msm <server> console not working

[netgoatfr]

Hello! I recently installed Msm and created a server. When i try execute the command in the title, with sudo or without, it prompt me to the sudo login, with the default user or my linux account.At first, it was not working because i didn't know the minecraft user's password. So i change it to my account in the default config. Now, it prompt me my password for sudo, and after I type this right, it bring me back to the shell and tell me "[screen is terminating]". I didn't pressed CTRL+C or CTRL+A . Can someone tells me what am I doing wrong ?
Thanks in advance for any anwser. (Sorry for my language I'm not english native)
