Requirements to be done only the first time:

In Stiletto:

1)) Set the VNCserver:

  • Set password for your VNCserver:
[eecheverria@PEB-SRVNIX-STILETTO ~]$ vncpasswd
  • Edit ~/.vnc/xstartup file:
[eecheverria@PEB-SRVNIX-STILETTO ~]$ vim ./vnc/xstartup

Delete everything and write this:

#!/bin/sh
##unset SESSION_MANAGER
#unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

#twm &
metacity &
#nautilus &
  • Give execute permission to xstartup:
[eecheverria@PEB-SRVNIX-STILETTO ~]$ chmod  u+x ./vnc/xstartup

Run app

In stiletto:

  • Check which of the ports are not being used so that you can use them. The port is the number after the semicolon (:)
[eecheverria@PEB-SRVNIX-STILETTO ~]$ ps -ef | grep vnc
hayden    5101     1  0 Nov18 ?        00:00:29 /usr/bin/Xvnc :1 -auth /home/hayden/.Xauthority -desktop PEB-SRVNIX-STILETTO:1 (hayden) -fp catalogue:/etc/X11/fontpath.d -geometry 1600x1050 -pn -rfbauth /home/hayden/.vnc/passwd -rfbport 5901 -rfbwait 30000
cpfluger  9288     1  0 Nov19 ?        00:00:00 /usr/bin/Xvnc :34 -auth /home/cpfluger/.Xauthority -desktop PEB-SRVNIX-STILETTO:34 (cpfluger) -fp catalogue:/etc/X11/fontpath.d -geometry 2560x1440 -pn -rfbauth /home/cpfluger/.vnc/passwd -rfbport 5934 -rfbwait 30000
  • Start the VNC server (I am using port 23):
[eecheverria@PEB-SRVNIX-STILETTO ~]$ vncserver  :23

In your local PC:

  • Open the ssh tunnel to the VNCserver:
kike@kike-X541UA:~$ ssh -N -Y -f -L 59<Port>:127.0.0.1:59<Port> stiletto
  • Open the VNCViewer and start the connection by typing 127.0.0.1:59#PORT# and enter the password you used when you ran vncpasswd.

Tip: In the VNCViewer session right-click>Properties>Options and set Picture quality to Low (it will go faster).

In the VNCViewer terminal:

[eecheverria@PEB-SRVNIX-STILETTO ~]$ cd /scratchfs/<USER>  
[eecheverria@PEB-SRVNIX-STILETTO ~]$ /usr/bin/Rscript /dd_public/www/listerlab/kike/human_sc_brain_shiny/my_app.R

After closing the app

Remember to close IN stiletto the VNCserver port and to kill the .logs file

[eecheverria@PEB-SRVNIX-STILETTO ~]$ vncserver -kill :<PORT>  
[eecheverria@PEB-SRVNIX-STILETTO ~]$ rm ~/.vnc/PEB....log...
