Connect from a remote host?

[blablablerg]

Hello,

I am new to Julia, and I don't know how to find package documentation (yet), so I might ask a stupid question.

So I am trying to do the new julia course, but I run julia on a remote host (on the LAN). When I start Pluto.jl with Pluto.run(), I can connect to the server on the host itself but not over the network.

When I check netstat, I see that the server is listening on 127.0.0.1:1234. I think that I want this to be 0.0.0.0:1234, so that I can connect from a remote host.

Any of you know how to do that? Much appreciated. The host I want to use runs Debian.

Hi! You can do:

Pluto.run("0.0.0.0", 1234)

let me know if this works!

It does! Thank you.

(This syntax will change very soon - sorry in advance :)))))

Anyone have an update on this?

I'm SSH'ing to my computer's HPC and the regular way of getting a jupyter notebook is:

jupyter notebook --no-browser --ip=$(hostname -s) --port=8989

The hostname being something like the compute node: hpc3-22-04

And then in putty I would set it as done here

With
sourceport: 8989
Destination: hpc3-22-04:8989

Any advice?

If you want a one-liner that works from the terminal, this should do it.

julia -e "using Pluto; Pluto.run(host=\"0.0.0.0\", port=1234, launch_browser=false)"

Then you can open Pluto by going to hpc3-22-04:1234/?secret=<paste secret here>

@ctrekker Ok looks like rather than pasting the:
https://hpc3-22-04:1234/?secret=<paste secret here>
or
https://0.0.0.0:1234/?secret=<paste secret here>

I had to use:
https://127.0.0.1:1234/?secret=<paste secret here>
and it worked!

It's interesting that even when I specifically used that ip address:
Pluto.run(host="127.0.0.1", port=1234, launch_browser=false)

It didn't work.

Glad you found a solution! I'm guessing there's something on your computer acting as a proxy, since 127.0.0.1 would normally loopback to a server running locally. VSCode acts as a proxy in this manner if connected via SSH to the remote - maybe PuTTY does something similar.
