I am presently trying to use Atom editor to connect to a remote desktop server. I used the instructions from the link [https://docs.junolab.org/latest/man/remote/](https://docs.junolab.org/latest/man/remote/). I was successfully able to use `ftp-remote-edit` to remotely edit codes in the server machine (covered in Basic setup section). When I tried to do the same for REPL in my Atom editor (covered in Manual port forwarding section), I am unable to get any output. The REPL process keeps on going as shown in the figure.

Can anyone help?  
I am using Atom editor in Windows 10 to connect to Julia in Ubuntu 16.04.

Why do you need to use manual port forwarding instead of the automatic setup Juno provides for you?

I didn’t get you. What do you mean by ‘automatic setup’?  
I have a desktop server in the office which has 20 cores and a GPU. While I code in Julia, I check if each of the lines work using REPL. For example, I want to run the codes given in [https://juliagpu.gitlab.io/CUDA.jl/tutorials/introduction/](https://juliagpu.gitlab.io/CUDA.jl/tutorials/introduction/) this way.

Just follow the instructions at [Connecting to a Julia session on a remote machine · Juno Documentation](https://docs.junolab.org/latest/man/remote/#Basic-setup-1) instead of those at [Connecting to a Julia session on a remote machine · Juno Documentation](https://docs.junolab.org/latest/man/remote/#Manual-port-forwarding-1).

Yes, I did that. I was able to connect to the remote server for editing the files only. As you can see in the image below, I am connected to the i9quadro desktop server and am able to run the programs using Julia in the terminal below. I am however not able to run individual lines of code this way by pressing `Ctrl+Enter`. Based on the tutorial, this is possible if I do the manual port forwarding. Am I missing something trivial here?

Did you make sure to start the remote REPL as instructed? It should open a `REPL @ i9quadro` tab.

Yea I followed the instructions blindly, and it didn’t work. I then tried to read up on each of the instructions and couldn’t get anywhere. Based on the screenshots in the link I realised I am supposed to get a `REPL @ i9quadro` tab, but I couldn’t get it.

What happens when you execute the `Start Remote Julia Process` command (either from the command pane or the toolbar)?
