Depois de configurar a autenticação de chave para o SSH, estou com o seguinte erro:
ssh remoteHost
System is going down.
Connection to remoteHostAddress closed by remote host.

O resultado ssh -vvv:

O erro de segurança do log var é:
fatal: Access denied for user finman by PAM account configuration [preauth]
Por isso, tentei soluções alternativas diferentes para ligar e definir UsePAM para no permitiu-me poder ligar via ssh ao servidor.
pam.d / sshd:
#%PAM-1.0
auth required pam_sepermit.so
auth substack password-auth
auth include postlogin
# Used with polkit to reauthorize users in remote sessions
-auth optional pam_reauthorize.so prepare
account required pam_nologin.so
account include password-auth
password include password-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session required pam_loginuid.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open env_params
session required pam_namespace.so
session optional pam_keyinit.so force revoke
session include password-auth
session include postlogin
# Used with polkit to reauthorize users in remote sessions
-session optional pam_reauthorize.so prepare
Depois de pesquisar e experimentar soluções diferentes, não encontrei uma maneira de manter o PAM ativado e conectar-se ao servidor.
Mais informações: conectando de um mac a um remoto do CentOS 7
A questão é, alguém sabe porque o PAM bloquearia a conexão ssh via pubkey?
Obrigado
