problema em estabelecer conexão ssh com um servidor remoto

Question

Quando eu uso este comando ssh someserver eu recebo o seguinte erro

Could not chdir to home directory /var/ak/home/username: No such file or directory
aksh: fatal error: user account has been deleted

aksh-wrapper: FATAL: The appliance shell failed unexpectedly with error code 1.

Eu tenho um diretório home em home_staff/username address, que é diferente do diretório home na mensagem de erro, mas não sei como corrigi-lo.

Com a opção -v , obtive o seguinte log

Your Kerberos account/password will expire in 7073 days.

Answer 1

A resposta é mostrada claramente nos registros:

Could not chdir to home directory /var/ak/home/username: No such file or directory
aksh: fatal error: user account has been deleted
aksh-wrapper: FATAL: The appliance shell failed unexpectedly with error code 1.

Acho que o problema precisa ser discutido com o administrador do sistema: parece que sua conta foi excluída no sentido de que, embora a autenticação tenha ocorrido (com uma possível falha), o diretório pessoal do usuário não existe mais .

A configuração atual do sistema leva a um status "conta encerrada" e a uma falha de login subsequente.

P.S. Você está executando um software muito antigo em ambos os lados! A atualização não irá " corrigir " o seu problema, mas poderá ajudar no futuro próximo com a segurança e outros problemas semelhantes.
