Issue
I have vagrant and an ubuntu server 16.04 box started with it.
By using vagrant ssh command everything is fine if you need just one terminal, but I need many terminal sessions not just one because I have to start 3 nodejs processes and some other tasks and need to monitor them while running.
Have searched a lot but haven't found any information about this issue. Over vagrant ssh can't event use ubuntu server virtual terminals ttys-
Solution
The easiest is to have as many terminal session open on your host than you need and for each you can run vagrant ssh.
If you want to have a single vagrant ssh running, you can look at software like screen or tmux
