Execute ssh -vvv durante sua conexão para um registro estendido do que está acontecendo. Meu instinto de que você tenha algo parecido com / bin / true para um shell, de modo que ele seja desativado por padrão.
Isso é o que acontece:
ssh [email protected]
password: something
Connection closed
Alguma idéia de por que isso acontece?
Atualização:
Aqui está o que acontece quando eu faço ssh -vvv
name@server% ssh -vvv [email protected]

Execute ssh -vvv durante sua conexão para um registro estendido do que está acontecendo. Meu instinto de que você tenha algo parecido com / bin / true para um shell, de modo que ele seja desativado por padrão.
Seu shell não pode ser iniciado por algum motivo. Provavelmente culpados são sistemas de arquivos completos (como / var / log) ou algo errado com o executável do shell real (ou seu arquivo de configuração).
Se você tiver algum tipo de IPMI, poderá acessar o console e ver se há algum dado relevante? Situações como essa são o ponto de venda para sistemas de gerenciamento fora de banda, como o iLO / DRAC / ILOM.
Um problema de permissão seria meu primeiro palpite ...
