(Fig. 4-A) Go to Project → Compute → Instances menu, and check your VM instance is Running in Power State. From the Actions drop-down list, choose Console.
- (Fig. 4-B) Click on the black console screen, and type in root as username and temporary password you set in the previous step.
Change the root password and update the OS. Create a user account (recommended). Install desktop environment and remote desktop server.
Code Block language bash theme Midnight title (Cmd. 4-1) 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 -y install xfce4 --no-install-recommends ### Install remote desktop server (RDP) $ apt -y install xrdp ### Reboot $ reboot(Fig. 4-C) After reboot, log in to the console with the user account, and configure SMB client to mount user's external datastore.
Code Block language bash theme Midnight title (Cmd. 4-2) 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={user id},gid={group id},username={NAS user} {NAS address} {mount directory} $ sudo mount.cifs -o rw,uid=kasi-user,gid=kasi-user,username=kasi-user //210.219.33.249/home NAS ### For more options : man mount.cifs ### Check if external datastore is mounted and the user has write permission $ df -H ; ls -l ### DO NOT forget to log out $ exitInfo You can also mount the external datastore to your local desktop as a network drive : e.g., \\210.219.33.249\home (Windows file manager, address bar), smb://210.219.33.249/home (macOS finder, Go → Connect to Server)
Info WARNING: NEVER leave the console screen logged in. Other users CAN access your console.

Prepare the SSH keys (the same ones you registered in sign-up form). If you want to use another key pair for remote access, e-mail the SSH public key file to Administrator(chr@kasi.re.kr).
- (Fig. 5-A) Go to Project → Compute → Instances menu, and find from the instance list :
- private IP address (e.g., 10.0.X.X) of your VM instance
- public IP address (e.g., 210.219.33.X) of project gateway (e.g., User Project Gateway)
Install Remote Desktop Protocol (RDP) client software to your local computer, and set up the remote connection.
- (Fig. 5-B) 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 (root is NOT recommended)
- 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 in your local desktop first, and connect through the local tunneling port.
Code Block language bash theme Midnight title (Cmd. 5-1) 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
- (Fig. 5-B) If RDP clients support SSH tunneling – remmina (Linux), MobaXterm (Windows), configure RDP session as follows:
- (Fig. 5-C) Connect to the RDP host. If everthing (e.g., desktop environment, external datastore,...) works fine, you're all set.
