use copyparty as a chromecast replacement:
|
|
* post a URL and it will open in the default browser
|
|
* upload a file and it will open in the default application
|
|
* the `key` command simulates keyboard input
|
|
* the `x` command executes other xdotool commands
|
|
* the `c` command executes arbitrary unix commands
|
|
|

the android app makes it a breeze to post pics and links:
|
|
https://github.com/9001/party-up/releases
|
|
(iOS devices have to rely on the web-UI)
|
|
|
|
goes without saying, but this is HELLA DANGEROUS,
|
|
GIVES RCE TO ANYONE WHO HAVE UPLOAD PERMISSIONS
|
|
|
|
example copyparty config to use this:
|
|
--urlform save,get -v.::w:c,e2d,e2t,mte=+a1:c,mtp=a1=ad,kn,c0,bin/mtag/very-bad-idea.py
|
|
|
|
recommended deps:
|
|
apt install xdotool libnotify-bin
|
|
https://github.com/9001/copyparty/blob/hovudstraum/contrib/plugins/meadup.js
|
|
|
|
and you probably want `twitter-unmute.user.js` from the res folder
