Eu tenho vários usuários que eles se conectam ao meu servidor de seus clientes (clientes específicos) através do SSH, então eu gero para eles AuthorizedKeys .
Agora eu tenho dois Usuários, UserA e UserB , eu quero que esses usuários possam se conectar ao meu Servidor com qualquer dispositivo ou qualquer endereço IP, o ponto é que eu não quero fazer Chaves de Autorização para eles.
É possível?
Agora, quando eles querem se conectar ao servidor, diz,
permission denied (publickey)
Até tento adicionar esta linha ao sshd_config:
AllowUsers UserA UserB
Mas o resto da equipe acabou de ver
permission denied

# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes
UseDNS no
depois de fazer isso:
Match User UserA UserB
PasswordAuthentication yes
PubkeyAuthentication no
Match all
mas me mostra novamente:
Permission denied, please try again.
