Restart Services


Goorm will put container into sleep mode after a couple of hours. Your service might not automatically come up. In this case, you will need to manually restart your services:



root@goorm:~/.vnc# service --help
Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ]
root@goorm:~/.vnc# service --status-all
 [ + ]  apache-htcacheclean
 [ - ]  apache2
 [ ? ]  apport
 [ - ]  cron
 [ - ]  dbus
 [ - ]  hddtemp
 [ ? ]  hwclock.sh
 [ - ]  lm-sensors
 [ - ]  mysql
 [ - ]  procps
 [ + ]  ssh
 [ + ]  udev
 [ - ]  unattended-upgrades
 [ - ]  x11-common
root@goorm:~/.vnc# service apache2 restart
 * Restarting Apache httpd web server apache2
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.3. Set the 'ServerName' directive globally to suppress this message
   ...done.
root@goorm:~/.vnc#





Install VNC xfce desktop



Run following commands from terminal then you will have nice xfce deskotp through VNC protocol to use. Firefox will be installed as your browser.


sudo apt update
sudo apt install vnc4server -y
sudo apt install xfce4 xfce4-goodies -y
sudo apt install firefox -y
vncpasswd
sudo vncserver -geometry 1366x768

To run the VNC: sudo vncserver -geometry 1920x1080
Now, go to the container settings and do a port forwarding rule with the port: 5901

You do need a couple of extra steps to make it working:

  • From container setting page, enable VNC port:5901
  • Copy remote connection link to VNC for connection
  • Download VNC client from https://www.realvnc.com/en/connect/download/viewer/
  • Don't disconnect your SSH connection, else your desktop will not work. You will have to delete to re-deploy it again.






Note: Firefox in the following screenshot will cause your account blocked based on goorm's policy for the programs causing high computing resources.


Troubleshooting



If you only got a grey desktop after logged in and could not see anything else, you might need to change xstartup file a bit then  restart the vnc server to fix this issue.. 

Here are the steps:

1. Check which session your VNC server is running on.
In our case, it is running on :2 session, and port is 5902. You also can check logs at /root/.vnc/ folder to see the session related log messages.

root@goorm:~/.vnc# netstat -na

2. Modify /root/.vnc/xstartup file


root@goorm:~/.vnc# pwd
/root/.vnc
root@goorm:~/.vnc# ls
goorm:1.log  goorm:1.pid  goorm:2.log  goorm:2.pid  goorm:3.log  goorm:3.pid  passwd  xstartup
root@goorm:~/.vnc# cat xstartup
#!/bin/sh

DESKTOP_SESSION=xfce
export DESKTOP_SESSION
startxfce4
vncserver-virtual -kill $DISPLAY

root@goorm:~/.vnc#

3. Kill VNC Server session 2


root@goorm:~/.vnc# vncserver -kill :2

perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US.UTF-8",

    are supported and installed on your system.

Account Blocked

Goorm has tight policy to block account if there is policy violation. If you got following notice when you trying to log in, it is becasue of some programs installed in the container violating their policy.
