Estou instalando um OrangePi (mais poderoso que o do Rasp). Depois de instalar o sistema com o usuário root padrão, eu gostaria de adicionar um novo usuário e conectar-me a partir do ssh
adduser foobar
Eu obtive todos os arquivos criados /home/foobar
Mas não consigo mudar de usuário
# su foobar
#
Além disso, quando tento me conectar a partir do ssh
ssh foobar@ip
A conexão fecha logo depois.
Se eu ssh -v -v -v foobar@ip
OpenSSH_6.9p1, LibreSSL 2.1.8

Alguma ideia?
Desculpe por responder, não comentar.
A situação que você mostrou acontece porque o usuário foobar não possui um shell padrão.
Para verificar isso, tente executar su desta maneira: su -s /bin/bash foobar as root.
Se foobar@pi e o cifrão aparecerem, minha resposta está correta.
