Eu tenho 3 servidores (Ruby, Sapphire, Onyx) que venho tentando configurar a autenticação sem senha (baseada em host) entre todos os usuários. Eu configurei as máquinas para usar autenticação baseada em host e modifiquei o ssh_config, sshd_config, shosts.equiv e ssh_known_hosts por este guia .
Estou encontrando esse erro, no entanto, quando tento conectar-me de uma das máquinas (Ruby) a uma das outras (Sapphire):
get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,hostbased).
Por favor, informe.
Eu posso fornecer arquivos de configuração e saída detalhada a pedido, prefiro não postar isso no começo, a menos que seja necessário devido ao volume.
Editar 1: Todos os servidores estão executando o OpenSSH_5.3p1 no Centos 6.8
Edite 2: Saída do modo de depuração SSH -vvv:
