Sharing a Screen Session
Let’s assume that I elubow want to share my console with jdoe. The easiest way to do this next part is to actually name your screen session. So let’s call our session test.
$ screen -S test
This will create the session and put you in it. Now we need to add the access control. Note: You can automate the multiuser piece by adding it to you .screenrc.
All jdoe has to do now is connect to the same machine and type the following command:
$ screen -x elubow/test # $user/$session_name
There are other security combinations as the above gives jdoe full access. Here are a few common ones:
:aclchg user +rx # Give 'user' read-only access
:aclchg user -x "#,at,aclchg,acladd,acldel,quit" # Don't allow 'user' any of the previous commands
:aclchg user +rwx # Give 'user' read-write access (open permission on the session)
