Estou no Windows 10. Preciso fazer ssh em um servidor Linux CentOS. Tentando o Putty e o Windows SSH (ativado em Recursos. Powershell?).
Usando PuttyGen, gerei um par de chaves RSA públicas e privadas - rsa & rsa.pub , sem nenhuma senha longa. Ambos os arquivos estão na minha área de trabalho. server333 tem uma entrada em C:\Users\johndoe.ssh\known_hosts. Não há outros arquivos ou diretórios nesse diretório .ssh no meu PC com Windows. A chave pública também é copiada para /home/johndoe/.ssh/authorized_keys da caixa Linux
Eu tentei ssh -i rsa -vvv server333
, mas não está funcionando. Aqui está o registro:
c:\Users\johndoe\Desktop>ssh -i rsa -vvv server333

Parece que você não definiu o nome de usuário no servidor host SSH.
você ainda pode fazer isso, mas deve definir o user
arquivo de configuração SSH como:
vi ~/.ssh/config
...
Host server333
HostName your-server333-ip
User your-user
IdentityFile your-private-key
Então você pode remotamente o servidor com:
ssh server333
Nota: Certifique-se de que o arquivo de configuração tenha 600
permissão

O comando que vocêdissevocê executou é diferente do comando que vocêna verdadecorrido.
O que você disse que fez:
ssh -i johndoe_privatekey -vvv server333
O que você realmente fez:
ssh -i johndoe_privatekey.pub -vvv server333
Aqui vemos o ssh reclamando que não consegue encontrar o arquivo-chave que você especificou.
debug3: Failed to open file:C:/Users/johndoe/Desktop/johndoe_privatekey.pub.pub error:2
debug1: key_load_public: No such file or directory
Elimine o .pub
sufixo do comando, certifique-se de que os arquivos-chave estejam realmente presentes e tente novamente.

key_load_public: formato inválido
Putty e PowerShell geram/usam diferentes formatos de chave. Com o SSH, todas as estrelas devem estar alinhadas e provavelmente você não está usando o formato de chave correto devido a inconsistências entre o PowerShell e o Putty. Se você gerou uma chave no Putty e carregou a chave pública correspondente no servidor, não poderá fazer login via PowerShell, pois ele espera um formato de chave diferente.
Eu tentaria regenerar as chaves e começar do zero. Certifique-se de manter as coisas consistentes desta vez. Se você gerou uma chave RSA com o PowerShell, certifique-se de carregar a chave pública RSA correspondente (também gerada pelo PowerShell) para o servidor.
Pode ser mais fácil simplesmente gerar pares de chaves separados para PowerShell e Putty. Você precisaria então fazer upload de ambas as chaves públicas (uma para Putty e outra para PowerShell) para seu arquivoauthorized_keys no servidor.

Finalmente descobri - Existem 2 problemas aqui:
Se você não especificar um nome de usuário, o SSH do Windows será padronizado como DOMAIN\johndoe (que é obviamente um nome de usuário do Windows), enquanto o servidor Linux espera apenas johndoe. Para corrigir esta chamada
ssh johndoe@server333
em vez dessh server333
e, em seguida, tentar inserir o nome de usuário.Também exige que os nomes dos arquivos tenham permissões restritivas (somente você, o proprietário, deve ter permissões, ninguém mais deveria). Para corrigir isso, remova todos os outros usuários das permissões de segurança do arquivo
Depois que fiz as duas coisas, funcionou perfeitamente. Você não precisa colocar a chave pública na pasta local home/.ssh. Você pode simplesmente nomear sua chave privada como id_rsa (sem qualquer extensão), colocá-la na pasta home/.ssh e conectar-se ao servidor usandossh johndoe@server333
