How do I have listen port be on the remote side

[lnee94]

I have a ssh server on the remote end that I want to forward to the local port in order I have to send {"kind": "local","endpoint": "tcp:22:interface=localhost","local-endpoint": "tcp:localhost:2222",} from the remote host. Is there a json string that does this on the local end.

"kind": "remote"

[meejah]

(I'm working on a branch that re-factors a bunch of CLI stuff, and improves the docs .. hopefully this will be more clear in there).

Basically both commands are the same, but "kind": "local" means the listener is "here" and "kind": "remote" means the listener is "there".

[meejah]

If the docs here: https://github.com/meejah/fowl/blob/15.split-cli/docs/messages.rst do make this clear from your perspective please let me know :)

[lnee94]

got it I'm look to build a app that manages sshfs waypipe and other stuff I was in a rut until I found this thanks for makeing it also I'm looking in to packageing this for debian

[lnee94]

Can you give an example for listen on local port 2222 and the remote host port 22 connect to a ssh server. I tried using the docs I it gives me error. I work better with examples thanks.

[meejah]

Cool, sounds like a nice app! My use-case is a pair-programming thing (started here https://git.sr.ht/~meejah/pear-on ).

Beware that I'm splitting this into fowld (for programs like yours or mine to use) and fowl for humans to use -- those efforts are in the branch above.

I'll make an SSH example and push it in the next hour or two to the branch https://github.com/meejah/fowl/tree/15.split-cli and ping you here.

An ssh-based workflow is actually one of my personal uses for this: set up a laptop <--> desktop SSH session over fowld and then when I go to the cafe or whatever, I'm still connected -- shows where the problems are :) like that Dilation / magic-wormhole itself could benefit from giving more feedback to Fowl so I can show the user something (like "re-connecting").

[meejah]

Also, Debian packaging would be great! Let me know if there are changes that help packagers :) (magic-wormhole etc already is packaged AFAIK).

[meejah]

Not sure how much this helps at the moment, mostly because I'm changing some of the names from what's in main, but does this clear it up a little?

I tried {"kind": "local", "listen": "tcp:1234:interface=localhost", "connect": "tcp:localhost:22"(note quote was missing)} in version 32.10.2 (pypi) I get

I also tested the split-cli branch (which compiled the deb first try) I could not get fowld to connect

[lnee94]

ok I figured out for fowld you need to run {"kind":"allocate-code"} and {"kind":"set-code","code":"1-hacker-way"} You get a lot of python errors and this as the debug output

If this isn't clear in the latest release (see e.g. https://fowl.readthedocs.io/en/latest/usage.html#common-fowl-options ) then please re-open this bug :)
