Terminal sharing?

bluehz · 06-24-2002, 07:47 AM

Is it possible to setup a terminal window for sharing?

What I need to do is do some live tutorials for someone in a remote location. Completely CLI oriented. What I would like to do is offer the ability to have the remote user (trusted user) login via ssh then be able to watch what I do in the terminal. Possibly chatting about the actions taking place in another terminal window.

Is this even feasible?

Get the VNC server and VNC clients from versiontracker.com and set them up to share the screen. You set up the server on your machine, the client could connect to your computer in read-only mode and watch what you do.

Yes - I thought about that and I do use VNC already. I was hoping for something with a little less overhead/bandwidth usage. I figured a straight telnet/CLI session would be lightning fast over even a modem connection.

look at the man pages for screen <which you can install with fink or compile it yourself from gnu.org>

"-x Attach to a not detached screen session. (Multi display mode)."

This works, across multiple machines... you will need to be using the same userid for it though! So make a special user just for training purposes.

Take a look as well at the options for multiple screens at once, and attaching and detaching screens.

There are articles online at places like samag.com and linuxdoc.org.

Have fun!

thx davidro - that sounds great. Matter of fact the person I am tutoring will be in Linux. I am helping them get up an running in Linux, the basics of unix , stuff, etc. - hence I want to be able to share terminal session for teaching.

Kool usage of screen. If your without screen, here's another way. I can't quite remember the syntax but I think this is correct. I'll try and test at school(I don't have 2 computers at home).

Code:

Pseudo code:
script something | tee oneMonitor@host:DISPLAY another@host:DISPLAY ...

Perhaps someone can fill in the details but that's the general fuzzy logic.

Yeah, but how do you type the

into the Terminal?

Yep, I'm a smart-aleck. Feel free to ignore me.

You can attach to another users screen if that user has a .screenrc file in it's home directory containing:
multisuer on
addacl someuser
Replace "someuser" with your username.

Example:

Code:

Tue 23:19 [erik @ /Users/erik] % cat .screenrc 
multisuer on
addacl root
