guru's machine

ssh noobs.machine.net
screen -x noob/assistance

To communicate, you can use the following command inside screen

ctrl-a :wall "my message"

Now you can change people's priviledges within the session. With the following command, noob can take away guru's write permission.

ctrl-a :aclchg newbie -w "#"

Now this doesn't make since here, but later we can see how guru can host a session for multiple noobs... now it definitely makes since for guru to only let the noobs have the ability to view the session. More on the next slide.

Either end, noob or guru, can log the session at anytime with the following command

ctrl-a H

or you can just start screen with the -l option. This can be very useful for guru if he is doing this commercially and he wants to keep a record of the support session. Noob can also use a log of the session to refer back to when he does the same thing again.
