For VNC connections, TACC requires users to create an SSH tunnel from the local system to the Frontera login node to assure that the connection is secure. Note that gnome may lag over slow internet connections.ĭCV connections are encrypted via TLS and are secure. Gnome is available to use gnome, open the " ~/.vnc/xstartup" file (created after your first VNC session) and replace " startxfce4" with " gnome-session". The lightweight window manager, xfce, is the default DCV and VNC desktop and is recommended for remote performance. Login1$ touch dcvserver.out tail -f dcvserver.out Login1$ touch vncserver.out tail -f vncserver.out Watch for the "To connect" message at the end of the output file, or watch the output stream in a separate window with the commands: Note that the DCV viewer adjusts desktop resolution to your browser or DCV client, so desktop resolution does not need to be specified. The " vnc.job" script starts a vncserver process and writes to the output file, " vncserver.out" in the job submission directory, with the connect port for the vncviewer. ![]() Login1$ sbatch /share/doc/slurm/job.vnc -geometry 1440x900 For example, to set the desktop resolution to 1440x900, use:
