Using TMUX as chat tool

Sometimes you need share a screen with one of your fellow linux admins and you don’t have Teams/WebEx or some other bullshit at hand.


  • Call your teammate via phone (for voice)
  • Both of you must open a ssh session to the same server
  • Install tmux (if not already installed)


# To Start a new session ...
tmux -S /tmp/socket
# Change the socket permissions to allow other users to access the session
chmod 777 /tmp/socket
# Other users can attach themselves to the session with command:
tmux -S /tmp/socket attach
