Adding non-interractive option

[mohzulfikar]

Maybe we can create an option so that we can run tty-share without pressing enter? @elisescu @matthewstrasiotto. thank you

[antifob]

Since tty-share provides shell access to the machine on which it runs, requesting user input is quite sensible. If it didn't require user interaction, it would be easy to abuse for malicious purposes.

[elisescu]

I think it might make sense to have a flag like that, but have it default to the current behaviour. I could imagine that it would be useful to not require pressing Enter in certain cases. I may look into it at some point, but I have very little time now. Feel free to push a change with that, if you want , @mohzulfikar :)

[artificiel]

it would be great to also be able to pass a command that is executed, for example setting up a Curses "service" that runs unattended, but available via tty-share.

[elisescu]

If I get what you're saying, @artificiel , then you can already do that with the two flags: --command and --args. Check that out

[artificiel]

yes these flags are great, but hitting Enter is still required, so not possible to spawn unattended.

[artificiel]

to be clear: using something like screen -d -m /path/to/tty-share --command service.sh

[strazto]

not saying this is ideal, but does piping in echo " " | tty-share work to simulate a newline?

[artificiel]

ha! well the echo idea was nice but does not work it say Input not a tty (at least on linux 4.15.0 x86_64)

BUT noodling around the idea led me to tmux which has a send-keys command. so this works:

tmux new-session -d -s tshare tty-share_linux-386 -listen some.host.net:4444 --command /usr/bin/top && tmux send-keys -t tshare: "Enter"

if you want to actually re-attach to the tmux session (so answering the initial request of "not having to press enter") you can append && tmux attach -t tshare: and keep on trucking with the process with the Enter taken care of.

it's quite some funny stuff, thinking about it.

(note: perhaps it would be feasible with screen too but tmux proved more straightforward to harness)

Tbh I'm not too surprised, as it was kind of a hack anyway. I think the request is valid in any case, wanting to launch non-interactively is a valid requirement sometimes (without needing hacky workarounds like weve described).

Here's the offending line, it could either be removed, or a new option --headless could be given

[elisescu]

@mohzulfikar , @strazto I've added a small change to add that. Have a look: https://github.com/elisescu/tty-share/releases/tag/v2.3.0

As always, any feedback is appreciated.

[elisescu]

Closing this, as --headless is an option with the new version
