Portmir using screen

For those AIX lovers that have by destiny the need to play with Linux and cry because in Linux there is nothing like portmir... where there is a *like solution for this... screen... if you don´t know what screen is look at my previous post ... but here is how to configure it to share a session... 

As root:

   1. Set the screen binary setuid root.

       sudo chmod +s /usr/bin/screen

       sudo chmod 755 /var/run/screen

   2. Start screen

       screen -S portmir

   3. Verify the username with w

   4. Allow multiuser access in the screen session

       CTRL-A

       :multiuser on

   5. Grant permission to the remote user to access the session

       CTRL-A

       :acladd username

   6. The remote user can now connect to the session using

       screen -x root/portmir
