• Go to Project → Compute → Instances menu (Step A), and check your VM instance is in Running Power State (Step A). From the Actions pull-down menu, choose Console.

• Click on the black console screen, and log in with root username and temporary password (Step B).

• First, change the root password and update the OS. Create a user account. Install desktop environment & remote desktop server.

  Code Block
  language bash theme Midnight title configure VM instance : remote desktop linenumbers true
  ### Change root password $ passwd ### Update OS $ apt update && apt -y dist-upgrade ### Create a user account (recommended) : adduser {username} $ adduser kasi-user ### Grant sudo privilege to the user : usermod -aG sudo {username} $ usermod -aG sudo kasi-user ### Install dekstop environment (minimal installation is recommended) $ apt install xfce4 --no-install-recommends ### Install remote desktop server (RDP) $ apt install xrdp ### Reboot $ reboot

  
  

• After reboot, log in to the console with the user account, and configure SMB client to mount user's external datastore (Step C).

  Code Block
  language bash theme Midnight title configure VM instance : external datastore linenumbers true
  ### Install required pacakges : cifs-utils, smbclient $ sudo apt -y install cifs-utils smbclient ### Create a mount directory $ mkdir NAS ### Mount external datastore : mount.cifs -o rw,uid={local user},username={NAS user} {NAS address} {mount directory} $ sudo mount.cifs -o rw,uid=kasi-user,username=kasi-user //210.219.33.249/home NAS ### For more mount options : man mount.cifs ### Check if external datastore is mounted and the user has write permission $ df -H ; ls -l ### log out $ exit

  
  

5. Remote access to VM instances via SSH tunneling

• Prepare the SSH keys (the same ones you registered in sign-up form). If you want to register another key pairs, e-mail the SSH public key file to Administrator(chr@kasi.re.kr).

• Go to Project → Compute → Instances menu, and find the public IP address (e.g., 210.219.33.X) of project gateway (e.g., User Project Gateway) from the instance list (Step A).

• Install Remote Desktop Protocol (RDP) client software to your local computer, and set up the remote connection.

  • If RDP clients support SSH tunneling – remmina (Linux), MobaXterm (Windows), configure RDP session as follows:
    • Remote host address (10.0.X.X) : VM instance private IP (port 3389)
    • Remote host username : user account you created (recommended) or root
    • SSH gateway address (210.219.33.X) : project gateway public IP (port 7774)
    • SSH gateway username : kasi

  • If RDP clients do not support tunneling – CoRD (Mac), Microsoft Remote Desktop (Mac), create a SSH tunneling port first and connect through the local port. 

    Code Block
    language bash theme Midnight title create local RDP port for SSH tunnel linenumbers true
    ### SSH tunneling : ssh -i {private key} -N -L {local RDP port}:{VM instance private ip}:{RDP port = 3389} {tunneling id = kasi}@{gateway ip} -p {ssh port = 7774} $ ssh -N -L 12345:10.0.100.42:3389 kasi@210.219.33.122 -p 7774 ### Open RDP connection through localhost:{local RDP port} $ open rdp://localhost:12345
