"no route to host"

[hmltn-0]

I believe I followed the set-up instructions.

1. Installed Docker
2. Created a smsn folder
3. Did the docker pull command
4. Used the process ID to open a bash shell and start emacs
5. Do the Emacs command M-x smsn

The screen turned blue, but it says C-c n is not recognized, and I think it gave me an error message:

Is this an error?

The screenshot you attached is a broken link for me. Could you paste the text of all the shell commands you ran?

Do the usual modifier keys work in Emacs for you outside of smsn-mode? For instance if you type C-u 8 a, do you end up typing 8 copies of the character a?

When you say the screen turned blue, do yout mean the Windows blue screen of death, or that Emacs turned blue?

Thanks. I fixed the image upload.

I meant Emacs turned blue, as the install instructions said - "if the screen turns blue, it's working". I'm on Mac.

Here is some of what I've entered in the shell:

Maybe it's because I'm new to Emacs. I think I wasn't able to do normal commands like Ctrl-x Ctrl-f because I was in the "mini buffer" where some Lisp debugging info is. I exited taht with Ctrl-g I think, then I could open a new file and Ctrl-u 8 a worked, for example.

But Emacs is still in split screen, and I can't close one of the buffers with Ctrl-0 or Ctrl-1, and SemSyn commands like Ctrl-c n are not recognized.

Cool, this is progress.

The error message in the right pane of your first uploaded image indicates that Emacs is not finding Gremlin. (Notice how each line ends in a dollar sign? That's to indicate it continues scrolling off the page. To wrap those lines you can run M-x to-tr, which expands to toggle-truncate-lines. In some modes the default is to wrap; in other modes, not to.)

Gremlin controls the graph, and Emacs is the frontend for it. Are you running Emacs from within the docker container, or from outside of it?

It's been a couple years since I used SmSn myself, but I love the project and want you to be able to use it, so I'll try to get it running myself soon and compare notes.

C-c n should create a new node if smsn-mode is running. That it doesn't suggests that it isn't. Do you still get the no route to host error shown in the second pane of your first upload? The output you showed from Gremlin, ending with started at port 8182, indicates that Gremlin is indeed running.

Sometimes Docker gives permission problems as a result of having a different uid and gid than the host system. From within Bash in the Docker container, if you touch a file and then view it using ls -l from the host system (outside of Docker), does it have the same user and group name as a file you create from the host system?
