This document describes some ways to share your terminal session using termcast.org.
Tested with OpenSSH, but should work with any
script is usually available in Linux (as a part of
util-linux) and OS X.
Choose a temporary username starting with
=. I'll use "=jason" for this example. Run 'check':
$ ssh =email@example.com check The authenticity of host 'termcast.org (18.104.22.168)' can't be established. RSA key fingerprint is SHA256:JvWo1jqg5jYBkHuiKsBjlI26r/eOw3uFhaNOTgfWImQ. Are you sure you want to continue connecting (yes/no)? yes Everything looks good.
Create a FIFO and connect it to termcast.org using
$ mkfifo termcast.pipe $ ssh =firstname.lastname@example.org broadcast --script < termcast.pipe > termcast.log &
You can use
broadcast --script --record instead to create a recording of your session.
script to start the shell in a shared terminal session:
$ script -q -f a.pipe -c 'sh -ic "PS1=tc\ \$PS1 exec bash --norc"' tc $
When done, exit the shell to quit the shared session:
tc $ exit $ + Exit 255 ssh =email@example.com broadcast --script < termcast.pipe > termcast.log $
Choose a username and maybe run
check as described above. Then, in
$ tmux pipe-pane 'ssh =firstname.lastname@example.org broadcast > termcast.log'
... to start sharing your session, and
tmux pipe-pane (without paramters) to stop sharing. You can bind that to a couple of hotkeys in
tmux, or just use the commands.
Finally, if you don't care about security at all, you can use termcast.org old broadcasting protocol. It's still supported for legacy clients. You need to choose a temporary username (we'll use jason for this example), and a temporary password (we'll use fredfred here). Then, make a FIFO as described above, and use
nc (netcat of some sort) to start sharing:
$ (echo hello jason fredfred; cat) < termcast.pipe | nc termcast.org 31337 > termcast.log & $ script -q -f termcast.pipe -c 'sh -ic "PS1=tc\ \$PS1 exec bash --norc"' tc $
