MATLAB on TSP Linux servers

■ 3 releases available on TSP Linux servers

2010a

MATLAB = /opt/matlab-disi-R2010a

2015a

MATLAB = /opt/matlab-disi-R2015a

2018b

MATLAB = /opt/matlab-disi-R2018b > to be used in this course

Main routine

MATLAB/bin/matlab

■ System configuration

/usr/local/bin/matlab is a symlink on the 2010a release

► update PATH in your $HOME/.bash_profile

PATH=/opt/matlab-disi-R2018b:$PATH

Software requirements

■ 2 software components are required to enable your computer

to support GUI applications running on a remote Linux host

A X11 Server to provide your computer with X Windows-

compliant local display & interaction capabilities

A SSH client supporting the X11 Forwarding mechanism

to secure the local X11 session

► third-party client ► native ► third-party client ► native

Displaying MATLAB GUI on your computer

■ A 3-step process

First, start an X11 server on your computer

► Your computer now listens for client connections from GUI

applications running on remote Linux hosts

Open an X11 Forwarding-enabled SSH connection to

sshmaster.imtbs-tsp.eu

► Your computer can now securely support any GUI application

running on sshmaster.imtbs-tsp.eu

Launch matlab from the command line

► MATLAB GUI connects to your local X11 server for display / input

■ OS-specific details are provided hereafter

SSH connection to TSP Servers

■ Enable X11 Forwarding

Edit the system sshd_config file in /etc or /etc/ssh

► set / insert option X11Forwarding yes

■ Open a SSH connection to sshmaster.imtbs-tsp.eu

Open a macOS Terminal or an xterm in XQuartz

− On the command line, open a SSH connection using the –Y

ption to turn on Trusted X11 Forwarding

ssh -Y sshmaster.imtbs-tsp.eu

SSH connection to TSP Servers

■ Most Linux distributions have an X11 Server installed ■ Open a SSH connection to sshmaster.imtbs-tsp.eu

Open a SSH terminal client

► X11 Forwarding is set by default

− On the command line, open a SSH connection using the –Y

ption to turn on Trusted X11 Forwarding

ssh -Y sshmaster.imtbs-tsp.eu
