
x11vnc GPLv2 VNC yes yes yes
xrdp GPL RDP wip yes yes
FreeNX3 GPLv2 NX no yes yes

1 Unreliable source (i.e. only Wikipedia).

2 FreeRDP is a fork of rdesktop.

3 NX protocol may be ignored completely since there's not going to be available open-source implementation any time soon.

  1. Bring other RDP and VNC software to pkgsrc.
  2. Check interoperability of servers and clients for NetBSD and other desktop systems (MS Windows, MacOS X).


  1. UltraVNC
  2. TigerVNC
  3. ITALC
  4. Check interoperability with stock MacOS X VNC server, it has extensions not handled by TightVNC and RealVNC at least. I have to run this to make it possible to connect to MacOS:
sudo /System/Library/CoreServices/RemoteManagement/ -verbose -activate -restart -agent -allowAccessFor -allUsers -privs -all -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw some-password

Setting password is essential here. Tested on Darwin 10.3.3 x86_64.


  1. Update xrdp in wip, bring xrdp to pkgsrc.


  1. Check trends in NX software (I heard free package isn't going to be supported anymore).


  1. Check pkgsrc/net/vinagre.
  2. KRDC
