Simple vnc connection problem

[DevinBayly]

I can't follow the instructions to start a connection to this docker container running in a remote server from my laptop (ubuntu 20.04).

Here's what I've tried running on the remote server

docker run -p 5900:5900 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vn

which outputs

2021-01-30 18:24:34,824 CRIT Supervisor is running as root.  Privileges were not dropped because no user is specified in the config file.  If you intend to run as root, you can set user=root in the config file to avoid this message.

but I've tried connecting with a bunch of VNC programs and none of them work

I used remmina with this configuration , but it times out without connecting.

I tried tightvncconnect myserverip in the terminal but it doesn't output anything or bring up any new graphical applications.

I'm sure I'm missing something super basic, so hopefully this isn't a tricky one. Thanks for the help!

Hi @DevinBayly ,

Herewith the command i run to start my container.

docker run \ -d \ -p 47387:443 \ -p 6885:5900 \ -v /dev/shm:/dev/shm \ -e RESOLUTION=2560x1440 \ -e VNC_PASSWORD=yourvncpwd \ -e USER=dennis \ -e PASSWORD=youruserpwd \ -e SSL_PORT=443 \ --cap-add=SYS_PTRACE \ --mount source=ubuntu-desktop-home-dennis,target=/home/dennis \ --mount type=bind,source=/etc/localtime,target=/etc/localtime \ --mount type=bind,source=/root/ssl/ubuntu-desktop,target=/etc/nginx/ssl \ --restart=always \ --name ubuntu-desktop \ dennisvanderpool/ubuntu-desktop

I've created a Dockerfile based on this one.

If that still doesn't work try checking if port might be blocked on the firewall (check iptables) or check --network argument

@dennisvanderpool Thanks for the info! What program are you using for your vnc client if I may ask, and do you just make it connect to the host ip running the container on port 6885?

[dennisvanderpool]

@DevinBayly Remmina on Linux and used 2 different VNC clients on Windows, they all work.

[DevinBayly]

alright good to know. I was able to connect using the turbovnc client and the ./vncviewer with the hostip::6885 and then my provided password.

Couldn't get remmina, but that's ok. Thanks for your help!
