Tengo un enrutador configurado en VirtualBox. Puedo acceder a él desde la consola, pero no tiene un búfer de desplazamiento y no puedo seleccionar con el mouse. Estoy intentando acceder a él como root. Utiliza dropbear.
Salida desde abajo:ssh [email protected] -vvv -o PreferredAuthentications=password -o PubkeyAuthentication=no

¡Eliminé mi Cygwin SSHD local y ahora lo hago ssh: connect to host 192.168.1.1 port 22: Connection refusedaunque mi computadora host tiene una dirección IP 10.0.0.*! Entonces me queda acceder con [email protected] -p 2222lo que da un error.
Eliminé 2 reglas de iptable pero no ayudó. Mismo error ssh_exchange_identification".

Respuesta1
La configuración predeterminada de dropbear no permite SSH con contraseña desde la interfaz WAN.
Según el resultado anterior, parece que estás usando la interfaz NAT de Virtualbox, por lo que esto es lo esperado.
Mire /etc/config/dropbearel enrutador para confirmar y cambiar la configuración predeterminada.
config dropbear
option PasswordAuth 'on'
option Port '22'
option Interface 'lan'
config dropbear
**option PasswordAuth 'off'**
option Interface 'wan'
option Port '2022'
también verificar
opción RootPasswordAuth 'activada' opción RootLogin 'activada'
si es necesario, o al menos la exclusión de
opción RootPasswordAuth 'desactivada' opción RootLogin 'desactivada'
estas opciones por defecto son verdaderas
