    Interesting, but…

    What happens if the targeted user logged in on a GUI? I’m using Ubuntu 17.04 with Cinnamon desktop.

    The opened terminals aren’t receive messages sent by wall. Even if I enable receiving with “mesg y”. Why?

    And why I get these messages on the console if I disable them with “mesg n” (mesg n is the default)

    • Aaron Kili says:


      If a targeted user logged in from the GUI, then he or she may not see the message. You can only see the message if your terminal emulator is running by the time it is sent. Lastly, if the superuser(root) is sending the message, even if a normal user sets “mesg n”, he or she will see the mesg. But it will block one normal user’s message to another normal user.

      Hope you understand this explanation.
