Today , I run my Robotic Vision presentation on experimental server. Last day I did this, and presentation was accessed only, when my experimental terminal is opened. After that nobody can access it. But today, I knew that, I have done one mistake , I did not use tmux to run presentation. In the evening, I install tmux . Then type tmux on terminal and done all work that I have done yesterday to run presenation on terminal.I did this by self learning.
