    !!! note Visualisation server is a compute node. You are not able to SSH with your private key. There are two solutions available to solve login issue.

    Windows Users

    Solution 1 - Add the public fingerprint

    • Generate public fingerprint for your private key with PuTTYgen

    • Add this key to ~/.ssh/authorized_keys on the cluster

    • Use your standard SSH key to connect to visualization server

    Solution 2 - Copy private key from the cluster

    • Add path to key file

    • Save
    • Copy ~/.ssh/id_rsa to your computer
    • Convert key to PuTTY format with PuTTYgen

    • Use this new ssh key to connect to visualization server

    Install PuTTY

    • Add credentials and key file (create 3x sessions: vizserv1.salomon.it4i.cz, vizserv2.salomon.it4i.cz, login1.salomon.it4i.cz)
    • Config SSH tunnels (user-computer) (for sessions vizserv1 and vizserv2 only) - ports: 5901, 5902, 7300-7305

    • Save

    Run VPN client [VPN IT4Innovations][f] (user-computer)

    Login to Salomon via PuTTY (user-computer)

    $ ssh salomon.it4i.cz

    Remove ~/.vnc/xstartup

    Run job

    $ qsub -I -q qviz -A OPEN-XX-XX -l select=1:ncpus=4:host=vizserv1,walltime=04:00:00 -N Vizserver1
$ qsub -I -q qviz -A OPEN-XX-XX -l select=1:ncpus=4:host=vizserv2,walltime=04:00:00 -N Vizserver2

    Run vncserver on vizservX

    • check existing vncservers in /tmp/.X11-unix/X* (rm /tmp/.X11-unix/X1 /tmp/.X11-unix/X2)
    • vizserv1: vncserver :1 -geometry 2540x1380 -depth 24
    • vizserv2: vncserver :2 -geometry 2540x1380 -depth 24
    • set password for vncserver

    Login to vizservX via PuTTY (vizserv1/vizserv2) with tunnels (user-computer)

    Run NICE DCV (user-computer)

    • vizserv1: localhost:5901
    • vizserv2: localhost:5902
    • fill password

    Check DCV status (Salomon-vizservX) in VNC window

    Run glxgears (Salomon-vizservX)
