Ao tentar SSH em um servidor (um recurso da universidade, eu posso ler arquivos de configuração, mas não editá-los) do Bash no Ubuntu no Windows, eu sempre recebo o mesmo erro:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,hostbased).
E o código de saída 255. Não me pedem uma senha.
Eu posso conectar-me a ele de outros computadores quando inicializado no linux, ou no Windows usando um cliente como o PuTTY.
Como faço para corrigir isso?
