Everything should work. Cadence needs some fonts (too lazy to find out which exactly), so it's recommended to install these add-on packages from: https://www.nomachine.com/NX-3-5-0-Download-Package&Prod_Id=3835:

Finally, save the complete config into an nxs file (e.g., can be found in %USERPROFILE%\.nx\*.nxs) and create a shortcut. This either starts Cadence as if it would be called locally (or resumes all windows if the connection was lost).

Yaaaay! Nomachine NX combines the advantages of both VNC and F forwarding. Summarized all Features of this approach:

  1. Windows seamlessly integrate into client desktop (as if Cadence, MATLAB etc. would run locally), similar as X forwarding
  2. connection is persistent (when connection gets lost), as for VNC
  3. No problems with clipboard
  4. Access to local devices (not tried)

Awesome! Unfortunately the FreeNX package is outdated and buggy, but after 2 hours work I got it running

Client side (Windows)

Download the old (3.5) version of the NX client for Windows: https://www.nomachine.com/NX-3-5-0-Download-Package&Prod_Id=3835

rename: 

c:\Program Files (x86)\NX Client for Windows\bin\nxssh.exe

to 

c:\Program Files (x86)\NX Client for Windows\bin\mxssh.exe

download nxssh.exe from http://prdownload.berlios.de/freenx/nxssh.exe and copy it to c:\Program Files (x86)\NX Client for Windows\bin\

Connection settings: 

Server: @corn07.stanford.edu
Port: 22
Desktop: Unix, Custom
Login: nhammler@U:/afs/ir/users/n/h/nhammler/NX4U/bin/nxserver-usermode
Password: [SUNET password]
  • The "@" in front of the host name activates the nxssh wrapper (executes FreeNX usermode)
  • The "U:" after the username executes usermode nxserver
  • The path afterwards points to the nxserver-usermode binary

See source code: https://github.com/Fabianx/freenx/blob/master/freenx-utils/nxpublickey/nxssh-4US.c

Server side (corn)

First steps based on http://openfacts2.berlios.de/wikien/index.php/BerliosProject:FreeNX_-_Howto 

NX_DIR=$HOME/NX4U
  • edit etc/node.conf:
ENABLE_USERMODE_AUTHENTICATION="1"
ENABLE_PASSDB_AUTHENTICATION="0"
ENABLE_SSH_AUTHENTICATION="0"
COMMAND_MD5SUM="md5sum"

The last line is the most important one; it causes nxserver to fail without any useful messages. Hints found in: http://mail.kde.org/pipermail/freenx-knx/2012-March/009541.html

  • install libXpm libraries:

corn is a 64 bit system but nx requires the 32 bit version of this library. Download libxpm4_3.5.10-1_i386.deb from: http://packages.ubuntu.com/de/raring/i386/libxpm4/download

and copy (with Midnight Commander - can open deb files) CONTENTS/usr/lib/i386-linux-gnu/*.* to NX4U/lib
