Eu tentei modificar meu arquivo ~/.ssh/config para permitir o encaminhamento X rápido automático conforme este site
link
Eu tentei entrar em um servidor e rodar xeyes apenas para ver se as coisas estavam funcionando. Eles não eram. Parece-me que nada está lendo o arquivo de configuração.
Esses sites sugerem que as permissões de home devem ser 755 ou menos; .ssh deve ser 755 ou menor; config 644 ou menos. As permissões que estou usando são 750 (home), 700 (.ssh) e 644 (config). Nada ainda. Alguma idéia?
Editar1: conforme solicitado nos comentários.
