I'm running the erlang release of my elixir app via systemd on EC2 ubuntu. When I tried to run remote_console of my app via ssh, it works weird.

# Good way. Connect to EC2 and run remote_console

$ ssh ubuntu@<ip>
$ sudo myapp remote_console
iex(myapp@127.0.0.1)> Application.started_applications()
... # All of my applications. OK.


# Bad way. Run remote_console via ssh command

$ ssh ubuntu@<ip> sudo myapp remote_console
iex(remshce50beca-myapp@127.0.0.1)> Application.started_applications()
[{:logger, 'logger', '1.4.1'}, {:iex, 'iex', '1.4.1'},
 {:elixir, 'elixir', '1.4.1'}, {:compiler, 'ERTS  CXC 138 10', '7.0.4'},
 {:stdlib, 'ERTS  CXC 138 10', '3.3'}, {:kernel, 'ERTS  CXC 138 10', '5.2'}]
# Weird node name remshce50beca-myapp and only 3 applications are started.

I don't understand why those are different.

Try with `-t`: `ssh -t ubuntu@ sudo myapp remote_console`. – Dogbert May 18 '17 at 02:49
And to add some context to the answer marked as duplicate, `ssh` without `-t` will not give `$TERM` any value. `-t` will force allocating a TTY and a give a valid value for `$TERM` and should work here. – Dogbert May 18 '17 at 15:17
@Dogbert Thanks a lot! – mayTree May 19 '17 at 07:16
