Cygwin Connection fechado por :: 1

Question

Durante a instalação do Hadoop, estou tentando configurar CYGWIN e ssh . Instalado e ssh também começou com sucesso e chave de autorização de instalação, conforme instruído AQUI , mas quando Eu tento me conectar ao localhost usando ssh diz ..

$ ssh -v localhost

Após vários googling , eu tentei ssh -v cyg_server@localhost , mas ele solicitou senha que eu não sei ..

Alguém por favor pode me ajudar a estabelecer uma conexão ssh bem-sucedida e autenticada com o localhost. Ou por senha ou criando outro usuário ou ignorando a etapa de autenticação. Seria ótimo para mim! Obrigado.

    

Answer 1

Aqui estão algumas possibilidades para experimentar:

1. Tente substituir 127.0.0.1 pelo localhost.
2. Verifique se a conta do usuário cyg_server tem um diretório inicial válido (crie /home/cyg_server , se necessário) e seu shell é /bin/bash .
3. Desinstale o Cygwin completamente, limpe seus diretórios e variáveis de ambiente, e reinstale. A senha a ser usada é aquela que você fornece ao configurar o Cygwin.
4. Tente usar sua conta normal em vez do cyg_server sugerido pela instalação do Cygwin.

Eu não entendo porque sua postagem está marcada como "linux" quando você está usando o Cygwin - deve neste caso, seja "windows". Neste caso, dê uma olhada neste artigo: Rodando o hadoop no Windows .

    

Answer 2

O usuário cyg_server não é destinado ao uso direto.

Verifique se o arquivo /etc/hosts está correto, verifique se ele resolve explicitamente o localhost para 127.0.0.1.

Se você não precisa de IPv6, desative-o.
