ssh sem senha funciona para raiz, mas não para outros usuários

-1

Eu fiz o seguinte para usuários root e orainst,

  • Eu adicionei id_rsa.pub da primeira máquina ao authorized_keys da segunda máquina
  • Eu tenho 700 permissões na pasta .ssh

ssh sem senha funciona para root, mas não para orainst.

o usuário orainst não tem uma senha (eu gerava usando o livro de receitas do Chef) se isso faz diferença

aqui está a saída de ssh --vvv para orainst

Você poderia compartilhar o servidor depurar logs em vez disso?
grawity
Você viu atentamente a saída? "Não é um arquivo de chave RSA1 /tools/appsw/oracle/orainst/.ssh/id_rsa." O arquivo de chave privada que você está usando está aparentemente incorretamente formatado.
mdpc
Outra observação, a chave privada não deve estar em um arquivo de chave autorizado ... ou seja, para todas as chaves públicas que você reconhece.
mdpc
@mdpc o que fez você pensar que eu tenho chave privada em authorized_keys? Eu colei a chave pública em chaves autorizadas da segunda máquina
Medya
@mdpc Eu gerava as chaves privadas usando ambos os comandos "ssh-keygen -t rsa" e ssh-keygen ambos não funcionam

O problema crítico parece ser que sua segunda máquina não aceita a chave pública, mas aceita a chave pública raiz. No segundo log estas linhas aparecem: 

debug2: we sent a publickey packet, wait for reply
debug3: Wrote 368 bytes for a total of 1645
debug1: Server accepts key: pkalg ssh-rsa blen 277

Mas no primeiro log, a terceira dessas linhas não aparece.

Uma possibilidade é que você não tenha digitado a chave pública do orainst corretamente no arquivo authorized_keys da segunda máquina. Por exemplo, pode ser necessário um fim de linha no final da chave ou a entrada de chave em authorized_keys pode ser dividida em várias linhas?

Outra é que, porque você não especificou o usuário remoto para a máquina remota, ele está tentando efetuar login como um usuário errado ou inexistente (provavelmente 'orainst', isso depende das configurações em seu arquivo local .ssh / config). Experimentar: 

ssh [email protected]

Esta 'força' tentou login como root na máquina remota.

@godoud Eu olhei para o arquivo authorized_keys que está em uma única linha
Medya
@Medya - e a linha termina com LF?
gogoud
para ambos (root e orainst) vim mostra ($) para o fim authorized_keys
Medya
@Medya - tente (para orainst): ssh [email protected] -vvv Eu acho que isso pode funcionar e é uma boa prática para fornecer o nome de usuário de qualquer maneira.
gogoud

Eu acredito que a diferença no comportamento é devido a diferentes permissões nos diretórios home dos usuários. No meu caso, as chaves não seriam processadas se o diretório home do usuário na máquina remota tivesse permissão de gravação para qualquer um que não o usuário, então drwxrwx --- não é bom, mas drwxr-xr-x funcionava. Normalmente, o usuário root terá seu diretório pessoal criado corretamente, mas os usuários podem variar. No meu Oracle Linux 6.7, o log do daemon sshd era / var / log / secure, e o acompanhamento mostrava que o daemon não processaria a chave pública, já que o diretório inicial do usuário tinha permissões incorretas.
